Can anyone please share their experience of invoking unix scripts from a Java EE env, either servlet or EJBs? Note that these scripts are to be invoked for real time processing and not offline processing.

Spawning processes from a Java EE container is probably not the right way to this.
If these are shell scripts they will not be portable.
If you want to use transaction support, the scripts could be rewritten as Jobs using Quartz Scheduler.
This is more likely the Java EE way to do things like that.
EDIT:With your requirements added in the commented this should work

please note that if you use scripts and/or pipes (no native executables) you must include the shell to invoke the command (and setup pipes)
