I wanted to implement a file-upload function for my jersey based rest server.
when i set my pom.xml (using maven) to:
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-multipart</artifactId>
<version>2.4.1</version>
</dependency>
<dependency>
<groupId>org.glassfish.jersey.containers</groupId>
<artifactId>jersey-container-jdk-http</artifactId>
<version>2.0</version>
</dependency>
i get following error:
JAX-RS Jersey Error java.lang.NoSuchMethodError: org.glassfish.jersey.internal.util.ReflectionHelper.getContextClassLoaderPA()Ljava/security/PrivilegedAction;
without the "jersey-media-multipart"-dependency the rest server is working but i cant use the file-upload functions.
Following the important part of source code:
ResourceConfig resourceConfig = new ResourceConfig(RestWebServer.class);
//resourceConfig.register(MultiPartFeature.class);
URI endPoint = new URI(pathServer);
server = JdkHttpServerFactory.createHttpServer( endPoint, resourceConfig );
RestWebserver.java:
#Path("/fileupload")
#POST
#Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(
#FormParam("file") InputStream uploadedInputStream,
#FormParam("file") FormDataContentDisposition fileDetail)
{
String uploadedFileLocation = "c://" + fileDetail.getFileName();
// save it
saveToFile(uploadedInputStream, uploadedFileLocation);
String output = "File uploaded via Jersey based RESTFul Webservice to: " + uploadedFileLocation;
return Response.status(200).entity(output).build();
}
Not a Jersey user so I am just guessing, but you probably have a jar mismatch.
Try replacing your second entry with this:
<dependency>
<groupId>org.glassfish.jersey.containers</groupId>
<artifactId>jersey-container-jdk-http</artifactId>
<version>2.4.1</version>
</dependency>
Basing my guess on the chapter 8, have you registered your client/server code?

I faced a problem with camel REST routes when I switched from camel version 3.5.0 to version 3.8.0.
In the version 3.8.0 all routes from the REST service are generated twice! So at start of the camel context the exception is thrown:
Failed to start route route7 because of Multiple consumers for the same endpoint is not allowed: jetty:http://0.0.0.0:6060/start?httpMethodRestrict=GET
In detail:
I have a simple RouteBuilder to generate REST routes:
#Component
public class RestInterface extends RouteBuilder {
#Override
public void configure() throws Exception {
restConfiguration()
.component("jetty")
.host(urlInfo.getHost())
.port(urlInfo.getPort())
.bindingMode(RestBindingMode.json)
.dataFormatProperty("prettyPrint", "true")
.clientRequestValidation(true);
rest("/")
.get("/start").outType(RepositoryPackageInfo.class).to("direct:start")
.get("/stop").outType(RepositoryPackageInfo.class).to("direct:stop");
// ...
}
}
When I start this code with camel 3.8.0 I get following console output:
...

If I run the same code with camel 3.5.0, the application starts without exceptions, and camel has only 38 routes:
etty-9.4.31.v20200723; built: 2020-07-23T17:57:36.812Z; git: 450ba27947e13e66baa8cd1ce7e85a4461cacc1d; jvm 11.0.4+11

Check if configure method on your RestInterface RouteBuilder is getting called more than once. Multiple calls cause duplicate RouteDefinitions to be added to the RouteBuilder instance which can lead to this error.
One way to solve this is to use boolean value in your RouteBuilder to check if configure method has already been called. Then use this value to early out or to throw an exception.
boolean isConfigured = false;
#Override
public void configure() throws Exception {
if(isConfigured){
return;
}
// Configure routes
isConfigured = true;
}
Encountered similar problem with Camel 2.x running in Karaf + OSGi where modifying config file lead to same error.
Basically configuring CamelContext service caused it to restart while the RouteBuilder services it referenced kept their state leading to situation where their configure method got called the second time leading to same error.
I've got a Restlet based application, and I'm trying to use Restlet client resources to test certain parts of it.
Since upgrading from Restlet 2.2.3 to 2.3.4, my ETag verification tests have started failing. Here's how I was adding the header in the old version:
Series<Header> headers = (Series<Header>) currentClientResource.getRequest().getAttributes().get("org.restlet.http.headers");
if (headers == null) {
headers = new Series<Header>(Header.class);
}
headers.add("If-None-Match", "\"" + eTag + "\"");
currentClientResource.getRequestAttributes().put("org.restlet.http.headers", headers);
Then when calling represent() again on the wrapped clientResource I was getting a 304 Not Modified response (which is what I want).
In 2.3.4 this started returning a 200 OK instead, and I noticed a log message about not setting the If-None-Match header directly.
Instead I'm now trying this:
currentClientResource.getRequest().getConditions().getNoneMatch().add(new Tag(eTag));
However this is still giving me a 200 OK. If I do the request manually through a REST client I can get a 304 Not Modified, so the server is still doing the right behavior. What do I need to do in the tests to see what I want to see?
I made a try and it works for me with version 2.3.4 of Restlet.
Here is what I did:

