Hi I just installed jBPM 4.0.CR1 following the user manual step by step. I added the file jpdl-4.0.xsd to Eclipse (Preferences --> XML Catalog) and still lots of problems appear after compiling the examples that come with jBPM. It seems that jpdl-4.0.xsd lacks some definitions. For example: Description Resource Path Location Type cvc-complex-type.2.4.a: Invalid content was found starting with element 'custom'. One of '{"http://jbpm.org/4.0/jpdl":swimlane, "http://jbpm.org/4.0/jpdl":on, "http://jbpm.org/4.0/jpdl":timer, "http://jbpm.org/4.0/jpdl":start, "http://jbpm.org/4.0/jpdl":end, "http://jbpm.org/4.0/jpdl":end-cancel, "http://jbpm.org/4.0/jpdl":end-error, "http://jbpm.org/4.0/jpdl":state, "http://jbpm.org/4.0/jpdl":decision, "http://jbpm.org/4.0/jpdl":fork, "http://jbpm.org/4.0/jpdl":join, "http://jbpm.org/4.0/jpdl":script, "http://jbpm.org/4.0/jpdl":hql, "http://jbpm.org/4.0/jpdl":sql, "http://jbpm.org/4.0/jpdl":java, "http://jbpm.org/4.0/jpdl":task, "http://jbpm.org/4.0/jpdl":sub-process}' is expected. process.jpdl.xml examples/src/org/jbpm/examples/custom line 10 XML Problem or this one: Description Resource Path Location Type cvc-complex-type.3.2.2: Attribute 'continue' is not allowed to appear in element 'java'. process.jpdl.xml examples/src/org/jbpm/examples/async/activity line 20 XML Problem View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4237379#...
