RE: [Springframework-developer] re: OracleLobCreator

[Bronwen C. <bro...@ya...>]

Hi I have:

Weblogic 8 service pack 2 
ojdbc.jar (Oracle9i 9.2.0.1 JDBC Drivers) 
Oracle9i 
I have set up the connection pool using the jdbc:oracle:thin (oracle thin
drivers (not weblogic ones)  

Actually I managed to find some information (very little) one from a
hibernate mail, suggested using the getPhysicalConnection() instead of
createTemporary, but this method does not seem to available on the CLOB
class??

Bronwen,

In order to pinpoint the problem quicker - what version of WebLogic, 
Oracle and JDBC drivers are you using?
