Java – access Tomcat context path from Servlet

In my servlet, I want to access the root of the context so that I can do some JavaScript scaling

Minify can be done as part of the installation process, but I want to do this when the servlet starts to reduce the implementation cost

Who knows how to get the context directory so that I can load and write disk files?

Solution

This should give you the real path you can use to extract / edit the file

We did something similar in the context listener

public class MyServlet extends HttpServlet {

    public void init(final ServletConfig config) {
        final String context = config.getServletContext().getRealPath("/");
        ...
    }

    ...
}
