Solution:

Please check VNC server start or not. If down, start vnc and let try.

Step 1 : Login as user root.
Step 2 : export DISPLAY=localhost:0.0
Step 3 : xhost +

Note :Before settting the DISPLAY check the XML file in APPL_TOP/ADMIN and inside the xml file see the parameter DISPLAY = “hostname:0.0″ or some thing . this shold be same as when we give echo $DISPLAY

Oracle E-Business Suite (Applications 11i) depend on the VNC services to generate the PDF report output. It was a security concern, thus do work with the security audit team before starting up the VNC server.
