[JBoss-user] How to do BLOBs in Oracle?

[Luttrell, Peter]

Does anyone know how to get get BLOBs working in Oracle? I need to store some larger pdfs in the db and some of the bytes in the file are causing a causing a problem when stored as a varchar or CLOBs.

 

I'm using Oracle9i and JBoss3.0.4. I have a CMP field of type Object.

 

I have setup my jbosscmp-jdbc:

 

<jbosscmp-jdbc>
    <defaults>
        <datasource-mapping>Oracle9i</datasource-mapping>
    </defaults>

</jbosscmp-jdbc>

 

And the standardjboscmp-jdbc.xml contains this under Oracle9i:

 

 <mapping>
    <java-type>java.lang.Object</java-type>
    <jdbc-type>BLOB</jdbc-type>
    <sql-type>BLOB</sql-type>
 </mapping>

 

I have deployed the 9i drivers we got from oracle. The exact file name is ojdbc14.jar, which i guess reflects oracles new naming scheme.

 

I call the setMyField(Object field) method and sent it a String. Then I call the getMyField method and it returns null. There is not errors in the log files. I had a dba trace my session and it is in fact getting to the db as "update mytable set myfield=:1 where mykey=:2". Is Jboss generating the correct SQL?

 

Any ideas why this isn't working for me?

 

thanks.
