when deserialize array in custom datatype

           Summary: when deserialize array in custom datatype
           Product: Axis
           Version: 1.1beta
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Serialization/Deserialization
        AssignedTo: axis-dev@xml.apache.org
        ReportedBy: ottawausite@yahoo.ca


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?
