Thanks for the suggestions, really appreciate it! I've tried using pack but the returned data type still doesn't match that required by the web service, regardless of byte order. I get the error org.xml.sax.SAXException: Bad types (class [B -> long).

So far, the only case where I don't receive the "Bad types" error is when I supply an integer greater than 2,147,483,647, which is the maximum value of a 32int. It seems that Perl is dynamically assigning the size of the integer depending on the value and I have no control over it. The web service, on the other hand, is in Java, and doesn't seem to accept anything other than the long that it demands!

I guess I will explore other options to avoid this challenge.