A server resource that sets the etag on the returned representation:
public class ETagServerResource extends ServerResource {
#Get
public Representation test() {
String test = "test";
String md5 = DigestUtils.toMd5(test);
StringRepresentation repr = new StringRepresentation(test);
repr.setTag(new Tag(md5));
return repr;
}
}
The client that makes two calls: a first one without the etag and a second one with the etag that should return a 304 status code.
// First call
ClientResource cr
= new ClientResource("http://localhost:8182/test");
Representation repr = cr.get();
Tag tag = repr.getTag();
System.out.println(">> cr = "+cr); // Status code: 200
// Second call
cr.getRequest().getConditions().getNoneMatch().add(tag);
cr.get();
System.out.println(">> cr = "+cr); // Status code: 304
I don't know what you use within the server resource. Feel free to tell me.
Hope it helps you,

I am starting with REST Assured, getting error while executing below code :
Code 1-
RestAssured.expect().statusCode(200).
body(
"name", equalTo("Russia")
).
when().
get("http://restcountries.eu/rest/v1/callingcode/7");
Exception-
Exception in thread "main" java.lang.Error: Unresolved compilation problem:
The method equalTo(String) is undefined for the type
Code 2 -
RestAssured.expect().statusCode(200).
body(
"name", Matchers.equalTo("Russia")
).
when().
get("http://restcountries.eu/rest/v1/callingcode/7");
Exception-
Exception in thread "main" groovy.lang.MissingMethodException: No signature of method: com.jayway.restassured.internal.ContentParser.parse() is applicable for argument types: (com.jayway.restassured.internal.RestAssuredResponseImpl, com.jayway.restassured.internal.ResponseParserRegistrar, com.jayway.restassured.config.RestAssuredConfig, java.lang.Boolean) values: [com.jayway.restassured.internal.RestAssuredResponseImpl#753455ab, ...] Possible solutions: wait(), any(), grep()
Below are the only 2 methods in my class, I am having issue with first one, second one is running fine. Please let me know what I am missing in first method.
Method -1
public static void testCountriesCallingCode() {
RestAssured.expect().statusCode(200).
body(
"name", equalTo("Russia")
).
when().
get("http://restcountries.eu/rest/v1/callingcode/7");
System.out.println(RestAssured.get("http://restcountries.eu/rest/v1/callingcode/7").asString());
}
Method-2
public static void testCountriesCallingCodeUsingJSONPATH(){
Response res = RestAssured.get("http://restcountries.eu/rest/v1/callingcode/7");
System.out.println(res.getStatusCode());
String json = res.asString();
JsonPath jp = new JsonPath(json);
System.out.println(jp.get("name"));
}
Thanks Hti, your answer worked. Without the other dependencies, Rest Assured kind of works. I have no idea why Rest Assured website does not note this. Following in pom.xml worked
<properties>
<rest-assured.version>3.0.2</rest-assured.version>
<resteasy.version>3.0.17.Final</resteasy.version>
</properties>
...

