Token.signal() for bpel process definitions
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:
org.jbpm.JbpmException: token 'Token(/)' can't be signalled cause it is currently not positioned in a node

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?
