Some of you guys can do this, right?
I am trying to learn it - but fucking hell it's difficult.
Obviously I've looked elsewhere, but no one has quite got the same problem that I can just rob the solution from.

I am using Pentaho and need to create a java filter that then creates two data streams.

Basically, I am trying to remove all products which have a release date in the future.

Something which would logically be:

IF RELEASEDATE IS > PRESENT DATE THEN THIS IS TRUE
OTHERWISE FALSE

The true stream would just end up in a dead end so I can remove them from the database.

dates are currently in dd/mm/yyyy - but dates when I get them out of javascript have the fucking time with hours minutes and seconds involved. I don't need that.
I don't really know what I'm doing. Is this simple? Is this hard?
