Hi, Here are some of the enhancements in Weblogic6.0 : WebLogic Server 6.0 contains the following new features: Enterprise Messaging Platform � BEA WebLogic Server extends the platform to include high-volume messaging based on Java Messaging Service (JMS). Integrated XML Support � Leverage Extensible Markup Language (XML) capabilities for B2B, EAI, and presentation services. Enterprise JavaBeans (EJB) 2.0 with Message Driven Beans and Advanced Container Managed Persistence -- Take a look into the future of Enterprise Java (J2EE) with BEA's EJB 2.0 implementation. Distributed Transaction Management � The new transaction manager, leveraging BEA's expertise with BEA Tuxedo�, gives developers the ability to do complex, distributed transactions from Java-based applications. New Web-based System Management � New management and usability features greatly enhance administrator and developer productivity. These features dramatically improve every aspect of the application lifecycle - from installation, to configuration, development, deployment and management. J2EE Certification - Certification assures enterprises and developers alike that APIs and development features will work in a uniform way. Web and Object Clustering Enhancements � BEA WebLogic Server 6.0 extends the clustering architecture to improve scalability and high availability. Web Server Enhancements � BEA WebLogic Server 6.0 eliminates the requirement for a separate Web server with a powerful and tightly integrated Web/application server architecture. Security Enhancements � BEA WebLogic Server 6.0 offers new security features including denial of service protection and improved administration. Internationalization � BEA WebLogic Server 6.0 can support virtually any language , including double-byte character-set languages like Japanese kanji Database Multipools � You have always been able to setup jdbc connection pools in WLS, but in 6.0 they allow you to setup a meta pool. You would normally setup your architecture so that you have replicated database servers, and then the pool points to both servers (e.g. Oracle replication). Then if the main oracle instance dies, the multipool will failover to the backup instance. Solid transaction support (Two Phase Commit) -- BEA got the transaction gurus from Tuxedo, and built full XA compliant 2PC transactional support into WLS 6.0. No more weblogic.class.path � Again, if you are used to WLS 5.1 and below you will have run into problems when you didn't setup your weblogic.class.path, CLASSPATH, and/or servlet.class.path correctly. The nasty "ClassCastException" can glare at you if you are not careful. Now JDK1.3 is out, it allows WLS to disgard it's hack with multiple classloaders, and we are left with one CLASSPATH. WLS forces you to use 1.3 and above for the server. Central Admin Server -> Managed Server -- WLS 6.0 has changed it's configuration architecture to come closer to BEA Tuxedo. You have an admin server that holds the configuration for all servers in a given "domain". When you start up the managed servers, they point to the admin and get their config, and code sent over to them. This allows you to centralize your configuration, instead of having properties files all over the network. Stateful Session In-memory replication -- WebLogic clustering has been improved in 6.0. You can now cluster stateful session beans using in-memory replication. The server that holds the state will replicate it to a backup server. If the primary goes down you will be routed across to the backup. Then the backup will become the primary and choose another server as its backup.
Hi Subendu , Thanx for the information.It's great !! But, thing is,can we use every thing as it is in weblogic 6.1 as we use to do in weblogic 6.0.I have gone thro' the migration doc provided by BEA.But, I found everything same there ....I mean, same for weblogic 6.0 and 6.1.So, can I assume that we can follow same guideline for migration for WLS6.0 or WLS6.1? The feature you have mentioned is for weblogic6.0...then what new feature is in weblogic 6.1...what's new in it? Expecting once again a prompt reply.Thanx in advance. Reagrds, Avinash
Hi, Just found this info on the net, thought would be useful. Whats New in Version 6.1: Support for SOAP and WSDL; includes J2EE Connector Architecture 1.0, an open solution for application integration; supports EJB 2.0, Servlet 2.3, and JSP 1.2; support for the latest XML parsing, transformation, Web Services, and standard support for JAXP 1.1, SAX V2.0, DOM Level 2, and W3C Schema; optional asynchronous I/O allows for maximum messaging throughput; the WebLogic/Tuxedo Connector delivers bi-directional connectivity with security between WebLogic Server and Tuxedo, and transaction propagation from WebLogic Server to Tuxedo support for Oracle 8.1.7, with support for BLOB and CLOB data types; EJB caching improvements; all documentation, messages and tools are available in Japanese.
