Joe,
I appreciate your work and analysis of Java vs. PHP. And I agree, that
they both have their caveates but are largly equal to each other,
syntatically. But you can say that about any C based language.
The use of Java and PHP boils down to far more than syntax. PHP is a
scripting language where as Java is a compiled language that has to be run
in a virtual machine. This make Java (at least in my opinion) slightly
more complicated to maintain and deploy. If I want to deploy a change for
PHP I just have to plop the new script in place, but if I want to deploy
new Java code I have to restart the web server (at least in the case of
WAS and JSP's... I'm guessing this holds true with other app servers as
well for Java).
Also, I know that Java has made great strides in recent years when it
comes to execution speed. But that hasn't always been the case. PHP was
strictly built for the web. Java is adapted for the web. Both are valid
options. But when it comes to code, there are far more PHP sites out
there than Java.
Thanks

Re: Separate buisness and display logic question
Don't give up, Albert.
Despite the pundits on this thread, the LDA is just as valid as any
other tool. These days it has very limited use but that makes it no
less valid, especially as a band-aid while designing a more complete
solution. The problem with band-aids is that they sometimes tend to
stay in place a lot longer than intended, but that's the nature of the
beast.
But don't get disheartened because some folks here complain that it's
"outdated". Remember, some of these same folks advocate PHP as the
language of the future for the platform. I don't know if it's more
ironic that people push a language originally designed to help extend
Perl as "the future" or that they say to use it because Java is "too
hard". Take a look at my recent article on web languages:
http://www.mcpressonline.com/programming/web-languages/practical-web-how-hard-are-web-languages-anyway.html
You'll see that, done PROPERLY, PHP is syntactically nearly identical to
Java except with none of the productivity benefits of a strongly-typed
language. So take whatever you hear on the list with a grain of salt
and remember, properly implemented and DOCUMENTED, the right tool is the
one that best meets your business goals.

Okay, I give up.
In all honesty I don't use the LDA for new development either. It just
seemed that in the case presented it would be a reaonable choice since
the OP wanted access to data that was not being returned to his
program and seemed reluctant to change the parameters.
