[News.eclipse.dsdp.mtj] Re: cannot load files from res folder

[Kevin Horowitz <khorowit@xxxxxxxxxx>]

The contents of the 'res' folder are added the the deployed jar and 
available for use when testing the Java ME app.  You need to use the MTJ 
run in order to set the paths correctly and use the Deployed jar.  If 
you have not done this, the images will not be seen.
