Hi,
Take a look at <orion>\docs\or-howto.html . Basically, what it tells you to
do is provide the type of the elements in your Collection. With this extra
info orion can generate the correct orion-ejb-jar.xml for you.
Once you have the correct orion-ejb-jar.xml, you can use that and remove the
'items_type' attribute from your code.
