Caroline,
Have you tried the following?:
<c:set var="threadBean" value="${requestScope.ThreadBean}" />
<c:set var="threadID_int value="some int value" />
<c:if test="${threadBean.threadID != threadID_int}">
<!-- Do something -->
</c:if>

Subject: Re: Converting Java Code in JSP to JSTL
I pass an object ThreadBean from an action servlet in
a request scope:
request.setAttribute( "ThreadBean", threadBean );
In my JSP, there is no problem and everything works
well if I use scripting element:
<%
ThreadBean threadBean = ( ThreadBean
)request.getAttribute( "ThreadBean" );
%>
I then re-write the above statement to:
<c:set var="threadBean"
value="${requestScope.ThreadBean}" />
when I tried to use the properties of the threadBean:
if ( threadID_int != threadBean.getThreadID() ) {}
I got compilation error "illegal start of expression".
Why JSTL does not work?
