Migration from Bitronix to JBossTS
Greetings,
Recently I've been assigned to change Bitronix transaction manager to JBossTS. It's a standalone application with hibernate and spring transactions (used by jbpm process).
I am very new to JBoss and I wonder if there is a quick way to migrate from Bitronix?
For initialization purposes all I needed was code listed below. Can I configure JBossTS in a similar manner?

import bitronix.tm.resource.jdbc.PoolingDataSource;
private static PoolingDataSource ds = new PoolingDataSource();
// init connection pool
static{
ds.setUniqueName("jdbc/jbpm-ds");
// NON XA CONFIGS
ds.setClassName("org.h2.jdbcx.JdbcDataSource");
ds.setMaxPoolSize(3);
ds.setAllowLocalTransactions(true);
// TODO read DB params from config file
ds.getDriverProperties().put("user", "user1");
ds.getDriverProperties().put("password", "");
ds.getDriverProperties().put("URL", "jdbc:h2:./db/db");
// XA CONFIGS
// ds.setClassName("bitronix.tm.resource.jdbc.lrc.LrcXADataSource");
// ds.setMaxPoolSize(3);
// ds.setAllowLocalTransactions(true);
// ds.getDriverProperties().put("user", "user1");
// ds.getDriverProperties().put("password", "");
// ds.getDriverProperties().put("Url", "jdbc:h2:./db/db");
// ds.getDriverProperties().put("driverClassName", "org.h2.Driver");
ds.init();
}
// getting EntityManager Factory

APP_PU("h2"),

return this.puName;
}
}
private static Map<PUnit, EntityManagerFactory> entityManagerFactoriyMap = new HashMap<PUnit, EntityManagerFactory>();
public static EntityManagerFactory getEntityManagerFactory(PUnit persistenceUnitEnum) {
if (!entityManagerFactoriyMap.containsKey(persistenceUnitEnum) || !entityManagerFactoriyMap.get(persistenceUnitEnum).isOpen()) {
EntityManagerFactory emf = createEntityManagerFactory(persistenceUnitEnum);
entityManagerFactoriyMap.put(persistenceUnitEnum, emf);
return emf;
} else {
EntityManagerFactory emf = entityManagerFactoriyMap.get(persistenceUnitEnum);
return emf;
}
}
