Hi there,

I have installed the servoy server in a Mac OS X V10.4.9 machine.  
Previously I had issues starting up the sybase repository but I ignored sybase now and using MySQL for the repository. So that is not my issue anymore.

I have configured to autostart the Servoy server. That seems to work fine. But I never was able to get to the servoy client launcher page. I just got a blank page. When I checked the log I got the following messages:

Please help!

Hi Hameed

I am having precisely the same issues having upgraded to Servoy 3.5 rc3 yesterday - essentially localhost:8080 is now a white screen and the web client that was working is no longer ! - which is pretty typical as I need to demo it this morning ![:(]( "Sad")

Setup:  
Mac 10.4.10  
Servoy 3.5 rc3  
Repository MySQL (Sybase wont work either !)

I have re installed Servoy from scratch, re started the machine several times and to no avail - any ideas from anyone are more than welcome !!!

Cheers  
Gordon
