Question

我使用预配置的AWS Linux AMI和Glassfish Elastic Beanstalk来部署我的java Web服务。我已设法设置我的RDS，并且在运行本地连接到AWS RDS的glassfish时工作正常。只有在AWS EBS上运行Web服务时才会出现此问题。从我可以看到它似乎是mysql连接器，但由于某些原因没有被应用程序检测到。不幸的是，Glassfish文件夹隐藏在linux EC2中。任何人都可以建议我应该采取什么措施来解决这个异常？

    Internal Exception: java.sql.SQLException: Error in allocating a connection. Cause: Class name is wrong or classpath is not set for : com.mysql.jdbc.jdbc2.optional.MysqlDataSource

Error Code: 0. Please see server.log for more details.
    Command deploy failed.

我有SSH并运行此yum，但它没有解决问题。

sudo yum install mysql-connector-java

在网上挖掘并测试一些东西之后。我设法找到了问题，在Glass Glassfish AMI上看不到glassfish文件夹。因此，您必须使用以下代码在Web页面（项目名称＆gt; Web页面）Netbeans项目中创建Dockerfile（无文件扩展名）。由于某些原因，我的应用程序不会拿起domain1 / lib中的jar，所以我把它放在glassfish / lib上

# Use the AWS Elastic Beanstalk GlassFish image

EXPOSE 8080 3306

# Install MySQL dependencies
