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. Overview 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.

DTD and XML Schema Structures

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. Overview 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 i... (more)
