I created MySQL pool via Glassfish admin panel. Ping to MySQL from GF admin panel is ok.

I created

Answer 1

This could happen due to a NetBeans bug they say they had fixed but seemingly they had not. As a solution, I ended up removing glassfish-resources.xml altogether (as I couldn't make persistence.xml pick it up with any kind of the workarounds) and using @DataSourceDefinition annotation instead.

My configuration uses a separate DataSourceBean.java file for @DataSourceDefinition:

@Singleton
@Startup
@DataSourceDefinition(name="java:global/jdbc/myDataSource",
    className="com.microsoft.sqlserver.jdbc.SQLServerDataSource",
    url="jdbc:sqlserver://127.0.0.1:1433;databaseName=myDB",
    user="myuser",
    password="mypassword"
)
public class DataSourceBean {
}

persistence.xml looks like that:

    
        java:global/jdbc/myDataSource
