We need to invoke a command line utility and read the output/error from a stateless session bean. Will there be any problems if we use Runtime.getRuntime().exec(command) to invoke the command line utility. Please advise.

other than it being relatively slow,
i don't think doing it in EJB would be any different than doing it in plain java

...except that EJB containers are not supposed to permit spawning of threads or processes. Most will disallow it, although a few do allow it. It will depend upon the container you are running in and the security tolerance it has. The fact that a thread is being spawned from an EJB will not affect performance, though.
