Jersey REST 404 error

Question

DISCLAIMER: I have searched whole StackOverflow network, saw a lot of questions with different solutions, but none help as most of them had typos, or wrong .war file name etc. Please, don't mark the question as duplicate.

For the latest project I am working on, I need to use Jersey REST services, but I am totally stuck in 404 error.

Here is the web.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
  <display-name>VideoConverter</display-name>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>

  <servlet>
    <servlet-name>VideoConverter REST Service</servlet-name>
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>videoconverter.rest</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>VideoConverter REST Service</servlet-name>
    <url-pattern>/rest/*</url-pattern>
  </servlet-mapping>
</web-app>

Then, here is the implementation of the REST method I need to invoke:

@Path("/convert")
public class ConvertControllerREST {
    @GET
    @Path("/getcommands")
    @Produces("application/json")
    public List<JSONObject> getCommands() {
        // other logic here
    }

I am calling this REST method on the following URL: http://10.0.2.15:8080/VideoConverter/rest/convert/getcommands

Tomcat 7 logs show no error at all, only 404 - not found when requesting the URL. Downloaded the latest Jersey version available from here: https://jersey.java.net/download.html (RI bundle), and inserted all the .jar files I have found in the bundle above into WEB-INF/lib folder. Also, the .war file I am creating has the same name as stated in the web.xml file: VideoConverter.war.

Any ideas what can be the problem here?

Update 1:

All the jar I am using in the project:

Here are the logs:

Final update: @Meiko answer solves half of the problem. Because new errors appeared, I decided to take his advise and convert the project into Maven archtype to easily solve these problems.

Edit the init-param for package scanning in your web.xml:

<init-param>
    <param-name>com.sun.jersey.config.property.packages</param-name>
    <param-value>videoconverter.rest</param-value>
</init-param>

Or (XOR !) update jersey to 2.x and change the servlet-class:

<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>

com.sun.jersey is the package name for jersey 1.x.

org.glassfish.jersey is the base package of jersey 2.x.

Update

The problem:

SEVERE: MessageBodyWriter not found for media type=application/json, type=class java.util.ArrayList, genericType=java.util.List

You have to add a library which is able to serialize/deserialize JSON (handling the specified media type). See: https://jersey.java.net/documentation/latest/media.html#json

How you can do this is described here too: SEVERE: MessageBodyWriter not found for media type=application/json, type=class com.jersey.jaxb.Todo, genericType=class com.jersey.jaxb.Todo

Just download the bundle here: http://central.maven.org/maven2/org/glassfish/jersey/media/jersey-media-json-jackson/2.22.2/jersey-media-json-jackson-2.22.2.jar

and: http://central.maven.org/maven2/com/fasterxml/jackson/jaxrs/jackson-jaxrs-json-provider/2.7.3/jackson-jaxrs-json-provider-2.7.3.jar

Put the jars in your classpath...

And edit the tag servlet-class to <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>, like already shown. This should be enough.

Advice: I really recommend you to use maven. With a maven archetype you can setup your project very easily:

mvn archetype:generate \
    -DarchetypeArtifactId=jersey-quickstart-webapp \
    -DarchetypeGroupId=org.glassfish.jersey.archetypes \
    -DinteractiveMode=false \
    -DgroupId=com.example \
    -DartifactId=simple-service-webapp \
    -Dpackage=com.example \
    -DarchetypeVersion=2.22.2

To start this application:

mvn clean package tomcat7:run-war

I am running the latest version of Jersey REST, 2.22.2. I have tried changing the servlet class to `org.glassfish.jersey.servlet.ServletContainer` but it didn't worked. Returns 500 error. – Apr 11 '16 at 22:35

