I am trying to add graphaware/neo4j/timetree to my project, but I am getting this error: org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.IllegalStateException: A RequestDispatcher could not be located for the default servlet 'default'

-rw-r--r-- 1 admin admin 13M Jan  1 10:11 graphaware-timetree-3.1.0.44.26.jar

I added this to my neo4j.conf: dbms.unmanaged_extension_classes=com.graphaware.server=/graphaware

The response from postman to POST http://localhost:7474/graphaware/timetree/now has a 500 status code with the error above:

I should have mentioned I am running neo4j community v3.1.0.

Hi @dangerginger

Unfortunately I'm unable to reproduce the issue :

Can you paste the stacktrace from neo4j.log and debug.log as well as a bash output of the ls command of the plugins directory to show permissions of the jar files. Thanks

Also, can you try with the Cypher procedure equivalent :

CALL ga.timetree.now({})

There is nothing in the debug.log.

Attempting the to call the Cypher procedure in the browser and on the cli neo4j-shell give the following error:

WARNING: There is no procedure with the name `ga.timetree.now` registered for this database instance. Please ensure you've spelled the procedure name correctly and that the procedure is properly deployed.

That seems to clear up the problem, but I am not sure how I installed it incorrectly.

Ok, very sorry to have taken your time. Somehow both of the files I placed in the plugin directory are exactly the same. I somehow screwed up copying them. I'm not sure what I did but it was easy to fix. I replaced the timetree jar file and it works just fine. I wish I would have figured this out in a less public forum lol.

No worries, glad it works now
