Servoy Client Hangs at 'Start Repository' since 3.0.2

Classic Servoy

Servoy Client hangs with ‘Start Repository’ in the status bar when launching from a jnlp file on the desktop. Quitting and re-launching several times eventually gets the solution to launch. Here is the contents of the Java console when the client hangs:

This error does not occur in the console when the client launches successfully. Any ideas?

Steve,
did you find the problem, i am finding the same thing. I have a simply login screen coming up, sometimes usually after it has hung and i have restarted it then comes up reasonably quicky, but often when i first go in it hangs and hangs.

I am using a mac server and a mac client.
It allows me to pick the application from the repository and then just hangs.

Did you find an answer?

The solution was to delete the hidden folder named ‘.servoy’. This folder contained files created by the Servoy client that became out of whack. I made a tiny application that finds this folder and deletes it, but I had difficulty uploading it here. Send me an email at steve@dakim.com and I will send it to you and anyone else reading this. I have a Mac OSX and a Windows version of the app. All this application does is verify the existence of the ‘.servoy’ folder on a client machine and deletes it. I cannot be held responsible for any problems as a result of using my application though.
