pass nested structs through JNI

[jobs239]

I need to pass a nested struct as argument to JNI function e.g.
struct A {
int a
struct B
}

struct B {
long b
struct B * next
}

What is a good way to do this. I think I can use GetFieldID and
SetField for each field but since the structs are big its very
cumbersome.

Should I just pass a string of values and compose this data structure
on the java side. What other options do I have?

A good way to do *what*?

It's far from clear what you're trying to do exactly. GetFieldID() etc
are for accessing fields in Java objects, but those C structs cannot
be fields in a Java object.

When you say "JNI function", are you referring to native methods,
parts of the JNI API, or C functions in general?
