我知道这个问题在持久性用户中很常见。我在很多论坛*问了那么多的帖子和问题，但我还是没有找到解决方案。

I got the solution.As you can see I've edited domain.xml of glassfish server and set the connection pool properties and JNDI. I went to glassfish admin console and edited the connection pool, I get that the server is not recognizing the changes I did. It was showing the URL property like "jdbc:mysql://:3306/", don't know why it didn't get the properties from domain.xml but finally now it is working.
我得到了解决方案。如您所见，我已经编辑了域。glassfish服务器的xml，并设置连接池属性和JNDI。我去了glassfish管理控制台并编辑了连接池，我发现服务器没有识别我所做的更改。它显示了URL属性，比如“jdbc:mysql:/:3306/”，不知道为什么它没有从域获取属性。但现在它终于开始工作了。

To correct this error, go to glassfish admin console, proceed to JNDI>Additional properties tab.
要纠正这个错误，请转到glassfish管理控制台，转到JNDI>附加属性选项卡。
Under the Name column, confirm if the user,password,URL are correct if not edit the values accordingly.
在Name列下，确认用户、密码、URL是否正确，如果不相应地编辑值。
Edit URL to jdbc:mysql://localhost/{database}
编辑jdbc URL:mysql:/ / localhost / {数据库}
Note that {database} is your database name. Save the changes and test.
注意，{database}是您的数据库名。保存更改和测试。
