org.hsqldb.jdbc.pool.JDBCXID
- All Implemented Interfaces:
Xid
Implementation of Xid for tests.
// Example usage: JDBCXADataSource ds = new JDBCXADataSource(); ds.setUser(user); ds.setPassword(password); ds.setUrl(jdbcUrl); XAConnection xaCon = ds.getConnection(); Connection con = xaCon.getConnection(); Xid xid = JDBCXID.getUniqueXid((int)Thread.currentThread().getId()); XAResource xaRes = xaCon.getXAResource(); // Start the transaction. System.out.println("Starting XA transaction with xid = " + xid.toString()); xaRes.setTransactionTimeout(0); xaRes.start(xid,XAResource.TMNOFLAGS); // Do work here .... // Commit the transaction. xaRes.end(xid,XAResource.TMSUCCESS); xaRes.commit(xid,true); // Cleanup. con.close(); xaCon.close();

getUniqueXid
Retrieves a randomly generated JDBCXID. The newly generated object is based on the local IP address, the giventhreadId
and a randomly generated number using the current time in milliseconds as the random seed. Note that java.util.Random is used, not java.security.SecureRandom.- Parameters:
threadId
- can be a real thread id or just some convenient tracking value.- Returns:
- a randomly generated JDBCXID
