Mobile Service Architecture - JSR 172

JSR 172 - Web Services Specification 1.0

The J2ME Web Services Specification allows developers to take advantage of existing Web services concepts and conventions when creating clients for enterprise services. It contains an XML parser - a subset of the Java API for XML Processing (JAXP) - as well as APIs that enable XML-based, Remote Procedure Call (RPC) communication (JAX-RPC subset). The J2ME Web Services specification follows the conventions and APIs of preexisting Web services specifications used in the Java Platform, Standard Edition (Java SE) and Java Platform, Enterprise Edition (EE). With JSR 172, developers may leverage the preexisting Web concepts and content to quickly develop and deploy Web services. For more on Web Services visit java.sun.com/products/wsa.

Introduction to J2ME Web Services - JSR 172, the J2ME Web Services API (WSA), extends the J2ME platform to support web services. The API's two optional packages standardize two areas of functionality that are crucial to clients of web services: remote service invocation and XML parsing. This article introduces these two packages, shows you how to use them, and describes the support for them in the J2ME Wireless Toolkit.

Understanding the Web Services Subset API for Java ME - brings information on the JAX-RPC implementation for Java ME (JSR 172) to the developer community. Get the details on Web Services for Java ME, SOAP, data types and more.

Service-Oriented Architecture and Java ME - Take ubiquitous connectivity, a common transport - HTTP, a data representation standard - XML and Java ME, roll it all together and we have Web Services. Always with us and always on. Read Eric Giguere's introduction, then stay-tuned for more in the SOA series.

Ajax-like Asynchronous SOA Calls with Java ME - Part 2 of Eric Giguere's Web Services series details the mechanics of how to do SOA on the Java ME platform. Jump in and master the Ajax idiom.

SOA Without SOAP: The Java ME Perspective - In Part 3 of his SOA series Eric Giguere explores how to do SOA when the target device does not support Web Services (JSR 172). Dig in to learn what your options are.
