Java DDE

I'm writing a program in Java, that reads data from different
Windows applications, ie. Intouch, Notepad.

In order to do that I've installed a class called Jddeml in
my CLASSPATH. In the description of the class it says:

  Class Jddeml represents Windows DDE object (server or client).
  Jddeml enables Java applets/applications to interact with Windows
  applications and other applets/applications using Dynamic Data
  Exchange Protocol.

The question is : Has anyone experience in using this class?
I've got some problems telling the DDE-server which application
it's going to retrieve the data from, and what data it's going
to fetch.

The source code of the class Jddeml, I found at:


If anyone can help me, I'll be happy.

Thanks in advance!

Why isn't this in the java area?
Java is not the same as JavaScript and not everyone who is expert in one is also either expert or knowledgeable about the other.

why not email the people at www.nevaobject.com. They wrote it.
DDE works using the following Syntax:
To use Reuters DDE in Excel for example and you wanted say, Sybases share price you would do this formula:
The reason it has a single quote is because you are passing 2 arguments 1)SYBS.O the company stock code and 2)LAST - the last traded price. You will have to specify this syntax and NOT just the application name.

Generally you can find out what Topics and Items are available
by creating a formula array in Excel and use the following:
To find out Reuters TOPICS
To find out Reuters ITEMS
