>From where is the ServletContext.class loaded? Is it from
<TOMCAT_HOME>/lib/servlet-api.jar or from another jar-library on the
classpath? My guess is that you have multiple jars containing the
ServletContext.class and not all of these are related to the same
servlet-api version and thus not supporting the getClassLoader() method.
You might be loading the wrong SevletContext class file.
