How to pass the javascript variable value to a jsp

Question

Hi
I am trying to set a javascript variable with onClick event of a radio button in jsp
and I am assigning this variable to a hidden property in JSP whic has the corresponding getter an setter method in form.
But I am not able to retrtieve the value assigned in either form/action .can any body help me in this:
The code is
<script language="javascript">
var jais="";
     function setValue(val)
          jais=val;
     document.o.value=jais;
</script>
     <html:hidden property="o" value=""/>
<input type=radio name="1"
                                        value="xyz"
                                                                      onclick="setValue('XYZ')" >
                                        ABC                                        
and in the correspoding form bean I have
private String o_val =null;
public String geto()
return o_val;
public void seto(String strs)
o_val=strs;
In the action I am trying to access
by
1)String j=((form name)form.geto();
2)String j=request.getParameter("o")
but with both of them I am getting the value null
Thanks in Advance

You need to set the value of the hidden field in your function.
Setting an unrelated variable will not help.
function setValue(val)
document.forms[0].o.value = val;
also your get/set methods should be getO() and setO().
