Subject Axis can deserialize custom array?
Date Sun, 15 Dec 2002 02:19:06 GMT

 

    hi:

    I changed the sample code of Encoding, and added another class(DataNew) to 

the class(Data).

   It works fine - can serialize and deserialize correctly.

   Class A{

     Class B;

                 }

   But after I changed the class(DataNew) to DataNew(array),

  Class A{

   Class B[];

   }

 

  the deserialize dosen't work correctly, every time I got the same mistake:

It seems that the derialization class of DataNew, always look - "item" in the struct

of DataNew,. But these is no definition of item in the class, so program will always

fails here.

 

So any one can give some ideas about how to handle the array deserialize in custom \
datatype?

or show me some sample codes.

BTW, I just copied the dataser.java file to datanewser.java and changed the 

"data" to "datanew". I need other changes?

 

 

thanks in advance!

 

David
