[rules-users] errors of deploying Guvnor 5.2.0 to JBoss 7.0

[Jervis Liu]

Notice this line:

org.jboss.as.jaxrs.deployment.JaxrsScanningProcessor.checkDeclaredApplicationClassAsServlet(JaxrsScanningProcessor.java:310)

So the problem is JaxrsScanningProcessor can not load 
CXFNonSpringServlet. This is because AS 7 JAX-RS is configured to use 
RESTEasy by default.  Two options I can think of:

1. Modify modules/org/jboss/as/jaxrs/main/module.xml to add dependencies 
on CXF modules so that JaxrsScanningProcessor can use CXF as JAX-RS 
stack as an alternative.

To go with this approach, you will have to install CXF in AS 7  by 
yourself, then define cxf modules similar to what 
org/jboss/resteasy/resteasy-jaxrs/main/module.xml does.

2. Disable JaxrsScanningProcessor so that Guvnor can use CXF to load 
JAX-RS resources using CXF's own way.

This approach is what we did in AS 6. We configured CXF to use its own 
non-standard way to load JAX-RS resources other than using the standard 
javax.ws.rs.core.Application. But for some unknown reasons, this 
approach seems not working for AS 7 anymore.

I can take a further look once I have time.

Cheers,
Jervis
