How can I force it to use the newer

I want to use commons-net-2.0.jar from my code.

WebLogic uses a parent class loader first strategy and you basically have two options to tweak this behavior:

• Use the prefer-web-inf-classes element in a weblogic.xml Web application deployment descriptor (that goes in WEB-INF next to the web.xml) ~or~
• Package your war insider an EAR and use WebLogic Filtering classloader that you configure in a weblogic-application.xml descriptor (that goes in META-INF next to the application.xml)

Here is an example weblogic.xml:

    
        true
     

Here is an example weblogic-application.xml:

    
        webapp.encoding.default
        UTF-8
    
    
        javax.jws.*
    

The former option is simpler but is global to the webapp. The later introduces more complexity if you're not currently using an EAR packaging but gives finer control.
