Harshad,
Of course the executable then is /opt/eclipse/eclipse. That's marked
with chmod +x for all groups? Is that what you specified as the
absolute Exec path of the .desktop? You're trying to run from the shell
it seems. What's the value of the PATH variable? If you say "which
eclipse" is it finding one at all on your path?

Harshad,
Does running /opt/eclipse/eclipse fail the same way? Does running ls
-sail /opt/eclipse/eclipse indicate that it has execute permission?
