昨天开始想研究一下SUN的petstore，先下载了petstore-1_3_1_02.zip和petstore-1_3_2.zip安装试用，
安装很顺利，但是程序在运行中会抛出异常，异常信息如下：

－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
java.security.PrivilegedActionException: javax.servlet.ServletException: An erro

ttribute}": Unable to find a value for "attribute" in object of class "com.sun.j

我在google上也没有找到解决上面问题的方法，再加上我也没有太多时间去解决这些异常问题，所以在SUN的网站上下载了
J2EESDK1.4安装程序，该安装程序里面带有petstore1.4的例子，那就再试试1.4还有没有上面遇到的问题呢？

安装好J2EESDK1.4后，在安装目录下的/samples/blueprints/有petstore1.4的例子，和petstore1.3一样，里面有详细的
安装说明文档，按照文档的说明，在执行asant时遇到了下面的问题：

－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－

－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－

从上面的错误信息中可以知道，应该是编译的时候缺少TransitionDelegateFactory这个类，搜索petstore1.4
中的所有文件也没有找到TransitionDelegateFactory.*的文件。在google上搜索TransitionDelegateFactory后
发现，在petstore1.4中应该有TransitionDelegateFactory.java文件，而J2EESDK1.4自带的程序却没有这个文
件，这就是编译出错的原因。

在拷贝如下代码保存为TransitionDelegateFactory.java文件，存放在
petstore1.4/src/components/processmanager/src/com/sun/j2ee/blueprints/processmanager/transitions目录下：

－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
public TransitionDelegateFactory() {
9          super();
10      }
11      
12      public TransitionDelegate getTransitionDelegate(String className) throws TransitionException {
13          TransitionDelegate td = null;
14          try {
15              td = (TransitionDelegate)Class.forName(className).newInstance();
16          } catch  (Exception e) {
17              throw new TransitionException(e);
18          }
19          return td;
20      }
21  }
－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－

重新用asant编译，编译成功。按照安装文档说明，把petstore1.4部署到服务器后运行一切正常，今天开始学习
petstore1.4的代码了。哈哈
