Add-in in Java?

[AlanT]

I have not written an EA add-in before. . . . Can one be written in Java?

I see examples on the web site for C#, but not Java.

Thanks, Alan

Alan,

Yes you can.
See C:\Program Files\Sparx Systems\EA\Code Samples\Java_Sample
for an example.

No you can't.  You can use Java with the automation interface but it is not possible to use it for an add-in.

Oh, I didn't know that

Geert,
           I have requested that this be changed at http://www.sparxsystems.com/cgi-bin/yabb/YaBB.cgi?num=1290035070 (features).  You may want to express your support for this suggested change.

sorry for the question but where is the difference?

The short answer is that we have written code to allow Java to call the EA COM objects by wrapping them with Java objects and JNI calls.  (Actually, apart from a small amount of support code this was generated using EA Transformations and Code Generation.)

The code to allow EA to call into Java is completely separate and although I have my theories on how it can be done, it hasn't been done.
