Question

I’m getting this error message when trying to deploy my webapp in Tomcat:

FAIL - Application at context path /skynet could not be started
FAIL - Encountered exception org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/skynet]]

Naturally, the first thing I did is to check log/catalina.out (as various other pages on this site say) but there is absolutely no information there (but the log isn’t broken, there’s a lot of output by other apps).

First I thought the problem might be that I apparently compiled to Java 7 but am running it on Java 6, but after fixing the compilation the problem remains.

Environment:

Tomcat 7.0.26

java version "1.6.0_24"
OpenJDK Runtime Environment (IcedTea6 1.11.5) (6b24-1.11.5-0ubuntu1~12.04.1)
OpenJDK Client VM (build 20.0-b12, mixed mode, sharing)

Answer 1

First I thought the problem might be that I apparently compiled to Java 7 but am running it on Java 6, but after fixing the compilation the problem remains.

And this turned out to be the problem after all. I failed when fixing the compilation settings. Now I fixed them for real, and the application starts.

Still, why is this not logged?
