Answer Posted / venkat

by default every servlet is not Thread safe.

if we want to make Thread safe use these statements

1) use SingleThreadModel interface . but this interface is
deprecated in servlet 2.5 specification

2) use synchronized methods and blocks

for example
=========
use synchronized method
=======================


public synchronized void service(ServletRequest
request,ServletResponse response) throws
ServletException,IOException
{
.........
.......
}

use synchronized block
========================


public void service(ServletRequest request,ServletResponse
response) throws ServletException,IOException
{
synchronized(this)
{
.........
.......
}
}
