[OJB-developers] ERROR: Server configuration denies access to data source

[<ri...@ya...>]

Hello,

Since OJB is performing REALLY slowly, I tried to add the next tag to my =
repository.xml file:

  <class.proxy>dynamic</class.proxy>

in every <ClassDescriptor> tag.

All my objects implement an interface, so this theorically should work =
fine.
That's the only thing I changed in this file, and now I'm getting this =
strange exception:

After a LOT of these messages: =20

[DEFAULT] WARN: problems with platform =
ojb.broker.platforms.PlatformMySQLImpl:
ojb.broker.platforms.PlatformMySQLImpl
[DEFAULT] WARN: OJB will use PlatformDefaultImpl instead



Do you have any idea of what's might the problem be?

Besides this, how can I make OJB perform faster?


Thanks in advance!
