Hi,
In order to use the signed screen sharing jnlp, I unpacked 4.0.8 and copied the
configuration files from my nightly build setup (which was around 4.0.5). But I
keep getting the “loading” animation and just the chat is shown. And if I try
to send something in the chat by pressing the send button, I get the error
below. What could be wrong?
Also, do I need to do some migration in the database when upgrading to 4.0.8?
Thanks in advanced.
The error:
ERROR 07-11 03:36:55.854 o.a.w.DefaultExceptionMapper:170 [0.0-5443-exec-8] -
