Pass Javascript variable to java in jsp

Questions:

After getting the user_name on client side using the below code :

<script type="text/javascript">
        var WinNetwork = new ActiveXObject("WScript.Network");
        var user_name = WinNetwork.UserName;
</script>

I was blocked how to pass the value of the variable “user_name” to the java code below,in order to test if this user exists on an oracle table :

<%
    try {           
        ResultSet rs1 = stmt
                .executeQuery("select * from utilisateur where upper(login) like upper('" + user_c + "')");

        if (!rs1.next()) {
            int i6 = stmt.executeUpdate("insert into utilisateur(login) values('" + user_c + "')");
        }
    }
    catch (Exception e) {
        System.out.print(e);
        e.printStackTrace();
    }
%>
