I'm not sure if there's a better way, but to enable content assist for the process definitions in the Graphical Process Designer: - Eclipse, Preferences - Web and XML - XML catalog - User specified entries, click Add - URI: http://docs.jboss.org/jbpm/xsd/jpdl-3.2.xsd - Key Type: Namespace Name - Key:urn:jbpm.org:jpdl-3.2 This enables content assist for: <?xml version="1.0" encoding="UTF-8"?> | <process-definition name="my-process" xmlns="urn:jbpm.org:jpdl-3.2"> | : | </process-definition> Of course, without making any chances to Eclipse preferences, or when using other tools, one could also explicitly specify the location: <?xml version="1.0" encoding="UTF-8"?> | <process-definition name="my-process" xmlns="urn:jbpm.org:jpdl-3.2" | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" | xsi:schemaLocation= | "urn:jbpm.org:jpdl-3.2 http://docs.jboss.org/jbpm/xsd/jpdl-3.2.xsd"> | : | </process-definition> Note that in both cases using xmlns="urn:jbpm.org:jpdl-3.2" will enable runtime XML validation, under some conditions, as described in 16.4.1. Validation in the documentation. Arjan. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4032693#...
