JAX-WS Callback Example

1. Introduction Java Architecture for XML Web Services (JAX-WS) is a Java programming language for creating web services, particularly SOAP services. JAX-WS provides both Callback and Polling mechanisms to invoke web services asynchronously. In Callback mode, the client provides a callback handler to accept and process the inbound response object. In this example, I will demonstrate how to invoke a JAX-WS ...

JAX-WS JAXB Example

1. Introduction Java Architecture for XML Web Services (JAX-WS) is a Java programming language for creating web services, particularly SOAP services. Java Architecture for XML Binding (JAXB) is a Java-XML binding technology that simplifies the development of web services by enabling transformations between a schema and Java objects, and also between XML instance documents and Java object instances. Both JAX-WS ...

JAX-WS Dynamic Proxy Client Example

1. Introduction Java API for XML Web Services (JAX-WS) is a Java programming language for creating web services, particularly SOAP services. JAX-WS wsimport generates java stubs and binds the web service during the compile time. The generated client code binds to the WSDL at a specific service implementation. Clients need to regenerate the stubs when WSDL is updated. JAX-WS provides libraries ...

JAX-WS BindingProvider Example

1. Introduction Java API for XML Web Services ( JAX-WS) is a Java programming language for creating web services, particularly SOAP services. BindingProvider is an interface which provides access to the protocol binding and associated context objects for request and response message processing. In this example, I will build a JAX-WS application and demonstrate how to use BindingProvider to set the http header value. ...

Jax-Ws vs Jax-Rpc: Comparison and Differences

In this article, we will compare the JAX-WS and JAX-RPC programming APIs with respect to the Java programming model. Note: This article is for academic purposes only. JAX-RPC is obsolete and its use is discouraged for any new Java development projects. 1. Introduction The Web Services Architecture evolved in part to address interoperability between disparate and heterogeneous systems. SOAP (Simple ...

Jax-Ws LogicalHandler Example

In this example, we will show you how to implement a JAX-WS Logical Handler. 1. Introduction When you send a request to a web service, the SOAP message may require verification. The SOAP message response may also require verification. For these requirements, you can use a SOAP message handler to intercept the SOAP message for further processing. SOAP message handlers ...

Jax-Ws AsyncHandler Example

In this example, we will show you how to implement an asynchronous SOAP web service and client using the AsyncHandler callback handler. 1. Introduction There are two ways to invoke a web service, synchronously and asynchronously. When invoking a web service synchronously, the client must wait for the response before resuming its work. When invoking a web service asynchronously, the ...

Jax-Ws Attachment Example

In this example, we will show you how to exchange files with a SOAP web service using attachments. 1. Introduction You may need to send or receive binary data, such as an image file or a PDF file, in a SOAP message. If the binary data is large, it would be inefficient to send it as part of a typical ...

JAX-WS Web Service Example

In this example we shall learn implementing JAX-WS Web Service. JAX-WS are the API’s provided by Java for implementing Web Service. Here, we shall start by learning what web services are, their architecture, followed by implementation of server and client. We shall also learn the different variants of XML Web Service and the WSDL file which is the contract that ...
