JBoss jBPM 3.1发布: Multiple process languages and simple principles

jBPM is based on a simple principle called 'Graph Oriented Programming.' The basic ideas behind jBPM were coded in less than 120 lines, in the following classes:

• Node.java
• Transition.java
• Execution.java
• Action.java

JBPM还提出面向图形的编程Graph Oriented Programming http://docs.jboss.org/jbpm/v3/userguide/graphorientedprogramming.html

另外 JBpm也开始支持BPEL和Pageflow　

jPDL: a language with clean Java integration and superb task management features.

BPEL: (alpha stage) a service orchestration language based on WSDL and XML.

Pageflow: In JBoss SEAM, we have a simple graph based approach (with Eclipse plugin support) for defining pageflows.

 关于某位大虾发表的为什么他不喜欢Netbeans http://weblogs.java.net/blog/malcolmdavis/archive/2006/02/why_are_you_uni_1.html

主要的原因只是因为他不喜欢Netbeans的字体。

我认为Netbeans有Sun的强力支持，一定会不断完善，而Eclipse过于分散的结构，以及支持的后劲不够，使它 和Netbeans的竞争力逐渐缩小。

Netbeans基于纯Swing的架构，在J2SE 5.0,6.0,7.0，都在不断的优化Swing,而Eclipse对于SWT的支持确仅仅限于开发工具上面。投入远远不够。

基于纯Java的架构将逐渐被基于脚本，配置，工作流，图形等等取代，就拿Ajax来说，Eclipse对它的支持就慢了一拍。

从个人的角度来说，Netbeans对于J2EE开发来说的确是一个梦幻工具，至少非常值得关注。
