Subsonic Forum

I'm pretty new to subsonic. I'm running Subsonic from my Tomcat 7 server with java 7. I had to do a bunch of manual tweaks to get subsonic to work.

I'm trying to deploy subsonic-tomcar.war to get MusicCabinet running, but I'm not able to deploy it.

From my tomcat7 catalina log:

I'm not sure if I got postgresql up correctly or not. I installed from my package manager.

Any ideas?

Thanks

Does it give the same output if you restart Tomcat? I think that this error is due to Subsonic doesn't close some of it handlers correctly when you hot-deploy a new version, but it doesn't actually have an impact as Tomcat closes them for you. I'd need to look into it a little more though to be sure.

Same output after restarting Tomcat. Do I need to create a folder inside /var for MusicCabinet? I had to create /var/subsonic for subsonic to deploy.

I thought Subsonic did not support tomcat7? Is that not the case with MusicCabinet?

I have it running on Tomcat7 as we speak.. I had to change a few things in the code compared with Subsonic 4.7 to make it compatible though (Tomcat7 is slightly stricter than Tomcat6), but I did that months ago.

The Tomcat war will read your Subsonic settings directory (I think /var/subsonic is the default) to pick up your users etc. You shouldn't need to create a new directory for running it, unless you want parallel installations. You're not running both Subsonic 4.7 and MusicCabinet at the same time, as different wars? That will create a conflict as both of them will try to take a lock on the internal database.

Can you post full Tomcat logs so that I can check them for errors? Thanks.

I modified subsonic.war so it would deploy on Tomcat 7.

I had subsonic.war deployed and was trying to deploy subsonic-tomcat.war (MusicCabinet). I thought that they would both deploy to their own directories. But you're saying that it will use /var/subsonic, so I'll do some testing by undeploying subsonic first.

edit: I was able to run the webapp from within eclipse on my linux box. not sure why I cant deploy it in Tomcat. I'm probably doing something stupid.

edit2: yes, it was something stupid. I figured it out looking at log. It needed to create subconic/ehcache directory.

Did it need to create that directory in a temp folder, or are you using 0.7.23 or earlier?

I needed to create the folder in /usr/share/tomcat7/subsonic/ehcache. I'm using 0.7.22b.

BTW, just updated to 0.7.24c w/o issue
