java-rest-binding's Issues

Version 1.7.2 to maven repo?

I need the fix "RestPathParser zero length path" for neo4j-scala.

Is it possible to release java-rest-binding version 1.7.2 to the Neo4j Maven repository?

(1.7 is the last available version)

RuntimeException is thrown when calling getOrCreateNode in batch mode

The following code segment works fine if calling from RestAPI directly.

RestNode userNode = restApi.getOrCreateNode(restApi.index().forNodes("user-id"),
                "user-id", userId, null);
        if (userNode != null){
            logger.debug("user node " + userNode.getId() + " is created.");
        }

However if running in a batch mode, I got RuntimeException:

public BatchRestResult recordBatch(RestAPI restApi) {
        BatchRestResult result = new BatchRestResult();
        RestNode userNode = restApi.getOrCreateNode(restApi.index().forNodes("user-id"),
            "user-id", user.getUserId(), null);

Spatial headache

Hi I deploy on an 1.9.1 neo4j server on ubuntu x64 13.04 with latest server plugin

neo4j-spatial-0.11-neo4j-1.9-server-plugin.zip

I put data with parameters both lat/lon equal to 5

and I do a query within distance with x=y=5 and radius 10

The snippet of creation of index

Index<Node> spatialindex;

 if(!index.existsForNodes("layer1"))
        {
            spatialindex = index.forNodes("layer1",SpatialIndexProvider.SIMPLE_POINT_CONFIG);            

        }
        else
        {
            spatialindex=index.forNodes("layer1");
        }

The snippet of addition

Node v = this.bgr.gds.createNode(); //creation
v.setProperty("lat", pkg.latitude);
v.setProperty("lon", pkg.longitude);
this.spatialindex.add(v,"dummy","value");

The snippet for searching

public Iterator<Node> queryPackagesSpatial(BiopolisSpatialQuery sq)
    {
        HashMap<String, Object> params = new HashMap<String, Object>();
        params.put(LayerNodeIndex.POINT_PARAMETER, new Double[]{sq.longitude,sq.latitude} );
        params.put(LayerNodeIndex.DISTANCE_IN_KM_PARAMETER, sq.radius);
        return this.bgr.pkg_mgmnt.spatialindex.query(LayerNodeIndex.WITHIN_DISTANCE_QUERY,params);
    }

It returns nothing. The snippets work on the client side

Neo4j graphDatabaseService blows up on context initialization if remote DB is down

When the Neo4j config is initialzed, and the remote DB is not running, the server will not start ..

<neo4j:config graphDatabaseService="graphDatabaseService" />
<bean id="graphDatabaseService class="org.springframework.data.neo4j.rest.SpringRestGraphDatabase">

is there a way to gracefully stop or halt it's creation when the server isn't running ?

This is a module in a much larger Application & I can't not start the app b/c Neo4j has stopped running ..

Unique Factory NPE in batch transaction

The example in the Neo4j docs won't work due to NPE:
http://docs.neo4j.org/chunked/milestone/transactions-unique-nodes.html

public Node getOrCreateUserWithUniqueFactory(String username, GraphDatabaseService graphDb ){    
    UniqueFactory<Node> factory = new UniqueFactory.UniqueNodeFactory(     graphDb, "users" )    {        
        @Override        
        protected void initialize( Node created, Map<String, Object> properties )        {  
    created.setProperty( "name", properties.get( "name" ) );        
        }    
    };     
    return factory.getOrCreate( "name", username );
}

The issue is at the factory.getOrCreate throws a NPE if Batch Transactions are enabled:
Exception in thread "main" java.lang.NullPointerException
at org.neo4j.rest.graphdb.index.SimpleIndexHits.getSingle(SimpleIndexHits.java:67)
at org.neo4j.rest.graphdb.index.SimpleIndexHits.getSingle(SimpleIndexHits.java:37)
at org.neo4j.graphdb.index.UniqueFactory.getOrCreate(UniqueFactory.java:197)

The problem is due to I think:

    public T getSingle() {
        Iterator<Object> it = hits.iterator();
        return it.hasNext() ? transform(it.next()) : null;
    }

"hits" is null causing the error.

2.0.2 release

@jexp is it possible to get a 2.0.2 release or 2.0.2-SNAPSHOT at http://m2.neo4j.org/content/repositories/snapshots/?

Unit testing class not packaged?

Hi,

I'm trying to figure out how to do unit tests with this rest-interface. As I can see in the tests of the project, you are using RestTestBase in the tests. Is that what I am looking for? If yes, why is it not packaged?

