I'm using java 11 and embedded jetty 9 foor my javaEE application,I'm trying to use @Websevlet annotation to publish my servlet but it doesn't work i don't know why. My start class java
import org.eclipse.jetty.annotations.AnnotationConfiguration;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.webapp.*;
public class Start {
public static void main(String[] args) throws Exception {
Server server = new Server(80);
WebAppContext wacHandler = new WebAppContext();
wacHandler.setConfigurations(new Configuration[]
{
new AnnotationConfiguration(),
new WebInfConfiguration(),
new WebXmlConfiguration(),
new MetaInfConfiguration(),
new FragmentConfiguration(),
new JettyWebXmlConfiguration()
});
server.setHandler(wacHandler);
server.start();
server.join();
}
}
My hello world class
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
@WebServlet( "/getservlet")
public class ServletX extends HttpServlet {
private static final long serialVersionUID = 1L;
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<h1>Hi there..</h1>");
}
}
I don't have a web.xml configuration ,Should i do?
If ServletX
is in the war file, meaning it's in WEB-INF/classes/
archive directory, then the configuration you have declared (specifically the AnnotationConfiguration
) will perform a bytecode scan of the WAR file and load the @WebServlet
annotation.
Also note that the WebAppContext
will need point to this WAR file, which your code examples do not do.
WebAppContext wacHandler = new WebAppContext();
waxHandler.setWar("/path/to/myapp.war");
// ... more setup
But! if the ServletX
is not in the WAR file, but is instead housed with your embedded-jetty Start
class, then you'll need to expose the servlet container to be scanned by the bytecode scanning step.
You can always turn on DEBUG/FINE level logging for the named logger org.eclipse.jetty
and see the activity being performed with regards to the deployment and bytecode scanning.
