How to prefer JARs from Weblogic domain over those from weblogic system

I am using Weblogic Server 12.1.1 and copied some JARs to my domain's lib folder. One of the JARs is a org.apache.commons.io jar. Now I have the problem that Weblogic itself comes with a different version of commons-io in its system classpath and so I get NoSuchMethodErrors. Is there any way to configure Weblogic to prefer the libs from domain over those from Weblogic system?

The Filtering Classloader works only on those JARs provided with the application (WEB-INF/lib).

Solution

  • If you need to put JARs into the domain /lib, I think you have to edit the setDomainEnv.cmd and modify PRE_CLASSPATH variable.

    Example: set PRE_CLASSPATH=C:\myinstallation\Middleware\wlserver_12.1\domains\mydomain\lib\myjar.jar

    But, if is possible to put JARs in WEB-INF/lib or APP-INF/lib, then use @Blekit solution, it's cleaner.
