Hi all,
*I successfully starts the +Human Task Service of jBPM5.1+ in JBoss by modifing the Persistence.xml: :)*

By these modifications and placing the necessary files, I able to start the human task service via JBoss :
*Now I want my +jbpm task+ run using this service as under:*
// load up the knowledge base
KnowledgeBase kbase = readKnowledgeBase();
StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
WSHumanTaskHandler objWSHuman= new WSHumanTaskHandler();
objWSHuman.setConnection("127.0.0.1", 9123);
ksession.getWorkItemManager().registerWorkItemHandler("Human Task",objWSHuman);
// start a new process instance
Map<String, Object> params = new HashMap<String, Object>();
params.put("employee", "rajan");
params.put("reason", "Yearly performance evaluation");
ksession.startProcess("com.sample.evaluation", params);
System.out.println("Thats itt..");
*But on the JBoss console it gives the following error*: :(

[JBoss Tools] - Jboss Maven Jsf Integration: Faces-config.xml Editor Problem

Dear all,
My problem is that I want to use Eclipse JSF Faces-config editor to draw navigation rules between xhtml page.
But with the use of Jboss Maven Jsf Integration it's seem impossible (see the file in attachment).
I have detected the problem :
The Jboss plugin adds in the file *org.eclipse.wst.common.component :*
* ...*
* <wb-resource deploy-path="/" source-path="/target/m2e-wtp/web-resources"/>*
<wb-resource deploy-path="/" source-path="/src/main/webapp"/> *...*
And the Eclipse faces-config editor seems to load the first wb-resource with the attribute "source-path" and ignoring the next one.
If you inverse these two ligns. the faces editors works (we can chose Page to define navigation rules).
But when an maven update project configuration is launch, the plugin writes *<wb-resource deploy-path="/" source-path="/target/m2e-wtp/web-resources"/>* always before <wb-resource deploy-path="/" source-path="/src/main/webapp"/>.
Is it a bug of Jboss Tools or of the Editor?
Thanks,
Yoel
