我是应用程序服务器环境的新手。我已经安装了 Websphere Application Server v8.5 和 DB2 v10.1 作为数据库服务器。我需要在 websphere 上托管一个应用程序，它使用 JDBC 数据源连接来连接 DB2 数据库。
现在，该应用程序已成功部署并已在 websphere 管理控制台上启动。当我尝试使用 //hostname:portname/application 运行应用程序时，我收到以下错误：
An unexpected error has occured.
Please consult your system logs for more detailed information.
在“C:\Program Files (x86)\ibm\WebSphere\AppServer\profiles\AppSrv01\logs\server1”进入system.out日志后，发现如下错误：

还需要补充一点，其他应用程序在这个环境中运行良好。我只在其中一个应用程序中面临这个问题。我正在研究 Amazon AWS EC2 M1 中型实例...具有 3.75 GB 内存和 64 位 Windows Server 2012 平台...使用 JDK 6 更新 45。
我知道这可能很幼稚，但我对 Java 环境一无所知，因为我来自数据库/数据仓库领域。请指导我如何找到实际原因并解决此问题。如果专家建议我一些好的在线博客来了解更多关于 Java 应用程序和 websphere 基础知识，我也将不胜感激。
任何帮助都非常感谢。非常感谢。
