In my implementation, in the start method of the adapter, I start a timer
using the method createTimer of BootStrapContext. In the run method of the
timer, I create an instance of my work interface implementation and call its
WorkManager.scheduleWork passing this instance.
The implementation of Work interface does the lookup on ConnectionFactory
and calls getConnection on it.
Following is the code
----------------------------------------------------------------------------
-------------------------------
public void run()
{
System.out.println("In the run of OutboundWork");
String JNDIName = "test/OutboundAdapter";
try
{
Context ctx = new InitialContext();
System.out.println("Obtained the initial context.");
Object object = ctx.lookup(JNDIName);
System.out.println("Class name is: " +
object.getClass().getName());
ConnectionFactory ctxFactory =
(OutboundConnectionFactory)object;
System.out.println("ConnectionFactory obtained: " + ctxFactory +
" " + ctxFactory.getClass().getName() );
Connection connection = ctxFactory.getConnection();
System.out.println("Connection obtained: " + connection + " " +
connection.getClass().getName() );
}
catch(Exception ex)
{
System.out.println("Invalid class returned from lookup.");
ex.printStackTrace();
}
}
----------------------------------------------------------------------------
--------------------------------
Is there something incorrect in this implementation.
