RealVNC: No configured security type is supported by 3.3 viewer

I`ve been messing around with the idea of writing a mobile VNC client in J2ME lately, and I came across J2ME VNC which is exactly what I’m trying to do. Unfortunately the source is downright ugly, I might add. Anyway, I was trying to make it connect to RealVNC Server 4.2.x, Personal Edition and I was greeted with the aforementioned error:

No configured security type is supported by 3.3 viewer

This is caused by the fact that you have check encryption to be “always on” on the security tab of the VNC Server. Unchecking it will make J2ME VNC connect to the server. I’m pretty disappointed with what it offers. Anyway, happy development.
