WLS10 PRE CLASSPATH and apache commons

Question

Hi,
Our web application requires latest versions of apache-commons especially commons-lang.jar, After reading through thread; came to know that if we add PRE CLASSPATH entry for latest versions of these jar, application work as expected, and our application does not use any of weblogic APIs.
Concern is that, some reason weblogic.jar is referencing oldest versions of these jars. Would that cause problem with server? also noticed that Console application is struts based application, would it break that application?
Please let us know,
Thanks,
Anil G

Hi Anil,
It is always better and recommended that if you want to use any other version of a Jar which is also available with the WebLogic Installation ...then Please Place that Jar inside your Application "<YOUR_EAR_APP>/APP-INF/lib" (If u are using EAR Application) or inside "<YOUR_WAR_APP>"/WEB-INF/lib" directory if you are using WebApplication. And then Apply ClassFiltering. As described in the below Post to change to Loaded Class Loading strategy for a particular Application without Changing any Jar for Whole WebLogic Server.
