Hi,
the properties file is located in jbpm-gwt-core-5.1.0.Final.jar of jbpm-gwt-console-server.war. Also make sure to modify the ChangeSet.xml as well also located in jbpm-gwt-core-5.1.0.Final.jar. You will probably have to modify persistence.xml and hibernate.cfg.xml files located inside jars of this war i.e.
- jbpm-human-task-5.1.0.Final.jar and jbpm-bam-5.1.0.Final.jar as well as in the runtime used by the human task
- jbpm-gwt-console-server.war META-INF
- jbpm-gwt-console-server.war lib/jbpm-human-task-5.1.0.Final.jar META-INF
- jbpm-gwt-console-server.war lib/jbpm-bam-5.1.0.Final.jar META-INF
- jboss datasource i.e. modify testDS1-ds.xml
Although i would certainly advise you to migrate to jbpm5.2, where all settings are centralized along with many other features and fixes
