Hi,
I'm using axis2 1.7.0SNAPSHOT and finding two problems.
First when I'm having ArrayList in my class, for example:
public class VEntryData{
protected List<ViewEntryItem> items;
public List<ViewEntryItem> getItems() {
if (items == null) {
items = new ArrayList<ViewEntryItem>();
}
return this.items;
}
}
My service functions look like this:
public VEntryData getVED(){
return ved;
}
public void setVED(VEntryData ved){
this.ved = ved;
}
In this scenario the getVED() works fine and when I do setVED() from the client
I pass a valid list but on the server side I get null for items field.
//========================================================================================
In the second scenario I use plain array:
public class VEntryData{
protected ViewEntryItem[] items;
public ViewEntryItem[] getItems() {
if (this.items == null) {
return new ViewEntryItem[ 0 ] ;
}
ViewEntryItem[] retVal = new ViewEntryItem[this.items.length] ;
System.arraycopy(this.items, 0, retVal, 0, this.items.length);
return (retVal);
}
public ViewEntryItem getItems(int idx) {
if (this.items == null) {
throw new IndexOutOfBoundsException();
}
return this.items[idx];
}
public int getRedLength() {
if (this.items == null) {
return 0;
}
return this.items.length;
}
}
My service functions are the same as in previous case. In this scenario the
getVED() produces the error:
