Question

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

我在几个网站上找到了一些步骤，但没有什么能帮助解决我的问题。更具体地说，其中一些tutos与其他tutos完全相反。

所以，我的服务器TOMCAT运行正常，我可以获得我的Web应用程序的fisrt页面。问题在于与数据库的连接。我试着自己解决，但我肯定需要一些帮助。

以下是问题：首先，当我启动服务器时，日志控制台会给我这个：

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

但它不取消服务器启动。

但是当页面需要访问数据库（AS400 / DB2）时，它无法正常工作。请参阅以下内容：

[BDD ERROR] Impossible d'ouvrir la connexion, ou connexion inutilisable: Cannot create JDBC driver of class 'com.ibm.as400.access.AS400JDBCConnectionPoolDataSource' for connect URL 'jdbc:as400://OLA'

有人能帮我解决这些问题吗？你需要一些conf / context文件吗？

非常感谢你的帮助。
