the eclipselink tries to connect, and fails, and then connect and fail, and just get connected in third time.

>> [EL Finer]: 2011-02-09 16:54:49.156--DriverManager connect failed, trying direct connect.

EclipseLink first tries to connect using standard JDBC DriverManager, if this fails, then it tries to directly connect to the driver, this works in your osgi environment.

The first connection fails because in OSGi Drivermanager cannot see the driver class. You should be able to just ignore the error.

You may wish to look into EclipseLink OSGi support.
