Hello everybody.

I have a little question about passing Structure between Java and Native : I noticed that the fields must be declared in the same order in both side.

For example:

Java = public class TestStruct extends Structure { public int fieldA = 1; public int fieldB = 2; public int fieldC = 3; }

C++ = typedef struct TestStruct { int fieldA; int fieldB; // same ABC order in both sides int fieldC; } TestStruct;

Is there a way - other than avoiding structs - not to rely upon the field order ? I mean that I cannot know the order of both sides and thus it prevents me - for now - from using JNA.

Any ideas ?

Regards,

Nicolas
