File “/struts-tags” not found in Struts 1.3

Question

I wrote a conditional if else tag inside a logic:iterate in jsp as below:-

<s:if test="%{#status=='Scheduling'}">
<td><input type="button" name="Save" enabled="enabled" value="View Log" class="Button" onclick="javascript:update('<bean:write  name="test" property="listName" />','<bean:write name="test" property="testType" />',<bean:write  name="test" property="status" />,this.value)"></td>
</s:if>

<s:elseif test="%{#status=='Running'}">
<td><input type="button" name="Save" enabled="enabled" value="View Log" class="Button" onclick="javascript:update('<bean:write  name="test" property="listName" />','<bean:write name="test" property="testType" />',<bean:write  name="test" property="status" />,this.value)"></td>                
</s:elseif>

<s:else>
<td><input type="button" name="Save" disabled="disabled" value="View Log" class="Button" onclick="javascript:update('<bean:write  name="test" property="listName" />','<bean:write name="test" property="testType" />',<bean:write  name="test" property="status" />,this.value)"></td>                   
</s:else> 

I defined a <%@taglib prefix="s" uri="/struts-tags" %> in the beginning of the jsp file as shown below:-

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<%@taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@taglib prefix="s" uri="/struts-tags" %> 

When I am opening the jsp file i am getting the following errors. Could you help me in resolving this?

Answer 1

You are mixing the Struts 1.3 tags with the Struts 2 tags. In order for your taglib declaration <%@ taglib prefix="s" uri="/struts-tags" %> to compile, you must include the struts2-core-2.1.6.jar (latest jar at the time of writing) in your WEB-INF\lib folder, Struts 2 struts-tags.tld is found under (struts2-core-2.1.6.jar\META-INF\struts-tags.tld).

Bear in mind that Struts 2 is never backward compatible with Struts 1 as it's a completely new architecture Apache has taken new direction from Struts 1.

I suggest using JSTL instead of using Struts 2 taglib definitions as Struts 1.3 works well with JSTL.

Answer 2

in your deployment descriptor, that is web.xml, you should have something like the following declared. (remember to have the tld files in your that taglib-location)

   <jsp-config>
     <taglib>
       <taglib-uri>/WEB-INF/struts-html.tld</taglib-uri>
       <taglib-location>/WEB-INF/tlds/struts-html.tld</taglib-location>
     </taglib>
   </jsp-config>
