Thanks for your response, Kris.
Now I can access drools-guvnor in jBPM.
But I can't access web-based Oryx, eventually I find that "ant install.demo" doesn't install "Oryx Designer" into JBOSS AS.
So can you give me an URL of "Oryx Designer"?
By the way, I have copied evaluation.bpmn into jbpm-installer\jboss-4.2.3.GA\server\default\deploy, and I have found it is deployed into jbpm-installer\jboss-4.2.3.GA\server\default\tmp\deploy as tmp60197Evaluation.bpmn, but I can't see it in http://localhost:8080/gwt-console-server/rs/server/resources.
When I want to see evaluation process in http://localhost:8080/jbpm-console/app.html by clicking on"processes"==> "process overview", it shows the following error:
==========================================================
HTTP 500:
Etat HTTP 500 -
type Rapport d'exception
message
description Le serveur a rencontré une erreur interne () qui l'a empêché de satisfaire la requête.
exception
org.jboss.resteasy.spi.UnhandledException: java.lang.RuntimeException: Could not initialize stateful knowledge session: java.lang.reflect.InvocationTargetException
====================================================
And when I click on "processes"==>"execution history", it shows the following error:
====================================================
HTTP 500:
Etat HTTP 500 -
type Rapport d'exception
message
description Le serveur a rencontré une erreur interne () qui l'a empêché de satisfaire la requête.

====================================================
Can you give me some explanation ?
