Beginners JSTL Question

[Gerard Garrigan <ge...@precisionsoftware.com>]

Hello,

I've just started using JSTL and was trying out some sample code. I
wrote a page in html where the user checks boxes. The jsp page then
lists the boxes the user checked or prints a message if nothing was
checked. 

Here's my jsp code:
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
<c:choose>
<c:when test="${not empty paramValues.feedback}">
You described our customer service as
<ul>
<c:forEach items="${paramValues.feedback}" var="adj">
<c:choose>
<c:when test="${adj == 'satisfactory'}">
<font size="+2">
</c:when>
<c:otherwise>
<font size="-2">
</c:otherwise>
</c:choose>
<li><c:out value="${adj}"/></li>
</font>
</c:forEach>
</c:when>
<c:otherwise>
You didn't choose any feedback checkboxes.
</c:otherwise>
</c:choose>


When I run this in Tomcat I get the following error:

org.apache.jasper.JasperException: Unable to compile class for JSP

Generated servlet error:
E:\Program Files\Apache Software Foundation\Tomcat
5.0\work\Catalina\localhost\JSTLSample1\org\apache\jsp\checkbox_jsp.java
:52: 'try' without 'catch' or 'finally'
try {
^


Generated servlet error:
E:\Program Files\Apache Software Foundation\Tomcat
5.0\work\Catalina\localhost\JSTLSample1\org\apache\jsp\checkbox_jsp.java
:72: 'else' without 'if'
} else {
^


Generated servlet error:
E:\Program Files\Apache Software Foundation\Tomcat
5.0\work\Catalina\localhost\JSTLSample1\org\apache\jsp\checkbox_jsp.java
:78: illegal start of type
} catch (Throwable t) {
^


Generated servlet error:
E:\Program Files\Apache Software Foundation\Tomcat
5.0\work\Catalina\localhost\JSTLSample1\org\apache\jsp\checkbox_jsp.java
:88: <identifier> expected
}

etc.

Could anyone please help me out with where I'm going wrong?

Many thanks,

Ger

Since you're on Tomcat 5.x, why not use JSTL 1.1? More on that here:

http://wiki.apache.org/jakarta-taglibs/FrequentlyAskedQuestions

Please ask usage questions on the user list.
