Using REST Remote API across deployments

[dosten]

Hello,

I am using the KIE REST Remote Java API from a JBoss SAR to hit jBPM in the standard KIE console war (version 6.1.0.Final) as described here.

However, when I try to start a process, the process does indeed start, but then I get the following exception:

07:50:04,240 FINER org.kie.services.client.serialization.jaxb.impl.JaxbCommandsResponse cannot be cast to org.kie.services.client.serialization.jaxb.impl.JaxbCommandsResponse: java.lang.ClassCastException: org.kie.services.client.serialization.jaxb.impl.JaxbCommandsResponse cannot be cast to org.kie.services.client.serialization.jaxb.impl.JaxbCommandsResponse

    at org.kie.services.client.api.command.AbstractRemoteCommandObject.executeRestCommand(AbstractRemoteCommandObject.java:406) [kie-services-client-6.1.0.Final.jar:6.1.0.Final]

    at org.kie.services.client.api.command.AbstractRemoteCommandObject.execute(AbstractRemoteCommandObject.java:120) [kie-services-client-6.1.0.Final.jar:6.1.0.Final]

    at org.drools.core.command.impl.CommandBasedStatefulKnowledgeSession.startProcess(CommandBasedStatefulKnowledgeSession.java:230) [drools-core-6.1.0.Final.jar:6.1.0.Final]

According to https://bugzilla.redhat.com/show_bug.cgi?id=1098972, it was fixed in v6.

Any ideas?

as described in bugzilla it was caused by additional jaxb-api jar that caused issues. So you might want to look at the packages and see if you have that jar and if so remove it.

I tried going down that path and never got it work.  There was always some class missing or conflicting.  I am using a different invocation method now but might get back to this issue later.
