In which Environment are you running EL. If you are in a Java ee and run|
you session beans container managed, the the EE container should handle

deal with transactions yourself. This is why EL is complaining that
there is no transaction active. The select query is only reading, and
reading access does not require a transaction.

You need to encapsulate all your writing queries with a transaction.
P.S. If you are running container managed transactions on an
Applicationserver (e.g. JBoss), i think there is a configuration
problem, because the container should handle the transactions for you.
