hi!
i have recently started using jetty (version 7.3.0.v20110203).
i'm unable to compile the following servlet which uses jetty continuations.

Please HELP.
thanks,
ravi.

import java.lang.*;
import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*; 
import org.eclipse.jetty.continuation.Continuation;
import org.eclipse.jetty.continuation.ContinuationSupport; 



public class ContinuationServlet extends HttpServlet {

  public void service(HttpServletRequest req, HttpServletResponse res)
                                              throws java.io.IOException {

    String reqId = req.getParameter("id");
    
   Continuation cc = ContinuationSupport.getContinuation(req);

    res.setContentType("text/plain");
    res.getWriter().println("Request: "+reqId+"\tstart:\t"+new Date());
    res.getWriter().flush();

    cc.suspend(2000);
    
    res.getWriter().println("Request: "+reqId+"\tend:\t"+new Date());
  }
}

i'm able to compile HelloWorld.java but not this servlet.
i'm using windows and C:\jetty7 is my jetty installation directory.

for compiling:

javac -cp C:\jetty7\lib\servlet-api-2.5.jar;C:\jetty7\lib\jetty-all-$J ETTY_VERSION.jar ContinuationServlet.java

i'm getting the following error:

package org.eclipse.jetty.continuation does not exist

You need to include the jetty-continuation-{version}.jar file in your
classpath.

First off all thanks for your reply.I'm still unable to compile the servlet which uses jetty continuations.I'm still getting
package org.eclipse.jetty does not exist even after including the continuation file in classpath !.I have used the following code for compiling. Embarrassed

Please check for any error.

javac -cp C:\jetty7\lib\servlet-api-2.5.jar;C:\jetty7\lib\jetty-contin uation-7.3.0.v20110203.jar ContinuationServlet.java

You need to include ALL the required jars in your class path. You
removed one that you probably need and replaced it with one you
definitely need. Check the documentation for Jetty to find out what
jars are needed to compile/run servlets that use the continuation api.
