========================================================================

Here is the solution to this issue.

Configure below listener in the web.xml of your web application.

========================================================================
  <listener>
          <listener-class>atg.taglib.dspjsp.RegisterELResolverServletContextListener</listener-class>
    </listener>
========================================================================

To use this listener your web application must use the servlet 2.5 schema or greater.
