html link with params

[Vadiraj Deshpande]

Hi all,
I'm feeling great by logging into javaranch after
a gap of 2 yrs. I was a regular visiter when i was preparing for my SCJP.
Here's my query:
How do i pass params along with link?
i tried this:
<html:link href="/web-struts/navigator.do?action=edit_fra&franchiseeName=<%=theVO.getFranchiseeId() %>" >
<%=theVO.getFranchiseeName()%>
</html:link>
its not working as expected. mainly not substituting the value.
Any ans?
Thanks,

Well that's a problem with your code then, since that link tag looks fine. I take it you mean that the parameter is null when it arrives back at the server?

Hi Adam,
Well the problem is : The inside scriptlet is not executing.
The code:
<html:link href="/web-struts/navigator.do?action=edit_fra&fra_id=<%=theVO.getFranchiseeId()%>" >
<%=theVO.getFranchiseeName()%>
</html:link>
The URI when the page is executed:
/web-struts/navigator.do?action=edit_fra&fra_id=<%=theVO.getFranchiseeId()%>
And the value of franchiseeid is not null.
Thnx,
vadi

You could do something like the following:

<%
Map m = new HashMap();
m.put("action","edit_fra");
m.put("fra_id",theVO.getFranchiseeId());
pageContext.setAttribute("map", m);
%>
<html:link page="navigator.do" name="map">
  <bean:write name="theVO" property="franchiseName"/>
</html:link>

Personally I would prefer to put the scriptlet code in the Action and have it place the Map into the request before forwarding to the jsp. I would also have the Action place 'theVO' into the proper scope and access it that way as opposed to using a <jsp:useBean> which it looks like you are doing. In addition, I would also use <bean:write> instead of the scriptlet for getFranchiseName().
In any case, I suggest you check out the taglib documentation for further clarification. Hope this helps.

Hi Jason,
Thanks a lot for your help. Your solution was excellent. I'm getting a collection of VO's from the Action and getting individual VO's and creating the link with them in the jsp. I'm not using any <jsp:useBean>.
Any further improvements possible?
Thnx again,
vadi

Ahh.. okay I get it. That's the body of some iteration (using <logic:iterate> perhaps?). Anyway, glad that worked for you, best of luck on your project.
