A small, collection of FAQs on Web Services.

The JAXM API conforms to the Simple Object Access Protocol (SOAP) 1.1 specification and the SOAP with Attachments specification. The complete JAXM API is presented in two packages:

The SOAP with Attachments API for Java (SAAJ) 1.2 specification defines the javax.xml.soap package, which contains the API for creating and populating a SOAP

XML based Web Services are a convenient and very powerful way for companies to deploy new business services and to integrate existing business applications.

You know the scenario, you need to somehow get data from your server to your customer's server and this needs to be implemented tomorrow. No problem, let's write a VB Com object that will create a constant link to the customer's server through Port 1452 and anytime our database is updated it will transmit the data across!

jBroker Web is a runtime and compiler for executing and developing Web Service client and server applications. jBroker Web is a 100% pure Java implementation, which supports Web Services standards such as SOAP and WSDL. It brings the familar programming model of Java RMI to the Web Services world.

SOAP is an XML based protocol to let software components and applications communicate using standard Internet HTTP.

SOAP with Attachments API for Java (SAAJ) is used mainly for the SOAP messaging that goes on behind the scenes in JAX-RPC and JAXR implementations. Secondarily, it is an API that developers can use when they choose to write SOAP messaging applications directly rather than using JAX-RPC.

Back in the summer, PHP Cookbook author Adam Trachtenburg covered the basics of web services and SOAP in the OnLAMP.com article A PHP Web Services Client. In the article, Trachtenberg shows how to write a PHP application that accesses Amazon.com's database, as exposed by its web service. He writes: "The options are only limited by your imagination and Amazon's lawyers."

The Apache-SOAP distribution can be installed for use as a client or as a server. This document provides installation instructions for both cases and also has a trouble shooting section to help sort out common installation related problems.

Data provider repositories describe Web services that can be accessed using XML over HTTP, XML over SMTP, SOAP, IIOP and in the future XML Protocol (XMLP).

The World Wide Web Consortium today released SOAP Version 1.2 as a W3C Recommendation. The Recommendation is four documents: the SOAP Version 1.2 Primer, SOAP Version 1.2 Messaging Framework, SOAP Version 1.2 Adjuncts, and the SOAP Version 1.2 Assertions and Test Collection.

A nice collection of SOAP faq.

Please note that this is not a demonstration of SOAP per se: the Topologi Validating Proxy is not a SOAP forwarder and can validate any kind of XML. This demonstration uses SOAP as a typical kind of application: we can imagine the proxy is sitting in front of some SOAP-aware system which the proxy is gatekeeping.

The most basic data integration scenario involves passing data from point A to point B. This is also known as data extraction. The data usually originates from a relational database. The data format is usually a text-delimited file (ASCII or UTF_8). The transfer mechanism is usually FTP. After receiving the delimited text file, it is typically loaded into another relational database.
