无法用Netbeans创建到GlassFish数据库的连接

我使用Netbeans 8.1 beta和Glassfish server 4.1, Mysql。

每次我在我的web应用程序与数据库之间创建连接时，它都无法做到这一点。

我已经将Jar文件复制到glassfish库，并且我已经添加了对web.xml的引用。

我面对这个错误:

description服务器遇到内部错误，无法完成此请求。

javax.servlet。ServletException: javax.servlet.jsp.JspException: cannot要获得连接，数据源无效:"java.sql。SQLException异常:不为jdbc/IFPWAFCAD找到合适的驱动程序"

javax.servlet.jsp。JspException:无法连接数据源无效:"java.sql。没有找到合适的驱动程序jdbc/IFPWAFCAD "

看起来你缺少MySql的jdbc驱动程序。从这里下载

http://dev.mysql.com/downloads/connector/j/

解压缩并复制mysql-connector-java-5.x.xx-bin.jar到$glassfish_install_folderglassfishlib

请使用与jdk和mysql版本匹配的驱动程序，以避免错误。

花了好几个小时试图让Netbeans(8.2)与Glassfish一起工作，特别是JDBC，当我意识到它已经停产时，我放弃了Glassfish。相反，安装了Payara，它似乎是一个分支。非常简单，因为你只需要在Netbeans中使用Glassfish设置，就可以指向一个新的方向。为了显示连接池和JDBC资源，右键单击Netbeans中的服务器，进入Paraya的管理控制台，选择"查看域管理控制"。进入"JDBC连接池"，手动添加"IpwafcadPool"。记住要为User (root)和Password (root)添加属性。URL有两个属性，一个大写，一个小写。我将两者更改为jdbc:mysql://localhost:3306/MyNewDatabase?zeroDateTimeBehavior=convertToNull.

但是对于上面这个问题。我只能确认连接器驱动必须更新到最新。我尝试使用mysql-connector-java-5.1.40-bin.jar(在lib文件夹中)，重新启动Paraya，现在它像魅力一样工作。现在我终于可以继续教程https://netbeans.org/kb/docs/web/mysql-webapp.html了。是的，我从故障排除中学到了很多，所以谢谢你。
