<div class="jive-rendered-content"><p>Hi</p><p><br/>I've tried installing JBPM console 5.2 (downloaded war) and 5.3 (compiled myself with maven) at separate times.  I am running in JBoss AS 7.0.2.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>In both cases I changed the login provider to be JAAS filesystem based/container managed.  I also changed the persistence to use MySQL through a JNDI datasource.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>If anyone has any ideas it would be much, much appreciated.  I just want to see my process in the web UI console.  Please <span> :) </span>.</p><h4>Dom4j Error</h4><p>In both versions I get:</p><p>Caused by: org.dom4j.DocumentException: org.dom4j.DocumentFactory cannot be cast to org.dom4j.DocumentFactory Nested exception: org.dom4j.DocumentFactory cannot be cast to org.dom4j.DocumentFactory</p><p>when deploying jbpm-gwt-console-server.  To remedy this, I removed both dom4j jars (1.6 and 1.6.1) from WEB-INF/lib in the jbpm-gwt-console-server.  This lets me get past deployment.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I can log in to JBPM console server with no errors.  I get an error in rendering the task pane, but that seems to go away after the first time it renders.  I would paste it here, but the error has not occurred since I set the process pane to be default on login.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><h4>Errors in Console Server Process Pane </h4><p>I navigate to the process pane, hit refresh, and in both versions (5.2 and 5.3) I get an error.</p><p style="min-height: 8pt;
