Hi Collin,
How about a derived getter for use by the web services? Here's what I mean:
public class ProgramVO {
// programID is in here somewhere.
// List of ProgramActivityVOs
private List activities;
public List getActivities() {
return activities;
}
public void setActivities(List activities) {
this.activities = activities;
}
/**
* Derived getter. See getActivites().
* Note: I did not compile this; it's just for illustration.
* Probably could be more efficient, too.
*/
public ProgramActivityVO[] getActivitiesAsArray() {
final ProgramActivityVO[] result =
new ProgramActivityVO[getActivites().size()];
for(int i = 0; i < getActivites().size(); ++i) {
result[i] = (ProgramActivityVO)getActivites().get(i);
}
return result;
}
}
This way, iBATIS can give you the List, and you can give Axis the
array it needs by calling getActivitesAsArray() instead of
getActivities().

I'm not sure if I follow. After looking over the <iterate> tag, it
looks like it is only for adding dynamic SQL *into* a select
statement. I am looking for a way to get data *out of* a select
statement and into a Java array.
Do you have any examples or links of what you mean?
