JToolBar from XML
E are trying to generate a JToolBar from XML Files. Unfortunatel it's not working and we have no clue why not. Could someone take a look at the code and please give us a hint a what we are doing wrong? We do the same thing with a JMenu and that is working.
Example XML file:
<?xml version="1.0"?>
<jmenu caption="Wijzigen">
<!--<jmenu caption="Exit">-->
<jmenuitem caption="Therapeut Wijzigen" action-class="actions.Therapeut.TherapeutWijzigenAction" imageurl="images/icon/therapeutwijzigen.gif">
</jmenu>
XMLParser file:

treeWalker(doc.getFirstChild(), bar);

catch(ParserConfigurationException e)
