Setting up JAX RS in an existing non maven web application - java

I'm trying to add jax rs with jersey to my webapplication, which already uses jax ws. It worked with plain text get and put but not with multipart form data.
I'm using
NetBeans 8.2
JDK 8
JAX WS 2.2.6
Metro 2.0
And following libraries for rest/jersey which I took from jersey homepage non maven user zip file:
aopalliance-repackaged-2.5.0-b32.jar

I added a ServiceResource class via the netbeans rest wizard. Which did not work properly i had to add a config class and manually added the service class to the config resources
#javax.ws.rs.ApplicationPath("api")
public class RestConfig extends Application{
#Override
public Set<Class<?>> getClasses() {
Set<Class<?>> resources = new java.util.HashSet<>();
addRestResourceClasses(resources);
return resources;
}
private void addRestResourceClasses(Set<Class<?>> resources) {
resources.add(ws.rest.UploadResource.class);
}
}
So i could use the simple code generated from the wizard and received a text via get after i additionally added the servlet in the web.xml which looks like this:
<servlet>
<servlet-name>rest_let</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>ws.rest.RestConfig</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>rest_let</servlet-name>
<url-pattern>/api/</url-pattern>
</servlet-mapping>
So I was able to access the service. But after adding another method to my resource:
#Path("upload")
public class UploadResource {
#Context
private UriInfo context;
public UploadResource() {
}
#GET
#Produces(MediaType.TEXT_PLAIN)
public String getText() {
return "test";
}
#PUT
#Consumes(MediaType.TEXT_PLAIN)
public void putText(String content) {
}
#POST
#Consumes(MediaType.MULTIPART_FORM_DATA)
#Path("fup")
public Response uploadFile(#FormDataParam("file") InputStream uploadInputStream, #FormDataParam("file") FormDataContentDisposition fileDetail)
{
return Response.status(Response.Status.OK).entity("as expected").build();
}
}
I always get this exception stack:

Is there something wrong in the configuration? I didn't find a good tutorial for setting up rest without Maven so I tried on my own with lots of search on the net, which quite helped but now I'm stuck. It also vexes me because I already tried the same in a Maven project where it worked without a problem.

RESTful API - Getting HTTP 500 error all the time

I am making a simple RESTful API to my application. I've made another package in my project (other from one where is my main java class, servlet, and model). And then I've made my resource file, very simple which looks like this:
package com.java.api;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.core.Response;
#Path("webservice")
public class ZipcodeService {
#GET
#Path("/lookup")
public Response lookup() {
return Response.ok().entity("Los Angeles").build();
}
}
and this is my web.xml:

Perhaps you have problems with your libraries.

java.lang.NoSuchMethodError: org.glassfish.jersey.CommonProperties.getValue(..
by the server initialisation shows that you forgot to add some library (perhaps it's not in your Jersey 2.25, check for it). Your can also try to use another version of Jersey.
You need to look in (and post) your Tomcat logs. Look at catalina.out. It looks to me like your web.xml doesn't have a closing web-app tag, but that might just be because you didn't post the full web.xml.
Also, you need to package your application as a WAR file. Tomcat expects your web application WAR file to be located under the webapps directory.
edit:
the method wasn't found, therefore the appropriate JAR isn't actually on the classpath (lib folder).

Jersey 500 Error NoClassDefFoundError: org/json/JSONException

Before you mark it as DUPLICATE please understand I've checked all the relevant links but to no avail.
I'm calling the following Service.
#Path("/courses")
public class CourseService {
// #GET
// #Produces(MediaType.TEXT_PLAIN)
// public String hello(){
// return "Hello World !!!";
// }
private DataService _service;
public CourseService(String jsonData) throws ParseException, IOException, JSONException {
_service = new DataService(jsonData);
}
#GET
#Produces(MediaType.APPLICATION_XML)
public ArrayList<Course> getAllCourses(){
return _service.get_handler().getAllCourses();
}
}
If I just run the commented portion of the code my application runs fine and produces "Hello World"
But then when I run my actual service it gives me the following error.

