MDG Transformation - Invoke Java from template?

[rjh]

Would like to invoke my Java code from within an MDA code generation template, is there a simple way to do that?

AFAIK you can only invoke AddIn methods from transformation (or code generation) templates using the EXEC_ADDIN() macro.
You can write an AddIn using Java of course, but I pesonally would prefer C#.

Thanks for the quick response!   Found the documentation under Function Macros.

Unfortunately it's not possible to write an EA add-in using Java - it's a known limitation of the API.  Java can only be used to access EA as an automation client.  There is no way I can think of that you could invoke Java code from a transformation template.  As per the previous suggestion, I'd suggest writing an add-in using C# based on the examples that are available.

I need to access Java APIs.  I presume the way to do this from C# would be to invoke a separate process such as exec and pass parameters thru a CLI.

Hi, I would like to make use of this topic to ask about add-in development in Java, since I saw that this matter was already addressed.

First, I know about the limitation of using java to access EA's information, but still I have made some research and ended up finding frameworks that says to provide bridging between java and COM, such as:

http://javacombridge.com/

Giving my limited knowledge of ActiveX, COM and .NET platform, I would like to ask if even with the use of these frameworks, creating java add-ins is still impossible? Have anyone ever tried this approach?
