first question - Blackberry/Eclipse error

[itp]

I am new to this environment... and here is my first stupid question.

on Project Build I get the following error:

error: cannot read: C:\Users\itp\workspace\*.java

I am using Eclipse.


Build Information
I have set my Working Directory as:
C:\Users\itp\workspace

Build Location:
C:\Program Files\Research In Motion\BlackBerry JDE 4.5.0\bin\rapc.exe

Arguements:
${build_project} -quiet C:\Users\itp\workspace\*.java import="C:\Program Files\Research In Motion\BlackBerry JDE 4.5.0\lib\net_rim_api.jar" codename=C:\Users\itp\workspace

In Resource box
Path: /FirstBlackBerryProject
Location: C:\Users\itp\workspace\FirstBlackBerryProject


directory C:\Users\itp\workspace exists and my projects are in fact in here.
Actually java source is in
C:\Users\itp\workspace\FirstBlackBerryProject\src


I setup environment based on this page.
