ProcessInstanceInfo wont save correctly on JUnit Test environment
diaguirr Jun 22, 2015 4:19 PMI am working on some project that involves the use of JBPM6 as a process engine.
We have tested it via core API and RuntimeManager API, with JBPM 6.1 and 6.2.
In the application environment (Web application using spring on Jboss 7) it works just fine, with process persistance, resuming, events and everything.
The problem is in our Unit Tests. In JBPM 6.1 they work just fine, but in JBPM 6.2, when we test the correct persistence and reumption of processes, we get error due the fact that the processInstanceInfo bytes are never saved (or generetad in any way as far as we could debug).
As we are going to use this on an web environment,so we are trying to emulate it with JNDI an Transaction Manager.
The relevant part of the code is:
JNDI, TM AND DATASOURCE INITIALIZATION
InitialContext ctxt = new InitialContext(); tm=new UserTransactionManager(); tm.init(); ctxt.bind(SUBCONTEXT_NAME+TM_NAME,tm); ds = new AtomikosNonXADataSourceBean(); ds.setUniqueResourceName("psql"); ds.setDriverClassName("org.postgresql.Driver"); ds.setUrl("jdbc:postgresql://localhost:5432/test"); ds.setUser("test"); ds.setPassword("test"); ds.setPoolSize(10); ctxt.bind(SUBCONTEXT_NAME + DS_NAME, ds); ut=new UserTransactionImp(); ut.setTransactionTimeout(300); ctxt.bind(USER_TRANSACTION_NAME,ut); ctxt.bind(JtaTransactionManager.DEFAULT_USER_TRANSACTION_NAME, ut);
(this uses SimpleJNDI and Atomikos as a Transaction Manager, we also tested it with bitronix and H2 with same results)
ACTUAL TEST
System.setProperty("jbpm.ut.jndi.lookup", JtaTransactionManager.DEFAULT_USER_TRANSACTION_NAME); builder = RuntimeEnvironmentBuilder.Factory.get().newDefaultBuilder() .entityManagerFactory(this.getEntityManagerFactory()); if (getUserGroupCallback() != null) builder.userGroupCallback(this.getUserGroupCallback()); builder.persistence(true); builder.addEnvironmentEntry(EnvironmentName.TRANSACTION_MANAGER, this.getTransactionManager()); RuntimeEnvironment environment = builder.get(); manager = RuntimeManagerFactory.Factory.get() .newSingletonRuntimeManager(environment); manager.loadProcess(TEST_FILE); ksession=manager. .getRuntimeEngine(EmptyContext.get()) .getKieSession(); ksession. .startProcess(TEST_FILE_PROCESS_ID, new HashMap<String, Object>());
(This get the transaction manager from jndi and creates the EntityManagerFactory form the persistence unit)
This would result in a single register on the table processInstanceInfor with null on processInstanceInfobytearray column, hence unusable. If we begin and commit the transaction manually (for example before and after the start process call), nothing change at all.
If the test code is run inside a controller , noted with the spring @Transactional notation and deployed as a regultar controller, this works just fine.
We really need to set a proper test enviroment so i am really troubled with this issue.
Note that all this works perfectly with jbpm 6.1
