about sending request

hello
I am doing one appliocation for sending one messege from my tomcat to other tomcat in LAN.
can i do this ?
please give me some hint .

Sure. HTTP would seem simplest since both servers are obviously equipped to handle it, but many other options exist: Mail, JMS, shared file system, database, sockets, web service, ...

can you tell me the link from where i'll get these details with examples ?
Through webservice how we can do ?

Unless you have specific reasons to use WS, I'd resort to HTTP or raw sockets. Code examples for both can be found here. The Sun Java Tutorial also has an extensive chapter on networking.

Thanks a lot Ulf.

Through mail how can we do this ?
My application is client-server(request-response) type.
if suppose there 3 machines in network ,then they should communicate with each other ,having inbox(mail saved ) on their machines.

Obviously, there would need to be a mail server that all machines can access. The client access to that server can be handled using the JavaMail API.

I think that HTTP would be far easier to implement, though, and have other advantages (like synchronicity).

There is the Java Mail API for mail communication, but if you need to communicate among two servers (or a client and a server), then I think that HTTP is the best way

[edit]
Well Ulf said it before me

although his post was not visible the time I posted.And since we both are saying the same thing then it must be right

Through http get & post methods we have to do it or other methods are used.

I'm not sure what you are saying/asking here.
Was there something in an earlier post that you didn't understand?

There are many methods, like Ulf and the others have pointed out. You need to decide which one you want. What is it that you are trying to send ?
