Hi Ray,
Thanks for the reply on the second point. I had tried the same using
the points which you had given, But the driver is still the one in the
ejb-location and no transaction rollback had taken place. I guess I
will have to wait about the data source.
Thanks very much
Regards
Aby

Subject: Re: Transaction and DriverManagerXADataSource
Can't help with your first question, but can with the second:
In your ejb-jar.xml file(s) there is a section called
<assembly-descriptor>
and within that, you can set up security roles on methods, etc but can
also
define container transactions in a section called (you guessed it)
<container-transaction> which looks like this:
<assembly-descriptor>
.
.
.
<container-transaction>
<description> Give this a required transaction </description>
<method>
<ejb-name>YourEJBName</ejb-name>
<method-intf>Remote</method-intf>
<method-name>deposit</method-name>
</method>
<method>
.
</method>
.
.
List all of your methods for which you want a 'required
transaction'
<trans-attribute>Required<trans-attribute>
</container-transaction>
Check out the ejb specs at java.sun.com as they describe all of this
quite well.
The GUI tools often hide what is going on! (good & bad)
