Amazon AWS Glassfish Mysqldatasource Class 名称错误或未设置类路径

Question

我使用带有 Glassfish Elastic Beanstalk 的预配置 AWS Linux AMI 来部署我的 java Web 服务。我已经成功设置了我的 RDS，当运行ning glassfish 在本地连接到 AWS RDS 时它工作正常。该问题仅在我运行 AWS EBS 上的 Web 服务时发生。据我所见，mysql 连接器似乎存在，但由于某些原因未被应用程序检测到。不幸的是，Glassfish 文件夹隐藏在 linux EC2 中。谁能告诉我应该采取什么步骤来解决这个异常？

     remote failure: Error occurred during deployment: Exception while deploying the app [current-app] : Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.5.2.v20140319-9ad6abd): org.eclipse.persistence.exceptions.DatabaseException

    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 和运行这个 yum，但它不能解决问题。

sudo yum install mysql-connector-java

谢谢

在网上搜索并测试了一些东西之后。我设法找到了问题，glassfish 文件夹在 Amazon Glassfish AMI 上不可见。因此，您必须使用以下代码在您的网页（项目名称>网页）Netbeans 项目中创建一个 Dockerfile（无文件扩展名）。由于某些原因，我的应用程序不会在 domain1/lib 中拾取罐子，所以我把它放在 glassfish/lib

上
