把Drools 5.4集成到JBoss AS 7.1.1

Drools5引入了业务逻辑集成平台，它提供了支持规则、工作流和事件处理的统一、集成的平台。一切都是重新设计。

Drools 5可以分成4个主要的子项目：Guvnor（BRMS/BPMS）、Expert（规则引擎）、Flow（处理/工作流）、Fusion（cep/temporal reasoning）。

本文主要说明怎样在JBoss AS 7中使用Drools Expert。

Drools 5.4.0下载地址:

1. 解压下载的Drools 5.4.0压缩包: drools-distribution-5.4.0.Final.zip

2. 在JBoss的modules子目录下创建一个名为org/drools/main的目录。

3. 复制Drools的JAR文件到JBoss/modules/org/drools/main目录。

4. 在JBoss/modules/org/drools/main目录创建module.xml文件，内容如下：

确保WAR文件有正确的依赖，在META-INF/MANIFEST.MF中定义，如下：

Dependencies: org.drools

org.drools是模块名。
