Servlet that implements RMI

Question

Hi Everyone,
I m planning to implement RMI with servlet. The architecture is as follows:
--> Http request to the server(tomcat) where the servlet will accept the request. It will get the header request and the post request and on the basis of this post request it will invoke RMI to process specific functionality like fetching image from database.
--> RMI then uses JDBC to interact with the database and get required results.
--> The servlet then returns this image back to the client.
Now, I have seen some examples for servlet and RMI but I havent seen a concrete tutorial explaining this situation.
Is my architecture correct ? Is there anything that I m missing ?
Please guide me.
Thank you.

Hi DrClap,
Thanks for your reply.
Well, I did that ! I pasted RMI Client code to Servlets doGet method but it wont compile and gives me 2 errors.
symbol  : class HelloInterface
location: class HelloWorld
HelloInterface hello = (HelloInterface) Naming.lookup ("//xxx.xxx.xxx/Hello"
^
HelloWorld.java:14: cannot find symbol
symbol  : class HelloInterface
location: class HelloWorld
HelloInterface hello = (HelloInterface) Naming.lookup ("//xxx.xxx.xxx/Hello"
                        ^
2 errorsI have the Stub and Interface in web-inf/classes folder but I dont know whats happening over here. I have checked the interface and everything but it wont work.
And my servlet :
try
HelloInterface hello = (HelloInterface) Naming.lookup ("//xxx.xxx.xxx/Hello");
System.out.println("IP Address: "+hello.showIPAddress());
System.out.println("User Name: "+hello.getUsernames());
}catch(Exception e)
System.out.println("Error from hello world: "+e);
