I see 2 solutions at your problem:
1) Let the default value for passivation timeout (0 = means no passivation). In that 
case,
your beans will never be written in the database when no transaction is used.
2) Use a isModified() method (described in your deployment descriptor) that will return
false, so the ejbStore() will not write bean to the database.
Note that you will still have a problem: In the EJBServer, you will not see the new
values that your other application set behind... To avoid this, only 1 solution:
always access database thru EJBServer.
