how to pass query string when user click on hyperlink text

Hi,

In my JSP page i have hyper text link. Below that link i will have 3 radio buttons. When user click on the hyper link i want pass the value of selected radio button as a query sting with the URL i mention at <a href="url"> tag.

Here is my code but it's not working, i am getting envType value as null

<BODY>
<%
String envtype = request.getParameter("envType");
%>
<TABLE width=600 BORDER=0>

<TR>
<TD><a href="/iaInformation/index.do?envType=<%=envtype%>" ><bean:message key="mwr.link.msg.whows.rpt" /></a></TD>
</TR>

<TR>
<TD class='normal'><input TYPE="radio" NAME="envType" VALUE="T" checked>Test Environment (T01, T02, T03, T04)</TD>
</TR>
<TR>
<TD class='normal'><input TYPE="radio" NAME="envType" VALUE="Q" >QA Environment (Q01)</TD>
</TR>
<TR>
<TD class='normal'><input TYPE="radio" NAME="envType" VALUE="P" >Production Environment (P01)</TD>
</TR>
</TABLE>

</BODY>

Please correct me if i am doing wrong.
I appreciate ur help!

You could use a HTML form to submit data to server. Or maybe you could use JavaScript to create the URL.

>Please correct me if i am doing wrong.
You are trying to use JSP on the client side. JSP is at the server and JavaScript is in the browser.

For this to work, you need to have /iaInformation/index.do defined in your struts config and working.

<BODY>
<%
String envtype = request.getParameter("envType");
%>
<TABLE width=600 BORDER=0>
<html:form action="/iaInformation/index.do" method="GET" >
<TR>
<TD>
<bean:message key="mwr.link.msg.whows.rpt" /></a></TD>
</TR>

<TR>
<TD class='normal'><input TYPE="radio" NAME="envType" VALUE="T" checked>Test Environment (T01, T02, T03, T04)</TD>
</TR>
<TR>
<TD class='normal'><input TYPE="radio" NAME="envType" VALUE="Q" >QA Environment (Q01)</TD>
</TR>
<TR>
<TD class='normal'><input TYPE="radio" NAME="envType" VALUE="P" >Production Environment (P01)</TD>
</TR>
</TABLE>
</html:form>
</BODY

I am increasing points, if it is difficult.

instead of
><a href="/iaInformation/index.do?envType=<%=envtype%>" ><bean:message key="mwr.link.msg.whows.rpt" /></a>
you could use something like
><a href="#" onclick="this.href = '/iaInformation/index.do?envType=' + document.formname.envType.value;"><bean:message key="mwr.link.msg.whows.rpt" /></a>
I did not check my javascript code. You might have change the way I access envType's value. rrz

>var envType = "T";
maybe I should have used
var envType = document.index.envType[0].value;

rrz.. it seams javascript is working fine. It's picking up right envType value.
But some how when i click on the link, it's not calling /iaInformation/index.do link.
I guess there is some thing wrong in the following statement

document.links[0].href

sorry rrz...
It's working fine. Actually i have links in my page, so when i changed

document.links[0].href to document.links[1].href
it's working fine.

Thanks
