Problem summary

  • ****************************************************************
    * USERS AFFECTED:  IBM Websphere Application Server version    *
    *                  7.0 users of JavaServer Pages(JSP)          *
    ****************************************************************
    * PROBLEM DESCRIPTION: Both JavaServer Pages Standard Tag      *
    *                      Library (JSTL) and the JSP API code use *
    *                      the same key in the PageContext         *
    *                      Hashmap.                                *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
     Due to JSTL and the JSP API code using the same key
    ('org.apache.taglibs.standard.ImplicitObjects') in the
    PageContext Hashmap, a ClassCastException can occur.  An example
    of the exception is:
    
    org.apache.taglibs.standard.lang.jstl.ImplicitObjects
    incompatible with
    javax.servlet.jsp.el.ImplicitObjectELResolver$ImplicitObjects
    java.lang.ClassCastException:
    org.apache.taglibs.standard.lang.jstl.ImplicitObjects
    incompatible with
    javax.servlet.jsp.el.ImplicitObjectELResolver$ImplicitObjects
    at
    javax.servlet.jsp.el.ImplicitObjectELResolver$ImplicitObjects.ge
    tImplici
    tObjects(ImplicitObjectELResolver.java:579)
    at
    javax.servlet.jsp.el.ImplicitObjectELResolver.getValue(ImplicitO
    bjectELR
    esolver.java:140)
    at
    javax.el.CompositeELResolver.getValue(CompositeELResolver.java:1
    43)
    

Problem conclusion

  • The JSTL ImplicitObjects object was modified to use
    'org.apache.taglibs.standard.lang.jstl.ImplicitObjects' as a
    key which is different than the key that the JSP API uses.
    
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 7.0.0.17.  Please refer to the Recommended Updates
