But defining and changing those decisions (business rules) can be a challenge with traditional software solutions.
ILOG BRMS solutions allow your organization to make easy, safe and reliable decision changes. We give you the right tools in the right environments for every stakeholder with a role in managing automated decisions.
With a BRMS, developers and architects can extract the business logic from the traditional code of an application. When business policies are hard-coded into an enterprise application, the process of updating the system requires specialist programming staff, puts the stability of the system at risk, and can take a long time. By externalizing the business logic from a business application with business rules, IT users can develop and run the business logic independently of the application.
ILOG JRules is a Business Rule Management System (BRMS) that allows both business and IT users to manage the rules that drive business.

这个问题在之前bsdts里也遇到过，主要是因为在appfuse生成的项目里配置文件jdbc.properties里都使用了占位符 placeholder，如果项目需要正常在Eclipse的Tomcat里Run里来，这个文件的占位符应该正确的给Replace掉。出现上面的异常 主要就是占位符没有被正确的Replace掉。好了，既然原因找到了，我们下面来看下如何解决。
在Bsdts里面遇到这个问题的时候，我们经常是重新在Console下面运行mvn package 或者mvn install后，再重新Deploy就可以了。但是实践证明在mgsclp里面是行不通的。这是为什么呢？
经过查看mgsclp里的Target里的jdbc.properties文件,发现其已经给正确Replace掉了。只是没有正确地给Eclipse Deploy到tomcat里。
根据上面，我初步确定是Eclipse配置的问题。
我们现在知道的情况有哪些呢?
一是maven是会把placeholder自动replace的.这个我们可以通过查看Target/classes目录下面的jdbc.properties文件可以看到,经过maven处理后的placeholder是给正确replace了.
2.在Eclipse里面部署过后的jdbc.properties文件的plackholder没有被replace掉.

Solution：
我们的jdbc.properties文件就是位于src/main/resources目录下面的.我们可以看到Excluded里面已经有很多 properties给Excluced了.这是i18n的文件,同样也是需要maven进行编码处理的,而jdbc.properties文件是要进行 replace plackholder处理.本质上是一样的.这里把文件加进去后,eclipse也不会进行处理的.所以,我们需要把jdbc.properties文 件同样加入excluded里面.我们不需要Eclipse对这些文件进行处理.maven处理就行了.这样子,Eclipse 就不会把maven处理的结果用原来的版本覆盖了.

好,现在说回到部署问题.我们的War工程在maven里,只要把target/classes里的东西与src/webapp里面的东西放到 Tomcat就行了.这次相关的配置文件有org.eclipse.wst.common.component. Eclipse是如何知道哪些内容需要部置到Tomcat就是在这个文件里面定义的.关键的节点就是<wb-resource>.由前面所说 我们需要的内容只有两个target/classes,src/webapp.所以实际上我们只要把这两个目录上面的东西放到正确的部署位置就行了.其它 内容都是多余的.于是我只保留下面两个内容
<wb-resource deploy-path="/" source-path="src/main/webapp"/>
<wb-resource deploy-path="/WEB-INF/classes" source-path="target/classes"/>
这里的部署,只是把这里指定的目录Copy过去而已不做任务处理,(从我目前观察的情况是这样子的).
我们之前为什么不会呢,就是因为有很多个这样的节点.有些节点会引用没有处理过的文件.Eclipse再一次把没有处理过的文件盖掉处理过的文件,就出现的我们刚开始的时候的问题了.

好了，今天就到这里。

]]>Reading 《Pragmatic Software Testing-Becoming an Effective and Efficient Test Professional》http://www.blogjava.net/Tauruser/archive/2008/09/05/227141.htmlTauruserTauruserFri, 05 Sep 2008 03:01:00 GMThttp://www.blogjava.net/Tauruser/archive/2008/09/05/227141.htmlPragmatic Software Testing-Becoming an Effective and Efficient Test Professional from www.freebookspot.com. I am instrest in the title.
Recently, most development team try to use the agile process in the development. And most of them are test driven. I also have done many effort to the test. But I still can't do the job well. I hope this book will give me a new vision on the software testing. This page will record my reading note. As you know I can't have the book finished in a short time, so this page will keep updating. Thanks for your reading, If you have any questions and suggestions, plz give a comment.

Book Structure

The book was divide into 6 parts, as follow.

 Part I - Goals, Strategies, and Tactics

Part II - Risk-Based Testing

Part III - Static Testing

Part IV - Behavioral Testing

Part V - Structural Testing

Part VI - Appendices

Reading note

Part I
Obvious Quesions will be ask, but in many time there is not obvious answer to them. What is effective software testing? What is efficient software testing? What is software testing, anyway? What is quality?
The answer is important, bacause Your answers to these questions determine what you expect to do as a tester. Other people’s answers to these questions determine what they expect you to do as a tester. Having common expectations up, down, and across the organizational chart and throughout the project team is essential to success. Without such commonality, no matter what you do, someone’s sure to be disappointed. With common expectations, you can all strive for the same goals, and support others in their endeavors.

Effective as “producing a decided, decisive, or desired result; impressive.”
Efficient as “productive of the desired effect; especially to be productive without waste.”

Should look at test effectiveness and efficiency from the project perspective, not the test subproject perspective.

Hessian其实是一种RMI技术，已经被集成在Spring Framework中，这样就很方便了。

Error Listener Start
org.springframework.web.context.ContextLoaderListener
Error Listener Start
....
就这么2行，让人一头雾水。昨天检查了一个下午也没发现问题。今天突然在查看错误日志时发现：
Context initialization failed

org.springframework.beans.factory.BeanDefinitionStoreException: Line 14 in XML document from ServletContext resource [/WEB-INF/springctx-datareport.xml] is invalid; nested exception is org.xml.sax.SAXParseException: Element type "bean" must be followed by either attribute specifications, ">" or "/>".

仔细查看了一下配置文件，原来是同组的组员在写配置文件的时候在class="...."后面多了一个引号！
这个Listener Start的问题太隐蔽，如果没有做错误日志估计一直很难发现了
不过这次有了教训，以后也有方向了
