Designer: host/port expectations seems to be hardcoded

Based on mailing list thread, attempting to configure JBPM Designer to work in an environment that is not localhost and/or not standard port 8080 will fail ("connection refused" has been seen).

even though changes to the /designer.war/profiles/jbpm.xml file occur for configuring Guvnor interaction, there is still other code that connects to designer itself via localhost:8080 that needs to be updated.

Example w/ jboss 5.1:
Modify the -b name/ip binding on startup, modify the configuration to change default ports:
"run.sh -b <myrealIPandnotlocalhost>"

edit portoffset for default bindings: /server/<servername>/conf/bindingservice.beans/META-INF/bindings-jboss-beans.xml
=================

<!-- The ports-default bindings are obtained by taking the base bindings and adding 0 to each port value -->
<bean name="PortsDefaultBindings" class="org.jboss.services.binding.impl.ServiceBindingSet">
<constructor>
<!-- The name of the set -->
<parameter>ports-default</parameter>
<!-- Default host name -->
<parameter>${jboss.bind.address}</parameter>
<!-- The port offset -->
<parameter>40000</parameter>
<!-- Set of bindings to which the "offset by X" approach can't be applied -->
<parameter><null/></parameter>
</constructor>
</bean>
