I am running a JSP/Servlet Web application and out of nowhere we experienced some random problems that don't make any sense. I checked the catalina.out file to check the log files, and I noticed it contained some of the following messages

    SEVERE: Error starting static Resources
            java.lang.IllegalArgumentException: Invalid or unreadable
            WAR file : error in opening zip file

         INFO: validateJarFile(/home/weremo/appservers/
           apache-tomcat-6.0.26/webapps   /WMA/WEB-INF/lib/
           servlet-api.jar) - jar not loaded. See Servlet Spec 
           2.3, section 9.7.2. Offending class: javax/servlet/Servlet.class

I am aware of what this message means, but am in the dark as to what could have caused it, or what effects it could have on the application.
