Questions on oracle forms?!?

Question

Hi, all.
I need some help for oracle forms 10g.
I have some very important questions, pls help.
1) If i have VBean and say this.getCientProperty(Object o). Is this method returning me the value of property specified in the properties palete in oracle forms builder i.e. if i write this.getClientProperty("Name") -> it returns the name of the bean(is it valid for other components like VTextField for example)?
2)Could i call methods from the server on the client and how? I read that server method could be wrapped in pl/sql procedure(could you give mi simple example)?
3)As i understand the only way, that one form can communicate with one bean is with getProperty and setProperty methods, is it?
Thanks in advance.
Best regards.

Hi Francois. First i want to thank you, because you are helping me.
First to say using ugly tags is not a problem, because this xml is only in the memory(it will be nice to be with good tag names but not mandatory).
Here is what "sign" process means:
This process is executed on the client not on the server. So after the xml document is generated it must be signed i.e. with java crypto api and bouncy castle api i create signature from this xml(with algorithms from the api) this signature is like hashcode(String). This string must be passed on the server and there with other algorithms to be verified.
Imagine you have to sign some bank check(represented as web form for example or electronic file) and send it to some person through internet. How could the bank know that this check is signed from you? So i am working to do this possible to sign electronically documents and data. That is the idea. And i created this as a framework like a lib that only needs to be added and used. But our client wants to do the same for oracle forms applications. Unfortunatly i am not oracle forms developer but no body ask me.
I read the how to debug guide but i have some problems and cant debug. I am using vista 64, i don't know if this may be a problem. My College managed to run debug with your guide but i am not. When i hit debug debug_pjc.html every thing is ok. The form is shown but the debuger is not started.
Here is the exception:
