how are you building/deploying the application?
It looks like (as is stated in the stack trace) that some of the classes that you are trying to deploy have compilation problems.
You need to fix these before the application will run.
1) do you have any code deployed to the jre/lib/ext directory for your java version?
2) do you have any custom jars added to the tomcat/common/lib (or equivalent for your Tomcat version)
3) what version of the JDK are you using to compile your code?
4) what version of the JRE are you using to run Tomcat?
