How to deploy servlet?

Dear all,

I am new to Weblogic. I have downloaded weblogic 9.2 and I followed the documentation link http://edocs.bea.com/workshop/docs92/ws_platform/ideuserguide/TutorialGettingStarted/tutGS_Step1.html

I was able to create and test a jsppage. It wors fine. I want to create and run a sample servlet and I don't know how to do that. In my directory where the sample JSP page is, I right clicked and craeted a new .java file.
Here's what I have in that file:

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;

public class HelloWorldServlet extends HttpServlet {
public void service(HttpServletRequest req,
HttpServletResponse res)
throws IOException
{
// Must set the content type first
res.setContentType("text/html");
// Now obtain a PrintWriter to insert HTML into
PrintWriter out = res.getWriter();

out.println("<html><head><title>" +
"Hello World!</title></head>");
out.println("<body><h1>Hello World Servlet!</h1></body></html>");
}
}

If I follow the same steps like I did for the jsppage and I say Run As -> Run on Server.. I get teh following error:

Error 404--Not Found
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.5 404 Not Found
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.

What am I doing wrong? Without having to compile the .java program and place it in a certain directory etc, I just want to know if I can create a java file like I did and deploy it and test it in the Eclipse IDE?

Can you please help me understand ow this works?

Thanks
Anu

I am not sure how to integrate Eclipse and weblogic. But if you want to manually deploy your web app it can be done.

Here are the steps.

Code your servlet.
map it in your web.xml file.
In your weblogic server, copy your web.xml and Servlet class in the autodeploy folder.

You autodeploy directory will be
{bea}\user_projects\domains\{mydomain}\autodeploy\{webapp}\

you would need to copy the web.xml in the \WEB-INF directory and your servlet class files in \WEB-INF\classes folder with entire package structure.

restart the server and you should be able to invoke your servelt from the browser.
