I thought are sharing this information as one would run into a problems running jbpm console from a remote box.
There is a file called jbpm.console.properties that includes the host information and it is included in jbpm-gwt-core-5.0.0.jar.
The contents of this file are as follows:
jbpm.console.server.host=localhost
jbpm.console.server.port=8080
jbpm.console.task.service.host=127.0.0.1
jbpm.console.task.service.port=9123
You need to change the host value, i.e provide your hostname instead of using localhost and bundle it jbpm-gwt-core-5.0.0.jar.
