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
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 be migrated to WebLogic
with MySQL as the database.

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 WebLo... (more)
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)
Virtualization has been widely accepted as a technique to conserve resources.
Virtualization is the process of running a guest operating system on a
virtual machine, which is created in a virtualizer running on the host
operating system. Large companies do not have to install 100 different host
computers for its employees as they may create 100 different virtual machines
running different guest operating systems on a single host computer.
VMware is one of the main vendors of Linux virtualization solutions. VMware
Player may be used to run 32-bit and 64-bit Linux operating systems ... (more)
Virtualization is the process creating a virtual version of a resource such
as an operating system, network resource or storage device. Virtualization of
an OS involves hosting an OS on another OS using a virtualizer such as Oracle
VirtualBox. Various Linux distributions such as openSUSE, Ubuntu, and Fedora
are available. In this article we'll discuss hosting openSUSE, Ubuntu, and
Fedora on Oracle VirtualBox running on Windows OS.
