Hi,
In this case you will have to share the data between the processes.
A simple and easy solution would be to use http://hazelcast.com/, for
example.

Does it matter that foo will not be running on a server? It will be running
as a standalone on the machine, unaware of tomcat basically.

Communicate means something happens that the daemon is monitoring, so thus
the daemon sends a message to the websocket server running on the webapp,
so that message can get relayed to the webpage from the server and the
daemon will also need to get messages from the webapp. It will then be two

http://enable-cors.org/ should be enough to allow external clients.

Read in the web about it.

Yes we are trying to portable, well the socket is the last resort. We are
trying to avoid it until now but will go that way if we have to if there is
no other way. Mostly due to the data coming in and out writing our own

Any IPC that you have to write from scratch is going have a not
insignificant level of complexity whether it's raw sockets, pipes, http,
whatever. Since it sounds like you can't introduce any additional
software packages, you might want to consider using RMI (see the
java.rmi package). At least

That seems like the way to go. IT avoids us having to write our own
protocols and everything and instead just code the logic for what action to
take when a certain message is received.

Couldn't you have the daemon write to a database, and have the web app
read from the database?
Then you could pass whatever message you wanted as a string?
