(Doc ID 2253462.1)

Last updated on APRIL 26, 2017

Applies to:

Oracle WebLogic Server - Version 10.3.6 to 10.3.6
Information in this document applies to any platform.

Symptoms

Getting class loading exceptions when trying to deploy application using OpenSAML3 with Weblogic Server 10.3.6. Tried with <prefer-web-inf-classes>true</prefer-web-inf-classes> but failed with other exceptions.

It was found that workaround is deleting OpenSAML jar files bundled with Weblogic Server, which locate at /modules directory, including com.bea.core.bea.opensaml_1.0.0.0_6-2-0-0.jar and com.bea.core.bea.opensaml2_1.0.0.0_6-2-0-0.jar.
