Thank you for your response. However, I?m still unclear as to what I need to
do to fix the issue in my code. The example about RetryingTransactions is
referring to an EJB, and my code is in a simple servlet running in Tomcat under
JBoss.
The snippet of code below is my method for obtaining a JTA connection from the
pool. As you can see it does the JNDI lookup, fetches the DataSource object,
and tries to return a Connection object. Once I have the DataSource, how can I
determine if the connection I get will be dead? Or, if I trap the exception,
how can I remove the dead transaction from the pool and get a live one?
private static Connection getJBossJTAConnection(String poolName) throws
DataException
| {
| Connection conn = null;
| try {
| InitialContext ctx =
JNDIManager.getInstance().getInitialContext();
| DataSource ds = (DataSource)ctx.lookup("comp/env/jdbc/"
+ poolName + "Tx");
| conn = ds.getConnection();
| }
| catch ( Exception e ) {
| e.printStackTrace();
| throw new DataException( e.getMessage() );
| }
| return conn;
| }
