How can I double-click on a file in Windows Explorer to launch a java app and have the java app read the file that I double-clicked?
I have created a batch file that looks like this:
java QuizCardReader
This java class is actually an enhanced version of the QuizCard app from Head First Java (Sierra and Bates). It reads input files containing question/answer pairs, and I have created some of these input files and given them an extension of ".qiz". I have also associated that extension with the batch file above, so when I double-click one of my ".qiz" files from Windows Explorer it runs the batch file and launches the QuizCard app.
What I would like is for the QuizCardReader class to open and load the ".qiz" file that I double-click. If there were a way to pass the path and filename as an arg to the class, that would do the trick.
Thanks in advance,
Tom

D'oh! I just wrote up pretty much exactly what you're already doing. So, second try: When Windows starts your batch file, does it pass any arguments? I'd expect the filename to be in there.

It turns out Windows Explorer passes the filename as the first argument to any apps it launches through extension association.
I modified the batch file to this:
java csci/quizcard/QuizCardReader %1
Now, the batch file passes along any arguments it receives from its caller (Windows Explorer in this case) to my java class. After modifying my class to conditionally handle the arg, it does what I was looking for.

Yes, it works.
Now, I can double-click on one of my .qiz files and when my QuizCardReader starts it loads the .qiz file.
