hi,

i possible have a answer for your problem, because i have the same problem on a jboss 5.1.0.GA

to use actual p6spy you have todo 2 things:

1. add set in spy.properties   useprefix to true
2. add in -ds.xml to the connection-url  the prefix "p6spy:"jdbc:mysql...  (without quotes)

problem behind if you are interessted is the loading mechanism of 
LocalManagedConnectionFactory.getDriver(final String url)

which is not checking the driver-class entered only if real loaded for the first time but afterwards only the url is checked !

// Check if the driver is already loaded, if not then try to load it

if (isDriverLoadedForURL(url))
      {
return driver;
      } // end of if ()


i hope the answer helps, 

br horst
