您应该在glassfish管理控制台上为MySQL数据库配置“JDBC资源”+“JDBC连接池” 您可能需要在以下位置部署MySQL jdbc实现库： glassfish安装路径\domains\domain name\lib 并创建EJB单例以检索连接：
@Singleton
@LocalBean
public class DBConnections {
@Resource(lookup = "resource JNDI name")
private DataSource dataSource;
public Connection getConnection() throws SQLException {
return dataSource.getConnection();
}
}
