I can see a couple of ways a script could help:

1. Create a helloworld.bat script (I'm assuming, given the wish to
ignore case, that this is MS-Windows specific) that runs the java
command with the correct spelling of the class name. Users who run the
script could ignore case.

2. Create a general script, javaignorecase.bat, that takes the same
parameters as the java command. It would scan the class path for
classes. If it found one that matches its class name argument ignoring
case, it would run the java command substituting the actual class name
for its class name argument and passing through the rest of the
arguments unchanged.

Personally, I don't like things that ignore case, but that is a far from
universal view.
