hi, all.
I am a java developer and i am not familiar with oracle forms 10g.
Recently i had a project about digital signing of web forms(on java). So the idea was: We have applet that runs in the client browser, it uses the JSObject to collect all input fields and it's values from CUSTOM web form and create xml document, that must be signed. This applet is like a lib.
I must do the same thing with a oracle form.
Is this possible: collect the oracle form's items on the client??? The form is custom i.e. unspecified items and count items.
If this is possible the next step is to verify the signed xml on the server. So how does oracle forms work. Is there a server side. What is the architecture? Could the xml be passed to the server and how the oracle form's items must be accessed on the server(i need them to verify the xml).
I will be glad if you could help me soon.
Excuse me for my bad english  .
Best regards.

Well, sir, my client wants this to be done in java, .net and oracle forms i.e. it must work for web projects in java and .net where i use aplet for this purpose. But in oracle forms how could i use only java.
Here is what i must do:
Collect all form item names and values and generate from them xml document(kept in the memory) like this:
<?xml version="1.0" encoding="UTF-8"?>
<form-fields>
<firstName type="text">Svetlin</firstName>
<lastName type="text">Nakov</lastName>
<gender type="select-one">Male</gender>
<maritalStatus type="radio">Married</maritalStatus>
<comments type="textarea">Some comments</comments>
<fileUpload type="file" file-name="Nakov-CV.pdf">
LS0tPV9OZXh0UGFydF8wM...MDE4NV8wMUM5MTQMC0tDQo=</fileUploadCV>
<termsAgree type="checkbox">true</termsAgree>
</form-fields>
This is done on the client side(i.e. i must use some VBean and in it to call method traverse(...)). After that the bean must 'sign' this document and after that the signature (string) must be send to the server and verified there. How could this be done? I managed to create a bean that collects the data and signs it but is it possible to execute java code on the server and how to pass this data to the server?
One more technical question how to debug bean?
I read about this and created this:
<HTML>
<!-- FILE: debug_pjc.htm (Oracle Forms) -->
<!-- -->
<!-- This is a HTML file used for debugging Pluggable Java Components -->
<!-- update the serverArgs parameter to include your test module -->
<!-- name and any other required Forms arguments -->
<!-- Amend references of 127.0.0.1:8889 to the correct server and -->
<!-- Port number if you are using a remote server -->
<HEAD><TITLE>Debug My PJC</TITLE></HEAD>
<BODY>
<APPLET CODEBASE="mnenchev-pc:8889/forms/java"
CODE="oracle.forms.engine.Main"
ARCHIVE="frmall.jar"
WIDTH="1000"
HEIGHT="1000">
<PARAM NAME="serverURL" VALUE="http://mnenchev-pc:8889/forms/lservlet">
<PARAM NAME="serverArgs" VALUE="module=perosnaldataform userid=test/test@xe">
</APPLET>
</BODY>
</HTML>
I use oracle forms 10g. But this exception is thrown(using vista 64):

yes exactly. I almost managed to do that. I have a VBean that collects all fields from a canvas in oracle form and then "sign" them and finally place the result as string in other form field. I managed to do the server side. I.e. i import some java classes from the oracle forms builder and wrap the methods as pl/sql functions and i can call them on some events.
It was quite easy, but the configuration of the oracle forms and other stuff was discusting.
I have another problem now, is it possible to access the applet or the applet context under the form? I need to place some links on my java dialogs popuped from the bean. Do you know how to do that?
Best regards

Of course it is disgusting! Performing an abortion in any world, whether it be the physical, meta-physical or computing world, is disgusting, and that is what you are doing to your form and its data.
Does this mean your are trying to get the form to do a 'read'?
