Hi, I am trying to evaluate JMS software, and I've downloaded Sun's Message Queue 3.0.1sp2 Platform Edition. The problem I have is that while all the topics and durable subscriptions I'm creating get persisted, the messages do not! I'm using the file-base persistance, and I've set imq.persist.file.sync.enabled=true and imq.persist.file.message.cleanup=true . As both a Windows service or running on RedHat Linux, the messages don't persist when I shut the queue down; On Windows, some empty files with numbers for filenames are there, but on Linux nothing is ever written to the messages directory in the var tree. Any ideas? Yes, my user does have write permission in the directory. Thanks, Zac    More>>

Turns out everything is working great; I was setting the message deliver mode to NON_PERSISTANT - a great way to avoid having things persist.

D'oh!
