To view the discussion, visit: http://community.jboss.org/message/610572#610572 -------------------------------------------------------------- Hi Esteban! thank you for your answer! I'm using jbpm5 and, reading the user guide, I thought that the solution for my problem was to use an embedded sub-process... but maybe I don't understand the difference between embedded and reusable sub-process! BTW I read your example and I tried to do the same, so: 1) I create a new .bpmn file with a Reusable Sub-Process node, with ProcessId parameter set to: com.sample.bpmn.hello (is the id of the process that I want to reuse); 2) I added the new resource to the kbuilder; Now: I should start the new process, but I didn't do because I wanted to test if something was wrong... infact!... java.lang.NullPointerException           at org.jbpm.bpmn2.xml.di.BPMNPlaneHandler.end(BPMNPlaneHandler.java:75)           at org.drools.xml.ExtensibleXmlParser.endElement(ExtensibleXmlParser.java:420)           at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.endElement(Unknown Source)           at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaValidator.endElement(Unknown Source)           at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanEndElement(Unknown Source)           at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl$FragmentContentDriver.next(Unknown Source)           at com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl.next(Unknown Source)           at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl.next(Unknown Source)           at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanDocument(Unknown Source)           at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(Unknown Source)           at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(Unknown Source)           at com.sun.org.apache.xerces.internal.parsers.XMLParser.parse(Unknown Source)           at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.parse(Unknown Source)           at com.sun.org.apache.xerces.internal.jaxp.SAXParserImpl$JAXPSAXParser.parse(Unknown Source)           at javax.xml.parsers.SAXParser.parse(Unknown Source)           at org.drools.xml.ExtensibleXmlParser.read(ExtensibleXmlParser.java:295)           at org.drools.xml.ExtensibleXmlParser.read(ExtensibleXmlParser.java:174)           at org.jbpm.compiler.xml.XmlProcessReader.read(XmlProcessReader.java:45)           at org.jbpm.compiler.ProcessBuilderImpl.addProcessFromXml(ProcessBuilderImpl.java:249)           at org.drools.compiler.PackageBuilder.addProcessFromXml(PackageBuilder.java:430)           at org.drools.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:470)           at org.drools.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:28)           at com.sample.ProcessTest.createKSession(ProcessTest.java:77)           at com.sample.ProcessTest.main(ProcessTest.java:42) java.lang.RuntimeException: Error building kbase!           at com.sample.ProcessTest.createKSession(ProcessTest.java:89)           at com.sample.ProcessTest.main(ProcessTest.java:42) I'm sure that the processTest.java class is correct because if I delete the instruction : kbuilder.add(ResourceFactory.newClassPathResource("myProcess.bpmn"), ResourceType.BPMN2); I have no error...! :( I can't understand :( please help me -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/610572#610572] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
