Re: Casting DBCP Connection to OracleConnection

Compile fail or run-time fail?

If compile fail - you need a nightly of dbcp.
If run-time fail, you may need to use getInnermostDelegate() instead

2. OracleConnection oc = (OracleConnection)pc.getDelegate();

All dbcp objects have a getDelegate() method (I think). 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.

I have the same problem. 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 ?

Thanks
