Amazon web services 我一直在做AWS Elastic Beanstalk和RDS的连接

我一直在努力连接我的Tomcat AWS Elastic Beanstalk和RDS

我已经成功地启动了TOMCAT服务器，并按照说明向其添加了RDS

但我不知道如何将我的tomcat服务器连接到添加的RDS服务器

您将看到连接到数据库（Tomcat平台）。但是我不知道如何以及在哪里放置示例源代码

因此，我只是在guide上用示例JSP代码创建了一个测试项目，构建了该项目，并部署到了我的Tomcat服务器上

但它也无法显示以下信息：

HTTP Status 500 - An exception occurred processing JSP page /main.jsp at line 24
type Exception report

message An exception occurred processing JSP page /main.jsp at line 24

description The server encountered an internal error that prevented it from fulfilling this request.

exception

23:   } catch (ClassNotFoundException e) {
24:     throw new RuntimeException("Cannot find the driver in the classpath!", e);
25:   }

你们能帮我一下吗？我已经花了一整天的时间，但还不能解决它。

添加完整的堆栈跟踪，这可能会对发生的事情有所帮助。@Yogesh\u D嘿，我刚刚添加了更多错误消息。我使用了与AWS指南说明相同的源代码，您缺少的

OracleJDBCJAR

，请参阅

java.lang.ClassNotFoundException:oracle.jdbc.driver.OracleDriver

@RedBoy如何在我的EC-2服务器中安装jdbc驱动程序？我应该下载Oracle DBMS并安装吗？不，我觉得你应该用你的应用程序war安装Oracle jar。如果您使用的是maven，那么可以将其包含到包阶段。
