Ralf, I guess I didn't specify in ejb-jar.xml that my ejb's trans-attribute is Required so that weblogic can create an active transanction. Its working now.
I must thank you and Werner for prompt replies. Thanks a lot.

The exception indicates one of 2 situations that could happen at: tx = transactionManager.getTransaction(); 1. the transaction returned from transaction manager is null 2. the status of the transaction returned is not 'acitve' both may happen if your application have not started a transaction. The reason depends on what werner wanted to know about 'declerative' or 'programmatic' transaction handling. at 'declarative' you need to describe in the configuration that your code needs a active transaction and the container handles this for you. at 'programmatic' you need take care to begin a transaction yourself at your application code. this can be done by looking up the transaction manager and call: transactionManager.begin() Hope this help you to continue. Werner and myself are now offline as its getting a bit late in europe. You may need to wait until tommorrow for more help.
