JDBC连接硬代码，不使用glassfish连接池

Question

I have a question about the database connection for JPA layer in Glassfish,well, not actually in Glassfish.

I have seen a project using EJB+JPA+Glassfish, however, for the JPA level, the connection to Oracle database is not configured in Glassfish connection pool. It is hard code in JPA level code with JDBC.

I just wondering, will this cause any problems when volumn testing. Will this cause a problem on concurrency.

Answer 1

唯一的“问题”是数据库访问不是由服务器（Glassfish）管理和配置的，而是由硬代码编写的。
