Can you place the following lines in ur code: System.out.println(root token name=+rootToken.getNode().getName()); After the following line: Token rootToken = procInst.getRootToken(); Let me know the result.

Hi Ravi, I got following result after adding the sop. root token name=Read Loans Data where 'Read Loans Data' is the state where the instance is waiting.

That means, the root token points to node 'Read Lones Data' and again you are trying to signal to the same node in the following line: rootToken.signla(toReadLoansData); You have already reached that node. I think you can just use token.signal() to execute the node 'Read Lones Data'.

[JBoss-user] [JBoss jBPM] - Re: JBOSS jBPM tool evaluation Help Required
Following changes I did: 1. Read rootToken from the instance I read from the database. Token rootToken = procInst.getRootToken(); 2. signal the rootToken by specifying transition name rootToken.signal(toReadLoansData); But now I am getting following error java.lang.IllegalStateException: couldn't signal token 'Token(/)' : couldn't leave node 'null' over the its transition 'toReadLoansData' at org.jbpm.graph.exe.Token.signal(Token.java:101) at com.sample.SimpleProcessTest.readProcessInstance(SimpleProcessTest.java:199) at com.sample.SimpleProcessTest.testSimpleProcess(SimpleProcessTest.java:25) 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 junit.framework.TestCase.runTest(TestCase.java:154) at junit.framework.TestCase.runBare(TestCase.java:127) at junit.framework.TestResult$1.protect(TestResult.java:106) at junit.framework.TestResult.runProtected(TestResult.java:124) at junit.framework.TestResult.run(TestResult.java:109) at junit.framework.TestCase.run(TestCase.java:118) at junit.framework.TestSuite.runTest(TestSuite.java:208) at junit.framework.TestSuite.run(TestSuite.java:203) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:478) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:344) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:196) I don't understand when it says 'couldn't leave node 'null'' , which node it is refering to and which it getting as NULL. I want to achieve following: - Create Process Definition and store it in database using jbpmSession.getGraphSession().saveProcessDefinition(definition); I am using MSSQL. This process has one State node at which execution should wait for external input. I have to use State and not task-node as i want to take user input. - create process instances of this process and start execution. The instance will wait at the State node. Store the waiting processing instance in database. - Read the saved process instance from the database when external input is received and restart the execution. Please confirm that the approach is correct. Thanks for any better approaches.

please post the processdefinition and the code. Include it in code tags to make it visible (do a preview to see if it is ok) View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=3911740#3911740 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=3911740 --- This SF.net email is sponsored by: Splunk Inc.

you should signal the node passing it a transitionname (not null!) or use the signal without a parameter.
