I remember that thread -- the generated Java code was "Slow & Ugly". Someone (maybe me), posted that strong typing in CFML would allow the CF parser to generate better Java code. > InLine Java Code. > If this ever happens, ideally..

I think you could get an interface between no-typing and strong typing I think you would be more easily do develop and test the parts of your program that you needed (or decided) to code in Java. The inline code likely would be more efficient that CF parser generated code, so yes there would be a performance gain (when warranted). You might be developing a routine that will be ultimately deployed as a separate Java program (invoked with cfobject) -- it could be more convenient to develop and debug the Java inline, along with the CFML. The dbMetaData example illustrates one advantage of inline Java. Say you want to change the program(s) slightly so they return a list of db tables, and the columns within each table. On the presentation side, you want to display the combined list in a select box. Here' s what you do, presently: 1) display the Java source 2) modify the Java source. 3) save the Java source 4) switch to a CLI window 5) compile the Java source 6) switch to the CF source 7) modify the CF source 8) save the CF source 9) switch to a browser window 10) invoke the cf template Here's what you would do with inline Java 1) display the combined CF source with the inlineJava source 2) modify the inline Java source. 3) modify the CF source 4) save the combined CF source with the inlineJava source 5) switch to a browser window 6) invoke the cf template Now, you might say "You only save 4 steps!! -- but that's 40% of the steps. and they are repeated many times. You would be eliminating 40% of the interactions, 40% of the distractions, 40% of the opportunities to make a mistake. It means productivity! I hope this helps answer your question -- I really don't under stand what a helper/model class is, yet! As an aside, does Java recognize a construct similar to a hash or a CF Structure, that could be passed between CFML & Java. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Archives: http://www.houseoffusion.com/cf_lists/index.cfm?forumid=4 Subscription: http://www.houseoffusion.com/cf_lists/index.cfm?method=subscribe&forumid=4 FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Signup for the Fusion Authority news alert and keep up with the latest news in ColdFusion and related topics. http://www.fusionauthority.com/signup.cfm
