Thanks Chris & kretschmer. But one small doubt in it,, What happens to update or insert query?

Is there any possibility to mention max time a query can execute from DBCP side? our DB is Postgres and Container is tomcat 6. we dont want to give the timeout in postgres for all query but need to set in application side based on differnet needs? Is it possible?

Is there anyother way to specify the query execution time out while establishing connection with the help of DBCP in tomcat?

 Example, if a query executed from web application then it should not execute more then 22mins. If it execute more then that means query shold be cancelled from postgres(important) and java should get exception on this event. Is it possible?

You can set statement_timeout per session.

Not sure what happens on the java side when the exec time is hit but the query is cancelled in postgres.
