Hi Bill,

In the logs you sent us, I found this error message:

Caused by: java.lang.UnsupportedClassVersionError: org/labkey/bootstrap/LabkeyServerBootstrapClassLoader : Unsupported major.minor version 51.0
    at java.lang.ClassLoader.defineClass1(Native Method)
    at java.lang.ClassLoader.defineClass(ClassLoader.java:643)
    at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142)

That's a Java 7 class file format, and indicates that you might be running Tomcat with an older Java release. Can you confirm that Tomcat is pointed at a Java 7 installation?

Additionally, catalina.out contained this error:

java.io.FileNotFoundException: /usr/share/tomcat7/logs/labkey.log (No such file or directory)

Can you check if the directory /usr/share/tomcat7/logs exists? Does that look like the right directory for your Tomcat deployment? Perhaps the CATALINA_HOME environment variable is not set correctly?

Also, what version of LabKey Server are you attempting to install? 14.2?

Thanks,
Josh
