Chapter 4. JAX-WS. Building a RESTful Web Service with Spring 3.1 and Java based Configuration, part 2. p805-pautassoA.pdf (application/pdf Object) Java Web services: WS-Security with Metro. As you know from "Introducing Metro," the reference implementations of the JAXB 2.x data-binding and JAX-WS 2.x Web services standards are at the core of the Metro Web services framework. But in and of themselves, JAXB and JAX-WS provide only basic Web services support. JAX-WS doesn't cover the WS-* technologies that upgrade SOAP to work in enterprise environments, so other software components are needed to add support for these technologies. In Metro, the main added component is Web Services Interoperability Technologies (WSIT). WSIT is the current incarnation of what was originally known as Project Tango — Sun's effort to ensure interoperability of WS-* features, including security and reliable messaging, with the Microsoft .NET platform.

WSIT provides Metro with support for WS-SecurityPolicy, WS-Trust, WS-SecureConversation, WS-ReliableMessaging, and more. WSIT basics WSIT gets the policy information from a Web Services Description Language (WSDL) service description. Back to top <? <? Sending Attachments with SOAP. SOAP applications often have to deal with more than just simple messages. The payload for a SOAP message can often include a word processing or PDF document, image, or other binary file. This article explains how to use the Message Transmission Optimization Mechanism (MTOM) to send and receive these messages.

Prerequisites This article uses the WSO2 Web Services Application Server (WSAS.) It is recommended that you download and install WSO2 WSAS 2.0. The article uses the servlet edition installed on Apache Tomcat. Any application server can be used with the servlet version, just follow the installation instructions included with WSO2 WSAS. When XML is not enough: binary data There are endless ways to send data over the network. One of the main criticisms of SOAP is its use of XML. Combining binary data with SOAP Ok, so you need to send binary data between applications. Naive approaches One way you might try is to simply dump the binary into a text node. Listing 1. Listing 2.

Figure 1. Web Services How To at JavaRanch. This page collects code snippets that demonstrate how to accomplish a variety of tasks useful for implementing web services. How can I set HTTP headers like SOAPAction or Basic Authentication in my SOAP request? (link)How can I use HTTP Basic Authentication in my JAX-RPC client? (link)With Axis, how can I access authentication information if I use HTTP Authentication? (link)With Axis, how can I find out which service and operation was invoked? (link)What is the simplest possible Java client for a web service? (link)How do I handle WS-Security UsernameTokens with WSS4J? As any other page in this wiki, the page is editable by anyone, so don't hesitate to add useful stuff.

How can I set HTTP headers like SOAPAction or Basic Authentication in my SOAP request? This works for both JAXWS SAAJ and Axis. If "message" is a SOAPMessage object, it can be done like this: MimeHeaders hd = message.getMimeHeaders(); hd.addHeader("SOAPAction", " if (! If (! If (! Web Services FAQ at JavaRanch. This is the FAQ page for the Web Services and Related Technologies forum. Like all other page in this wiki, the page is editable by anyone, so don't hesitate to add useful stuff. What is a Web Service? In simple terms a Web Service is an application or business logic that is accessible using standard Internet protocols. Can I access a web services from any application? Yes, if your application supports HTTP-based request and response (which, thanks to a plentitude of HTTP client libraries like Apache HttpClient, just about any application should be able to do).

Are there any real web services available for testing? Yes, check What are the current free and commercial implementations available for Web Services? Apache SOAP, Axis 1 and Axis 2. Can I access a web service from within a browser? You can use the JavaScript XmlHttpRequest object (read introductions here and here). JAX-RPC is a specification/API for Java developers to develop SOAP based interoperable web services.
