Metacat

I can't reproduce the bug. In mn-demo-5, I removed/backed up /var/metacat directory. So during the configuration, I was asked to input the backup directory. I created the /var/metacat directory and input /var/metadata/.metadata as the backup directory. However, my configuration still showed the deploy directory is "/var/lib/tomcat7/webapps", there is no extra "metacat". Please see the attachment.

I also looked at code:

public static String discoverDeployDir(HttpServletRequest request) {
        ServletContext servletContext = request.getSession()
                .getServletContext();
        String realPath = servletContext.getRealPath(".");
        String contextPath = request.getContextPath();

        Pattern pattern = Pattern.compile(contextPath + "/\\.$");
        Matcher matcher = pattern.matcher(realPath);

        if (matcher.find()) {
            realPath = matcher.replaceFirst("");
        }
        return realPath;
    }

This method guess the deploy directory base on the request object. It shouldn't have the extra "metacat" if the context value is correctly detected.

The issue turns out to be Tomcat 8 has change the format of current path.
In Tomcat 7, it was /opt/local/share/java/tomcat7/webapps/metacat/.
But in Tomcat 8, it is /opt/local/share/java/tomcat8/webapps/metacat
So the fancy pattern match doesn't work.

Since we just want to remove the context part, I used the old lastIndexOf and substring method in the String class. It worked well.
