It sounds to me that what you're trying to do is get a servlet up and
going. If you're hoping to use third party libraries the /WEB-INF/
classes/ folder represents the root directory of your servlet
application... you can place whatever libraries you want to use here
which can be accessed via your servlets. The servlet itself is sort of
like a PHP file, in that it takes care of rendering a web-page on the
fly for a client connecting to it... here's an example of.

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

public class login extends HttpServlet {
   public void doGet(HttpServletRequest request,HttpServletResponse
response)

       throws IOException, ServletException

   {
           String user=request.getParameter("user");// Get info from
forms.

        //Perhaps someone is logged in already...Check Cookies.

        if(user==null||pass==null){

            Cookie[] cookies = request.getCookies();
            Cookie temp;

            if(cookies!=null)
            for(int i=0;i<cookies.length;i++){
                temp=cookies[i];

                if(temp.getName().equals("user"))

                    user=temp.getValue();

                if(temp.getName().equals("pass"))

                    pass=temp.getValue();

            }
        }

        PrintWriter out = response.getWriter();
               response.setContentType("text/html");
        out.println(wrap.runTemplate(""));
        out.close();
   }

   public void doPost(HttpServletRequest request,HttpServletResponse
response)

       throws IOException, ServletException

   {
       doGet(request, response);
   }

}

This is a simple servlet that shows most of the basic functions you'd
probably want to be using, with a bit of code omitted, once you get
something like this up and running, you can put the other libraries
you want to use in the /WEB-INF/classes folder, and access them like
you would in any java application... keeping in mind you use the
response as the output stream.

Ben.

Where did you get these file?  Did they come with
instructions?  Were Javadocs provided for them?
What is the application?

By who?

A quick search on jad file indicates to me that it is more for
packaging applications for mobile phones.  Is that you market?

Yes.

What about them?  Consult that document I linked
and ask further (and smarter) questions if need be.

They are most likely in the .jar, which a quick search
should reveal as being a form of Zip archive, but for Java.
It is possible to rename .jar files as .zip and late model
windows will let you browse into them (but they should
be changed back to .jar extension before deployment).

You need to reference the class that is the (or an)
applet, in the applet element of the web page.
That is where the Javadocs mentioned above, come
in handy.

No. (Unless the target is J2ME on mobile phones)

There are no servlets (directly) involved with applet
deployment.  Applets can be deployed in pure HTML,
on a server that has no servlet ability.

Applet deployment is a specialist area that is very
much not for beginners, even most Java pros would
not be able to deploy an applet reliably to an internet
based audience.  I suggest you hire a consultant.
