Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of WebSphere Application Server        *
  *                 version 6 who enable servlet serving by      *
  *                 class name.                                  *
  ****************************************************************
  * PROBLEM DESCRIPTION: If servlet serving by class name is     *
  *                      enabled and a null (empty) servlet      *
  *                      name is specified, a                    *
  *                      NullPointerException will be thrown.    *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When servlet serving by class name is enabled and a null
  (empty) servlet name is specified, a missing logic check will
  cause a NullPointerException to be thrown.
  

Problem conclusion

• The servlet name logic checking has been fixed to prevent a
  NullPointerException from being thrown. In the case that a
  null (empty) servlet name is specified, a "no target for URI"
  exception will be thrown.
  
  The fix for this APAR is currently targeted for inclusion
  in fixpack 6.0.2.13 and 6.1.0.1.
