Can you please repost your XML and wrap it with [ code ][ / code ] tags without the spaces and use the preview button to make sure it displays correctly.
It looks as if the strucure of your XML is wrong but I can't tell which fields have just been hidden. The assembly-descriptor elements need to go towards the bottom of the file - not one after each bean declaration.
<ejb-jar> <enterprise-beans> <session> </session> <session> </session> </enterprise-beans> <assembly-descriptor> </assembly-descriptor> </ejb-jar>
Use the correct uppercase/lowercase writing of your abstract-schema-name in your EJB-QL: AUser !
