I am using Neo4J community edition 2.3.0 on windows OS 10. Everything works well until I changed the configuration at neo4j-server.properties files as:
org.neo4j.server.thirdparty_jaxrs_classes=org.neo4j.examples.server.unmanaged=/examples/unmanaged
The error at server startup is:
Starting Neo4j failed: org.neo4j.server.web.NeoServletContainer-5b85e832@73766070==org.neo4j.server.web.NeoServletContainer,-1,false
If I disable this change then server starts very well. I am trying to run the HelloWorld example for the unmanaged extension as given with the Neo4J tutorial and follow all the instructions.
The Java compiler used to build the Jar is 1.7 and I am working on STS tool.
An early response would be helpful.
The console log is as following

The problem is that the .jar you are using does not have the required .jars
Try exporting the your jar as an executable jar (I did it from Eclipse) and check the option "Package required libraries into generated JAR"
