is Perl used in the Java middle-tier

Hi,

I'm a newbie at regexes and a professional java programmer. I've ready
Friedl's book and see that
java.util.regex is missing code assertions and overall can't solve the
complexity of matching, transformation
problems that Perl can solve. Therefore, I'm wondering if there are
companies that are integrating Perl
solutions into their enterprise java applications. Or do they just
struggle with java.util.regex.
