DBCP Connection.getDelegate () class cast problem

["Dong, Lily/Sloan-Kettering Institute" <do...@MSKCC.ORG>]

Hi.

After updating tomcat to 5.0,  part of our system stopped working.  Looked
at the source code and found out the line

((PoolableConnection)conn_l).getDelegate()

caused java.lang.ClassCastException exception.  But the same code works fine
for Tomcat 4.1.

Any idea what went wrong?

Thanks,
Lily

A little more info is needed:

Version of DBCP and exact tomcat versions?
Do you have a DBCP jar in the WEB-INF/lib directory of your 
application or only in tomcat/common/lib?
Do you create your own pool or use JNDI? (context configuration?)
