RE: Using Custom JSP tags in WebSphere 3.5.3 -- JAVA400-L

David,

Thanks for the response.  I created a JSP from the sample code you sent me,
When I run the JSP I get the same error I descibed previously:

Error 500
An error has occured while processing
request:http://localhost:8080/StrutsTest.jsp
Message: "Directive: Invalid attribute, prefix"

Target Servlet: jsp
StackTrace:
----------------------------------------------------------------------------
----
Root Error-1: "Directive: Invalid attribute, prefix"

com.ibm.servlet.engine.webapp.WebAppErrorReport: "Directive: Invalid
attribute, prefix"

I completed a tutorial VisualAge for Java for Websphere by Craig Pelkie a
few months ago.  In that tutorial, one of the exercises was to create a JSP
using the Websphere custom tags.  It used tags for iteration and for JDBC
connections.  In that example, it used the prefix tsx for the custom tags
but there was no directive statement to define the tag library.  I assume
because these were the websphere custom tags and no directive statement was
needed.  The application worked fine.  Does this imply that the only custom
tags that can be used for Websphere 3.5.3 are in the Websphere tag library?

Stephen,

Does WebSphere 3.5.3 support JSP 1.1? I think it may only support the
1.0
specification. I use Struts quite a bit but use Tomcat. You can see if
it is your
bean or the tablib support by doing using one of the struts tags. Try
something like:

<%@ page language="java" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="logic" %>
<html:html locale="true">
  <head>
    <title>Test</title>
  </head>
  <body>
      <logic:notPresent name="org.apache.struts.action.MESSAGE"
scope="application">
        <font color="red">
          ERROR:  Application resources not loaded -- check servlet
container
          logs for error messages.
        </font>
      </logic:notPresent>
  </body>
</html:html>

This should compile and work/fail depending on whether you have an
ApplicationResources class set up.

I am using Websphere 3.5.3.  I have created an application that returns
a
collection of Order History beans.  I am trying to use a JSP to display
this
collection using the Struts custom tag library Struts-Logic.
Here is the JSP source:

<!-- InvoiceList.jsp -->
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<%@ page language="java" contentType="text/html" %>
<%@ page import="com.leescarpet.claimautomation.OrderHistoryBean" %>

<%@ taglib uri="/Web-inf/struts-logic.tld" prefix="logic" %>
<%@ taglib uri="/Web-inf/struts-html.tld" prefix="html" %>

<html:html>
<HEAD>
<META name="GENERATOR" content="IBM WebSphere Page Designer V3.5.3 for
Windows">
<META http-equiv="Content-Style-Type" content="text/css">
<TITLE>
Invoice Selection
</TITLE>
</HEAD>
<BODY BGCOLOR="#FFFFFF">

<P>
<H1>Select the invoice for the customer filing the claim</H1>

<TABLE>
  <TBODY>
     </TBODY>
</TABLE>

<FORM>

<TABLE>
  <TBODY>
    <TR bgcolor="lightblue">
      <TH width="125">Invoice Number</TH>
      <TH width="89">Invoice Date</TH>
      <TH width="185">Customer</TH>
      <TH width="148">Acknowledgement Number</TH>
      <TH width="114">Acknowledgement Date</TH>
    </TR>
    <%

//**************************************************************************
************
        //  Set up alternating row colors

//**************************************************************************
************
      String bgColor = "silver";
    %>
    <logic:iterate id="ohl" name="ohl"
type="com.leescarpet.claimsautomation.OrderHeaderBean" scope="request"
>
    <%

//**************************************************************************
************
        //  Set up alternating row colors

//**************************************************************************
************
      bgColor = bgColor.equals("silver")? "white" : "silver";
    %>

    <TR bgcolor = "<%= bgColor %>" >
      <TD width="125"><jsp:getProperty name="ohl"
property="invoiceNumber"/></TD>
      <TD width="89"><jsp:getProperty name="ohl"
property="invoiceMonth"/></TD>
      <TD width="185"><jsp:getProperty name="ohl"

    </TR>
   </logic:iterate>
  </TBODY>
</TABLE>
</FORM>
</BODY>
</html:html>



When I try to run this application in the Websphere test environment, I
get
this error:

Unhandled error! You might want to consider having an error page to
report
such errors more gracefully
com.sun.jsp.JspException: "Directive: Invalid attribute, prefix"
        java.lang.Throwable(java.lang.String)
        java.lang.Exception(java.lang.String).....

The error messag indicates there is someing wrong with the tag library
directive but I don't see it.  I have the struts-logic.tld file in the
web-inf directory of the test environment and have modified the
defaultapp
xml document by adding this:


   <taglib>
       <taglib-uri>/Web-inf/struts-logic.tld</taglib-uri>
       <taglib-location>/Web-inf/struts-logic.tld</taglib-location>
   </taglib>

Any suggestions???
