Hi All,

I am trying to connect Guvnor with the jbpm console. It is almost working, but now I am facing one problem.

I have my processes, rules and process images in a package "org.test..".
When go to the process part of the console, I can see the deployed processes and create instances. However, I cannot see the process image (it says there is no image).

Checking the logs I find that, first, the definitions point to the right package:
INFO  20-06 13:18:14,021 (NilAuthenticator.java:authenticate:35) All users are guests.INFO  20-06 13:18:14,021 (RepositoryServlet.java:allowUser:114) admin authenticated for rest apiINFO  20-06 13:18:14,022 (PackageDeploymentServlet.java:execute:141) PackageName: org.testINFO  20-06 13:18:14,022 (PackageDeploymentServlet.java:execute:142) PackageVersion: LATESTINFO  20-06 13:18:14,022 (PackageDeploymentServlet.java:execute:143) PackageIsLatest: trueINFO  20-06 13:18:14,022 (PackageDeploymentServlet.java:execute:144) PackageIsSource: false[2011-06-20 13:18:14,300:debug] KnowledgeAgent obtaining pkg resource=[UrlResource path=' http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/org.test/LATEST http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/org.test/LATEST']
 http://community.jboss.org/message/611043#611043#611043/2011-06-20 13:18:14,300:debug Connecting Console with Guvnor KnowledgeAgent mapping resource=[UrlResource path=' http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/org.test/LATEST http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/org.test/LATEST'] to KnowledgeDefinition=[Rule name=Exceeds, agendaGroup=MAIN, salience=0, no-loop=false]


However, the log continues and I can see many exceptions like this:
java.io.IOException: Server returned HTTP response code: 500 for URL:  http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/defaultPackage/LATEST/Milestone_completed-image.png http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/defaultPackage/LATEST/Milestone_completed-image.png

          at org.jbpm.integration.console.graph.GraphViewerPluginImpl.getDiagramURL(GraphViewerPluginImpl.java:255)



If I check the following code:
org.jbpm.integration.console.graph.GraphViewerPluginImpl:
public URL getDiagramURL(String id) {
...
sb.append(" http:// http://");
                              sb.append(properties.get("jbpm.console.server.host"));
                              sb.append(":").append(new Integer(properties.getProperty("jbpm.console.server.port")));
*                              sb.append("/drools-guvnor/org.drools.guvnor.Guvnor/package/defaultPackage/LATEST/");*
                              sb.append(URLEncoder.encode(id, "UTF-8"));
                              sb.append("-image.png");
}

It there a way to indicate the console to use not the default packages for png and also drl (AbstractFormDispatcher has the same logic)

Thanks

Demian
