Subject RE: use html:link pass two param
Date Sat, 01 Nov 2003 16:53:35 GMT
Not sure about the error, but you aren't referencing the bean properties
properly.


<jsp:useBean id="cus" class="java.util.HashMap"/>
 ...
 <c:set target="${cus}" property="cid" 
        value="list.id"/>
              ^^^^^^^^^

...and...

 <c:set target="${cus}" property="company"
        value="list.company"/>
              ^^^^^^^^^^^^^

When referencing dynamic properties with JSTL, be sure to use ${}
syntax.

Try doing this:  value="${list.id}"
