JSTL

[Dennis Dahn]

Hello,

I would like to transfer code from JSP to JSTL but have some problems,
especially in the following code:

<%
if (request.getParameter(ISBN) != null){
book= katalog.getBuch(request.getParameter(ISBN));
%>

in jstl i thought it would be like this:

<c:if test="${param.isbn != null}">
<c:set var="buch" value="${katalog.buch}>
<caram name="isbn"/>
</c:set>
<cut value="${buch.buchTitel}"/>
</c:if>

but there is just an error. So how can I declare the parameter ISBN?

Thanks in advance!

Regards,
Dennis

if (request.getParameter(ISBN) != null){
book= katalog.getBuch(request.getParameter(ISBN));
*snip*

in jstl i thought it would be like this:
*snip*

but there is just an error. So how can I declare the parameter ISBN?

I think the problem might just be one of case: if the form field is ISBN all
caps, then you want ${param.ISBN}, not ${param.isbn}. JSTL property names
are case-sensitive.
