No, there isn't.
In a ZIP pwd-protected file, the pwd is used as
encryption key; if you force (by cracking) the file decompression, you'll obtain senseless data.
You can use:
1)brute force attack (but if the pwd is longer than 6 chars, the time needed is incompatible with human life)

2)A Biham/Kocher algorythm based prog: http://www.unix-ag.uni-kl.de/~conrad/krypto/pkcrack.html