The other option would be to start a new local neo4j rest server on every test-run. This seems to be a bit overkill to me.

How is it meant to be done?

Thank you!

Dependency?

I added the dependency for my Maven project using the IntelliJ IDE like:

org.neo4j neo4j-rest-graphdb 1.8.M07

But I get the error:

Dependeny "org.neo4j:neo4j:neo4j-rest-graphdb:1.8.M07" not found more.... (CTRL+F1)

Rest Query Socket timeout control

org.neo4j.rest.graphdb.query.RestCypherQueryEngine.query()

When calling this method it would be useful to be able to control the timeout of the underlying socket. The current read timeout appears to be 30 seconds by default.

Provide a release which is compatible with Neo4j 2.0.0-RC1

There's currently no release available which works with Neo4j 2.0.0-RC1.

M06 has a problem retrieving the labels of a node:

java.lang.AbstractMethodError: org.neo4j.rest.graphdb.entity.RestNode.getLabels()Ljava/lang/Iterable;

Cannot query Lucene ":" using REST GraphDb

This works:

final QueryResult<Map<String, Object>> rows = cypher.query("START n=node:berbatikPerson('*:*') RETURN id(n) AS nodeId LIMIT 100", new HashMap<String, Object>());

While a direct Lucene query won't work :

graphDb.index().forNodes("berbatik").query("*:*")

UnsupportedOperationException - RestRelationshipIndex.query

RelationShipIndex not implemented.

RelationshipIndex idx = index.forRelationships("my_rels");
Relationship rel = idx.query("name:myname AND age:30", node1, node2).getSingle();

2.0.1 conflict with neo4j-kernel's package version of org.neo4j.helpers.collection.WrappingResourceIterator

I'm getting

java.lang.IllegalAccessError: org/neo4j/helpers/collection/WrappingResourceIterator

in a project with neo4j 2.0.1.
It looks like there is a version of org.neo4j.helpers.collection.WrappingResourceIterator in neo4j-kernel.jar which is package protected https://github.com/neo4j/neo4j/blob/master/community/kernel/src/main/java/org/neo4j/helpers/collection/WrappingResourceIterator.java

The kernel version gets picked up first and cause the error.
Not sure which version is the original and what's the reason for the duplication?

Add OSGi headers

Can OSGi manifest headers be added? This can easily be done by the Maven Bnd Plugin: http://felix.apache.org/site/apache-felix-maven-bundle-plugin-bnd.html

Alternatively I would be happy to do this for you if I can get a list of packages which should be exported. That's basically all packages that someone will reference when using this library.

Create Unique - NullPointerException

When I run this query in the Neo4j webadmin it runs perfectly:

start a = node(0) 
create unique a-[:Rel]->(b{key:'prop'})

However, when I use the above query like this:

GraphDatabaseService graphDb = new RestGraphDatabase("http://localhost:7474/db/data");

String query = "start a = node(0) "+
    "create unique a-[:Rel]->(b{key:'prop'})";  

ExecutionEngine engine = new ExecutionEngine( graphDb );        
engine.execute(query);

It results in a NullPointerException

Provides a version for 2.0.0 server

It would be great to have an official version for the new 2.0.0 Neo4J release !
Thank for your great work :-)

NullPointerException in ExecutionEngine on startup

Upon startup when using RestGraphDatabase as the GraphDatabaseService the following query is executed via the neo4j-cypher library:

MATCH (ref:ReferenceNode {name:{name}}) RETURN ref;

Which results in a NullPointerException. The reason why is as follows.

Within the ExecutionEngine at line 75 we have:

val statement = txBridge.instance()

The txBridge is null which causes the NPE. txBridge is defined on line 112 as:

private val txBridge = graph.asInstanceOf[GraphDatabaseAPI]
    .getDependencyResolver
    .resolveDependency(classOf[ThreadToStatementContextBridge])

The call to getDependencyResolver is causing the issue. In v2.0.0 of RestGraphDatabase at line 115:

@Override
public DependencyResolver getDependencyResolver() {
return new DependencyResolver.Adapter() {
    @Override
    public <T> T resolveDependency(Class<T> type, SelectionStrategy selector) throws IllegalArgumentException {
    if (TransactionManager.class.isAssignableFrom(type)) return (T)getTxManager();
    return null;
    }
};
}

The passed in type of ThreadToStatementContextBridge results in null being returned which manifests as the NPE in the ExecutionEngine.

