There are probably too many to list here, but I understand the improvements in CMP beans is great, and the ability to use Message driven beans and all the features of EJB2.0, assuming you are not currently deployed in a J2EE environment under EJB2.0.

Many of the EJB 2.0 features have been available for quite some time under WebLogic 6.x. However, the CMP 2.0 implementation was rather touchy. The main benefit of 7.0 is that it is J2EE 1.3 Certified, so you can be sure the entire spec is implemented appropriately. Though, that is not to say that you won't find the occasional bug here or there. WebLogic 7.0 also has better clustering support. JMS is even starting to take shape as a clusterable service (though not fully in 7.0). The next version of WebLogic (to be released this March) should bring even better support for clustering. Lastly, I have seen better performance and stability from WLS 7.0 over 6.x. However, your mileage may vary... [ February 23, 2003: Message edited by: Chris Mathews ]
