Thanks, Ralf. I would have never guessed it myself. I changed ejb name in descriptors
from Order to OrderEntiry, and perhaps JBoss
changed table name respectively and the process went a bit further. Now it complains
about some id to be null. Since I have no such
field name, I suspect, it means primary key. But it is also not null, being
initialized on construction. What kind of id is null and
why? May be date is also a reserved word?
----------client call -------------
OrderRemote remote = home.create();
------------primary key field declaration in entity bean implementation---------------
public Date date = new Date();
---------------ejb-jar.xml ---------------------
<entity>
<description>All information of committed order</description>

Order is a reserved word in SQL. Try to give your table another name (through
jaws.xml).
