C:\java\src\thufir\bonjour>echo "err, bog."
"err, bog."

C:\java\src\thufir\bonjour>


The HelloWorldApp.java source file says that it's in package
thufir.bonjour, which is reflected by its path. So that's
correct, yes?

When compiled, HelloWorldApp.class ends up at
C:\java\build\prod\thufir\bonjour which is also correct. Yes?

The name of the source file, the directory structure and
the package names match, so I'm not understanding what
"doesn't have the right name."


thanks,

Thufir
