Couldn't converted the type from object to array.

           Summary: Couldn't converted the type from object to array.
           Product: Axis
           Version: 1.1
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW

         Component: Samples
        AssignedTo: axis-dev@ws.apache.org
        ReportedBy: tritreechina@hotmail.com


I wanted to convert the data type from object to String[] . I got the exception 
just like following: 

Exception in thread "main" java.lang.ArrayStoreException 
       at org.apache.axis.utils.JavaUtils.convert(JavaUtils.java:432) 
       at ArrayClient.main(ArrayClient.java:50) 

JDK: j2sdk1.4.2_03 
tomcat: 5.018 
Axis: 1.1 
system: windows 2000 server(chinese) 


What can I do? 
Thanks at all.


Here is the sources:
// File : AddressService.java

public class AddressService {
  private int[] id = {111, 222, 333};
  private String[][] addressBook = {{"Street 11", "London", "UK", "34534"},
                                    {"Lane 4", "New York", "USA", "53457"},
                                    {"Lane 5", "LA", "USA", "67635"}};

  public String[] getArray(int id) {
    for (int i=0; i<addressBook.length; i++) {
      if(this.id[i] == id) {
        return addressBook[i];
      }
    }
    String error[] = {"id not found!"}; 
    return error;
  }
}
