Challenge: Marshalling a jobjectArray from JNI


Hi everyone,

I have got a DLL file which has been badly affected to be accessed from a
java application (using JNI).

I need to use this file in my .NET application, but canont modify it.


I already could P/Invoke successfully (it seems) the two first methods of
signature: void mymethod();

The problems come with the last one, which return an object of type
jobjectArray (it is an array of java strings). Do you have any idea how I
can declare that in my P/Invoke code in C# ? I guess a simple string[] won't
do..

Below is the .h of the DLL

Your help will be greatly appreciated!
Thanks a lot,

Lionel Reyero