You shouldn't be defining dependencies like that. All your dependencies should be managed with something like maven or gradle. That being said, did you add it the jar to the class path?
Since your using maven, you would want to add this to your <dependencies> section. For example:
<dependencies>
<!-- other dependencies -->
<dependency>
<groupId>org.json</groupId>
<artifactId>json</artifactId>
<!-- or w.e. version you wanted to use. -->
<!-- See http://mvnrepository.com/artifact/org.json/json-->
<version>20160212</version>
</dependency>
<!-- other dependencies -->
</dependencies>
Eclipse should automatically add dependencies like the one above to your class path.
Check out one of the official tutorials on maven: https://maven.apache.org/guides/getting-started/maven-in-five-minutes.html

Jersey errors after deploying to tomcat, works fine in Eclipse

I've lost hours trying to pinpoint this annoying issue. I've created a simple Java app that exposes a few REST services using Jersey.
When debugging the application in Eclipse, using a Tomcat 8 server, everything works fine. I then export the project to a WAR file, deploy it to a real Tomcat 8 server, and when I try to call the REST services, I get the below error. I've checked the obvious things: making sure I'm using the correct Java version on the server, making sure the libraries are included, ... But alas, I'm stuck.

I believe this is not because of missing jar.. I believe it is class loading issue. The jersey jars are not being loaded (or) might have been loaded the wrong version. Could you please check the dependencies properly and check for duplicate jars for jersey in your application.
Also Please try by undeploying appliation and deploying again.. This might remove all the classes that were already loaded for taht application and Tomcat might intialize class loading again..
Hope this works...

Unable to send Response from Rest method

Here is the rest ws POST method code:
#POST
#Path("/json/saveuser")
#Consumes("application/json")
public ResponseBuilder saveUserJSON(User user) {
if (save(user)) {
return Response.status(HttpStatus.SC_OK);
}
return Response.status(HttpStatus.SC_BAD_REQUEST);
}
User is saved properly in DB.
But the line Response.status(HttpStatus.SC_OK); and Response.status(HttpStatus.SC_BAD_REQUEST);, is throwing below error:

Not sure what am I missing? Any suggestion?
You have to return a Response instead of a ResponseBuilder:
#POST
#Path("/json/saveuser")
#Consumes("application/json")
public Response saveUserJSON(User user) {
if (save(user)) {
return Response.status(HttpStatus.SC_OK).build();
}
return Response.status(HttpStatus.SC_BAD_REQUEST).build();
}
Your stacktrace obviously points, that Jersey doesn't know, how to response with ResponseBuilder.
Return Response instead: change resource method signature and return result of build method, called upon builder.

I looked into all related posts and also on other blogs/forums but couldnt resolve the issue.
Below is my servlet:
package com.mkyong.rest;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.core.Response;
#Path("/hello")
public class HelloWorldService {
#GET
#Path("/{param}")
public Response getMsg(#PathParam("param") String msg) {
String output = "Jersey say : " + msg;
return Response.status(200).entity(output).build();
}
}
The web.xml file:
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
Restful Web Application
<servlet>
<servlet-name>jersey-serlvet</servlet-name>
<servlet-class>
com.sun.jersey.spi.container.servlet.ServletContainer
</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>com.mkyong.rest</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>jersey-serlvet</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
and the project structure:
I get the error when I try to access the url: http://localhost:8090/RESTfulExample/rest/hello/test
I ve been trying for hours to resolve the problem but without any luck. Does anyone see an error in my project?
Thank you
I had the same issue; in Eclipse try [Project > Clean ...] and restart the server.
Code seems to be fine.. Do not prefer tomcat in eclipse.. Deploy the project to WEB-APPS in tomcat installation folder & try. I am able to see the o/p for this project..
Have fun in solving these kind of issues....
