One possible cause is that you have two or more applicable mappings for that URL call. For example: @Path(“/{myParam}”) And somewhere else: @Path(“/{differentParam}”) Now Jersey have no way of telling what method is actually supposed to be called and gives this error.
You need to enable MultiPart feature on your application. Enabling this feature injects necessary message body readers, writers to your Jersey 2 application. Here is how you register them: On the server-side (http-server): final ResourceConfig resourceConfig = new ResourceConfig(MultiPartResource.class); resourceConfig.register(MultiPartFeature.class); On the server-side (servlet deployment): import org.glassfish.jersey.filter.LoggingFilter; import org.glassfish.jersey.media.multipart.MultiPartFeature; import javax.ws.rs.core.Application; import java.util.HashSet; import java.util.Set; … Read more
There are a number of options for deploying into a Java EE 6 container (more specifically a Servlet 3.0 implementation): The simplest is: <?xml version=”1.0″ encoding=”UTF-8″?> <web-app xmlns=”http://java.sun.com/xml/ns/j2ee” xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance” xsi:schemaLocation=”http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_3_0.xsd” version=”3.0″> <servlet> <servlet-name>javax.ws.rs.core.Application</servlet-name> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>javax.ws.rs.core.Application</servlet-name> <url-pattern>/rest/*</url-pattern> </servlet-mapping> </web-app> Then all the @Path and @Provider classes found in your web application will be … Read more
I managed to do it in Resteasy “the JAX-RS way”, so it should work on every compliant implementation like Jersey (recently successfully tested on JEE7 server Wildfly 8, it just required a few changes to the Jackson part because they changed a few APIs). You must define a ContextResolver (check that Produces contains the correct … Read more
In your client code you are not specifying the content type of the data you are sending – so Jersey is not able to locate the right MessageBodyWritter to serialize the b1 object. Modify the last line of your main method as follows: ClientResponse response = resource.type(MediaType.APPLICATION_XML).put(ClientResponse.class, b1); And add @XmlRootElement annotation to class B … Read more
If you use Jackson (a great JSON lib – kind of the standard for Java I believe), you may use the @View annotation to filter what you want in the resulting object. I understand that you want something dynamic so it’s a bit more complicated. You will find what you are looking for here: http://www.cowtowncoder.com/blog/archives/2011/02/entry_443.html … Read more
400 is the best choice in both cases. If you want to further clarify the error you can either change the Reason Phrase or include a body to explain the error. 412 – Precondition failed is used for conditional requests when using last-modified date and ETags. 403 – Forbidden is used when the server wishes … Read more
Note: Please see above comments for further discussion and tips. This error usual means that you have a both a JAX-RS 1 and JAX-RS 2 jar on the classpath. Jersey 2 uses JAX-RS 2 (javax.ws.rs-api-2.0.1.jar), but if you have the jsr311-api.jar also, which is JAX-RS 1, there is a javax.ws.rs.core.Application in each jar. But the … Read more
You can access a single param via @QueryParam(“name”) or all of the params via the context: @POST public Response postSomething(@QueryParam(“name”) String name, @Context UriInfo uriInfo, String content) { MultivaluedMap<String, String> queryParams = uriInfo.getQueryParameters(); String nameParam = queryParams.getFirst(“name”); } The key is the @Context jax-rs annotation, which can be used to access: UriInfo, Request, HttpHeaders, SecurityContext, … Read more
See Update below: You don’t need a Factory If you are using Jersey 2, one solution would be to use Custom Injection and Lifecycle Management feature (with HK2 – which comes with the Jersey dist). Also required would be a Mocking framework of course. I’m going to use Mockito. First create a Factory with mocked … Read more
