  • The following error occurs when the taglib is defined in the
    web.xml file:

    Here are the taglib definitions:
    
    Web.xml:
    
    <taglib>
    <taglib-uri>/WEB-INF/c.tld</taglib-uri>
    <taglib-location>/WEB-INF/c.tld</taglib-location>
    </taglib>
    
    <taglib>
    <taglib-uri>/WEB-INF/fn.tld</taglib-uri>
    <taglib-location>/WEB-INF/fn.tld</taglib-location>
    </taglib>
    
    
    JSP page:
    
    
    <%@ taglib uri="/WEB-INF/c.tld" prefix="c" %>
    <%@ taglib uri="/WEB-INF/fn.tld" prefix="fn" %>
    
    The problem does not occur on WLP 8.5.5.4.  It occurs on WLP
    8.5.5.9 and 8.5.5.10.
    

Local fix

  • Add the class org.apache.taglibs.standard.tlv.JstlCoreTLV to
    the application classpath.
    

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server Liberty - JavaServer Pages (JSP) 2.2 *
    *                  and 2.3                                     *
    ****************************************************************
    * PROBLEM DESCRIPTION: A JSPG0236E error message will be       *
    *                      thrown if a web module includes a Tag   *
    *                      Library Descriptor (TLD) file           *
    *                      referencing classes in package          *
    *                      org.apache.taglibs.standard.tlv or      *
    *                      org.apache.taglibs.standard.tei.        *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    An error message will be reported in the standard output file if
    a web module includes a TLD containing references to package
    org.apache.taglibs.standard.tlv or
    org.apache.taglibs.standard.tei at any level of the WEB-INF
    folder.
    
    The error message looks like the following:
    
    JSPG0236E: The JSP container failed to load the
    TagLibraryValidator class
    [org.apache.taglibs.standard.tlv.JstlCoreTLV]
    at com.ibm.ws.jsp.taglib.TldParser.parseTLD(TldParser.java:292)
    at

    at
    com.ibm.ws.jsp.taglib.TagLibraryCache.loadWebInfMap(TagLibraryCa
    che.java:608)
    ...
    

Problem conclusion

  • The JSP 2.2 and 2.3 features were modified to make classes of
    org.apache.taglibs.standard.tlv and
    org.apache.taglibs.standard.tei available to the application
    classloader; resolving the JSPG0236E error.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 17.0.0.2.  Please refer to the Recommended Updates page for
    delivery information:
    http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
    

Temporary fix

  • A workaround is to include the content of packages
    org.apache.taglibs.standard.tlv and
    org.apache.taglibs.standard.tei to the web module?s classes or
    lib folder.
