Hi I follwoed the below URLs...
http://tomcat.apache.org/tomcat-5.5-doc/cluster-howto.html

http://tomcat.apache.org/connectors-doc/generic_howto/workers.html
But no luck.. Session is not get replicated..
This is my configuraion

Below is the Tomcat1 server.xml.

For Tomcat2 i had changed the below elements only..
<Server port="9005" shutdown="SHUTDOWN">
<Connector port="9081" maxHttpHeaderSize="8192"
maxThreads="150" minSpareThreads="25" maxSpareThreads="75"

mcastBindAddress="192.168.10.50"
mcastPort="45564"
mcastFrequency="500"
mcastDropTime="3000"/>
Program code..
I had designed a bean and servlet like this..
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.util.*;
import com.bean.SessionCart;
public class SessionStoreServlet extends HttpServlet
{
public synchronized void init (ServletConfig config) throws ServletException
{
super.init();
}
public void doPost (HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
{
StringBuffer HTML = new StringBuffer();
res.setContentType("text/html");
PrintWriter out = res.getWriter();
SessionCart sc;
HttpSession session = req.getSession(true);
sc= new SessionCart();
session.putValue("Cart",sc);
String userName=req.getParameter("loginid");
((SessionCart)session.getValue("Cart")).setName(userName);
out.println("Your account number is " +
((SessionCart)session.getValue("Cart")).getName());
}
}
and Bean is like this..
package com.bean;
public class SimpleBean implements java.io.Serializable {
private String name = null;
private int age = 0;
public SimpleBean() {}
public String getName() {
return name;
}
public void setName(String s) {
name = s;
}
}
HTML like this
<form method="POST" action="servlet/SessionStoreServlet">
<input type="text" name="loginid" size="20"></p>
<input type="password" name="password" size="20"></td>
<td width="50%"><input type="submit" value="Submit" name="B1"></td>
<td width="50%"><input type="reset" value="Reset" name="B2"></td>
I had paste the mod_jk.dll in conf/modules..
What i m trying is
First i started the Apache and then Tomcat1,Tomcat2..
I run the html file in Tomcat1 and the given value is stored in session and
displays the same.
Then stop the Tomcat1..
If i run the same HTML i want to show the session value which is stored in
Tomcat instance1..
But i can not get the old session value..It will start new session only..
Session is not get replicated across Tomcat instances...
Is there is any wrong in my steps?
Replication memebers are added sucessfully in both tomcat instances.. i.e,
replication member messages
are shown in Tomcats but session is not get replicated..
Pls help..
If possible give tested code and server.xml, workers.properties ..
Bcoz no one document is clear abor mod_jk..
I m confused ..
Thanks
