Question

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

我已经成功启动了TOMCAT服务器，并按照说明向其中添加了RDS。

但是我不知道如何将我的tomcat服务器连接到添加的RDS服务器。

Connecting to a Database (Tomcat Platforms)

您将看到“连接到数据库（Tomcat平台）”。但是我不知道示例源代码的放置方式和位置。

因此，我只是在指导中使用示例JSP代码制作了一个Test项目，构建了该项目，并部署到了我的Tomcat服务器。

但显示以下消息也不起作用：

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

org.apache.jasper.JasperException: An exception occurred processing JSP page /main.jsp at line 24

21:     Class.forName("oracle.jdbc.driver.OracleDriver");
22:     System.out.println("Driver loaded!");
23:   } catch (ClassNotFoundException e) {
24:     throw new RuntimeException("Cannot find the driver in the classpath!", e);
25:   }
26: 
27:   Connection conn = null;

你们能帮我吗？我已经花了一整天了，但还无法解决。

我一直坚持将AWS Elastic Beanstalk和RDS连接起来
