Under Struts 1.1b, you could probably use the same approach that is used
to store ActionForm properties in a map.
private Map values = null;
public void setValues(Map values) {
this.values = values;
}
public Map getValues() {
return this.values;
}
public void setValue(String key, Object value) {
getValues().put(key,value);
}
public Object getValue(String key) {
return getValues().get(key);
}
