2 things I see wrong with your scenario. 1. When you refer to a servlet, you don't append ".class" to the end of the servlet name. For instance, you wrote:
http://localhost:80/examples/servlet/abc.class which should be: http://localhost:80/examples/servlet/abc 2. You are going through port 80 which is where a normal webserver would be listening. Tomcat listens on port 8080 by default. Unless you are fronting Tomcat with another web server, such as Apache, and using a web connector (and have the configuration for the web connector correct for each context you are accessing) you will not be able to ask Tomcat to serve up .jsp's or servlets. Try your connection like this: http://localhost:8080/examples/servlet/abc That will go directly to Tomcat rather than pass through a web server with a connector. If this works, then your issue is narrowed down to configuring your web connector properly. If it doesn't work, then we can look at other issues such as installing Tomcat in a path with spaces in the directory names. Note: I'm assuming that a class, which is a servlet, exists in the default package (eg... WEB-INF/classes) and is named abc.class for the above link to work.
