Hello all,

Both ServletConfig & ServletContext have the following methods:

Hello all,

I have a situation in which i need to redirect a request from a server to another server. Like i have a link 'Application2' which takes the user on one application to 'Application2'. How can do that in the following cases:

1. When the Source is an HTTP server and destination is an HTTP server too
2. When the Source is an HTTP server and destination is an HTTPS server
3. When the Source is an HTTPS server and destination is an HTTP server
4. When the Source is an HTTPS server and destination is an HTTPS server too

What are the configurations to be done in each of the cases? If the configuration is specific to the app server, then please explain in terms of Tomcat servlet engine

Hello all,

Suppose i have a table "Employee".
I insert Employee1 into Employee table.
Then I insert Employee2 into Employee table.
Now if i do "Select * from Employee", will i always get Employee1 followed by Employee2. In other words will the order be always Employee1 and then Employee2. Is there any change that i may get Employee2 and then Employee1?

Hello,

I invoke a servlet which inturn invokes a few DB2 sps to get the job done.
Each of the DB2 sps takes approximately 20 mins to complete ( There is some complex logic in each). In the midst of this processing is there any possibility of session expiring? I mean, assume that my session time out is 30 mins. And if my servlet takes 45 mins to execute, will my session time out in the middle of processing? If yes, then how do i prevent this from hapanning?

Hello,

Suppose i have 3 threads t1, t2, t3.
To get a multithreaded behavioyur can i just invoke the start() methods on each of the threads one after the other ( assuming i have written code in the run method to do the necessary task).
Or do i have to esnuer that each thread sleeps for a while so that other threads will take control and not get starved.
In other words is it essentila that each thread sleep for a while to geta multithreaded behaviour?

Hello all,

I have a jsp ( A.jsp). On click of a button 'Save' i invoke a servlet (ServletA) to get some operation done. after the operation is done i invoke 'B.jsp' using response.sendRedirect("/gem/B.jsp");
This works fine.
Actually the operation done ServletA is very time consuming. Thus as long as the user doesnt close 'A.jsp' browser window while the ServletA is executing, it work fine.
But if the user close the 'A.jsp' window, everything works fine except that the 'B.jsp' is not shown ie. response.sendRedirect("/gem/B.jsp") doent work anymore. How do i ensure that 'B.jsp' is shown even if 'A.jsp' browser window is closed.
