XA error with Oracle 9.2.0.x / Weblogic 7 sp2

Question

Hi,
I have encountered some problems when accessing Oracle 9i (9.2.0.2) via
Weblogic7 sp2 .
The problem occurs when a stateless session bean invokes a DAO that get a
connection from the datasource. The SLSB transaction attribute is set to
'required'.
This problem does not when using oracle.driver.OracleDriver or using Oracle
9.0.1.
Please help.
Thanks!
Regards...

Which version of oracle database are you trying to connect to? we have seen some problems with oracle 920 thin driver. It will be good to use 9013 thin driver instead for now.
