问题
I'm using Netbeans 8.1 beta and Glassfish server 4.1, Mysql.
Every time I create connection between my Webapplication with database it's unable to do it.

I already copy the Jar file to glassfish lib, also I already add reference to web.xml.
I face this error:
description The server encountered an internal error that prevented it from fulfilling this request.
exception
javax.servlet.ServletException: javax.servlet.jsp.JspException: Unable to get connection, DataSource invalid: "java.sql.SQLException: No suitable driver found for jdbc/IFPWAFCAD"
root cause

Looks like u are missing jdbc driver for MySql. Download it from here
http://dev.mysql.com/downloads/connector/j/
unzip and copy mysql-connector-java-5.x.xx-bin.jar it into $glassfish_install_folder\glassfish\lib
User proper driver which match jdk and mysql version u are using to avoid errors.

After many hours of trying to get Netbeans (8.2) to work with Glassfish and in particular JDBC, I ditched Glassfish as I realized it was discontinued. Instead installed Payara which seems to be a fork. Pretty easy in that you just use Glassfish settings in Netbeans, just point to a new direction. To get the Connection Pool and JDBC Resources to show up, go to the admin console of Paraya by right clicking the server in Netbeans and choose "View Domain Admin Control". Go to JDBC Connection Pool and manually add "IpwafcadPool". Remember to add properties for User (root) and Password (root). URL has two properties, one upper and one lower case. I changed both to jdbc:mysql://localhost:3306/MyNewDatabase?zeroDateTimeBehavior=convertToNull.
But then for this above issue. I can just confirm that the connector driver must be updated to the latest. I tried with mysql-connector-java-5.1.40-bin.jar (in lib folder), restarted Paraya and now it works like a charm. Now I can FINALLY continue with the tutorial https://netbeans.org/kb/docs/web/mysql-webapp.html. Yep, I learned a lot by troubleshooting this, so thanks for that.
