you would need to create copies of following:
- jbpm-gwt-console-server.war
- make sure you edit jboss-web.xml inside to provide unique context root
- edit persistence.xml if needed (data source)
- jbpm-gwt-console.war (make sure you edit jboss-web.xml inside to provide unique context root)
- define data sources if needed
if human task needs to be duplicated follow steps defines for console-server
