Runtime error on Java(TM) SE Embedded Runtime Environment about jsondb-core HOT 5 OPEN

Just by looking at your Exception Stacktrace i think Java(TM) SE Embedded Runtime Environment does not have the "java.nio.file." package. I can fix this and create a version of JsonDB that does not uses classes from this package "java.nio.file." at all.

The other issue of "annotations" support not present in the Java(TM) SE Embedded Runtime Environment " is a bit of trouble, I will study this in a day or 2 when i get some time and try to see if i can find a decent workaround.

Thank you for you fast reply @FarooqKhan.

It would be really nice if we could make use of your package. It`s more straightforward and "cleaner" than the old "mapdb" option.

Hi PanzerHabba,

The initial warnings you see about "annotations, java.nio.file.Path" are a issue but it will not be a problem unless you try to Add a EventListener to the watch for direct changes to the db files using other filesystem utilities. This is a usecase that very few people would want to use.

However the issue of the class "ClassNotFoundException: java.beans.PropertyDescriptor" is a more troubles some. JsonDB uses Apache JxPath library very heavily for all the XPATH support. This JxPath library depends on the "java.beans" package. This is a problem that Android users face often becuase Dalvik does not have the "java.beans" package

I am surprised that Java SE Embedded does not have this package. If it is indeed true that Java SE Embedded does not have this package then you can try a workaround to your problem you will need to obtain the JxPath source code replace all usage of java.beans.* with "com.googlecode.openbeans" recompile and use this custom JxPath library

This is certainly a lot of work you probably wont want to do this.

I will keep looking for ways to solve this, and keep this open.

For now unfortunately i dont have a better solution.

Thanks

Hi FarooqKhan,

I didn't have any problem running a JsonDB simple code on this environment:

• Java(TM) SE Embedded Runtime Environment (build 1.8.0_131-b11, headless)
• Linux 4.9.39-2-ARCH #1 SMP Wed Jul 26 01:23:45 UTC 2017 armv7l GNU/Linux

I did a simple project saving data and making an XPath query.

Hope this info could help you.

Regards.
