将Web项目从Webshpere 7.0迁移到Eclipse Java EE IDE / Tomcat 8.0

Question

我必须将Web项目从Websphere迁移到个人安装：Eclipse Java EE IDE / Tomcat 8.0。

我在几个网站上找到了一些步骤，但是没有任何办法可以解决我的问题。 更明确地说，其中一些芭蕾舞短裙与其他短裙完全相反。

因此，我的服务器TOMCAT运行正常，我可以获取Web应用程序的第一个页面。 问题出在与数据库的连接上。 我尝试自己解决问题，但是我绝对需要一些帮助。

这里是问题：首先，在启动服务器时，日志控制台会向我提供以下信息：

Apr 02, 2015 3:03:47 PM org.apache.catalina.startup.HostConfig deployDescriptor
SEVERE: Error deploying configuration descriptor C:\apache-tomcat-8.0.20\conf\Catalina\localhost\Context.xml
java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: Failed to start component [/Context]

at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source)

但是它不能取消服务器启动。

但是，当页面需要访问数据库（AS400 / DB2）时，它就无法工作。 请看下面：

有人可以帮助我解决那些问题吗？ 您需要一些配置文件/上下文文件吗？

非常感谢你的帮助。
