Can't run my servlet from tomcat server even though the classes are in package
- by Mido
Hi there, i am trying to get my servlet to run, i have been searching for 2 days and trying every possible solution and no luck.
The servet class is in the appropriate folder (i.e under the package name).
I also added the jar files needed in my servlet into lib folder.
the web.xml file maps the url and defines the servlet.
So i did everything in the documentation and wt people said in here and still getting this error :
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception

note The full stack trace of the root cause is available in the Apache Tomcat/7.0.5 logs.
Also here is my servlet code :
package assign1a;
import java.io.IOException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import lib.jsonrpc.RPCService;
public class RPCServlet extends HttpServlet {
/**

private static final long serialVersionUID = -5274024331393844879L;
private static final Logger log = Logger.getLogger(RPCServlet.class.getName());
protected RPCService service = new ServiceImpl();
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {
response.setContentType("text/html");
response.getWriter().write("rpc service " + service.getServiceName() + " is running...");
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {
try {
service.dispatch(request, response);
} catch (Throwable t) {
log.log(Level.WARNING, t.getMessage(), t);
}
}
}
Please help me :)
Thanks.
