Hi Shariff,
The requirements are quite clear. As you correctly pointed out, this is the opposite of the
Lightstreamer DDE Demo, where we implemented a DDE Server in Java that is also a Lightstreamer Client. In your case, you need to implement a Lightstreamer Adapter that is also a DDE Client. For the demo mentioned above, we used
NevaObject's DDE Server library. You might want to check out the DDE Client library on the same page, which you could embed into your Lightstreamer Data Adapter.
Let us know if you make any progress.
