Error on deploying business process
Hello all together,
i changed the sample process from the starter kit in that way, that i added an node with an actionhandler and removed the task-node. My process is described as the above xml-statement:
<?xml version="1.0" encoding="UTF-8"?> <process-definition xmlns="urn:jbpm.org:jpdl-3.1" name="simple"> <start-state name="start"> <transition name="Step1" to="node1"> </transition> </start-state> <end-state name="end"></end-state> <node name="node1"> <transition name="Step2" to="end"></transition> <action class="com.sample.action.MessageActionHandler"> <message>Test</message> </action> </node> </process-definition>
The deployment of the above process ends with the following error:
java.io.IOException: Server returned HTTP response code: 500 for URL: http://localhost:8080/jbpm/upload at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at org.jbpm.ui.util.ProcessDeployer.deployProcessWithServlet(Unknown Source) at org.jbpm.ui.util.ProcessDeployer.access$3(Unknown Source) at org.jbpm.ui.util.ProcessDeployer$1.run(Unknown Source) at org.eclipse.jface.operation.ModalContext.runInCurrentThread(ModalContext.java:346) at org.eclipse.jface.operation.ModalContext.run(ModalContext.java:291) at org.eclipse.jface.dialogs.ProgressMonitorDialog.run(ProgressMonitorDialog.java:447) at org.jbpm.ui.util.ProcessDeployer.showProgressMonitorDialog(Unknown Source) at org.jbpm.ui.util.ProcessDeployer.deploy(Unknown Source) at org.jbpm.ui.editor.form.deployment.DeploymentForm$1.widgetSelected(Unknown Source) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:90) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:66) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:843) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:3125) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:2758) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:1699) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:1663) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:367) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:143) at org.eclipse.ui.internal.ide.IDEApplication.run(IDEApplication.java:103) at org.eclipse.core.internal.runtime.PlatformActivator$1.run(PlatformActivator.java:226) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:376) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:163) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.core.launcher.Main.invokeFramework(Main.java:334) at org.eclipse.core.launcher.Main.basicRun(Main.java:278) at org.eclipse.core.launcher.Main.run(Main.java:973) at org.eclipse.core.launcher.Main.main(Main.java:948)
When i changed the process in a way, that the transition performs my action and not the node i can deploy the process without any problem. The process that can be deployed is the following:
<?xml version="1.0" encoding="UTF-8"?> <process-definition xmlns="urn:jbpm.org:jpdl-3.1" name="simple"> <start-state name="start"> <transition name="Step1" to="node1"> <action name="action1" class="com.sample.action.MessageActionHandler"> <message>Test</message> </action> </transition> </start-state> <end-state name="end"></end-state> <node name="node1"> <transition name="Step2" to="end"></transition> </node> </process-definition>
Can someone find out why i cann't deploy the process with the node actionhandler ???
