Thanks Emmanuel for your quick response. On setting the VM arguments I was able to run it through eclipse on Linux and Windows2008, but I was not able to run it through eclipse on Windows 7 (32 bit). I am using SweetHome3D-3.7-src. Also I am not still not able to run the jar created through command line. Can you tell me how we can run it through command line. How do we pass the VM arguments on command line. I tried

java -jar SweetHome3D -Djava.ext.dirs=lib:lib/linux/i386

but it is showing an error---
