BEA Weblogic Workshop : Kick Start, with CD-Rom

The first book to cover WebLogic Workshop, BEAs new tool that simplifies J2EE development.

• Reviewed and evaluated by BEAs WebLogic Workshop development team.
• WebLogic Workshop lets working developers--not architects--build Web service applications for integration or e-Commerce solutions.
• This books approach provides a rapid introduction for working developers with minimal handholding.

J2EE is a powerful platform for developing applications, but its many features may confuse corporate application developers who only want to build a Web service without learning the complexities of J2EE plumbing. WebLogic Workshop (WLW) is BEAs new tool that will allow developers access to the robustness of J2EE with only a basic foundation in Java coding. And WLW works with BEAs market-leading J2EE application server, WebLogic Server, so that thousands of current WebLogic developers can use it to easily model and design new applications. BEA WebLogic Workshop will explore the features of WLW as it teaches developers to build J2EE applications. It will show how WLW works with SOAP, UDDI, XML, and WSDL to build Web services, and includes a quick tour of Java fundamentals. Throughout the book, the authors offer hundreds of practical example applications developed using WebLogic Workshop.
