I go over the internet to figure it out why I receive 404 I tried almost all solutions and didn't help. I have:
Eclipse Photom
Tomcat 9
Java version 1.8
Maven project using Jersey 2.27
When I hit http://localhost:8080/Test/rest/testservice I got 404 "Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists."

PROJECT STRUCTURE AND JAVA CLASS
I Have added in Deployment Assembly -> Maven Dependencies also
I solved it. So if anyone experience problems with 404 even the fact that you did everything right then double check these steps:
Always save (CTR + S) pom.xml and web.xml when you make any kind of
modifications
Replace index.jsp with index.html
Right click the project go to Maven -> Update Project
Right click the project go to Run as -> Run on Server (if I run it
manually it doesn't work, but when I go from run as it is working
correctly)
I have created a tutorial with step by step. If anyone wanted please contact me.

After debugging for a few hours, I am seeking help to set up a REST API using Jersey in Java. I am using a Tomcat 6 server and the following is my file structure of the Mavin project:
On the right, the resource which I want to expose can be seen.
For the web.xml I have a file as follows:
<?xml version="1.0" encoding="UTF-8"?>
<!-- This web.xml file is not required when using Servlet 3.0 container,
see implementation details https://github.com/jax-rs -->
<web-app version="2.5">

and for the pom.xml as follows:

I can build the Maven project and start the server. However if I want to add resources to the Server by right-clicking on the server name and clicking on "Add or Remove..." I get a message that I cannot select any resources. I followed the adivce in this question: There are No resources that can be added or removed from the server but it did not help and I also do not get any error messages which could lead me. Any recommendation what I am doing wrong?
When I want to run the Resource on the server by selecting "Run As" and then "Run on Server" I get the following message: The selection cannot be run on the server.
You can't select this project because Tomcat 6 does not support Servlet 4.0 projects. Servlet 4.0 requires Tomcat 9.x, which itself requires Java 1.8. See the Tomcat documentation.
You can lower the facet version, but it makes far more sense to simply use the newer Tomcat version. Tomcat 6 is far past its end-of-life.
I followed a REST API | Web service tutorial on the web and got stuck midway. When I run the server it setups successfully, shows that its running at http://localhost:8080/ as well but as soon as I try to access different servlets, the page reloads and returns with 404 Error Not found. I tried downloading earlier versions of wildfly with no avail. The paths I tried were /demorest, /webapi, /myresources and they were used in conjunction as well.
What could be the problem?
package com.david.demorest;
import jakarta.ws.rs.GET;
import jakarta.ws.rs.Path;
import jakarta.ws.rs.Produces;
import jakarta.ws.rs.core.MediaType;
#Path("myresource")
public class MyResource {
#GET
#Produces(MediaType.TEXT_PLAIN)
public String getIt() {
return "Got it!";
}
}

It's likely that the tutorial is written to deploy to Tomcat. Wildfly has everything you need for JaxRS built in.
To get started you will need three files. First, you need a class that extends javax.ws.rs.core.Application. It can be in any package you'd like:
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
#ApplicationPath("/rest")
public class RestApplicationConfig extends Application {
// intentionally empty
}
Next, you need your service. The one you show should work though I'd have my Path start with a forward slash like #Path("/myresource"). Lastly, you need a pom.xml that produces a war file. I haven't tested yours but I have one that looks like:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/maven-v4_0_0.xsd">

</plugin>
</plugins>
</build>
</project>
That I just verified works. Once you have all of this you can produce a war file that can be dropped into $WILDFLY_HOME/standalone/deployments and Wildfly will run it. But you need to watch the URL. As defined in my pom.xml this will create a war file named jaxrs-simple-sample-1.0-SNAPSHOT.war and this file name becomes part of the URL. In this example, the URL to your service would be http://localhost:8080/jaxrs-simple-sample-1.0-SNAPSHOT/rest/myresource. The rest part of that comes from the #ApplicationPath defined. But the other part comes from the name of the war. If you don't like that, you can add one more Wildfly specific file:
<?xml version="1.0" encoding="UTF-8"?>
<jboss-web>
<context-root>myapp</context-root>
</jboss-web>
This file, in a standard Maven environment, would be named jboss-web.xml and would be placed in src/main/webapp/WEB-INF. This would change the above URL to http://localhost:8080/myapp/rest/myresource.
I'm working on this simple project and have this problem:
HTTP Status 404 – Not Found
Type Status Report
Message /RestTestThree/myService/Calculator/
Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.
Apache Tomcat/9.0.30
I use this setting: JDK 13, Eclipse 2019-12, Tomcat 9.
I tried different URLs and I hope this one is the correct one:
http://localhost:8080/RestTestThree/myService/Calculator/
I tried both model 3 and 4. Tried different dependencies and versions.
When trying to run this project, at some point the Tomcat even won't start, giving the error
Server Tomcat v9.0 Server at localhost failed to start.

My Problem
I have servlets like this:
#WebServlet(name = "MemberController", urlPatterns = {"/MemberController"})
#MultipartConfig
public class MemberController extends HttpServlet {
The problem now, WildFly somehow does not obey annotations. When I access the URL, this is what I got in my browser (copied by viewing source HTML):
<html>
<head><title>Error</title></head>
<body>Not Found</body>
</html>
I have to declare everything in web.xml (adding to previous file) for what I've declared as annotations.
<servlet>
<servlet-name>Test</servlet-name>
<servlet-class>com.example.training.controller.MemberController</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Test</servlet-name>
<url-pattern>/MemberController</url-pattern>
</servlet-mapping>
When I reupload the exact same WAR file to Tomcat, the annotations are read correctly.
My question is, why? And how to make WildFly recognize those annotations?
Thanks for the file. It's Java 10. I noticed during the build I get:
[INFO] --- maven-war-plugin:2.2:war (default-war) # SampleForError ---
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by com.thoughtworks.xstream.core.util.Fields (file:/home/scott/.m2/repository/com/thoughtworks/xstream/xstream/1.3.1/xstream-1.3.1.jar) to field java.util.Properties.defaults
WARNING: Please consider reporting this to the maintainers of com.thoughtworks.xstream.core.util.Fields
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release
A similar warning is produced when Wildfly starts up. Some combination of Wildfly 12 and Java 10 doesn't work right in JEE7 mode.
However, there are multiple workarounds. If you run Wildfly in EE8 Preview Mode then it works. Do this by running either bin/standalone.sh -Dee8.preview.mode=true or bin/standalone.sh -c standalone-ee8.xml
Otherwise, this works without any changes in Java 8.
As an aside, you're trying very hard to confuse any container you're running in. You specify servlet spec 4 in your pom.xml but then your web.xml is:
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
So your web.xml tells the container that you're using Servlet spec 2.3. If you really need servlet spec 4.0 then your web.xml should be something like:
<?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_4_0.xsd"
version="4.0">
</web-app>
I started create a new java web application scalable, but is not working, since i got error
"503 Service Unavailable No server is available to handle this request".
Im using RESTful service
My code is:
TestClass
#Path("/test")
public class TestClass {
#GET
public String getName() {
return "John";
}
}

In my Haproxy.cfg, i have this line option httpchk GET /myApp
Anyone can help?
If you do not have something in your application listening on the root context (/) then the haproxy will see your application as being down. You either need to have something listen on the root context, or change the monitoring option to point to a url that is returning a 200 (success) when it is polled.
Did you change the httpchk GET / to the httpchk GET /myApp?
Even if you change your application to be deployed at /myApp, you still need something that gives a 200 success on that url.
