You probably can't "pass the object"
and you probably don't need to.
Think about the systems that are running your code:
* servlet runner JVM/web server is executing the servlet
your JSP compiled into, connect to via HTTP requests/responses...
* web browser with javaScript interpreter running the javaSCript
and (maybe, maybe not activated and maybe soon not there)
JVM is running the java code and accessing java objects from
javaScript.
Do you really want to send a serialized
object or handle to a remote object
between your servlet runner's JVM, via the web server, to the
(maybe not there) JVM inside your web browser just so a javaScript
function can get access to a bunch of strings?
Why don't you just send the string data inside the properities object?
Cheers, Andy

Subject: how to call javascript function and pass class object to it i n
JSP?
Hi,
this is the sample code I try to pass a variable to javascript function
from
jsp. it works.
but if I try to pass Properties object prop to that function, it won't
work.
I like to know to pass the object?
<%@page import="java.util.*" %>
<% // the page is forwarded from another jsp page which
// set request.setAttribute("prop",value).
Properties prop = new Properties();
prop = (Properties)request.getAttribute("prop");
String name = prop.getProperty("name1");
%>
<html>
<head>
<title>MAMSI- Group Eligibility</title>
<script Language="JavaScript">
function go(name1)
{
alert("name=" + name1);
}
</script>
</head>
<body>
<a href="javascript:go('<%=name%>')"> click here to pass property </a>
</body>
</html
