RE: Making sure...

Agreed with EJB... Beans are definately the way to go... We use Ultradev to
help us with the bean code as well as embedded Java... It has improved our
productivity significantly.  We are not longer writing JSPs in notepad....
We looked at Websphere Studio, but we didn't feel it was as intuitive as
Ultradev... Of course, we have been using Dreamweaver forever...

Remark: 

One problem with JSP is that they are difficult to maintain. The best is
certainly 
not to write logic into a jsp file, but to delegate this logic (mostly
display logic) 
to a bean that is used by the jsp. Therefore, the only code you add to the
jsp is calls 
to that bean. 

If you read the sun blue print papers you'll find some documentation about
this: like presentation 
beans. 

About security: a jsp is compiled on the server, and the client only sees
the generated html 
file. I can't see how you could upload a jsp? You don't upload anything, all
the code runs on 
the server.

I guess I shouldn't be using IBM's examples then.  I'm finding a lot of 
programming flaws in them, like it was written for programmers who have only

done RPGII.  

Why do JSPs scare me?  WEll, we've been through this before on another list,

but it seems to me that it is easier to upload a jsp file that could do harm

(same as a net.data macro, ASP, or anything interpreted) than it would be to

install a compiled CGI object (RPG, COBOL, etc). 

I must admit, I'm working on the servlet example from IBM that reads from a 
browser.  I must have removed half of the code already.  Nasty programming. 
Lots of unneeded "ifs" and "hold variables" to check contions.  yuck.  

I haven't even touched on DB access yet.  Im sure that will be the defining 
moment because it can't be easier than eRPG. :)
