Dear Manjula, Under Windows environment, you can use Eclipse to write your Perl code, but it may be problematic to run BioMart Perl code under Eclipse. You may need to run it under cygwin. When your Perl script is ready to run, start cygwin (make sure Perl is installed under cygwin), then 'cd' into where your perl code is located, just run it as 'perl <name_of_the_perl_code>'.
At the beginning of your perl script, you may need to add a line after 'use strict' something like: use lib '/path/to/your/BioMart/installation/lib'; This will make Perl know where to load BioMart modules.

I have installed cygwin and added it to the path. Selected cygwin as interpreter type in my EPIC settings in Eclipse. But, when running, it gives this error, which does not give any information! "An internal error occurred during: "Launching Q1.pl". java.lang.NullPointerException" My coding and Registry file can be found in this page, http://biostar.stackexchange.com/questions/10159/biomart-perl-api-in-windows I don't know whether you can help with this error, but any help in greatly appreciated.
