I am trying to connect to a remote MySQL server. I have succesfully made a connection from Eclipse (DataSource view) and can now browse the content of the database.
But now I want to be able to use that database in my Java EE 6 application and it does not work. What I have tried:
Added the username, password, servername, URL, Port as properties in the administration panel.
This is the URL I use: jdbc:mysql://MYHOST:3306/MYDATABASE probably nothing wrong with it. I have also added the my IP to the remote list in CPanel so I am allowed to connect remotely. I have downloaded this driver: http://www.java.net/external?url=http://dev.mysql.com/downloads/connector/j/ and added it to the domains/domain1/lib folder.
I also see 4 other folders there; databases, ext, applibs and classes so I added the driver to in those folders to just to be sure. Is this wrong? Do I need to add the driver to some folder in my Eclipse project in order to get it to work?
Resource Type: javax.sql.DataSource Datasource classname: com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource

If I uncomment what I have commented now the dataTable I use works and the 500 error goes away. But when I try to get it from the database it gives me that.
