Description bwl 2007-03-14 02:08:20 UTC 
I attempted to use the New->Entity Classes from Database... wizard with Netbeans
6.0 milestone 7 and it failed with an exception.  From the messages.log:

INFO: Unexpected error while generating the RgProject entity class.
java.io.IOException: Unexpected error while generating the RgProject entity class.

The RG_PROJECT table that the entity is being generated from is as follows:

desc rg_project;
 Name                                                                     Null?

   LONG RAW

I'd guess its the long raw column that is giving it grief since that is what
would translate to byte[].
This was in an Oracle 10g database.
