One needs to registerJAX-RS 2.0InvocationCallbackas a proxy request context property: If you have a proxy with different methods returning different response types then either register an Object bound InvocationCallback or register a collection of type-specific callbacks: Make sure a proxy is created in a thread safe mode if it is being accessed by multiple threads for every new request thread to have its own callback. the Java API for JSON Processing to build an interactive web application that saves an object's properties in the server. If the plugin is disabled, select the checkbox next to it. Here are steps to create a simple Restful web services (JAXRS) using jersey which will return json. Note that SyncInvoker (and AsyncInvoker) expects Entity to represent the request body. Proxy and http-centric clients are typically created by JAXRSClientFactory or WebClient factory methods but JAXRSClientFactoryBean can also be used for pre-configuring clients before they are created. WebClient has several methods accepting JAX-RS 2.0 InvocationCallback and returning Future. As you can see, even the Download-button at mvn. Proxies hide away the details of how URIs are being composed while HTTP-centric WebClients provide for an explicit URI creation. What happened?
