Re: Adobe's RIA Technologies

I would like to add this and say that one can also create service programs
by specifying the program type in the compile directive. Eg:

<%@ language="SQLRPGLE" pgmtype="NOASPSRV" options="COMMIT(*NONE)"
modopt="DBGVIEW(*LIST)" pgmopt="MODULE(*SRVPGM) EXPORT(*SRCFILE)
SRCFILE(BJCS_S/QSRVSRC) SRCMBR(*SRVPGM) ACTGRP(*CALLER) BNDDIR(JCCTLH)" %>

Actually CRTICEPGM has four phases:

1) The IceBreak pre-compiler it self
2) ( if needed) the SQL pre-compiler
3) The crtrpgmod
4) And finally the CRTPGM

All the above phases have specific i5/OS parameters which can be controlled
from the initial source which has compiler directives on all levels. Which
kind of compiler is also determined from these compiler directives.

The syntax is the same as in ASPX and JSP ... Ex:

<%@ language="SQLRPGLE" SQLOPT="commit(*NONE)" MODOPT="DEBUG(*YES)"
PGMOPT="BNDDIR(OMIBND RXSBND)" %>
<%
/free
*inlr = *ON;
%>

All other system i programmer has the same need as you. Our solution is
quite forward. Just extend the CRTxxx command with the string in the
compiler directive - no rocket science here ... I wonder why IBM did not
introduce something like that even back on the S/38....

however the CRTICEPGM command is used from within RDi /eclipse if you want

to control the compile phase.

H DEBUG(*YES) dftactgrp(*no)
*T: 1003: Cancel/Complete Orders
*I: QCMPSRC,CRTBNDRPG
*O: BNDDIR(OMIBND RXSBND)
*O: TGTRLS(V5R3M0)

I am probably not your typical IceBreak user as I grew up with calling all
the stdin and stdout API's directly and I have become picky with how much I
like a framework to help me because *sometimes* they get in the way. I can
see how IceBreak would be an excellent solution in making the transition
from ASP/JSP/PHP to RPG+IceBreak.

Thanks for your response,

Hi Aaron , gents ..

The "one-size-fits-all" has never been the idea of IceBreak, rather give
the
user some choices. Many RPG programmers don't feel comfortable with any
kind
of web technologies or frameworks simply because there are far too many
disciplines to learn. So - yes - you can build programs with a JSP / ASP
approach - which are good for quick and dirty stuff and/or educational
purposes. The build in JIT compiler delivers the result, just by

refreshing

the browser page, however the CRTICEPGM command is used from within RDi /
eclipse if you want to control the compile phase.

In "real world web applications" you would also rely on a framework of

some

kind and some tooling to support it. Adobes flash powered Flex is an
excellent choice, however, in IceBreak we did chose to follow the ExtJS
path.

Arron wrote: Maybe you have some application code you can share that

shows how IceBreak can do the things that you are talking about? (i.e.
solid
MVC with extJS)<<

I think I can demonstrate it with a program containing only one line of
code:

The hole idea in MVC is to decouple any of these M, V, C components from
each other. Our solution is to support "data stores" for the ExtJS
framework
- look at the following IceBreak program

SQL_Execute(
I_EXTJSMETA: // A JSON object including metadata
'Select * from product':
numberOfRows:
startingFromRow
);

This returns a partial result set for a paging grid.

IceBreak simply produces a JSON object in the responseObject and returns

it

to the Ext client, which happily renders the grid and allows the user so
use
page up and down using a AJAX request for setting the "startingFromRow"
attribute. This is only possible because IceBreak provides session
stability
for dataset too.

So our MVC model let you do the decoupling 1where IceBreak is gluing the
"V"
and "C" together behind the scenes with JSON ... and you don't even have

to

look at it.

The IceBreak ExtJS component wizards even produce grids, dropdowns and
complete programs.

I suggest this kind of modeling instead of the SOAP webservice approaches,
which in my opinion is to over engineered for this particular job. ? You
need to parse the SOAP, XML ? and you need to provide some session
stability
for the dataset etc?.
