1.1, you have to use JSTL 1.0. For a quick sanity check, what do you get with
the following:
I'am using the JSP 2.0 Container Tomcat 5.0.14
<h1>JSTL: <c:out value="${lvform.map.method}"/></h1> <h1>Struts: <bean:write name="lvform" property="method"/></h1>
The Struts-Tags work, but not the JSTL-Tags!
If you really are using a JSP 2.0 container, you can also try:
<h1>JSP: ${lvform.map.method}</h1>
Also make sure you're using a Servlet 2.4 deployment descriptor:
<web-app xmlns="http://java.sun.com/xml/ns/j2ee";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd";
version="2.4">
...
</web-app>
Since I change the deployment discriptor, there is a exception in all JSTL Tags.

Quoting Alexander Kirsch <[EMAIL PROTECTED]>:
Hallo all,
I have some problems with the JSTL 1.1 (From SUN jwsdp 1.3) Tags together
with
Struts 1.1 DynaValidatorForms.
I have defined the following DynaValidatorForm:
<form-bean name="lvForm" type="org.apache.struts.validator.DynaValidatorForm"> ... <form-property name="method" type="java.lang.String"/> ... </form-bean>
The Form is populated by an Action:
public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) { DynaValidatorForm lvform = (DynaValidatorForm) form; ... lvform.set("method", "add"); ... request.setAttribute(mapping.getAttribute(), lvform); return mapping.findForward("continue"); }
After this the Fields in the Form-JSP are filled correct.
Depending on what method I use I want to output different messages.
For this I tried to use these JSTL-Tags:
<c:choose>
<c:when test="${lvForm.map.method == 'update'}">
<h1><bean:message key="lvform.update"/></h1>
</c:when>
<c:when test="${lvForm.map.method == 'delete'}">
<h1><bean:message key="lvform.delete"/></h1>
</c:when>
<c:otherwise>
<h1><bean:message key="lvform.add"/></h1> </c:otherwise> </c:choose>
But I allways run into the otherwise tree.
I also tries this without success:
<c:when test="${lvForm.map['method'] == 'update'}"> <h1><bean:message key="lvform.update"/></h1> </c:when>
So I hope that anybody can help me to solve this problem.
Kind Regards and thank you very much
Alexander Kirsch
