Jabber

• Jabber is best known as "the Linux of instant
  messaging" -- an open, secure, ad-free
  alternative to consumer IM services like AIM,
  ICQ, MSN, and Yahoo. Under the hood, Jabber is a
  set of streaming XML protocols and technologies
  that enable any two entities on the Internet to
  exchange messages, presence, and other structured
  information in close to real time.

Openfire

• Openfire (formerly Wildfire) and Spark use the
  open XMPP protocol (also called "Jabber"), the
  only broadly-adopted instant messaging protocol
  and an approved standard by the IETF. With many
  server implementations and dozens of clients,
  it's also the only protocol with proven
  interoperability. The XMPP protocol is supported
  and continually enhanced by the active XMPP
  Software Foundation community.

DWR

• Direct web Remoting (DWR) allows code in a web
  browser to use Java functions running on a web
  server as if they were in the browser.

DWR Techniques

• Polling
• At regular and frequent intervals, the browser
  sends requests to the server to see if the page
  has been updated.
• Comet
• After a request has been received from the
  browser, the server keeps the reply open so that
  it can pass down information when it arrives.
  This is also known as a long-lived HTTP
  connection.
• Piggyback
• When the server has an update to send, it waits
  for the browser to make a request and then sends
  the update in addition to the requested
  information.