In the latest version of RestGraphDatabase the getDependencyResolver has now been reomved which now results in:

Caused by: java.lang.UnsupportedOperationException
    at org.neo4j.rest.graphdb.AbstractRemoteDatabase.getDependencyResolver(AbstractRemoteDatabase.java:148)

Support Neo4j 1.9

Neo4j has hit it's 4th milestone now, but we still have no usable java rest api for it.

QueryResult is not closing itself.

Problem issues are documented here:

http://stackoverflow.com/questions/16148190/neo4j-queryresult-wont-exit

Currently I have this class. When I remove QueryResult it runs the main method and completes on its own. When I add QueryResult I need to manually kill the run.

public class TestConnect {
public static void main(String[] args) {
System.out.println("starting test");
final RestAPI api = new RestAPIFacade("http://localhost:7474/db/data");
System.out.println("API created");
final RestCypherQueryEngine engine = new RestCypherQueryEngine(api);
System.out.println("engine created");
QueryResult<Map<String,Object>> result = engine.query("start n=node({id}) return n;", map("id",0));
}
}

lack of Documentation

I have a hard time trying to use the java-rest-bindings. There is no real API documentation, and in general I only can find how to make "raw" REST requests. If there is no documentation/tutorial at all, I'll expect at least meaningful javadocs. For example:
new RestCypherQueryEngine(RestApi, ResultConverter).
It starts with the Question "What Is a Result Converter, for what do I need it, And what happens if I use the other Constructor...". If you have an instance of it and want to call its 'query' Method, WHAT the hell is the Map<String, Object> supposed to do?
No documentation/JavaDoc at all! How do you expect developers to use this java-rest-binding library? By trial and error, or not at all?
If I purchase an Neo4jEnterprise licence will I get documentation/support for this java-rest-binding API?

Cannot call batchRestApi.getNodeById() inside BatchCallback

This won't work:

graphDb.getRestAPI().executeBatch(new BatchCallback<Void>() {
    @Override
    public Void recordBatch(RestAPI batchRestApi) {
        Node node = batchRestApi.getNodeById(nodeId);
        for (Relationship rel : node.getRelationships()) {
            rel.delete();
        }
        node.delete();
        return null;
    }
});

The workaround is: (for this specific case only)

graphDb.getRestAPI().executeBatch(new BatchCallback<Void>() {
    @Override
    public Void recordBatch(RestAPI batchRestApi) {
        batchRestApi.deleteEntity(new RestEntity("/node/" + nodeId, batchRestApi));
        return null;
    }
});

NullPointerException in ExecutionEngine

Hi, I'm developing a Maven plugin and I'm running an issue whenever I try to execute following Cypher query against a remote graph database (v2.1.2):

MATCH (changelog:__LiquigraphChangelog)<-[exec:EXECUTED_WITHIN_CHANGELOG]-(changeset:__LiquigraphChangeset)
RETURN changeset
ORDER BY exec.order ASC

Here is the Java code:

ExecutionEngine engine = new ExecutionEngine(graphDatabase);
try (Transaction transaction = graphDatabase.beginTx()) {
    for (Map<String, Object> columns : engine.execute(QUERY_ABOVE)) { // line 26
        Node node = (Node) columns.get("changeset");
        changesets.add(changeset(node));
    }
    transaction.success();
}

This is the stack I get from Neo4j jar (2.0.0 to 2.0.4):

    at com.liquigraph.core.writer.ChangelogReader.read(ChangelogReader.java:24)

I guess I'm doing something wrong, but I don't know what.

Btw, I'm using neo4j-rest-graphdb in 2.0.1 version.
Interestingly, the NPE moved from query execution in 2.0.x to the ExecutionEngine instantiation in 2.1.x.

Could the latter be due to an incompatibility between rest-graph-db and neo4j v. 2.1.x ?
I'll dig deeper into the issue today and keep you updated.

Handling of cypher results with nested collections/maps with nodes and relationships

Executing Rest API throws a generic RuntimeException - Need more details

When the result of an operation is neither OK or CREATED, a plain RuntimeException with user inputs is thrown - as opposed to RequestResult's details:

if (result.statusIs(Response.Status.CREATED) || result.statusIs(Response.Status.OK)) {
return (RestRelationship)createExtractor().convertFromRepresentation(result);
}
throw new RuntimeException(String.format("Error retrieving or creating relationship for key %s and value %s with index %s", key, value, index.getIndexName()));

Propose to add client response and other details to runtime exception so that rest api java users can figure out whats going on.

