HI

I am new to Java and would like to use a Delphi form in my Java project.

I looked at the JNI route, and the latest JNI.pas libs are a bit old and I don't know if it is compatable with Java 6.0.

I then looked at JNA and in a short space of time could launch the Delphi form from a Delphi win32 dll and set callbacks to the Java application and could get feedback from the Delphi form in the java out put.

I was very impressed with JNA , and the work involved was easy to implement and to understand.

Then I hit a brick wall.

I created a JFrame with a few JButtons and JLabels to launch the Delphi window with and to reflect the data in the JLabels that was received in the callbacks from the Delphi Window.

I did not work. If I show the Delphi window modal from the dll , it behaves very nice , it (the Delphi Window) updates and repaints , but now , data is received in the Java Form for display , when the Delphi Window closes the callback data gets to the Java window.

So the next step is to show the Delphi window not in modal , and then it seems that the Delphi window is hanging , its non responsive , does not repaint and does not want to close.

What is happening here?

Can anybody shed some light on this?

I really would like to get this working as a interim solution, while we get all our legacy software over to Java.

The Environments I used is the following"

Java :

JDK 6.0 Update 5

Netbeans 6.1

Delphi:

Delphi 7.0

Operating System:

WinXP SP 3

Thanks in Advance
