[rules-users] Create kieBase programmatically: WARN "No files found for KieBase defaultKieBase"?

[Frank Langelage]

I'll answer myself:
it's mandatory to use "src/main/resources/" as the base folder inside 
KieFilesystem.
kieFileSystem.write( "src/main/resources/" + fileName,
	kieServices.getResources().newInputStreamResource( is ) );
with fileName = "etc/MailFilter.xls".

Now Apache POI breaks down processing my xls file which works with 
drools 5.5 / JExcelApi:
