1) The WSDL2Java tool has minimal error reporting at the present time.
This is do to the following reasons:
- The tool is fairly new with limited developer resources. We have chosen
to use our resources to add additional mappings instead of issuing messages
for the myriad of unsupported types.
- We may wish to re-write the parsing checking code....so the current
implementation could be considered a first pass at development.
2) As far as the mapping for union, does there need to be a check to make
sure you get the object in the same way that you set it ?
I think we could add this support post beta 2.
public class VersionInfo {
public Object value;
public Object getValue() {
return value;
}
public int getValueAsInt() {
return ((Integer) value).value();
}
public Calendar getValueAsCalendar() {
return (Calendar) value;
}
public void setValue(Calendar value) {
this.value = value;
}
public void setValue(int value) {
this.value = new Integer(value);
}
}

Hi Richard:
We don't yet claim to support union types, so I'm not surprised you got
some weirdness. We should probably (as a minimal first step) be better
about reporting an error when we come across a schema construct which we
don't understand.
How would unions be represented in java? Something like this?
public class VersionInfo {
public Object value;
public Object getValue() {
return value;
}
public void setValue(Calendar value) {
this.value = value;
}
public void setValue(int value) {
this.value = new Integer(value);
}
}
