Q: When using putty, SecureCRT, SSH to start SuperMap iServer 7C or SuperMap iPortal 7C service on Linux, such error as "Could not initialize class sun.awt.X11GraphicsEnvironment” or “System environment checking failed” appear on the front page. But it works well when starting service locally. Why?

A. When remotely starting SuperMap iServer 7C and SuperMap iPortal 7C, you need to first log in to the Linux server and run the command below:

(1) X:n&      Start XServer on the n-th screen. n is any integral, e.g. 22, 30.

(2) export DISPLAY=:n.0      Set DISPLAY variable to the XServer of the local machine, and restart the service .
