WAR application could not be started on Tomcat 8 (Ubuntu 16.04)

[solarchemist]

I am familiar with how to install and update Airsonic WAR on my Tomcat 8 server (running on Ubuntu 16.04).

But when I downloaded the Booksonic WAR file, and deployed it using the Tomcat web GUI "WAR file to deploy" button, the application fails to start, and I get the following log messages. (I also tried installing the WAR via the commandline and got the same results).

In /opt/tomcat/logs/catalina.2019-11-11.log:

11-Nov-2019 17:24:18.607 INFO [localhost-startStop-1] org.apache.catalina.startup.HostConfig.deployWAR Deploying web application archive [/opt/tomcat/webapps/booksonic.war]

And the full details hinted at above were found in /opt/tomcat/logs/localhost.2019-11-11.log:

Other than an Airsonic server, I have no other web applications installed on Tomcat. Have I found a bug, or is the error just due the existing Airsonic application? But as far as I know, it should be possible to run an arbitrary number of WAR applications on the same Tomcat server.

I have attempted to restart the Tomcat server. No effect.

Any luck finding a solution @chepec?

[solarchemist]

@dhawkes I'm not sure there is a solution. My impression of the project was poor to start with, and most issues in the queue appear to be languishing. I made this issue in the hopes of being proved wrong.

I might give it another try if a new release is made or if docs are improved.

[dhawkes]

Hm. That's too bad @chepec. This project had a lot of advantages that I liked, and seemed easy to setup, but I don't think that I have the time or the inclination to start digging into an unfamiliar Java framework haha. Based on the quality of the website and the app support, I thought it would be fine. I think that I'm going to try out Plex Media server, it looks like people have added meta data support for Audiobooks, main downside IMO is that you have to pay if you want to have the audiobooks offline, which I generally need.

Closing without fix, project discontinued. See https://github.com/popeen/Booksonic-Air.
