Play 2.4.x about anormcypher HOT 12 CLOSED

I got the same issue with Play 2.4.1, other than this exception, there is another one:
java.lang.NoClassDefFoundError: Could not initialize class dispatch.Http$

The way to use Ws changes between 2.3.x and 2.4.x.

https://www.playframework.com/documentation/2.3.x/ScalaWS
https://www.playframework.com/documentation/2.4.x/ScalaWS

I guess this is the reason why.

any solutions?

Using Ws directly, it works perfectly

from anormcypher.

Play 2.4 uses async-http-client 1.9. AnormCypher also has a dependency on async-http-client via the dispatch wrapper library, and that version is 1.8. And the upgrade has some breaking changes. Hence the conflict.

You can temporarily use WS directly, as callicles suggested.

There is an experimental branch to return an Enumerator[CypherResultRow] in order to stream very large graph data sets. The underlying http client is Play's WS wrapper instead of dispatch. You are welcome to try it, but it would probably require you to write an adaptor, as the original Future[Stream[CypherResultRow]] api is not yet done. If that branch gets merged, we could switch from dispatch to Play WS and be more closely integrated with Play in the future.

Hi Kai-Chen, is there any ETA for the fix yet?

from anormcypher.

Not that I know of, Volkan. And I have to say: very sorry about that. I will ping Wes and see if we can get that done soon. Backward compatibility is super-important, but I don't know any coder that reguarly puts that on the top of his to-do list.

Changing the dependency from ning to play is not trivial, and it would probably end up spilling into the client interface with anormcypher. One solution would be to switch to PlayWS in the newer version, breaking the api before 0.6, and just leave it at that. Even if we decide to take that route, there are still architectural concerns like should we introduce a separate WS client layer (which really would just look very much like either Ning or PlayWS and would have to expose it somehow anyway), and should that be added as an implicit (like what we are doing now) or a required parameter. Another concern is that a standalone client should still be easy to write, i.e. without the need to explicitly configure too much stuff. So it's not just a tiny bug fix :) But I hope we can get that decided soon enough.

If you're using Play 2.4, update dispatch to "net.databinder.dispatch" %% "dispatch-core" % "0.11.3",, this should fix incompatibilities between the new Ning and dispatch libraries.

@flashingpumpkin that is so true!!! Thank you very much!

from anormcypher.

It doesn't look like there is a way to support both Play 2.3 and Play 2.4 with the same build of AnormCypher. So going forward, AnormCypher 0.7.0 will be the last version that can be used in Play 2.3. And AnormCypher 0.7.1 will be built with Play 2.4. Both will be released in about a week.

• Use AnormCypher 0.7.1 for Play 2.4
• Use AnormCypher 0.7.0 for Play 2.3

Perfect Kai-Chen. I will try it now. Thanks a lot!
