Currently most (if not all) of the string properties use javax.xml.bind.annotation.adapters.CollapsedStringAdapter. As a quick fix I would propose to extend it, e.g. public class ManagedConnectionStringAdapter extends CollapsedStringAdapter | { | @Override | public String marshal(String v) | { | return super.marshal(v); | } | | @Override | public String unmarshal(String v) | { | v = super.unmarshal(v); | return v == null ? null : StringPropertyReplacer.replaceProperties(v); | } | } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4177422#...
