Migrating WebLogic Applications to WebSphere Advanced Edition | This redbook will help you plan the migration of an application developed for BEA WebLogic Server, so that the application will run on WebSphere Application Server, Advanced Edition. We explain the differences between the implementations of WebLogic and WebSphere, provide guidance to developers on how to deploy existing applications from WebLogic to WebSphere, and discuss how to design portable new applications that may be deployed on WebSphere or WebLogic. It is not our intention to provide a feature-by-feature comparison of WebLogic vs WebSphere, or to argue the relative merits of the products, but to produce practical technical advice for developers who have to migrate applications from WebLogic to WebSphere.
In today’s high-end, Java-based, enterprise application server market, the two leading products are WebSphere Application Server, Advanced Edition from International Business Machines Corporation, and BEA WebLogic Server from BEA. Both of these products offer robust support for complex Web-based enterprise applications. Moreover, by adhering to Java standards, they offer a level of portability far beyond that attained by earlier transaction monitor technologies. In addition to exploiting the write-once feature of the Java language, these products closely adhere to the Java 2 Platform, Enterprise Edition (J2EE) specification and associated reference implementation from Sun Microsystems. J2EE promotes an architecture for building and deploying Web-based enterprise applications based, in part, on the following standards: • Java Development Kit (JDK) • JavaServer Pages (JSP) • Java Servlets • Enterprise JavaBeans • Java Database Connectivity (JDBC) • Java Naming and Directory Interface (JNDI) • HyperText Markup Language (HTML) • eXtensible Markup Language (XML)
Portability and adaptability are key properties of enterprise applications. By adhering to the J2EE standard, application developers automatically gain a high degree of portability. Given the J2EE support in BEA WebLogic Server and WebSphere Application Server, Advanced Edition, it should be, at least in theory, a trivial task to take an application written for a WebLogic system, and move it over to run on a WebSphere system. In practice, however, there are various reasons why this migration can be non-trivial. As a practical guide, this book identifies the potential trouble spots in such a migration, and guides the reader through this migration task. One word of caution — although WebLogic supports J2EE, its use is optional. The primary focus of this book is on migrating J2EE-compliant applications to WebSphere. Common noncompliant features of WebLogic are also mentioned. Download freeMigrating WebLogic Applications to WebSphere Advanced Edition.pdf here
