Hello,
I have installed Eclipse on my PC (Windows 2000 /X86).
jdk 1.4.1 is in the path of my OS (How to give path of another jdk, it
never asks for the same?)
While starting eclipse, it gives error
An error has occured, see the log file.
The log file is of 706 KB.
I do not have administrative access on my PC.
What may be the problem?

Some of starting lines from the log are:
