What is the cause of getting Transaction Timeout?

[Mohammad Norouzi]

Hello
I am using a bean managed stateless SB in which another business method is called within a method as follow:

tx.begin();
journalService.doSomething();
tx.commit();

This code is executing within a for-loop and sometimes the folliwing exception is occurs. Anyone knows what is the problem?

thanks

The message says you have a timeout. Is the code taking a long time? Is it hanging?

Yes some of methods have a huge operations and may have a lot of CRUD.
I've set the transaction time out to a higher value but still getting this error.
How we can avoid this problem?
