Problems Converting from Form6i to Forms10g/Reports10g - first experiences

Question

Hello,
We are converting a Forms6i application to Forms10g.
There is one fmb-file with a size of more than 3100kb.
First step and surprise is that after using the
forms migration assistant for converting the file from
6i to 10g the size is minimized and now about 1000kb.
We did not use the migration assistant and opened all
6i files with FormBuilder10g (WindowsXP)
Assuming that the conversion will be done if we are saving the file in form10g-builder.
After doing a lot of chances in the big-fmb file and saving it -
closing the form and opening it - the changes were lost!
(Perhaps because there was more than one crash of form builder?)
My questions are:
- how can i check if the integrity of my fmb-file is ok?
- is the minimum hardware requirement for developing a 10g-FMB file on a PC more than > 256MB RAM/450 MHz Processor?
- for WindowsXP there is a DeveloperSuite 10g PreView -
what does that mean? when will the final version be released?
My experiences are:
- if you are integrating a 10g Report with a parameter form in forms10g: first it does not work - you have to integrate a javabean in forms (encrypted userid in cookie
before calling the report) or the other solution i read was funny with nearly no security (userid in hex in the url).
how can u call a 10g report from the web without writing all your credentials in cgicmd.dat and without having oid (single sign on)?
a solution would be writing your credentials encrypted in a cookie and then calling the report with the parameter form -
but how? if you have never done java before?
- handling with formbuilder10g is much more slower than formbuilder6i: is forms10g written in java?
- you have to do a lot of configuration before calling a report on your development pc.
thx for any comments and tips
ps:
shall i use webforms10g now or learn java/jdeveloper or wait for java.net (=cooperation Microsoft and Sun)? <

Hello Frank,
Thank you for your 9i/10i secure calls to web.show_document solution. I spend hours with it but could'nt get it working. I followed all the instructions from the pdf document. Everything looks fine ( java console output included ) but the cookie isn't created.
I watched the tcp packet for the http header to see if any cookie information was included, but this isn't the case. I switched browsers (IE5 and IE6) and changed their security settings to very low. Nothing seems to matter. Still getting the REP-51018: Need database user authentication error. What am I doing wrong???
I'm running 9.0.4 (10g) forms reports services edition on Windows 2000.
