Hi, I've installed QFlex express and everything work fine except that Qflex doesn't produce charts.
Could someone help me to solve this?

Many thanx.

It was an headless machine, so I had to append
-Djava.awt.headless=true option.

Bye.

on a headless server, u java needs xserver in order to initialize graphical environment for image rendering. before starting qflex, as qflex user export DISPLAY=somehost:0 somehost have to have xserver running. before starting qflex, try executing a command like xclock or xterm. If u get errors, try issuing xhost command on the xserver side to make sure xhost client has permissions. contact support qflex@netflexity.com for more details.
