There are probably many ways to get this to work.
First, you have the 2D array of objects. How do you expect the object
to be created given a piece of data from XML?
One way, I haven't tried it, but you have to find out what are the
different object types that will have instances go into that array?
Each of those object type can potentially be a problem by itself.
However, just to keep it short, for example, you have this:
Object [] [] data;
and the instances belong to these:
Class A {
int a;
//get/set
}
Class B {
int b;
//get/set
}
A a = new A();
B b = new B();
a and b are passed into that data array. So, to get Axis to be able
to deserialize the data from A and B, it needs to know it's A and B,
obviously. It's not Axis's problem here.
So, you need to tell Axis A and B are web service types.
2 ways to do that. When generate the WSDL, you can declare them, or
add them in the extra classes.
If you can't manage to do that (you need the latest, non-release
version of Axis I believe).
Another way is to create a fake function in addition to existing web
service functions.
void fakeFunction(A a, B b);
Doing that, A and B will be declared and will be serialized properly.
It's best to move away from that Object [][] in the first place.
I would wrap the 2D array into at least 1 D array of 1 D array:
Class DataList {
AList alist;
}
Class AList {
A [] alist;
}
Class A {
}
Good luck.
