Hi Matthias, did you see Harald's quote from the Trinidad docs? I'm including it here again:
<quote> Apache Trinidad is configured with an trinidad-config.xml file. If you need an trinidad-config.xml file then it must be placed in the WEB-INF directory of your web application. This file has a very simple XML structure that relies on the JSF expression language (EL) for flexibility. **** Each configurable property can be defined either inline with a static, constant value, or with a JSF EL expression **** that is re-evaluated on each request. </quote> regards, Martin
