Wrong class loading sequence

When you configure Rule Execution Server or Decision Center, if you do not change the class loading sequence, an error message is displayed.

Symptoms

You get an error message similar to the following one: Error 500: java.lang.NoSuchMethodError: org/apache/myfaces/taglib/core/LoadBundleTag.setBasename(Ljava/lang/String;)V

Causes

The class loading sequence is set to parent first.

Environment

Rule Execution Server or Decision Center for distributed platforms or for Linux® on z Systems®.

Resolving the problem

After you have deployed the EAR file, you must change the order in which classes are loaded.
