Hi Marc,

First off, the best way for me to debug a controller's output is append the 
following parameters to you controller call:

style=XML&XSL=NONE

So if you have a default param, it might look something like so:
http://localhost:8080/MyController.do?state=MyState&style=XML&XSL=NONE

That will display the output in an XML format that you can browse through 
to make sure your output tree is functioning correctly.

Doublecheck yourself by setting the content for your output and try to just 
output the content via the taglib.  I seem to remember a bug in OutputTag 
where attributes weren't getting displayed properly from a while ago. [This 
is just off the top of my head though]

The other way to go about displaying your information would be to use the 
Struts tags to iteratate through your block and then use
<bean:write name="iteratorName" property="dierOverzicht.dierID"/>
<bean:write name="iteratorName" property="dierOverzicht.DierNaam"/>

At least these are the two approaches that I'd recommend looking into.

HTH!
