Hello,
I'm using the great new release of jbpm (5.2) on the great jboss7 (thanks guys for the excellent job) on a remote address (not localhost) on a custom port (not 8080) and i've noticed that in order to use the png and pdf functions of web designer one might need to add three jars in designer.war (in WEB-INF/lib). The jars are,
commons-logging-1.0.4.jar
xml-apis-1.3.04.jar
xercesImpl-2.9.1.jar
and they can be found in drools-guvnor.war
Restarting the server, after redeployment, is required.
