Ok, good to know, thanks for the clarification From: Imesh Gunaratne [mailto:[email protected]] Sent: Friday, January 30, 2015 7:25 PM To: dev Subject: Re: DISCUSS: RE: Are we still supporting java agent?
Hi Martin, That's great, we will review the changes in Java Cartridge Agent (JCA) and get back to you. Thanks for bringing this up. At the moment there are two entities that represent an application; applicaiton definition and applicaiton runtime. Application defintion is the entity that we use when creating an application and application runtime is the entity which gets created after passing the application definition. Application runtime may change dynamically according to the scaling requirements. For now application definition state is only set to "Created" and "Deployed". However if we query application runtime we can see its runtime state.

I took a stab at the JCA and got it to work. I pushed my changes to the master, please review the changes in case I missed something. So far I have only tested with a simple scenario. I attached the log files (both cartridge agent log, wso2carbon.log), and the cartridge goes into active state. What puzzles me is that I can see in the logs that the application “ACTIVE” event is published, but when I check the application state with the stratos cli it still shows “Deployed” state, not sure what is missing and how the application state is updated.

Hi, Have spoken few users and they still using Java cartridge agent and need some time to migrate into python cartridge agent. Considering that, IMO will support java cartridge agent in 4.1.0 and will obsolete it with next release. thanks On Sat, Jan 24, 2015 at 10:06 AM, Martin Eppel (meppel) <[email protected]<mailto:[email protected]>> wrote: Thanks for the heads up Regards Martin From: Imesh Gunaratne [mailto:[email protected]<mailto:[email protected]>] Sent: Friday, January 23, 2015 8:29 PM To: dev Subject: Re: DISCUSS: RE: Are we still supporting java agent? Hi Martin, I assume no one has tried Java based Cartridge Agent since we started using the Python Cartridge Agent. However we have updated it with the recent changes we did for messaging, otherwise the build will break. No, MQTT support is implemented in messaging component so any other Java component that uses messaging will automatically get it, which means Java based Cartridge Agent already has MQTT support. We might need to check following: - Payload parameters which were updated recently - Event listener logic related to Artifact Distribution - Puppet module of Java based Cartridge Agent Thanks On Sat, Jan 24, 2015 at 12:08 AM, Martin Eppel (meppel) <[email protected]<mailto:[email protected]>> wrote: Bringing this topic up again. We do have some requirements to, at least temporarily, maintain a functioning java based cartridge agent. Has any work gone into the java based cartridge agent since the last discussion? Has someone else tried if it still works ? Getting it back to work, where would you expect the issues ? For example, I would expect to have to add support for the mqtt client ? Any other things to watch out ?

Hi, +1 for comment java agent from components/pom.xml. Thanks !

Since we are not using java agent, people will make changes to java agent just for the sake of compiling. No one is testing java agent's functionally. If we continue to do this, java agent will be nothing but a garbage in future. At least, we should comment the java agent from components/pom.xml so that we can avoid build failures and we can keep a stable java agent. We all know that we can always go back and checkout a tag/commit and get the java agent :) However, it is just my thought.
