Why do we keep raking over the same old Perl v Java question? The original question doesn't even bother to qaulify the question.

Anyway - since the question was asked... Every quarter there is a survey of jobs offered based on actual advertised rates of pay. TotalJobs (a UK recruitment organisation) have compiled the information so that you can plug in your skillset and see what you should be earning. I tried a couple of variations and determined that Perl jobs are being advertised at a higher rate than Java. Obviously different permutations of skills and experience may produce different reusults.
