[JBoss jBPM] - Token.signal() for bpel process definitions
by b_
Hi all,
I am trying to do something similar to the HelloWorld example (that ships with jbpm-jpdl), but through a bpel process definition.
This is the code for the jpdl helloWorld example:
|
| ProcessDefinition processDefinition = ProcessDefinition.parseXmlString(
| "<process-definition>" +
| " <start-state>" +
| ................
| ................
| "</process-definition>"
| );
|
| ProcessInstance processInstance =
| new ProcessInstance(processDefinition);
|
| Token token = processInstance.getRootToken();
|
| token.signal();
|
| ...
| ...
|
This code works fine ... however when i try to do the same thing using a bpel process definition using the following code:
|
|
| ZipInputStream zis = zis = new ZipInputStream(new
| BufferedInputStream(Thread.currentThread().getContextClassLoader().getResourceAsStream("helloWorldBpel.zip");));
|
| ProcessArchive processArchive = null ;
|
|
| try {
| processArchive = new ProcessArchive(zis);
| } catch (IOException e) {
| .....
| }
| ProcessDefinition processDefinition = processArchive.parseProcessDefinition();
|
| ProcessInstance processInstance =
| new ProcessInstance(processDefinition);
|
| Token token = processInstance.getRootToken();
|
| token.signal();
|
|
i get the following exception:

| Is this possible to do with a bpel process definition? (there is infact a package org.jbpm.bpel.graph.exe which i guess contains execution related artifacts for bpel graph definitions). Am i missing something?
