hi please help me with my problem... i am new to this...

can a java script call a jsp?

i have a script like this...

function getTargetTable(pCluster, pYear){
// i want the pCluster and pYear parameter to be stored
// in strFilter so that i can use it when a set the property
// of the bean...
<% String strFilter = pCluster+","+pYear; %>
<jsp:setProperty name="targetSettingBean" property="targetTable" value="<%= strWhere %>" />
}

is that possible? if not can u give me other alternatives?

thank you very much in advance

:confused:

I am not sure if this is what you are after......

basic idea to change a variable/paramter in an Applet/Object

you can use the param tag inside of an applet/object tag

<applet code="Hello.class" width.....blah... id="TheApplet">
<parm name="display" value="This is some text">
</applet>

THe basic idea with the javascript would be

<script>
function displayitem(){
var applet = document.getElementById("AppletID");
applet.AppletVariable = "Your String";
applet.repaint();
}

thank you for your help, but i'm not using an applet... sorry if i can't explain clearly what i want to do but here is the whole code of my jsp...

basically what i want to do is to call the javascript passing the two parameters, and the parameters which i pass will be used to set a property of the bean(jsp)... how can i do it?

<%@ page contentType="text/html;charset=WINDOWS-1252"%>

<jsp:useBean id="targetSettingBean" class="ams.inquiry.TargetSettingBean" />

<HTML>
<HEAD>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=WINDOWS-1252">
<title>Target Setting</title>
<%@ include file="header.jsp" %>

-- and here is my problem --
<SCRIPT LANGUAGE="JavaScript">
function getTable(pCluster,pTYear){
<%String strWhere = "01,2002";%>
<jsp:setProperty name="targetSettingBean" property="targetTable" value="<%= strWhere %>" />
}
</SCRIPT>

</HEAD>

<BODY topmargin="0" leftmargin="0">

No, you can not pass variables between your jsp / javascript,
The only way to go from JavaSCript to jsp page will be using the HTTP Request,i.e submitting the form or calling a jsp page with values appended to the url.
The other way to get this done might be use of applet.
