(Bryan Castle) Get an introduction to Web Services for Remote Portlets (WSRP), a specification which defines how to leverage SOAP-based Web services that generate mark-up fragments within a portal application. By defining a set of common interfaces, WSRP allows portals to display remotely-running po

(S.Srivatsa Sivan and R. Venkatavaradan) Service Oriented Architecture (SOA) is an increasingly common buzzword in today’s industry. The benefits of a Web services-oriented framework are well appreciated, but not always well-understood. Enterprises planning to convert their conventional backend appl

(Jack Herrington) A lot of value is locked up in your Java code: all your classes and interfaces, as well as their instance variables and methods. You can use these data to create documentation, to build code generators, or to provide metrics for project reporting.

(Micah Dubinko) XML devotees are, as a general rule, thoughtful, creative, and a bit mischievous. So when the calendar rolls around to April 1, a safe bet is that you’ll find some interesting reading across not only the internet, but also on the XML-Dev mailing list. This year held no exception.

This step-by-step article describes how to perform bulk inserts and updates with different Microsoft .NET data providers by using the OpenXML method in Microsoft Visual Basic .NET. The sample project in this article uses the Microsoft SQL Server .NET Managed Provider (SqlClient). However, you ca

(David Mertz) Even though every abstract description of SAX prominently mentions that it is an event-driven interface, very few SAX applications really use SAX for event-driven programming. Instead, SAX is mostly just a way to save memory while extracting data from an XML document. However, over asy

(Jesse Liberty) As noted in previous columns, .NET 2.0 pushes most of ADO.NET into the frameworks level, and provides you with various DataSource controls to make accessing data easy. With the XML DataSource control, you can bind to an XML document just as easily as you bind to tables in a database.

Much like Data Type Definitions (DTDs), Schemas define the elements that can appear in an XML document and the attributes that can be associated with those elements.

(Andrew Glover) Groovy Builders let you mimic markup languages like XML, HTML, Ant tasks, and even GUIs with frameworks like Swing. They’re especially useful for rapid prototyping and, as Practically Groovy columnist Andrew Glover shows you this month, they’re a handy alternative to data binding fra

(Ronald Bourret) The second major use of native XML databases is data integration. XML is well-suited to data integration because of its flexible data model and machine-neutral text format. In addition, XQuery is a good data integration language because of its ease of use, support for transforma
