This tutorial discusses the simpleType and complexType XML Schema structures
and their corresponding representations in an XML document. XML Schema is
used as the basis of an XML document structure, and some of the XML
technologies, such as JAXB, are based on XML Schema.
An XML Schema is an XML-based representation of the structure of an XML
document. XML Schema supports data types and namespaces; a DTD does not. In
this tutorial, the simpleType and complexType structures used to represent a
XML document will be discussed.
SimpleTypes are custom data types used with element and attribute
declarations. A simpleType is represented with a
declaration. An element is used to constrain character data
in a element or a attribute declaration. A simpleType is used to constrain
data types only; a simpleType do... (more)
The Apache Jakarta POI project provides components for the access and
generation of Excel documents. The POI HSSF API is used to generate Excel
Workbooks and to add Excel spreadsheets to a workbook. An Excel spreadsheet
consists of rows and cells. The layout and fonts of a spreadsheet are also
set with the POI HSSF API.
A database table is often required to be presented in an Excel spreadsheet.
Also, a developer's requirement could be to store an Excel spreadsheet in a
database table. The Apache POI HSSF project is an API to create an Excel
spreadsheet. The data in the Excel spr... (more)
The Extensible Stylesheet Language Transformations (XSLT) specification
provides for morphing XML documents into other XML documents. An XML document
can also be transformed into a format other than XML such as HTML or text. An
XSLT processor is required for an XSLT transformation. Some of the commonly
used XSLT processors include Xalan-Java, Oracle XSLT Processor for Java and
the JAXP XSLT transformer. A stylesheet is used to transform an XML document.
The elements of a stylesheet are in the XSLT namespace
With XSLT an XML document may be c... (more)
WebLogic Server 10 Technology Preview supports JEE 5. A feature of JEE 5 is
the Java API for XML Web Services (JAX-WS) used to create Web Services and
Web Service clients. WebLogic Server 10 provides the jwsc task to create the
Web Service artifacts and the clientgen task to create the artifacts for Web
Service clients. In this article we'll create an example JAX-WS 2.0 Web
Service in WebLogic Server 10 Technology Preview.
JAX-WS is an API to create Web applications and Web Services using the
XML-based Web Services functionality. To create a Web Service first create a
Service En... (more)
Cloud computing has been a boon to conserving resources by providing a farm
of servers that are concurrently used by multiple users. Cloud computing
precludes the requirement for setting up per-user servers. In a recent
InformationWeek survey of business technology professionals, most have
indicated a preference for cloud computing for storage, archiving, and
disaster recovery, for business applications, servers, raw computing power,
dedicated data center space, databases, and specialized IT services such as
security, management and compliance.
Cloud computing may be public or ... (more)
