In my project,i use the code below to configure the persistence:
try {
PoolingDataSource ds = new PoolingDataSource();
ds.setUniqueName("jdbc/testDS");
ds.setClassName("com.mysql.jdbc.jdbc2.optional.MysqlXADataSource");
ds.setMaxPoolSize(3);
ds.setAllowLocalTransactions(true);
ds.getDriverProperties().put("user", "root");
ds.getDriverProperties().put("password", "root");
ds.getDriverProperties().put("URL", "jdbc:mysql://localhost:3306/jbpm5");
ds.init();
// load up the knowledge base
KnowledgeBase kbase = readKnowledgeBase();
// start a new process instance
EntityManagerFactory emf = Persistence
.createEntityManagerFactory("org.jbpm.persistence.jpa");
Environment env = KnowledgeBaseFactory.newEnvironment();
env.set(EnvironmentName.ENTITY_MANAGER_FACTORY,
emf);
env.set(EnvironmentName.TRANSACTION_MANAGER,
TransactionManagerServices.getTransactionManager());
// create a new knowledge session that uses JPA to store the runtime
// state
StatefulKnowledgeSession ksession=null;
ksession= JPAKnowledgeService.newStatefulKnowledgeSession(
kbase,
null,
env);
JPAWorkingMemoryDbLogger logger = new JPAWorkingMemoryDbLogger(ksession);
ksession.getWorkItemManager().registerWorkItemHandler("Human Task", new WSHumanTaskHandler());
// start a new process instance
Map<String, Object> params = new HashMap<String, Object>();
params.put("employee", "krisv");
ksession.startProcess("com.sample.evaluation",params);
logger.dispose();
} catch (Throwable t) {
t.printStackTrace();
}
However,when i start a new processinstance and try to complete the first task,exception happens just like this:
Registered human task listener

[jBPM] - Go to a node already executed due to a task abort

Hello,
I want to do the following and i don't find the way to do it with jbpm5:
* I have a workflow that represents a wizzard like functionality.
* Each step is represented by a human task, when the user press the next button the workingitem is completed and the workflow advances to the next human task.
* If the user press Prev the task shold be aborted and the flow should return to the last sucessfully executed node. Internally it will rollback the changes made in this step.
I have tried to put diverge node with a Secuence Flow that go backward to the node but the editor doesn't allow me. I don't know if it is posible. If I do an abort in the human task, the flow continues to the next node instead of stay there or go backward.
How do you think i can do this task?
Regards,
Carlos