"RestGraphDatabase" can not work with tinkerpop blueprints "Neo4jGraph"

hi, all, I am recently using tinkerpop blueprints stack as RDF triple store engine, and i try java-rest-binding api like this:

GraphDatabaseService ds = new RestGraphDatabase("http://localhost:7474/db/data");
Neo4jGraph graph = new Neo4jGraph(ds); //blueprints.impls.neo4j.Neo4jGraph

pop up a exception:
Exception in thread "main" java.lang.ClassCastException: org.neo4j.rest.graphdb.RestGraphDatabase cannot be cast to org.neo4j.kernel.InternalAbstractGraphDatabase

it seems "RestGraphDatabase" is not a subclass of "InternalAbstractGraphDatabase", is there any chance that i can work around this exception , so that i can reuse the whole blueprints stack for rdf sail processing ~

Property URLs not sanity checked

If I want to add a property named "Hello World" to a node I get an exception:
Caused by: java.net.URISyntaxException: Illegal character in path at index 55: http://localhost:7474/db/data/node/3/properties/Hello World

Which makes sense since the white space is invalid. The issue is that the embedded interface does allow for such property names.

Unable to add label using Neo4j Rest API - Error reading as JSON ''

The neo4j rest api throws runtime exception (error reading as JSON '') when trying to add a label.

My current set up

org.neo4j neo4j-rest-graphdb 2.0.0 org.neo4j neo4j 2.0.0 org.neo4j.app neo4j-server 2.0.0 Code that tries to create a new node and add a property and label. The runtime exception is thrown when we try to add the label. The rollback is working fine though. It appears that the API is trying to get details for the resource that is not yet created and trying to parse the response.

try ( Transaction tx = db.beginTx() ) {
//create new user
Node userNode = db.createNode();
userNode.setProperty( "id", id );
userNode.addLabel(DynamicLabel.label("GuestUser")); //throws runtime exception
tx.success();
}

Create node with labels

It is possible to create a node with labels directly? Right now I am implementing a cypher query but would be nice if the create method from RestApi would support it (branch 2.0-labels-...)
The reason is to be able to use constraints. If we first create the node and then the label a constraint will not "constraint" until the node has not been created. As a result we have a node without label that has ignored a constraint.

Tutorial/startup docs for java-rest-bindings

Can someone provide a heads for java-rest-binding with some demo code?

cannot process big batch > 8k

Hello, I found the following bug in your library.
https://github.com/neo4j/java-rest-binding/blob/1.8.RC1/src/main/java/org/neo4j/rest/graphdb/ExecutingRestRequest.java
private InputStream toInputStream(Object data) {
try {
if (data instanceof InputStream) return (InputStream) data;
PipedInputStream inputStream = new PipedInputStream(8 * 1024);
PipedOutputStream outputStream = new PipedOutputStream(inputStream);
StreamJsonHelper.writeJsonTo(data, outputStream);
return inputStream;
} catch (IOException e) {
throw new RuntimeException("Error writing "+data+" to stream",e);
}
}
Here you have buffer of 8kB: new PipedInputStream(8 * 1024);
But when I have big json request s your library hangs on: the following code:

https://github.com/neo4j/java-rest-binding/blob/1.8.RC1/src/main/java/org/neo4j/rest/graphdb/util/StreamJsonHelper.java
public static void writeJsonTo( Object data , OutputStream stream) {
try {
JsonGenerator generator = OBJECT_MAPPER.getJsonFactory()
.createJsonGenerator(stream);
OBJECT_MAPPER.writeValue(generator, data);
stream.close();
} catch ( IOException e ) {
throw new RuntimeException( e );
}
}

Here the code block on this line: OBJECT_MAPPER.writeValue(generator, data);
The problem actually is that when you try to write big data (more than 8kB) to the outputStream , then the code hangs.

Please provide the fix for this issue, because your library is not able to process big messages.

jar naming

Hi all,
did
git clone https://github.com/neo4j/java-rest-binding
mvn clean package
and got it completed successfully. Now I found the jar but it is named
neo4j-rest-graphdb-1.9.3-SNAPSHOT.jar

version should be named correctly.

getReferenceNode throws Error

We are trying to switch from running as an embedded DB to using a Neo4j server and hit a consistent problem. It's occurring frequently enough that there must be something obvious we are doing wrong. This error shows up lots of places, but this is the simplest example I have.

In a call to myRestGraphDb.getReferenceNode(), we get the following:

Exception in thread "main" java.lang.RuntimeException: Error reading as JSON ''

This error also occurs when we call node.getSingleRelationship and there does not exist a relationship. The embedded code returns null. The rest API throws the same exceptions.

