    Default Integrating JAVA and C#

    Hi all,


    Please I need some help to choose the best way to integrate a main project in JAVA with a program write in C#, this is the situation :

    The main JAVA project is an interface and it will capture an image from a microscope......I will manipulate this image in the C# program ( filters) and then return the manipulated image.


    The methods that i found to integrate : JNI/JNA/WEBSERVICE


    It will work in a LINUX system so another point is what is the best way to go? Try integrate or convert both programs to C++ language (since to use C# we need use MONO and i dont know the compatibility issues that will happen)

    Hey ckask, if you are requiring it to be run on a linux System then I would reccomend two approaches, one would be as you suggested merge both of the programs into C++, the other would be both into Java.

    Before you decide on how you are going to transfer data from one application to another, its probably best that you look at how you data is stored. For example, good luck sending a BufferedImage object from Java to C/C++, as far as I'm aware there is no support for this through JNI.

    Once you have a data structure and you have decided on the approach you are going to take for languages for the applications, then we could discuss a solution to your problem.

    Hopefully, I've given you something to think about here

    I have an idea. Use Java to take the picture from the microscope, hava java export it to "temp.png" (Or any other suitable name) use Java process builder to run your C# app with the image name as an argument, then have C# do its image filter stuff and overwrite temp.png with the new data, finally have Java finish up with the complete image.

    Use webservices, that will solve your problems just fine and be cross platform compatible for you as well. Avoid JNI if possible.
