We have a working JBPM5.4 setup in our dev pc. All works just fine.
Then, we deploy JBPM5.4 in 4 different servers, the guvnor repository on these 4 servers is imported from the guvnor repo on our dev pc.
The weird problem is, we can retrieve process image only on the 3rd server by calling this REST URL
the other three server does not return anything when we access that REST URL.
What could be the cause of this?
Been looking at the server.log and found this error
15:07:31,168 ERROR [org.jbpm.integration.console.graph.GraphViewerPluginImpl] (http--192.168.25.119-9080-69) Could not get process image from Guvnor: org.apache.commons.io.IOUtils.copy(Ljava/io/InputStream;Ljava/io/Writer;)V
Attached the server log, the server log is cleared and then I do regenerate the process image and then accesss the REST URL to get process image
It was caused by corrupt jar, just need to re copy the jar (commons-io) from the installer.