Change the body of your first example to:
body(
"[0].name", equalTo("Russia")
)
That is because the JSON response from the server is not an object, but an array, and you have to query for the first object ([0]), then the name (.name).
For the Code-1, for equalTo() method you have to import org.hamcrest.Matchers.*;
For the exception in code 2, it is very hard to mention without looking at the RESPONSE but try to follow below link if you have nested generic parameters in your response.
How to validate nested response using REST Assured?
Please let me know if you have any issue or question. Thanks!
Even though this question is old, I just stumpled upon the second problem:
Exception in thread "main" groovy.lang.MissingMethodException: No signature of method: com.jayway.restassured.internal.ContentParser.parse() is applicable for argument types: (com.jayway.restassured.internal.RestAssuredResponseImpl, com.jayway.restassured.internal.ResponseParserRegistrar, com.jayway.restassured.config.RestAssuredConfig, java.lang.Boolean) values: [com.jayway.restassured.internal.RestAssuredResponseImpl#753455ab, ...] Possible solutions: wait(), any(), grep()
This is due to missing dependencies. In my case I needed to add the dependencies for xml-path and groovy-xml, even though I'm just working with JSON data. So the best thing to do is resolving the dependencies transitively.
equalTo comes from Hamcrest which is a JUnit dependency contained within the JUnit jar. You probably just need to import the static method for it from Hamcrest.
import static org.hamcrest.core.IsEqual.*;
Add a static package for equal to:
import static org.hamcrest.Matchers.*;
Using below code sample from tutorial i can successfully make post to a jax-rs service on glassfish-4.
Client client = ClientFactory.newClient();
WebTarget root = client.target("http://localhost:8080/roast-house/api/coffeebeans");
Bean origin = new Bean("arabica", RoastType.DARK, "mexico");
final String mediaType = MediaType.APPLICATION_XML;
final Entity<Bean> entity = Entity.entity(origin, mediaType);
Response response = root.request().post(entity, Response.class);
response.close();
But it forces to bring a dependency that totals about 4.5mb (resteasy 3.0.5 was ~5mb)
<dependency>
<groupId>org.glassfish.jersey.core</groupId>
<artifactId>jersey-client</artifactId>
<version>2.4.1</version>
</dependency>
I have the feeling i'm using only a portion of the client API, is there any more lightweight clients out there, or how would i go about to construct the request using only standard libraries?
couldnt find somewhere else advice.
I am writing a Restlet JSE Client for a Jersey(!) Restful Service. I already wrote a Jersey client for that and it is working, so the jersey service is alright. Now I get problems in writing a restlet client:
My Service root adress is:
http://localhost:8080/com-project-core/rest, so I call:
ClientResource = service = new ClientResource("http://localhost:8080/com-project-core/rest");
My Basic Auth Credentiels are admin and xxx, so I call:
service.setChallengeResponse(ChallengeScheme.HTTP_BASIC, "admin", "xxx");
Now the problems:
ClientResource service = new ClientResource("http://localhost:8080/com-project-core/rest/ping");
calls up my service. After that I try
String myString = service.get(String.class);
System.out.println(myString);
I get a:
08.07.2012 17:41:48 org.restlet.engine.http.connector.HttpClientHelper start
INFO: Starting the default HTTP client
in my output. Not more! The Junit Test says:
Not Acceptable (406) - Not Acceptable
So he can find the resource but cannot produce #Produces("text/plain") ??
So when I remove #Produces("text/plain") on server side it works!!
For the resourcey my server side looks like this:
#Path("/ping")
#RolesAllowed({"admin", "user"})
public class ConnectedResourceBean implements ConnectedResourceIF {
#GET
#Produces("text/plain")
public String getPingMessage() throws NamingException {
return "Hello World";
}
}
For my pom in set this dependencies:
<dependency>
<groupId>org.restlet.jse</groupId>
<artifactId>org.restlet</artifactId>
<version>${restlet.version}</version>
</dependency>
<dependency>
<groupId>org.restlet.jse</groupId>
<artifactId>org.restlet.ext.xstream</artifactId>
<version>${restlet.version}</version>
</dependency>
As I said, its working with my jersey client.
No way: Restlet had problems with
#Produces("text/plain")
on jersey server side. Can someone explain me that fact?
Edit:
Made it work with
<properties>
<restlet.version>2.1-M3</restlet.version>
</properties>
