I would do somthing like the following:
<TABLE border="0">
<c:forEach items="${contacts}" var="contact">
<TR>
<TD>${contact.name}</TD>
<TD>${contact.number}</TD>
<TD><c:url var="url" scope="session" value="/do/modifyContact">
<c:param name="ID" value="${contact.id}"/></c:url>
<a href="<c:out value='${url}'/>">Modify</a>
</c:forEach>
The action modifyContact should load the contact with the specified id, "ID"
is available by
String ID = request.getParameter("ID");
The action then stores the contact in the request scope:
request.setAttribute("contact",contact);
then forward to the jsp:
name:${contact.name} etc...
Hope that helps,
Daniel.
