[NOT TESTED BUT SHOULD WORK FINE]
I would suggest to replace command getList by a plain static java method.
Let's call this method com.acme.xxe.CSSExtension.getList. Let's suppose
this method as 2 parameters:
[a] A boolean which specifies whether it should return a string (tokens
separated by '\n') containing labels or a string containing values
(other tokens separated by '\n').
[b] The element which is the subject of the CSS rule. (May be useful as
a context for building your database query. However this is hypothetical.)

import com.xmlmind.xml.xpath.NodeIterator;
public static String getList(boolean getLabels,
NodeIterator context) {
Element element = (Element) context.next();
...
}
---
The CSS is now:
---
@namespace ce "java:com.acme.xxe.CSSExtension.getList";
...
content: combo-box(labels, xpath("ce:getList(true(), .)"),
values, xpath("ce:getList(false(), .)"));
---
How to use static java methods as XPath extension functions is explained
