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)

Migrating a JBoss EJB Application to WebLogic

The JBoss open source application server is commonly used in the development phase of a J2EE project. In the production phase the commercial BEA WebLogic server is preferred because of its enhanced set of features. Without modifications, an application developed in JBoss does not deploy in WebLogic server. The deployment descriptors for the WebLogic server are different from the JBoss deployment descriptors. An application may be migrated to WebLogic by converting the vendor-specific deployment descriptors to WebLogic. In this tutorial an EJB application developed in JBoss will ... (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.

How to Create a Directory Service Using the OpenLDAP Directory Server

A directory service is an application(s) that stores, retrieves, and modifies information about network resources such as network users. The actual data is stored in a database; a database service is an abstract layer on top of the database. The Lightweight Directory Access Protocol (LDAP) is a lightweight protocol for accessing directory services. LDAP is based on entries; an entry is a set of attributes identified by a globally unique Distinguished Name (DN). Each of a directory entry's attributes has a type and one or more values. The attributes in a directory entry's distingu... (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)
