ECMA 262/Perl 5 regexp support in java

Question

Are there any libraries that supports this regexp-specification in java?

Know the Mozilla Rhino uses this specification, but how can this be implemented in java?

UPDATE:
Found a library called jakarta-oro that supports perl5-regular expression which uses ecma-262.

Answer 1

If Rhino supports it, why not use the Rhino scripting support in Java to use Rhino? Look up JSR-223 , and you can use javascript in a Java application if that's what you need.
