RE: NoSuchMethodError in MapUtils.getBooleanValue

I am using a context listener and context param in the web.xml as follows.

      <context-param>

            <description>Mule Configuration</description>

            <param-name>org.mule.config</param-name>

            <param-value>

                  /WEB-INF/conf/mule/mule-config.xml

            </param-value>

      </context-param>

      <listener>

            <description></description>

            <display-name>Mule Config Context Listener</display-name>

            <listener-class>

                  org.mule.config.builders.MuleXmlBuilderContextListener

            </listener-class>

      </listener>

The server is WAS 6.1.  I have to say I’ve had a devil of a time trying to resolve classpath issues between Mule and the WAS runtime.  Had to create a special classloader for wsdl4j-1.6.1.jar, etc.  Is there a comprehensive guide for configuring mule for WAS 6.1 somewhere?    

There's probably a wrong commons-lang jar in your classpath. How do you launch Mule?
