Transaction timeouts behaviour - explanation needed

[vasiniy pupkin]

Hello all,

I'm a newbie to Weblogic and would like to understand how transaction timeouts work in Weblogic. I have a EJB2 application running under Weblogic 10.3 and using Oracle 11g database via thin jdbc driver.
I noticed that if I set trans-timeout-seconds in deployment descriptor it terminates sql queries if they overflow the limit. Say I have timeout set to 10 seconds, it will stop executing sql query after that time and immediately return exception to caller of the current EJB method. This is just perfect!
What I want is to understand how that is done, does it proxy driver somehow? Will it work with other databases, Postgresql for example?
Can I port same behavior to other app servers, JBoss for example.

Thank you in advance.
