Connection pool problem

[Rauf Khan <mk...@gmail.com>]

Hi,

  Iam trying to connect to oracle database through struts database
connection pool, also i have placed commons-dbcp.1.2.1.jar in web-inf/lib
folder.

  It is throwing the following error:

java.lang.NoClassDefFoundError: org/apache/commons/pool/impl/GenericObjectPool
	java.lang.Class.getDeclaredConstructors0(Native Method)
	java.lang.Class.privateGetDeclaredConstructors(Unknown Source)

You need Jakarta Commons Pool:
http://jakarta.apache.org/commons/pool/

Anyway notice that Struts DataSource support has been removed since 1.2 
version (correct me if I am wrong), so you probably should use JNDI to 
use a DataSource, or Spring IoC (that I prefer).

Ciao
