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?

I'm learning Java web technologies and I'm trying to deploy a trivial REST service using Jersey, when I try to access the resource I get greeted with the following error:
SEVERE: Servlet.service() for servlet [Jersey REST Service] in context with path [/mkstick] threw exception [org.glassfish.jersey.server.ContainerException: java.lang.NoSuchMethodError: 'void jakarta.servlet.http.HttpServletResponse.setStatus(int, java.lang.String)'] with root cause

From what I can grasp it seems to be an issue with versions and I've tried to get every dependency up to date but it has not helped at all.
As comment said, if you are deploying on Tomcat 10.1.x or greater you need to upgrade your jersey version to 3.1+ (it is out now).
To get a starting template use the maven build archetype for Jersey 3.1.1 as seen here.
This is a confusing error too because the updates from Tomcat 10.0.x to Tomcat 10.1.x entail an entire version jump in Servlet spec (version 5 to 6) see link. Usually there arent such big version changes within the same major version ie 10.x
I am new to swagger and jersey.
My api operations are working fine. I followed the steps in the link: https://github.com/swagger-api/swagger-core/wiki/Swagger-Core-Jersey-2.X-Project-Setup-1.5 to add swagger into my api. When I give my try to access the swagge.json via the url:http://localhost:8080/messenger/webapi/swagger.json I get 404 -Not found. Here are my api codes. Can you please help me out with this.

I found the solution to the problem, I changed the swagger-jersey2-jaxrs artifact version to the latest one and also installed the compile dependencies along with it which was provided in the maven repository website.
Please check the version properly!!
I am studying the Spring Framework. I got an error while following a video tutorial. I can't figure out what's wrong. I am using Maven 3.5.0 and runs it in Tomcat 7. I am using GET as the request method.

I am using eclipse as my IDE. It says in the description:
The requested resource is not available.
I have solved it but I do not unrderstand. Does it have to require the base-package="com.in28minutes" in dispatcher servlet to match the packages names?
I always end up with a 404 response.
Resource not found. Testing with tomcat
v8.0. Below are the
details.

Please help !!!!
I just tried restarting the eclipse.
Multiple clean/build/refresh/install.
Checking the Target folder for generated
war and classes. Launching tomcat in debug mode.
But basically didn't change anything in the code.
And yes it works finally.
I am trying to setup a Jersey RESTful service, the problem is that I am getting the following error when trying to do GET request to the following API: http://localhost:8080/GroupAppServer/api/status:

Any ideas why I am getting this error? and how can I fix this?
Jersey servlet in your web.xml is misconfigured.
This servlet parameter should contain valid package name of your JAX-RS resource classes package:
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>GroupAppServer</param-value>
</init-param>
In your case the package name should be com.groupappserver.api and not the value GroupAppServer you've specified.
Also, you can add a new class with extends javax.ws.rs.core.Application and overwrite the method getClasses.
Put your com.groupappserver.api.Status class into the Set returned by getClasses :
package com.groupappserver.api;
#ApplicationPath("/*")
public class ApplicationConfig extends javax.ws.rs.core.Application {
private final Set<Class<?>> classes;
public ApplicationConfig() {
