Packaging Servlets

Move the files to a subdirectory that 

matches the intended package name

We'll use the 

cwp

package. So, the class files need to go 

in a subdirectory called 

cwp

.

Insert a package statement in the class file

E.g., top of SimplerHelloWWW.java:

package cwp;

Set CLASSPATH to include top level 

development directory

Same as with any Java programming, but everyone 

forgets this step!

Include package name in URL

http://localhost/servlet/

cwp

.SimplerHelloWWW

HelloWWW with ServletUtilities 

and Packages

package cwp;

import java.io.*;

import javax.servlet.*;

import javax.servlet.http.*;

public class SimplerHelloWWW extends HttpServlet {

public void doGet(HttpServletRequest request,

HttpServletResponse response)

throws ServletException, IOException {

response.setContentType("text/html");

PrintWriter out = response.getWriter();

out.println(

ServletUtilities.headWithTitle("Hello WWW")

+

"\n" +

"
Hello WWW
\n" +

"");

}

}
