Subject RE: struts: JSP expression not evaluated

No, you will need to use single quotes for it to work properly.  You should
also look at the <html:link> documentation for better ways of handling this
instead of using scriptlets (<%%>).

| Subject: struts: JSP expression not evaluated
| 
| Hi!
| 
| I do have a very weird problem which I don't even know struts or jasper to
| address to so I post it to both mailing lists.
| 
| Below is a small piece of JSP code, the struts <html:link> tag contains an
| JSP expression in the href attribute which is not evaluated, i.e. the
| actuall link contains the expression just as it is printed in the source
| code below as *string*. Please note that pre-building a Java String
| containing the complete href link and putting that string expression into
| the tag's attribute does work just well.
| 
| This does only apply to struts' <html:link> tag; <a> works just as it
| should!
| 
| <%@ page language="java" %>
| <%@ page contentType="text/html;charset=WINDOWS-1252"%>
| 
| <%@ taglib uri='/WEB-INF/struts-html.tld' prefix='html' %>
| 
| <!DOCTYPE HTML PUBLIC "-//w3c//dtd html 4.0 transitional//en">
| <html>
|         <head>
|                 <title>Test</title>
|         </head>
|     <body>
| <%
|                 int var = 1;
| %>
| 
|                 <!-- the link won't read "blah.do?arg=1 -->
|                 <html:link href="blah.do?arg=<%=var%>">
|                         Link
|                 </html:link>
|         </body>
| </html>
| 
| This works:
| 
| 
| <%
|     int var = 1;
|     String href = "blah.do?arg=" + var;
| %>
|     <html:link href="<%=href%>">
| 
| 
| Can't I see the woods for the trees or is this a bug?
| 
| Timo
