Re: [jetty-users] jersey to jsp

Now I'm confused. You say you're using mvn jetty:run BUT you have posted a java main class where you are configuring and running jetty in embedded mode. Which is it? 

Using mvn jetty:run will run jetty inside maven, and deploy the webapp that is your maven project.  It does not run your main class.

Alternatively, you can write a main class to startup up jetty and deploy your webapp. You then need to ensure that all of the required jetty jars and other dependencies are on the execution classpath. You'd need to use something like the maven exec plugin to run it, or run it manually at the command line in the usual java fashion.

I used this archetype.

mvn archetype:generate -DarchetypeArtifactId=jersey-heroku-webapp \

running   as  mvn jetty:run


I made this hack by adding a new class
HelloHandler and commenting out the  line server.setHandler(root)
 , which has worked so far but it is just a hack in the existing Main class. I was hoping I can just an index.html but seems to be too good to be true.  I guess I will have to rework the existing Main class. 

//        server.setHandler(root);
          server.setHandler(new HelloHandler());        

public class HelloHandler extends AbstractHandler
{
    public void handle(String target,Request baseRequest,HttpServletRequest request,HttpServletResponse response)
        throws IOException, ServletException
    {
        response.setContentType("text/html;charset=utf-8");
        response.setStatus(HttpServletResponse.SC_OK);
        baseRequest.setHandled(true);
        response.getWriter().println("<h1>Hello World</h1>");
    }
}


public class Main {

    public static void main(String[] args) throws Exception{
        // The port that we should run on can be set into an environment variable
        // Look for that variable and default to 8080 if it isn't there.
        String webPort = System.getenv("PORT");
        if (webPort == null || webPort.isEmpty()) {
            webPort = "8080";
        }

        final Server server = new Server(Integer.valueOf(webPort));
       
        final WebAppContext root = new WebAppContext();

        root.setContextPath("/");
        // Parent loader priority is a class loader setting that Jetty accepts.
        // By default Jetty will behave like most web containers in that it will
        // allow your application to replace non-server libraries that are part of the
        // container. Setting parent loader priority to true changes this behaviour.
        // Read more here: http://wiki.eclipse.org/Jetty/Reference/Jetty_Classloading
        root.setParentLoaderPriority(true);

        final String webappDirLocation = "src/main/webapp/";
        root.setDescriptor(webappDirLocation + "/WEB-INF/web.xml");
        root.setResourceBase(webappDirLocation);

//        server.setHandler(root);
          server.setHandler(new HelloHandler());        
        server.start();
        server.join();
    }
}

Hi,

How are you running jetty? Are you running in the distribution/embedded/maven plugin? Do you have jsp and it's dependencies enabled?

Making a very simple webapp that is a directory that looks like:

/test
  index.jsp

deploys and runs just fine on the jetty-11 distro, so there must be something else going on with your setup.

Firstly, I would make sure you're using the latest full release version of jetty-11, which is 11.0.1. Then build up from a simple webapp like the one above gradually adding more of your app in until you can see where the problem lies.

Hi,

I am using  working on the heroku  archetype   webapp  for  jersey jax-rs
 section 5.1


It is publishing   jax-rs resources.


The archetype seem to have everything 
to be a webapp also , so I thought I just need to drop jsp in the src/main/webapp/index.jsp

Adding welcome-file-list tag and 
welcome-file  tag with index.jsp.
in the web.xml file.

That didn't do the trick.

I got a 404.
running jetty  11.0.0.beta3.

Can you please tell me what  more is needed for the index.jsp to be published 
.

Regards
