Our application which was on Websphere5.1 and Oracle 9i was recently upgraded to Websphere220.127.116.11 and Oracle 10g. With the same set of Code and other setting such as Datasopurces, connection pooling etc, we are getting an error as :
DSRA9110E: ResultSet is closed Instead of the complete code I will post the logic and some pseudo code on this.
I have also faced this problem in my application , I used to get connection error from the method where connection object was retrieved can you put sop in getConnection() and check if before returning the connection object the object is not Null

Thank You Dilip. We did put in a lot of SOPs and checked, but the connection object is not null or closed. Even the ResultSet is not null. Which is what is strange. I hope we get a resolution for this quickly.
Are you using stateless session bean or stateful session bean ? my another question is why are you having connection and member variable of class.
Assuming you are using stateless session bean. The instance of stateless session beans are shared among multiple request. How do you ensure that other request will not cause problem like closing connction etc ect...
Can you give a try to your code having connection as local variable....

Many Thanks Shailesh. However none of the above apply to the scenario. We did a lot of Research and testing at our end. Following are the scenarios and the conclusions.
We tested the application by connecting to DataSource of Oracle 9i. It worked perfectly fine. No resultsets were closed.
The same piece of code connecting to Oracle 10g datasource fails.
Next we tried connecting to Oracle 10g through DriverManager instead of Datasource. It worked perfectly fine.
Our conclusion is that Oracle 10g datasource has some issues which we are not clear about. Is it because we are updating the same table as that of the resultset in the same connection that the resultset is getting closed? We are not too sure of this. Would be glad if anyone can shed some light on this.
