The use of the term "Daemon Process" in java

can we use it or not..???coz in my design
documentation I have mentioned as daemon process which
consumes jms message but been restricted to use the
term daemon process saying that it no way belong to
java and it is specific to unix.

First sounds like some confusion on your co-workers part (or you didn't relay the entire conversation.)

The Thread class in java has the setDaemon() method. So java certainly has something called 'daemon'.

but in common sense daemon is the generic term any
process which runs through lifetime of an application
can be said to be daemon process and what is the
restriction of using the common terminology...??????
and why do you look narrow with respect to UNIX...???

Even though it exists in java doesn't mean that you are referring to it correctly. It isn't even clear that you need to refer to it.

Maybe you have a process that runs when the server starts up. In your documention you might generically refer to this (using the phrase I used) and then specifically say "for example a 'service' on a Windows OS".

If, on the other hand, you are specifically referring to a thread and not a process, then there are two possible explainations.
1. You really do have a daemon thread and someone else doesn't know what they are talking about.
2. You don't have a daemon thread, but merely have a regular thread. A daemon thread is typically going to be one that does somethig independent of other threads and entirely in the background. Thus a GUI thread is not a daemon thread. Nor is a socket handler thread. But the garbage collector thread is a daemon.
