Scott,

I started looking at CAY-1024 patch, and came to a conclusion that there is a simpler and more consistent solution. Instead of Cayenne failing over to DriverManager in 'setDriverClassName' (which arguably can return a driver with a different class name that does not match the method argument, hence creating confusion), can you simply set the driver class name to NULL. 'getConnection' method then will consult DriverManager and return the driver you specified.

Could you check that it works for you?

Thanks
Andrus

I am using a special wrapper around my Driver so that I don't need to
have the jar on the classpath. This trick clashes with the
DriverDataSource class. Instead of failing immediately if the class
doesn't exist, it might be prudent to check with the
java.sql.DriverManager first - or, heck, even go there first - after
all, that is the standard way of obtaining a Driver.



Regards,

Scott
