I'd like to read process definition and have it in KnowledgeBase, so that  I can run process, etc... but as I mentioned I was unable to get those processes... I don't know maybe I am doing something wrong. Here's my code snippets: ProcessBuilderFactory.setProcessBuilderFactoryService(new ProcessBuilderFactoryServiceImpl()); ProcessMarshallerFactory.setProcessMarshallerFactoryService(new ProcessMarshallerFactoryServiceImpl());        ProcessRuntimeFactory.setProcessRuntimeFactoryService(new ProcessRuntimeFactoryServiceImpl()); BPMN2ProcessFactory.setBPMN2ProcessProvider(new BPMN2ProcessProviderImpl());       KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent("default guvnor agent");      kagent.applyChangeSet(ResourceFactory.newClassPathResource("ChangeSet.xml")); kbase = kagent.getKnowledgeBase(); ChangeSet.xml: <change-set xmlns='http://drools.org/drools-5.0/change-set'             xmlns:xs='http://www.w3.org/2001/XMLSchema-instance'             xs:schemaLocation='http://drools.org/drools-5.0/change-set http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/... >     <add>         <resource source='http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/defaultPackage/LATEST' type='PKG'/>     </add> </change-set> and when I want to list all loaded processes in index.jsp: <%      if (connector.kbase.getProcesses().size() > 0) {           for (Process proccess : connector.kbase.getProcesses()) {                out.println("Process " + proccess.getName() + " loadded succesfully");           }      } else {           out.println("No proccess loaded");      } %> Else part is displayed. Do I need to do soemthing first in guvnor with this package? Some kind of export or what? Maybe it has something to do with this process status? Is Draft ok? I don't know. Any idea what could be wrong? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/598562#598562] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]

Yes and the package is built successfully. 2. What do you mean by builds? If you mean that if the first code snippet is done before the third, than yes I do build the package before kbase.getProcesses() ProcessBuilderFactory.setProcessBuilderFactoryService(new ProcessBuilderFactoryServiceImpl()); ProcessMarshallerFactory.setProcessMarshallerFactoryService(new ProcessMarshallerFactoryServiceImpl());        ProcessRuntimeFactory.setProcessRuntimeFactoryService(new ProcessRuntimeFactoryServiceImpl()); BPMN2ProcessFactory.setBPMN2ProcessProvider(new BPMN2ProcessProviderImpl());       KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent("default guvnor agent");      kagent.applyChangeSet(ResourceFactory.newClassPathResource("ChangeSet.xml")); kbase = kagent.getKnowledgeBase();   this is a part of my connector's constructor... so the third snippet looks actually like that: 3. Yes I do... I have catch clause in which I set error variable and print it in index.jsp ... there's no error -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/598924#598924] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
