Restful web service with jbpm process fails

miliks1975 Apr 27, 2015 10:16 AM

Dear jbpm expert,

i get stucked with a problem.

I have created a simple restful web service wich is starting the jbpm process on arriving a message. On Jboss 7 it was wirking fine, but i need to deploy this app on WildFly.

First i get the problem with deployment but it was resolved adding the jboos-full.xml to the META-INF folder.

But on runtimewhen it comes to the process call inside the web service i'm getting an error:

13:01:34,665 ERROR [io.undertow.request] (default task-12) UT005023: Exception handling request to /JAXRS-RESTEasy-0.0.1-SNAPSHOT/rest/hello/temp: org.jboss.resteasy.spi.UnhandledException: java.lang.NullPointerException

Please help me!!!!

Thanks in advance.

If you need further details about the project please let me know.

P.S.: I'm using the Eclipse Kepler for development. I was trying to deploy it via Eclipse and directly on WildFly but with the same results... deployment is successfull but on the process call always this error.
