By default you can put your servlet, say ExampleServlet.class, into the folder(in your case):
C;\jakarta-tomcat\webapps\examples\WEB-INF\classes\
Then you can call your servlet in browser in this way:
http://localhost:8080/examples/servlet/ExampleServlet Of course you do not have to just put your servlet in above directory, but you have to change the .conf files and .xml files by yourself.
