tomcat 8 FAILs on starting .war services

Question

Link to issue: https://github.com/jenca-cloud/docker-bimserver/issues/1

Link to Dockerfile: https://hub.docker.com/r/connoralexander/docker-bimserver/

Hi all, I am having a problem where Tomcat 8 is not starting services. Tomcat 8.0.30 is successfully installing with set username and password. It is successfully wget 'ing the latest .war file release of the BIMserver and autodeploying as per config. The BIMserver service is then not starting. Upon going to Tomcat manager, we cannot manually start the service as it throws an error FAIL - Application at context path /BIMserver could not be started

I have tried using previous versions of Tomcat 8 and 7 but get the same errors. Any idea on what the issue starting listeners could be?

Solution

org.bimserver.web.WarServerInitializer java.lang.UnsupportedClassVersionError: org/bimserver/web/WarServerInitializer : Unsupported major.minor version 52.0 (unable to load class org.bimserver.web.WarServerInitializer) at

You need to run your tomcat with Java 8 or recompile the offending classes to produce Java 7 compatible bytecode.

[Marged]

Which java version do you use to run Tomcat ? Unsupported major.minor version 52.0. At least one of the components in your WAR needs Java 8.

This is correct - didn't think to just search for that term! Thank you everyone!

[Admin]

Thank you for your help, though its been fixed using java 7. Problem was within the war file.

[Jan]

yes - that would've been the alternative ;-)
