In my new "hello world" EJB/JPA app, I always get "Connection closed" errors on my first query, and frequently (though not always) when deploying the project. I must have something configured incorrectly, and I'm hoping someone can give me suggestions on where to look.
Windows 7 64-bit
Eclipse 4.2 (Juno) 64-bit
Java 1.6.0_33 64-bit
JPA Generic 2.0
EclipseLink 2.4.0 - Juno
Internal GlassFish 3.1.2.2
Microsoft JDBC Driver 4.0 for SQL Server (sqljdbc4.jar)
Microsoft SQL Server 2008 R2 (SQLEXPRESS)
I'm using a connection pool (through JTA) that I created using the GlassFish admin page with the default settings. "Ping" succeeds. Here is the error from the GlassFish log:
