Hello, I am also having a problem with my Tomcat's configuration (verstion 5.5.7) but this has to do with running my java servlets which have been put in the appropriate directory but I still get an error 404 message. I reckon it has to do with my java home and classpath settings but I have followed all instructions and still get this error message. Can somebody help me please?

Can you tell if the servlets have compiled, if so the classpath is ok and its your directive to the servlet folder.

If there are no java class files in the folder then you have failed to compile.

Yes they did compile and the class files are present in the folder.

Did you map the servlet classes with the url pattern in web.xml file?

It would be something similar to the following.

<servlet>
  <servlet-name>Hello</servlet-name>
  <servlet-class>exercise.HelloWorldServlet</servlet-class>
 </servlet>

 <servlet-mapping>
  <servlet-name>Hello</servlet-name>
  <url-pattern>/Hello</url-pattern>
 </servlet-mapping>

In case you are calling servlets from other web pages, make sure you have used correct url pattern.
