About Tomcat default application

Hello,
I have installed Tomcat 5.5 on Windows 2000.
It's default application is located at:
C:\Program Files\Apache Software Foundation\Tomcat
5.5\webapps\ROOT\index.jsp

If I put any vaild jsp file like Hello.jsp then I can run it using:
http://localhost:8080/Hello.jsp.

In C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\ROOT
directory there is a folder WEB-INF containing web.xml and another
folder LIB.

I have created a folder classes in WEB-INF and I put their the compiled
servlet class file HelloServlet.class.
Why I can't run this servllet using:
http://localhost:8080/servlet/HelloServlet

Is it compulsory to create a deployment descriptor or it is sufficient
to put it in the created classes directory?
What may be the problem in running servlet? How to run it?

How to get rid off from the port 8080? If I set the port to 80 then can
i run the jsp as:
http://localhost/Hello.jsp

Please help.
-Sameer

That usage requires the "Invoker" servlet - which causes lots of trouble
in the long run. See

http://faq.javaranch.com/view?InvokerServlet for a discussion

The port is configured in server.xml - look for a <Connector tag

More or less, nowadays you declare your servlets in web.xml . For more info,
read http://faq.javaranch.com/view?InvokerServlet .

Also, prepare to create a package for your classes; unqualified classes as
servlets are a problem.

Port 80 is the default. If you use anything else, you must explicitly show it.

Thanks for your(s) post!

Now I am able to run Servlets by uncommenting Servlet Invoker related
tags in web.xml.
But I am facing a strange situation.
I always copy the servlet class files in
C:\Program Files\Apache Software Foundation\Tomcat
5.5\webapps\ROOT\WEB-INF\classes directory
I have successfully executed a servlet using the above setting.
Then I changed the source of it a little, recompiled it and copied it
again in the specified directory.
The IExplorer is not reflecting the changes for the same url. I tried
closing and reopening the IExplorer for some times.

Lastly I closed and restarted Tomcat !!!

Now I am getting the desired new output.

Is it necessary to restart Tomcat if we change the class files?
Please clarify.

Yes you have to reload the app to run the later version. You can use the
Admin program to reload on the fly.

Thanks in Advance...
