RE: Casting DBCP Connection to OracleConnection - Solved IT!
Now it's working!! Thanks guys! I'm sorry, but i think to have an old release of commons-dbcp.jar, and i don't' find the getDelegate() method. It's in org.apache.commons.dbcp.PoolableConnection class?? In my tomcat common/lib; apparently it is the debug version of Oracle's jdbc implentation.

If you find a solution, please reply HI, I am using Tomcat 4.1.18 with Oracle 9i. When I try to cast the Connection returned from DBCP to OracleConnection I get a ClassCastException . Anyone here know how to cast correctly ?

RE: Casting DBCP Connection to OracleConnection - Solved IT!
I'm sorry, but i think to have an old release of commons-dbcp.jar, and i don't' find the getDelegate() method. It's in org.apache.commons.dbcp.PoolableConnection class?? In my tomcat common/lib; apparently it is the debug version of Oracle's jdbc implentation. Download classes12.zip ( and rename to classes12.jar ) from Oracle site.

Where do you find ojdbc_g.jar? I was using ojdbc_g.jar instead of classes12.zip ( i.e classes12.jar ) Sundar -Original Message- From: Chakravarthy, Sundar Sent: Monday, March 31, 2003 11:11 AM To: Tomcat Users List Subject: RE: Casting DBCP Connection to OracleConnection Strange .. the getDelegate().getClass().getName() returns oracle.jdbc.driver.OracleConnection . But the cast fails at runtime.

If compile fail - you need a nightly of dbcp. If run-time fail, you may need to use getInnermostDelegate() instead -Tim Chakravarthy, Sundar wrote: I tried the following with no success, 1.

But you'll need to do 2 casts. - dbcpConn = (DBCPClassCast)conn-- The dbcp connection - myOraConn = (OraClassCast)dbcpConn.getDelegate() -- Get the underlying implementation Look at the DBCP javadocs for the correct class names. BUT you'll need to use a nightly build of dbcp to do this since the version shipped with tomcat doesn't have the getDeletgate() methods. -Tim Marco Rossi wrote: I have the same problem.
