Question

我的软件版本是：

Eclipse Indigo SR 1
JBoss AS 5.0.1
JBoss Tools 3.3.0.v20111020-1412-H45-M4
Seam 2.2.2-Final
Oracle 11g数据库
最新的ojdbc6.jar驱动程序
JDK 1.6.0_16
Windows XP

我在Eclipse中连接到我的数据库，创建了一个新的Seam-2项目，并从现有模式中获得了JBoss-Tools逆向工程。我纠正了一些生成的实体对象存在一些问题。现在应用程序将编译并启动，我得到应用程序的“主页”页面，但是当我尝试转到实际提取任何数据的页面时，我得到下面显示的堆栈跟踪。

我也在下面列出了一些源文件。有什么建议？

Answer 1

不确定是什么问题，但我得出结论，在Eclipse中使用热代码替换运行JBoss 5.0.1不起作用。我安装了5.1.0用于eclipse开发，以及一个外部独立5.0.1实例，用于在最终部署之前测试我的应用程序。这种情况运作良好。
