Hi,
I'm just evaluating Hibernate at the moment, and am trying to see if I can get it to work with one of our legacy Oracle database schemas.
The problem I have is that when I try to get a SessionFactory, the following error occurs:
Code:

As you can see, there is an InputStream in my mapping file. This was originally created by MiddleGen, but I modified it as it got the keys wrong. Even before I modified it, the same error was ocurring. Here's a snippet of the mapping file:
Code:
<class name="org.hibernate.auction.model.Message" table="MESSAGES">
<id name="mpRef" column="MP_REF" type="java.lang.String" length="9">
<generator class="assigned"/>
</id>
<property
name="mpBdate"
column="MP_BDATE"
type="java.sql.Timestamp"
length="7"/>
...(other properties)...
<property
name="mbData"
column="MB_DATA"
type="java.io.InputStream"/>
</class>
I have found this question asked a couple of times on this forum, but in neither case was an answer posted.
Could anybody please shed any light on this?
Thanks in advance,
Matt
