Hi guys ?? this might sound disgusting, but considerr I new at the web languages !!!, we have a really big app, with at least 300, 1000 users connected from diferent sites of the country, 300 tables, some of them round up the 1 million records, complex gui .... actually this is a client-server app developed in Power builder, but some of us a giving a try to php (I find it really easy, so productivity is my best argument) in the other hand we're considering java.
we like to ear at some suggestions, the best language, or maybe a mix of them, the best aproach, anything that could help us decide ....
help will be appreciated.....
