Title: Add-in in Java?
Post by: AlanT on November 17, 2010, 02:12:26 pm

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.

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.
