Passing different values to the same servlet

Question

Hi,
Is there a way to pass different values to the same servlet?
Background:
I have a database that I query to acquire a list of customers, then I show each customer as a link, that when clicked will show details of that customer. (The customer table is dynamic so I can't create a new page for each customer)
When using JSP what I do is
//Do query database
while (rst.next())
     String cust = rst.getString ("cust");
        out.write("<a href = \"cust2.jsp?cust=" + cust + " \" >" + cust + "</a> ");
}Then on the cust2.jsp. I will use
String str = request.getParameter ("cust");to acquire the customer to get details of.
Is there a way to do the same using servlets?
I could swap to JSP when creating this particular part of the project but it won't look good and it would help me learn a few things when there is another way.

I want to know if there is a way to pass a variable from a webpage link like in my JSP example using servlets.
Here is what I wanted to do:
I have a webpage that contains customer names and each name has a link to the same servlet (let's say the link is famia/servb). I want servb to show detailed information about the customer my visitor clicked in the webpage.
The logic I was thinking is to pass a variable to this servlet, then I can use that variable to know which customer should I query in my database. So that I can show the details to my users.
Here lies my problem, I don't know how I can pass this variable, or even know which customer my visitor clicked. I can't use a new servlet for each client since the customer is in a database and if my customer base grows then I would need to create a lot more web page that does the same thing.
The JSP example I gave is how I will be coding it if I am using JSP, but now I am using servlets. So I was wodnering if there is a way to do this using servlet. Or should I stay with using JSP for this particular logic and just call servb after the JSP page acquired the variable.
I'm trying not to use "<original URL> + ? + <variable> = <value>" (eg: http://www.famia.net/customer?cust=famia) as the means for passing the variable. (or in the example as a means of passing variable cust with value famia)
