I encountered the same problem. Have you found a solution?
I dont know about that particular tool/server constellation. I just tell you about my environment and hope it helps you.
When a process is deployed, the process definition file is committed into the guvnor repository (webdav). If that is also the case in your environment, the file should end up in the default package.
You can usually reach that over http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/webdav/ (Import it in your win explorer). My eclipse therefore has a guvnor connection. Maybe this connection is missing in your case?
Or the server is down?
Hope this brings you somehow closer.
Thank you for your reply. I was lucky to get it work last night.
I am using - SOA-P-5.1 + JBDS 4.0 on Window Platform
I did 2 things
1) Changed the Server Deployer from "/jbpm-console/upload" to "/gpd-deployer/upload"
2) Changed <attribute name="DownloadServerClasses">true</attribute> (from false to true)
[The usage of this attribute is written on SOA Getting Started Guide Section 2.4.5]
I figured the 2nd step after I read https://issues.jboss.org/browse/SOA-1586 mentioned about 'secured' and 'unsecured' profile
Hope this may help others.
