Printing java layer error stack in a custom module!--Experts, please reply!

Question

Hi to all OAF experts,
We are in a process of making a fully customized module, which is integrated with OM and other modules, and takes the place of Quoting module. There is beasically a custom module which takes the place Quoting module in Apps in Order to cash cycle. Now in the final page of this module where we submit the quote, we need to through the entire Java layer error stack, similar to what is done in stanadard quoting module. There they use AOLMessageManager class for this purpose. But since quoting module is in JTT/JTF framework and our custom module is in OAF , we were looking for alternatives.
I was going through oaf doc and i found a class called OAExceptionUtils, which contains a method called processAOLJErrorStack(ErrorStack)
As per the documentation it says --"Returns an OAException representing the error stack populated by the Oracle Applications user session context AppsContext. ", that is exactly what we need. But , when i use this method, i get error stack as null! Any idea y this is happening? Any alternative how to get this done!

Hi Mani,
What is the source (technology source) of the error?
This is OAF.In a way we have developed entire quoting module from scrath .I believe you would be embedding the Quoting (JTF) pages on to your custom OAF pages. This is similar to how it is implemented in the Standard Sales module.
We are using same quoting APis to create quote. Our code only goes in JTF tech only while entering in and of configurator.Is your requirement to read the java error stack (JTF Code) from the standard quoting application (embedded in your custom OAF Page) in your Custom page's controller (OAF Code)?
Yes, we can create quotes from quoting as well as from our custom table,the only difference is that if you create aquote from quoting, it does not updates our custom tables. We want to throw the same java error which quoting throws, while submitting a code in our oaf controller. It throws even Order management error messages!Any idea how we can go about this..!
