Re: [jetty-users] jersey to jsp
Hi
Note Jetty 11 is targeting jakarta namespace.
I'm not sure  jersey archetype has been migrated to the jakarta namespace and might be still on javax.
So I would recommend you try with Jetty 10.0.1 or 9.4.38.v20210224

I used this archetype.

mvn archetype:generate -DarchetypeArtifactId=jersey-heroku-webapp \
                -DarchetypeGroupId=org.glassfish.jersey.archetypes -DinteractiveMode=false \
                -DgroupId=com.example -DartifactId=simple-heroku-webapp -Dpackage=com.example \
                -DarchetypeVersion=3.0.1



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.

regards
Jan

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