We are using:

 Neoj4 1.8.M07 for both embedded and on the server   
 jackson-mapper-asl 1.8.5
 java 1.6
 server is running on Amazon AWS linux, clients are mac w/ OS X and PC w/ linux (same error on both clients)

Any thoughts, suggestions or solutions would be appreciated.

Warm regards,
Wallace

Workaround: Use LIMIT

Labels are not accessible immediately on Nodes returned from a Cypher query

I have found that Node.hasLabel(..) does not always work where Node is the return from a Cypher query. Adding a short delay into the client code resolves this problem. A test case follows.

The cause seems to be this;
Label data is not acquired at the same time as the return of a Node object in the Cypher query (why not? this may be the origin of the defect). However, the code is programmed to consider if the Node.labels data is up to date and so the consequence of waiting a short time is that the implementation refreshes the label data. This can be seen in Node.hasLabel() -> RestNode.updateLabels() -> RestEntity.hasToUpdateProperties() -> restApi.hasToUpdate(). This forces a refresh after ~1 second I think.

I am using my own build of the API based on the branch "20".

could you please uograde the jersey-client version

Now java-rest-binding uses the jersey-client version is 1.4 ,the latest jersey-client version is 2.7 . The jersey-client dependency is too old ,it will casue more conflict with other libraries ,could you please uograde the jersey-client version ?

It happens randomly in a few cases, so I don't think it's due to my code.

Any idea?

Cannot create Relationship from/to non-batched Nodes in BatchCallback

While this works:

    TestBatchResult r = this.restAPI.executeBatch(new BatchCallback<TestBatchResult>() {
        @Override
        public TestBatchResult recordBatch(RestAPI batchRestApi) {
            TestBatchResult result=new TestBatchResult();
            result.n1 = batchRestApi.createNode(map("name", "newnode1"));
            result.n2 = batchRestApi.createNode(map("name", "newnode2"));
            result.rel = batchRestApi.createRelationship(result.n1, result.n2, Type.TEST, map("name", "rel") );
            result.allRelationships = result.n1.getRelationships();
            return result;
        }
    });

This won't:

    final Node node1 = graphDb.getNodeById(1);
    final Node node2 = graphDb.getNodeById(2);
    TestBatchResult r = this.restAPI.executeBatch(new BatchCallback<TestBatchResult>() {
        @Override
        public TestBatchResult recordBatch(RestAPI batchRestApi) {
            TestBatchResult result=new TestBatchResult();
            result.rel = batchRestApi.createRelationship(node1, node2, Type.TEST, map("name", "rel") );
            return result;
        }
    });

RestNode.getProperty(...) returns String while Node.getProperty returns byte[]

We are facing issue for the below scenario.

We have a requirement where we need to store java.util.Set in a graph node (where Rule is a complex business rule object). Since, node.setProperty(..., ...) doesn't allow complex objects, we have serialized the above Set and converted it to byte array and stored it as node.setProperty("rules",serialize("rules")) (2nd argument is a bytearray)

2.The above code works properly when we use EmbeddedGraphDatabase class. In this case, node.getProperty ("rules") returns us a byte array. We get the bytearray and deserialize it to retrieve our Set . (This works fine)

But, when we use RestGraphDatabase class, node.getProperty("rules") returns us a String representation instead of a byte array. Is this expected ? Next, we tried to convert the String to byte array using String.getBytes()
But, when we pass the bytearray to an ObjectInputStream to deserialize, we get "StreamCorruptedException: Invalid Stream Header".

We are looking for different alternatives to fix this . Need your help.

Sample project: https://github.com/ceefour/likebox/zipball/neo4j-rest-blueprint

Code to create index :

protected Index<Vertex> getIndex(String kind) {
    String indexName = prefix + kind;
    log.debug("Get vertex index {}", indexName);
    try {
        return g.getIndex(indexName, Vertex.class);
    } catch (Exception e) {
        log.info("Creating vertex index " + indexName, e);
        return g.createManualIndex(indexName, Vertex.class);
    }
}

Issue is still reproducible on Neo4j 1.7 via RestGraphDb and Blueprints 1.2.

Workaround : Go to webadmin Gremlin console then create the indexes via Gremlin/Blueprints :

g.createManualIndex('berbatikPerson', Vertex.class)
g.createManualIndex('berbatikProduct', Vertex.class)

A non-Blueprints index is not usable, because plain index have parameters of only:

{"type":"exact"}

while a Blueprints index has parameters of:

{"_blueprints:type":"MANUAL", "type":"exact"}
