Re: [WEB400] WebFacing project status...

Buck,

I don't know what the JspBatchCompiler is, but Tomcat comes with a
precompile script. I haven't tried porting it to the iSeries, but I
don't
think it would be very hard. It looks like it would even target your
WAS
directories if necessary. The scripts to look at are jspc.sh and
jasper.sh.
You would want to use that to compile and then run a CRTJVAPGM against

the class.

Also, if you compile your OPM program with OPTION(*srcdbg) you will
be able to use the regular debugger. When you start debug just specify

OPMSRC(*YES).

I have an 820 in house with some L2 cache and the horses to drive WAS.
With
everything straight out of the box I am seeing a first touch of about
6
seconds, and a screen to screen time about 2 seconds.  I am exploring
ways
to optimise this.  The JspBatchCompiler helps some, but it'll only do a
few
hundred jsps before terminating.  Of course, with the new box, we got
WAS
4.0 and so I had to re-learn about WAS.  WAS 3.5 is very different from
4.0,
because 4.0 is the full J2EE version, whereas 3.5 was IBM's best guess
at
what J2EE was going to be.

It's been a rather amazing experience, all things considered.  In my
case,
WebSphere is running classes and jsps created by a code generator
(WebFacing) over DDS and RPG created by a code generator
(Synon/Cool:2E).

Debugging one of these applications is quite difficult from its green
screen
companion.  Because the RPG is OPM, I need to use STRISDB, but because
there
is no physical display, viewing the results depends on the WebFacing
server
and WAS.  If there's a hiccough there, then one needs to delve into the
WAS
debugging magic.

Deployment has been an issue as well.  I can't deploy the full
application;
I get an error in the Admin Console saying it can't find an XML file.
IBM
are working on this one.  I got around that by creating a small war
file of
only the initial screen and deploying that.  Then I export the
individual
objects from the WebFacing tool into the file system created by the
Admin
console for the small deployment.  That has been working for me.

Outstanding items:
1) Optimise generated classes and compile the generated jsps
2) Learn WAS debugging
3) Learn how to package the lot so I can do the
   equivalent of a SAV here and a RST on my
   customer machines.
