How to correctly deploy war file to jetty running in docker-compose?

I am trying to run a java servlet on jetty in docker-compose.
This is my docker-compose.yml:
version: "3.2"
services:
app:
image: jetty:9.4-jre8
ports:
- "8080:8080"
volumes:
- /target/example.war:/var/lib/jetty/webapps/root.war
If I docker exec into the container and change into /var/lib/jetty/webapps/ directory (as specified in the docker-compose) I can see the root.war file is present.
I use the following docker command to do that after starting with docker-compose up -d:
docker exec -it <CONTAINER> /bin/bash/
Then cd into the webapps directory and ls.
However on localhost:8080/ I get a 404 response.
This is the HelloServlet.java I am using:
package org.server;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class HelloServlet extends HttpServlet
{
/**
*
*/
private static final long serialVersionUID = 1L;
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
{
response.setContentType("text/html");
response.setStatus(HttpServletResponse.SC_OK);
response.getWriter().println("<h1>Hello Servlet</h1>");
response.getWriter().println("session=" + request.getSession(true).getId());
}
}
And this is the configuration in src/main/webapp/WEB-INF/web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" metadata-complete="false" version="3.1">
<servlet>
<servlet-name>Hello</servlet-name>
<servlet-class>retro.server.HelloServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Hello</servlet-name>
<url-pattern>/hello/*</url-pattern>
</servlet-mapping>
</web-app>
If I run jetty through the maven plugin I get the Servlet responding. Only run in docker-compose or also docker I get only 404.
This is the error I receive in browser:
404 jetty in docker-compose
Is there any additional configuration to be done?
Is there something obviously wrong with the setup?
What I am ultimately trying to achieve is run a GraphQl servlet on jetty in docker-compose!

Unable to run JaxRs web service using Wildfly web server

Hi I am trying to build a Simple JaxRs web service on JBoss developer studio and Wildfly 11 as application server but i am getting following error while i am trying to deploy my maven project :
Failed to start service
jboss.undertow.deployment.default-server.default-host."/JaxRsTest-0.0.1-SNAPSHOT":
org.jboss.msc.service.StartException in service
jboss.undertow.deployment.default-server.default-host."/JaxRsTest-0.0.1-SNAPSHOT":
java.lang.NoSuchMethodError:
org.apache.tomcat.util.descriptor.DigesterFactory.newDigester(ZZLorg/apache/tomcat/util/digester/RuleSet;Z)Lorg/apache/tomcat/util/digester/Digester;
Also i want to inform you that the project is working fine when i use apache tomcat 9 However it throws above mentioned error when I switch to wildfly 11. I am new to java and Specially web service and just started working for a company which uses Jboss eap server which is quite same as wildfly and unfortunately i am receiving same error there as well while working on a web service assignment.
For more reference below is my pom.xml file :

}
Please let me know where i am going wrong with the wildfly.... and Thanks in advance

Wildfly and EAP are a full JEE servers - there is no need to include Jersey dependencies in your pom.xml. Tomcat required that because it is primarily a servlet/JSP engine. Your service looks good but your pom.xml and web.xml are the result using Tomcat. Additionally, you do not need a web.xml any longer if you don't want and you certainly don't need to use Jersey to map it.
You'll want one more file - the Application class that gets things started. It looks something like:
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
/**
* Used to bootstrap JAX-RS. Otherwise this class is
* not directly used.
*/
#ApplicationPath("/rest")
public class RestApplicationConfig extends Application {
// intentionally empty
}
It can go anywhere in your source tree. Note that it takes over the /rest path which is similar to what you had in your web.xml.
The pom.xml below will create a .war file that you can deploy to Wildfly. This is about as simple as it gets and again, remove your web.xml for now.

Maven Web-app deployment file not found

Hi there I an issue trying to deploy my Maven jsp college project to a bluemix server. Every thing work fines locally on my tomcat server. I use cloud foundry to push to the server which is okay. the index page works fine but I can not access the pages i get for example.
Error 404: java.io.FileNotFoundException: SRVE0190E: File not found: /handler
Which is a Java class using annotation instead of setting routes in web xml like so.
#WebServlet("/handler")

You can see my project here .
https://github.com/yawlhead91/ChocolateBarsSurvey/tree/master/BarSurvey
If any one has some help would be great.
Thanks

I made some changes after cloning your git project:
in index.jsp file
change <form action="/BarSurvey/handler" method="POST">
to <form action="/handler" method="POST">
in Handler.java file
change response.sendRedirect("/BarSurvey/results.jsp");
to `response.sendRedirect("/results.jsp");
in results.jsp file
change Return
to Return
Push your application using the java_buildpack
cf push appname -p target/BarSurvey.war -b java_buildpack

Check your web.xml - you are currently using:
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">
When you should be using:
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"

Anyone has an idea how to solve this?
Thank you

Hmm, obviously classloading problems with no very useful hint from the eclipse (osgi) framework...
I've seen from time to time failing apps when they bring their own versions of libraries which collide with some libs that are already part of the provided platform.
Consider this HCP maven blog: there they reference one artifact and most imporantly they use <scope>provided</scope> to tell maven to NOT include the libs into your app's war file (as some jars are already provided by the platform).
My best bet is that at least org.eclipse.persistence is already provided by the platform (and maybe other libs you want as well).

I faced the same error (my Q&A you can find here) and found a solution in this SAP discussion.
For me the error did no longer occur as soon as I added jersey manually and removed the <servlet-class> tag from the web.xml In the end the configuration within the web.xml wasn't necessary at all for my simple rest service (see this answer).
So It seems that this is a Hana cloud platform specific problem.

Maven - Could not resolve dependencies for project X

I'm trying to make a webservice and pack this into a .war file.
Everything worked fine, untill i made some edits to the pom. After a few CTRL+Z's i can't get it back the way is was..
My current (not working pom) gives the following error:

I have added the following jars to my Build Path:
java-json.jar
javax.ws.rs-api-2.0.1.jar
jersey-bundle-1.8.jar
jersey-server.jar
Can anyone give me a hint to make this work properly again?
EDIT: Removing .jars and closing proxy did the trick.
Unfortunatly, the next error is coming in:
SEVERE: Servlet [jersey-servlet] in web application [/com.gis] threw load() exception java.lang.ClassNotFoundException: com.sun.jersey.spi.container.servlet.ServletContainer
Any hints anyone?

Updated:Add jersey-server dependency
