Re: HTTP session communication between VMs

MessageHi,

You can try ServletContext.getContext(...) to share info from one web app to
another web app.

Things to remember :
    i)    Both applications must be running on the same JVM
    ii)    Your web/app container should support 'cross-context'
    iii)   The other web app is considered to be already loaded.
            In other words, one of it's web resources got already invoked by
some way (either by direct call or by a Startup-Servlet)
            so that it's web context got already established.

  thanks for the reply
  what if i have different HTTP session of two different applications
packaged on different EAR file but on the same VM.
  would i be able to communicate between sessions using a context listener?

    As far as I know, you can't do this. i mean inter VM HTTP session is not
possible. Possible solution for this is to take the intermediate approach...

       Use the database table to access the shared information from
servlets/JSp/Bean running both VMs. in this case the point of conatct will
be the database table.

    Thanks

      Hi all;

      I need to solve a problem where one HTTP session on Machine A notifies
      another HTTP session on machine B that 'something happened'.

      I cant seem to find a good solution for this.
      Any suggestions?
      Thanks.
