WebFacing - WAS loggings (was EXTREEMLY slow - update - LOGGINGS)

1) Recompilation
('qibm/UserData/WebASAdv/default/logs/default_server_stderr.log')
I restarted WAS before checking these logs (to clean them first).  From
that point I was able to check when compilation took place.  I just
copied the latest messages but I could see that every time I entered the
'LDTRINVC' application, both recordformats of this DSPF were compiled
again.  Same for 'LDTRRESU'.

2) ERRORS ON PROCESSING
('qibm/UserData/WebASAdv/default/logs/default_server_stdout.log')
I find this "failed to load servlet" strange because the application
seems to function normally.
The 'convert'log in WebFacing shows some exclamationmarks (!) at
recordlevel for all RecordFormats.  Only one RFMT had 2 (!!)'s.  Reason
was that 2 indicators were on the same codeline.  To avoid conflicts, I
checked and changed this one so that only one (!) showed up.  Because
this is our first project and we would have a quick test, we didn't
change all code.  We don't have too, not?



Your message was:
>From the subset of msgs you've provided from the stderr, I don't see any
JSPs that are being recompiled.  These JSPs are all named slightly
different, and so it looks like they are only being compiled once.  Do
you see any duplicates across all the msgs you have in stderr?  Normally
you wouldnt see these messages at all, except it appears the webfacing
JSPs are using a deprecated API and that is why they show up in stderr
for you.

I have also seen the "failed to load servlet" error.  It happens because
one of the generated JSPs is malformed, causing the browser request to
send a bad URL to WebSphere.  It is a webfacing error that they're aware
of, but is on the noise level.

Jim,

RECOMPILATIONS

Yes, JSP's for 2 displayfiles are compiled over and over again.  I found
this in the
'qibm/UserData/WebASAdv/default/logs/default_server_stderr.log'

This is the text:

ERRORS ON PROCESSING?

I also managed to cut and paste a piece of the
'qibm/UserData/WebASAdv/default/logs/default_server_stdout.log'.
1) the first piece is generate while waiting on next screen.  I have
reasons to think this is correct, the panel comes up in an acceptable
time:

----------------------------------
Running basic PageBuilder.jsp Processing Record MENU Running basic
CmdKeys.jsp Screenbuilder reference
com.ibm.as400ad.webfacing.runtime.view.ScreenBuilderModel@2381b1a End of
basic CmdKeys.jsp End of basic PageBuilder.jsp

----------------------------------

2) The second piece is generated while waiting on a next screen.  I
believe there are some errors generated, howerver, display comes up
after a while.
