You only have the path to Getbcard in your classpath. You also need to 
add the path to Showbcard, so java knows where to locate it. From the 
limited code you've posted it looks as though Showbcard has no package, 
so adding "." (the current directory) to the classpath should suffice. 
Normally the default classpath will include ".", but by overriding it 
with the -cp argument you have removed ".".

I don't use the java command on Windows directly, so I'm not sure of the 
exact syntax of the -cp argument in Windows. In UNIX/Linux it's a colon 
separated list of paths, but in Windows-land the colon may interfere 
with the ":" as a drive letter separator. Check your local documentation 
for the java command, failing that Google should find the answer.
