I believe the problem is this: cocoon.request.get("q") returns a
java.lang.String, not a JavaScript String. Then you try to call the
'replace' method on it; java.lang.String does have a 'replace' method, but
it takes Java char primitives as its arguments. Rhino tries to convert
your RegExp into a char (or Character) to fit the method signature but
cannot, hence the error message.
What you need is to convert the java.lang.String into a JavaScript String
before calling the replace method:
value = String(value).replace(/\s*((\S+\s*)*)/, "$1");
You might also be able to use the java.util.String 'replaceAll' method
which takes a regular expression as its first argument, but I don't recall
off the top of my head if it supports $1 substitutions in the second
argument.
