I am experiencing a “classic” error. The ResourceConfig instance does not contain any root resource classes from HelloWorldResource.java
I followed the instructions for Unmanaged Extensions :
- Added JAR file in plugins directory
- Set org.neo4j.server.thirdparty_jaxrs_classes = org.neo4j.examples.server.unmanaged = / examples / unmanaged
And here is the code:
package org.neo4j.examples.server.unmanaged; import ... @Path( "/helloworld" ) public class HelloWorldResource { //private final GraphDatabaseService database; //public HelloWorldResource( @Context GraphDatabaseService database ) //{ // this.database = database; //} @GET @Produces( MediaType.TEXT_PLAIN ) @Path( "/{nodeId}" ) public Response hello( @PathParam( "nodeId" ) long nodeId ) { // Do stuff with the database return Response.status( Status.OK ).entity( ("Hello World, nodeId=" + nodeId).getBytes( Charset.forName("UTF-8") ) ).build(); } }
I am using Windows 8.1 and ENTERPRISE 2.2.0_M02, when I start bin\Neo4j.bat I get an error.
