Seam是一�Ƒ֟�于EJB3.0和JSF的Java EE 5开发框�Ӟ��它通过把JSF与EJB3.0�l��g合�ƈ在一��P��从而�ؓ开发基于Web的企业应用程序提供一个最新的模式。Seam可以让你把EJB�l��g直接�l�定到JSF��面。Seam很大�E�度上依赖于标注(annotations)而不是书写Java代码来构建应用程序。Seam�q�可帮助你把jBPM��程定义直接地集成到你的应用�E�序中�?br />
新的�Ҏ��包括：

workspace management (with automatic breadcrumb generation, if using the Seam conversational model), business process modeling with jBPM integration
reverse generation capability from the Hibernate Tools project

JBoss 宣布发布jBPM 3.1 版本。JBoss jBPM是一个灵�zȝ��、可扩展的工作流��理�pȝ��。它使用��单、强大的语言来描�q�C��务流�E�，把每个流�E�相��x��件打成一个文件包�Q�叫做流�E�档�?par,process archive)�Q�作为JBoss jBPM�q�行服务器的输入�?

JBoss 宣布发布jBPM 3.1 版本�?/strong>

JBoss jBPM是一个灵�zȝ��、可扩展的工作流��理�pȝ��。它使用��单、强大的语言来描�q�C��务流�E�，把每个流�E�相��x��件打成一个文件包�Q�叫做流�E�档�?par,process archive)�Q�作为JBoss jBPM�q�行服务器的输入。JBoss jBPM通过使用JBoss jBPM��程定义语言�Q�jPdl�Q�，在管理�h员与开发�h员之间架��h��通的桥梁。这使得软�g��目�l�理可以更多控制他们软�g开发工作量。在装蝲��程档案(par)之后�Q�用��h��者系�l�可以一步一步地执行�q�个��程。JBoss jBPM负责�l�护��程的状态、日志和执行所有自动的动作。JBoss jBPM��工作流应用开发的便利性和优秀的企业应用集成（EAI�Q�能力结合了��h��。JBoss jBPM包括一个web应用�E�序和调度器。JBoss jBPM可以使用在最��单的环境�Q�比如一个ant ��d��Q�也可以扩展��C��个集��的J2EE应用�?br />
jBPM是基�?面向囑�Ş�~�程"搭徏的。背后最基本的思想�Q�代码只有不�?20行�?br />
jBPM支持以下几种语言�Q?br />
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.

官方提到的更斎ͼ�

Asynchronous continuations (see user's guide, in 'Asynchronous continuations')
Configuration framework (see user's guide, in 'Configuration')
Task instance variables (see user's guide, 'Task Management' section 'Task controllers')
Externalized the hibernate queries: (see user's guide, 'Customizing queries')
Added support for JSF-like expressions in actions and assignments: (see user's guide, 'Expressions').
TaskInstanceFactory replaced the task instance class configuration (see user's guide, 'Task Management' section 'Customizing task instances')
