BEA looks to open-source part of WebLogic Workshop
Just saw this article on eWeek. The article states that BEA is slated to announce plans to open-source portions of its WebLogic Workshop tool at the upcoming eWorld conference. BEA has a pretty good record of supporting open-source software and the XMLBeans project is a good example of that. I think the support of AspectWerkz is another example.
If BEA does open-source some of the features of Workshop, this could really help the Eclipse Webtools platform project. I am not a Workshop power user by any stretch of the imagination, but it still does have some pretty cool features. It would be nice to incorporate things like page flow and some of the other cool features into the Eclipse webtools product - Give IntelliJ's Fabrique a run for the money.

Servlet Filters: Part II
Earlier in the month, I blogged about Servlet Filters and how I see them as Aspects in the AOP world. Based on the blog entry, I've gotten tons of email from people that wanted to know more about Servlet Filters, how to use them and how to use the simple Authentication filter I used as an example. I also got quite a few emails from people that wanted to know what other filters I used and so I am including some resources that I find very helpful along with a few servlet filters that I use every day.
