Class loaders

[Abhijit Ghonge]

Hi all,

Is there any java commandline option by which i know what classes are being loaded?

Thanks in advance,
Abhijit.

[Rahul Bhattacharjee]

You can run the program java with the -verbose option.That will tell you what are the classes getting loaded during runtime.
Is that what you want ?

[David O'Meara]

I think it's java -verbose:all but I'll check

[David O'Meara]

drat, I just wanted to be first
