问题 We are using IBM(s) bundled Apache Wink to offer JAXRS endpoints for our application. We are coding towards Websphere 8.5.5. Since we are servlet 3.0 compliant we use the 'programmatic' way of configuring the JaxRS application, meaning no entries in web.xml and we rely on class scanning for annotated jax rs resources. In general it works fine. @ApplicationPath("/api/v1/") public class MyApplication extends Application{ This version of Websphere along with Apache Wink, uses Jackson 1.6.x for

问题 I've some experience developing Java programs. However I have always struggled to understand some basics, such as all the different components that make up a Java Enterprise Application. For example I have implemented RESTful and SOAP based Web services that are consumed from a J2ME application and performed performance and costing tests for my MSC. To develop the RESTful/SOAP based Web services, I used the wizard functionality in Netbeans. It uses JAX-RS to implement the REST web services.

问题 I have a Jersey 1.8 application running. Jersey is running as a Servlet. I need to write a servlet filter that given a plain request/response, is able to figure out which REST resource/method will respond to the request and extract values from annotations. For example, imagine I have the following resource: @Path("/foo") @MyAnnotation("hello") public class FooResource { @GET @Path("/bar") @MyOtherAnnotation("world") public Response bar(){ ... } } When a request GET /foo/bar comes in, I need

问题 I'm developing a Google App Enigne application that uses some REST services and offers in turn web services. I'm using the GAE Eclipse plugin. I have 2 questions: What is the best JAX-RS library to use with GAE nowadays? I'd like to use Jersey because I understand is the most "standard" library (isn't it?), but I could use any in principle... I've been looking for documentation, but I've only found some samples in blogs that only work with old versions of Jersey, etc... For the web services I

问题 Say I have a data class in a JAX-RS 1 environment (RestEasy 2 with the Jackson provider) like this: class Foo { int id; String name; Bar bar; ... } with Bar being: class Bar { int one; String two; } Now I want to have Bar serialized in a special way (perhaps depending on the media type that was requested (or depending the phase of the moon), I would write a MessageBodyWriter<Bar> @Provider @Produces("application/json") public class BarWriter implements MessageBodyWriter<Bar> { ... } which

问题 I am trying to run Jersey 2.1 REST service on JBoss 7.1 AS. I am getting the NoSuchMethodError: javax.ws.rs.core.Application.getProperties error during deployment: ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/RESTService]] (MSC service thread 1-9) StandardWrapper.Throwable: java.lang.NoSuchMethodError: javax.ws.rs.core.Application.getProperties()Ljava/util/Map; at org.glassfish.jersey.server.ApplicationHandler.<init>(ApplicationHandler.java:271) [jersey-server-2

问题 I knew filters are used to handle the request and can do things with http header and httpmethods, but am confused with What is the difference between clientrequestfilter and containerrequestfilter? Inwhich scenario we have to use clientrequestfilter and containerrequestfilter? I tried with this website but not any details about this. Please help me to understand this. 回答1: There are two side to a REST interaction, the client and the server. Jersey/JAX-RS-2 has both a Client API and the "main"

问题 Among all the possibilities to return a response to the client in a REST service, I've seen two possibilities that look equivalent: throwing a WebApplicationException (possibly using a Response instance) or returning a Response instance. Why to use one possibility over the other since the result is the same? Is this related to the REST framework used that may be configured to react differently between exceptions and regular responses? 回答1: Why to use one possibility over the other since the
