Hello,

we have a forms application and would like to run it on a windows 2003
terminal server, but the user experience is very bad. When the user
types the letters appeare on screen slowly.
We have Jinitiator 1.3.1.30 installed.
Does anyone know a solution ?

Thanks
Andreas

Found this (for what it's worth):

The problem is caused by new 2D and 3D functionality in Java 1.3 (which
is used by JInitiator). It was not bugfree at that time in combination
with certain graphical cards and drivers. You can solve this problem by
tuning this functionality off by the next parameter in de JInitiator
console:

-Dsun.java2d.noddraw=true

It works perfect at out company and we don't have issues anymore with
popping-up characters seconds after you type them.


Maybe you should stop using jinitiator at all (the latest forms versions
don't seem to need it anymore)

I tried this months ago but it did not speedup. Maybe It was not exact
this parameter. I will retry.

No. The people that wrote the apps tested them with java without
jinitiator, but some forms triggers don't work.

Thanks for the info. An Oracle consultant told me lately that jinitiator
was not needed anymore, but indeed, I remember from the old days that
forms could behave very differently when used without jinitiator.

The real problem here is roundtrips to the server with every key
pressed. It's like the browser telling the server: "This key was
pressed, what should I do?" and the server replies: "Show the character!"


I vaguely remember a trick to circumvent this, but working with forms is
quite a long time ago for me. I'll try to find it in my long-time-ago
notes.....

I'd really appreciate that.

Thanks
