It is a 4GL to 3GL migration.
So if you want to you can write a generator that takes your Uniface application and generates a Java application from it. Should not take more than 2 years to make such a thing.
Although moving from a data-centric, component based architecture to an object oriented paradigma might cause some issues.
Oh, and don't forget that the Uniface kernel does a lot of stuff for you that you have to program yourself in Java.

If you have a good (and updated) functional description what your application does,

it's the best to take this as a basic project definition and start fresh.

As Theo mentioned: Uniface Runtime does a lot for you in the activation of triggers etc. "behind the scene".

There are ways to translate the FORMPIC into a java screen layout, so if you have masses of forms, it will save you a lot of time.

Alternative: The new ECLIPSE provides a screen painter for JAVA developments, but you have to repaint your screens.

Yeah , I agree that we need to start fresh.. but i saw in export file there is lot of information ..which i felt will help to reduce efforts while converting.

.. you are correct, there is a lot of info in the XML files.

But you need some parser/generator to convert it to some useful code.

A sound understanding of the basics of uniface repository architecture (and formpic in special)
can save you a lot of time preparing some "raw java".

Migration to JAVA, hum hum.

The forum is not about that.

Change to a forum on JAVA solution...

Bye
