How to do code path analysis for a tomcat web application with CodeCover?

I need to do a code path analysis for a java web application that will run inside tomcat. Currently, I have setup jacoco for test coverage. But I have a requirement to do code coverage and identify critical code by doing a code path analysis. I have done similar work with Codecover. But it is for a normal java application that has a UI and main class. But since there is no main class in the web application I cannot follow the same. How to do this with codecover?
