Can i make my own jabber server.So
that if i run my website xyz then
people should be be able to get theri
jabber id from my website by
registering on my website.
It depends on what kind of hosting you have. I think you should at least have VPS hosting to install the software. Basic hosting for a couple of bucks does not allow you to run jabber server.
Is there any open source implementation of jabber server that i can use?
I myself really like lua's prosody. It is easy to install / configure
