BLOB cutted when I save

Hibernate version:

Hibernate 3

Mapping documents:

<property name="contenidoDocumento" type="blob">
<column name="CONTENIDO_DOCUMENTO" />
</property>

Code between sessionFactory.openSession() and session.close():

Session sess = sessionFactory.openSession();
Transaction tx;
tx = sess.beginTransaction();
sess.saveOrUpdate(instance);
tx.commit();

Name and version of the database you are using:

Oracle 10g

I'm triying save an BLOB but when I execute the sentences below, the content saved is cutted and only saves a bit of this one.

The estrange is that before to save, the lengh ot the Blob is the correctly, but, for example a blob with length 620352 only saves 853 characters.

The segment of code that catch the data is the next one:

Code:

Authenticator.setDefault(new MyAuthenticator());
                  
URL url = new URL(urlAnexo);

InputStream ins = url.openConnection().getInputStream();

BufferedInputStream bufferedInput = new BufferedInputStream(ins);
                    
int iStr;

ByteArrayOutputStream boe = new ByteArrayOutputStream();
                    
int iu=0;

while((iStr = bufferedInput.read()) != -1){
   boe.write(iStr);
   iu++;
}

boe.close();

byte [] bb = boe.toByteArray();

Blob blob = Hibernate.createBlob(bb);

/* This is the Blob that I save*/
pubFilaDocumento.setContenidoDocumento( blob);

}

I don't know, if there is something similar in oracle, but I faced a problem like this on MySQL. I had to set the packet-size of my database to solve it. Hope that gives you a hint.

Mi mmerder,

I've tried, but the happens the same. I want to believe that the problem is with the drivers, but I going to prove another solutions, if someone works I'll post it here.

Yhanks

Which driver are you using? Can you take a look at https://svn.jboss.org/repos/hibernate/c ... bTest.java ? All the three test methods on this class passes for Oracle 10g, using the driver version 10.2.0.2.0.
