Dear Wowza, I am Flash/Java programmer working on platform for audio/video/text chat. We have few wowza application running on server, each one with its own custom made module. I am curious if there is any way how i can **update custom module classes (jar file inside lib/ folder) without need to restart Wowza** media server. After i did few tests, it looks like Wowza red this classes when server was started and didn’t get any changes of jar files later. Thanks for help. ---

We have no short term an to add support for this. Charlie ---

You’re right, that’s the only way. You have to restart Wowza if you add or update jar files in lib folder. Richard ---

In is greate idea - implement class loading scheme and hot-deploy like in jakarta-tomcat, if it possible. ---

I really don’t understand why Wowza doesn’t offer something like hot deploy or specific module reloading. I mean, we are talking about production environments, right? There it’s a must have to be accessible 24/7. In the past I had no problems with restarting the server even several times a day. But now we have multiple instances of applications running around the clock every day so it’s pretty hard to find a gap where you can easily restart the server without introducing trouble to anyone. That’s why I currently think about a solution where a specific monitoring application waits for low server activity so the update and restart job can be done automatically. Robin ---

Really thank you Richard! You just saved me few hours of investigation. ---

Hi there, It’s been a few years now since this has been addressed, and I’m finding it would be extremely useful if this were either possible by now, or at least on “the agenda list” . My scenario - I need to load in custom applications from scratch that use a custom wowza module (.jar file) on a per-application basis without reloading the server entirely in production - in turn causing all the other currently running applications to be rebooted from scratch and lose service to the existing users using those other already existing and running applications. A graceful refresh of “reloading” any new modules would be indeed awesome and really help my life as of right now. Please let me know where you guys stand on this 🙂 Thanks. ---

> hi, > > I have not heard of any plan to change this. > > Richard Thanks Richard. I’m sure you have some brilliant people over there that can pull it off. If you so happen to speak with a lead developer there in the near future and you so happen to remember this topic, do you mind dropping the idea by him again if you don’t mind 🙂 At least to put the idea in his head again so maybe he ponders it. It’s hard having to disconnect the whole service and active users disconnect, especially in a video conference or something of that nature, to load in new custom modules.
