Hi,
i have multiple Submit buttons on myjsp and the correspond to different servlets. could any one advice me how to map them correctly to correct servlet and also to perform the javascript for each(if assigned). below is the code that i used.

<%@page import="java.sql.*"%>
<%@page import="java.lang.*"%>
<%@page import="java.io.*"%>
<%@page language="Java"%>
<html>
<head>
<script type="text/javascript">

function move(){

document.getElementById('tgt1').value = document.getElementById('Allocation').value;
 document.getElementById('Allocation').value="";
 document.getElementById("Send").disabled=true;
 
 
 
}
function UnBlock()
{
    document.getElementById("tgt1").value="";
    document.getElementById("Send").disabled=false;
    document.getElementById("tgt2").style.display="block";
    document.getElementById("Query_but").style.display="block";
   }
function UnBlock_Only(){

document.getElementById("Send").disabled=false;
    document.getElementById("Query").disabled=true;
}
f

</script>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<style type="text/css">
body {
	margin-top: 20px;
	margin-left: 30px;

}
</style>
</head>
<body>

<form name="myform" method="post" action="Serv_Alloc.do">
<%
try {
    String sessname=(String)session.getAttribute("myusername");
    PreparedStatement ps,ps2=null;
    ResultSet rs=null;
    Statement st=null;
    Connection con=null;
    Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
    con = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe", "system", "tiger");
    ps=con.prepareStatement("select DBID from Scope1 where specialist IS Null");
    rs = ps.executeQuery();
    if(rs.next())
    {
       
%>
<input type="text" name="Allocation" size="75" id="Allocation" value="<%=rs.getString("DBID")%>" readonly="readonly">
<%
}
}
catch(Exception e){
out.println(e);
}
%>

Thanks,

*move all scriptlet code to a java class.

Coming to your question:
there are two ways, what i can think of ,

1. call a javascript function by passing a value onclick,
then construct servlet path according to JS function parameter and submit.

2. without javascript, just call a servlet there you get the value of submit button,
now you forward to appropriate servlets.

Thank you Venkataswamy, if you don't mind could you please post a sample code for both the mentioned methods, just the redirecting path is enough, so that, i can get an idea about how to do it.

Thanks,
Rakesh
