Hi,
I have been trying to find my way through, debugging through the code. So
far, I think, I have managed to initialize a server instance with the code
below,
TransactionManager transactionManager = new Current();
BasicDataSource basicDataSource = new BasicDataSource();
Properties odeProperties = new Properties();
SimpleScheduler scheduler = new SimpleScheduler(new
GUID().toString(), new JdbcDelegate(basicDataSource), odeProperties );
scheduler.setExecutorService(Executors.newCachedThreadPool());
scheduler.setTransactionManager(transactionManager);
BpelDAOConnectionFactoryImpl dcf = new
BpelDAOConnectionFactoryImpl(null);
BpelServerImpl bpelServer = new BpelServerImpl();
bpelServer.setDaoConnectionFactory(dcf);
bpelServer.setScheduler(scheduler);
bpelServer.init();
Is this the right approach?
Thanks
Meeraj
