The WebLogic-Eclipse plug-in is designed to run the WebLogic Server from the
Eclipse IDE. With the WebLogic-Eclipse plug-in, the WebLogic Server gets
started and stopped from Eclipse. An application deployed in the WebLogic
Server can be debugged from Eclipse with the plug-in. By installing the
WebLogic plug-in in Eclipse the WebLogic Server can be configured and
administered from the Eclipse IDE by setting the server classpath and JVM
options in Eclipse.
A J2EE developer is commonly required to administer the WebLogic Server and
debug applications deployed in the WebLogic Server. While the WebLogic Server
administration console can start and stop the WebLogic Server, the
administration console doesn't provide for setting the JVM options and the
server classpath. The JVM options and server classpath have to be set in the
startWebLogic script. And to debug ... (more)
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 da... (more)
WebLogic Server 9.x provides database connectivity with data sources. A data
source is a pool of database connections from which a connection can be
obtained. A data source can be configured separately or as a
multi-datasource. A multi-data source is collection of data sources. A data
source is configured with a JNDI binding. A DataSource object is obtained
with a JNDI lookup. A Connection object can be obtained from a DataSource
object with the getConnection() method. WebLogic Server provides an
administration console to configure a data source. WebLogic Server 9.x
includes Ty... (more)
JavaServer Faces (JSF) technology is used for developing server-side user
interfaces (UI) for Java EE applications. JSF 2.0 architecture has introduced
several new features, most of which we shall discuss in this article. The
salient new features in JSF 2.0 are State Saving, Facelets, Navigation,
Validations, Scopes, AJAX, Resource Handling, Composite Components, View
Params, Client Behaviors, Event Handling, and Exception Handling.
In JSF 1.2 the full component tree is saved/restored. Attributes are also
stored and restored. Saving and restoring the full state has pe... (more)
This article compares Document Type Definition (DTD) and XML Schema elements.
Java 2 Enterprise Edition (J2EE) developers use DTDs and schemas in J2EE/XML
applications. When a DTD for an XML document is provided and validation with
an XML Schema is required, the DTD-to-XML Schema conversion creates an XML
Schema document corresponding to the DTD document.
A DTD defines the structure of an XML document and defines a document's
element types, subelement types, and the order and number of each element
type. It also declares the attributes, entities, notations, processing
