jexcel - no such file or directory

[George Simone]

I have the code below which is working fine when running on my local computer (local computer has myEclipse and running JBOSS):
Workbook w = Workbook.getWorkbook(new File("c:/temp/file1.xls"));

When I deploy the application to our test server, I get an exception:
c:/temp/file1.xls (No such file or directory)

Do I need to specify the path differently when the application is running on a remote server as opposed to running on my local computer server?
