APAR status

• Closed as program error.

Error description

• JSPG0046E: Unable to locate tagfile <custom tag name> when
  using a custom tag with String[] as attribute type
  
  All these JSPs are using  custom tags  (files .tag located in
  WEB-INF/tags without TLD). These custom tags cannot be
  processed by WebSphere due to the error "JSPG0046E: Unable to
  locate tagfile".
  

Local fix

• After changing the attribute type to "java.lang.Object", the
  problem does not occur anymore (but this workaround will
  require to rewrite all these tags in order to type cast the
  attributes !).
  

Problem summary

• ****************************************************************
  * USERS AFFECTED:  IBM WebSphere Application Server Full and   *
  *                  Liberty Profile version 8.5.5 users of      *
  *                  JavaServer Pages (JSP).                     *
  ****************************************************************
  * PROBLEM DESCRIPTION: A custom tag file which has an array    *
  *                      as an attribute type will fail to       *
  *                      compile.                                *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  If the expected type of a custom tag attribute is an array the
  following exception will occur:
  com.ibm.ws.jsp.JspCoreException: JSPG0047E: Unable to locate
  tag library for uri /WEB-INF/tags
  at
  com.ibm.ws.jsp.translator.visitor.tagfiledep.TagFileDependencyVi
  sitor.visitCustomTagStart(TagFileDependencyVisitor.java:76)
  at
  com.ibm.ws.jsp.translator.visitor.JspVisitor.processJspElement(J
  spVisitor.java:366)
  at
  com.ibm.ws.jsp.translator.visitor.JspVisitor.processChildren(Jsp
  Visitor.java:419)
  An example of an attribute directive in a tag file which would
  cause the exception:
  <%@ attribute name="test" required="true"
  type="java.lang.String[]" %>
  

Problem conclusion

• The JSP Container was modified to process the array definition
  properly.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5.4. Please refer to the Recommended Updates page