Ok, I assume that you have both dependencies in your classpath and maybe you use the old classes in some parts of your project. There should nothing exist in your project with the String `com.sun.jersey` – Meiko Rachimow Apr 11 '16 at 23:36
@DejanStamenov Meikos answer is correct. You might want to share some additional informations like `libs` or `pom.xml`, `startup logs` and your `ResourceConfig` – zyexal Apr 12 '16 at 01:21
@Meiko I don't have any of the old classes that include the `com.sun.jersey`. On this project, the only configuration for the Jersey REST was done by me, some days ago. There was no older version of Jersey before. In addition to this, i don't have `pom.xml` file, as the project is not Maven. I will update my question to include the `lib` folder and all the `jar` files I am using. There is no other configuration in the project right now, that I am not sharing. I have shared all the configurations so far. – Apr 12 '16 at 09:38
You did not share your run configuration. Which classpath is used? Could it be, that an old library is installed in the classpath? The reason why I think, that you have an old version of jersey in the classPath is, that you were able to start the application with: `com.sun.jersey.spi.container.servlet.ServletContainer` But maybe there is another problem before... In fact nobody can help you without the logs your server created on startup and when the 500 error occurs. – Meiko Rachimow Apr 12 '16 at 09:45
@Meiko I have updated my question with logs showing the 404 error. No more info is provided when it shows the 500 error. I can't see any detailed info about the errors and why they occur. About the run configuration, the project has no run configuration set up. I can send you a screen shot if needed. Sorry about the late response, had some work meanwhile that couldn't be delayed. – Apr 12 '16 at 13:17
`org.glassfish.jersey.servlet.ServletContainer` this is the correct `servlet-class` for jersey 2.x – Meiko Rachimow Apr 12 '16 at 13:30
no logs if the 500 error occurs? ... please show all what you have with the correct `` – Meiko Rachimow Apr 12 '16 at 13:32
@Meiko Meanwhile waiting for your response, was adding more logs including error 500. Check it. – Apr 12 '16 at 13:37

`SEVERE: MessageBodyWriter not found for media type=application/json, type=class java.util.ArrayList, genericType=java.util.List.` that is your problem, I think this link would help: http://stackoverflow.com/questions/29136404/severe-messagebodywriter-not-found-for-media-type-application-json-type-class – Meiko Rachimow Apr 12 '16 at 13:39
@Meiko Downloaded the `jar`, but can you please update your question above and let me know how my final `web.xml` should look like with these new changes? I am not sure where to place the `` and ``. – Apr 12 '16 at 13:48
@Meiko Check the latest update after adding the new `jar`. It came up with new errors. – Apr 12 '16 at 14:14
without maven is it hard to get all dependencies, here the next one: http://central.maven.org/maven2/com/fasterxml/jackson/jaxrs/jackson-jaxrs-json-provider/2.7.3/jackson-jaxrs-json-provider-2.7.3.jar (my answer is updated) – Meiko Rachimow Apr 12 '16 at 14:15
@Meiko I did understood that it is hard without Maven, but can't change this project right now. Added the new `jar`, still get the same error. – Apr 12 '16 at 14:20
One point we got... now the `jersey-media-json-jackson-2.22.2.jar` is loaded and the `JacksonFeature` is looking for an `JsonProvider`.... But you still get this in your logs: `java.lang.NoClassDefFoundError: com/fasterxml/jackson/jaxrs/json/JacksonJaxbJsonProvider`? This class is located in the jar http://central.maven.org/maven2/com/fasterxml/jackson/jaxrs/jackson-jaxrs-json-provider/2.7.3/jackson-jaxrs-json-provider-2.7.3.jar (if you want to check it, extract it with unzip) Maybe the jar is not in your class path? – Meiko Rachimow Apr 12 '16 at 16:01
@Meiko Just wanted to notify you that I have taken your advise to convert my project into Maven archtype, and go from there. However, I still had troubles using the Jersey v2.22.2 even in the Maven project (again 404 error's). Because of that reason, I am going to use v1.19, which I had no troubles at all setting it in Maven. Thank you for the great help. Should I mark your answer? Although it solves half the problem, maybe it will help someone else? – Apr 13 '16 at 10:07
try this mvn archetype to setup a jersey 2.x project, it wotked for me: `mvn archetype:generate -DarchetypeArtifactId=jersey-quickstart-webapp \ -DarchetypeGroupId=org.glassfish.jersey.archetypes -DinteractiveMode=false \ -DgroupId=com.example -DartifactId=simple-service-webapp -Dpackage=com.example \ -DarchetypeVersion=2.22.` (https://jersey.java.net/documentation/latest/getting-started.html#new-webapp) – Meiko Rachimow Apr 13 '16 at 10:26
hint: to start this project use: `mvn clean package tomcat7:run-war` – Meiko Rachimow Apr 13 '16 at 10:28
and no problem ;) but I would try to use the new version... good luck for your project – Meiko Rachimow Apr 13 '16 at 10:29
@Meiko Thank you again for the advises, but I will keep the 1.19 version. Don't want to experiment a lot at the moment, cause the time is not working for me. :) – Apr 13 '16 at 11:57
