  A ClassNotFoundException will result when running a dynamic
  web application (version 2.5 or higher)  that calls code
  from a JAR file located in the WEB-INF/lib directory if the
  JAR has a Main-Class specified in MANIFEST.MF. The problem
  is that the JAR is being treated as an application client
  module (instead of a regular JAR file). This happens only
  when the publishing setting for the server is "Run server
  with resources within workspace" (default setting).
  

Problem conclusion

• All the JAR files located in WEB-INF/lib folder of a dynamic
  web application are treated as regular jar files, even if
  the JAR has a Main-Class specified in MANIFEST.MF.
  
  This issue is fixed in Rational Application Developer
  Version 8.0.2.
