Xa transaction sample doesn't workk

Question

I've tried to work through the java example concerning xa transaction, but it doesn't work.
The program cannot create the resource, a null value is always returned.
Sample code from oracle :
// Create a XADataSource instance
OracleXADataSource ds = new OracleXADataSource();
ds.setURL("jdbc:oracle:thin:@dolphin:1521:TEST");
ds.setUser("sel");
ds.setPassword("poivre");
// get a XA connection
XAConnection xaConn = ds.getXAConnection();
// Get a logical connection
Connection conn1 = xaConn.getConnection();
Xid xid1 = createXid(111,111);
until this everything work but the following get XA Resource doesn't work.
// Get XA resource handle
XAResource res = xaConn.getXAResource();
If someone knows about this, thank you in advance for help.

A transaction timeout will not and cannot terminate user code as there
is no Java API for doing so. If you wish the user code to timeout, try
using the "setQueryTimeout()" method on the SQL statement. The WebLogic
JTS will timeout the transaction using another thread and will prevent
any JDBC activity associated with the global transaction from being
commited.

"Dear Support,
We encounter problems with transaction timeout and details as follows:
A swing UI calls a session bean in which a DAO(Data Access Object) is invoked,
In this DAO, it try to invoke a store procedure like following :
dateSource = getTxDataSource();
conn = (Connection)dataSource.getConnection();
cstmt = conn.prepareCall("{call PK_AP_OO_CATCH_UP.P_AP_MAIN(?,?) }");
cstmt.registerOutParameter(...........);
cstmt.execute();
When a irrevalent guy carelessly locked the table , the swing keep running for 5 hours and
the transaction never throws exception ( both JTA and trans-timeout-seconds are set).
I've also survey docments , however, we are not sure about the definition of Container-managed transactions
and Bean-managed transactions. So there are two problems to be solved :
1. How to solve the timeout problem as the sample code above for calling store procedures,
and what kind of transctions it uses according to the definition ?
2. If a normal sql statement is executed as follows , should we declare explicit transaction ( begin and commit) ? %
