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. The JVM options and server classpath have to be set in the startWebLogic script. And to debug ... (more)

JDJ Feature — Java API for XML Web Services (JAX-WS)

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)

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)

XML Schema Binding with XMLBeans

XMLBeans is an open source XML-Java binding tool used to generate Java classes and interfaces from an XML Schema. The generated Java classes may be used to parse or generate an XML document that conforms to the Schema. Some of the advantages of XMLBeans over JAXB are the ability to parse an XML document and support for all of the XML Schema constructs; the JAXB-generated classes do not have a parse method to parse an XML document, and JAXB does not support all of the Schema constructs. XMLBeans provides the XMLObject, XMLCursor, and SchemaType APIs to parse or construct an XML d... (more)

XPath Support in Oracle JDeveloper 11g

XML documents can be used to transfer data. The data in an XML document can be retrieved either with the JAXP (Java API for XML Processing) DOM and SAX APIs, or with the JAXP XPath API. Addressing an XML document with XPath has the advantage of selecting a single node directly without iterating over a node set. In this article, we'll explore XPath support in Oracle JDeveloper-XDK 11g. The article is a book extract from Packt Publishing's Processing XML Documents in Oracle JDeveloper 11g. With SAX and DOM APIs, node lists have to be iterated to access a particular node. Another a... (more)
