RE: beans and JSPs and stuff... -- JAVA400-L

Thanks, Dan, for the comments!

And yes, this is primarily a Java forum, but since at this point I think Java 
for the AS/400 revolves primarily around presentation, I've felt that 
considerable latitude in discussing CGI is merited.

I do have a question... from my understanding, while Perl is definitely a CGI, 
I was given to believe that it's not really OO.  In fact, I thought that Python 
was more OO than Perl.  Perl is an acronym for "Practical Extraction and Report 
Language", and is primarily a text processing language.  As such, it's 
perfectly suited for CGI processing, which is really little more than throwing 
strings around, when you get down to it.  But I didn't think that it supported 
inheritance and polymorphism and all those goodies.

It was my understanding that Python is the true object-oriented scripting 
language, using inheritance and polymorphism.  Not only that, there is a 100% 
Pure Java implementation, JPython, that should be able to run in any webserver. 
 But that remains to be seen.

The reason I bring it up in this forum is the fact that one of the uses of 
Python is to quickly prototype web applications which can then be translated to 
Java.  It seems possible that Python might be a viable way for we in the AS/400 
community to quickly test certain capabilities and techniques, and then 
translate them back to Java.

I'd be interested in hearing your take on this.  Of course, we might quickly 
revert to something way off-topic, so don't be surprised if I take the 
discussion offline <smile>.

P.S. Just as an aside, there is (or was) an unsupported Perl interpreter for 
the AS/400 - I'm not sure what it's status is these days.

>First, thanks for the insight into JSP.  I have written servlets and ASP.
But I have not been involved in a shop or project were there is distinction
between content development and programmers as it were.  They have usually
been one in the same group.  This is helpful in looking at building
interfaces that can distinguish the two.

Second,  I would like to distinguish there is a difference between CGI and
OO.  Perl is OO and CGI.  From inheritance, instantiation, polymorphism, and
encapsulation.  I do not believe there is a Perl interpreter for the AS/400.
This gives the appearance that CGI is not OO and only good as the host
language being called.  Which for the AS/400 would be a non OO language.
Therefore Perl and CGI can be built upon in classes on other platforms (
mainly Unix derivatives and  Win32 ) using CGI.pm.

These classes can be built using any number of aesthetic approaches to
reading data and displaying it with CSS inline or called.  As with any OO
these classes can be packaged by differentiating data calls from the
presentation layer.

Thanks again for the enlightning discussion.  Sorry I know this is a Java
forum.
