Summary: Oracle BLOB and byte array
Initial Comment:
I have tried different way of getting attention but
without success. So I try here.
I didn't get any responses on the previous post and I
have tried JAWS mailing list and still no response.
I do suspect there is a bug or a config problem
somewhere. Anyone?

Subject: Fw: byte[] fields with oracle blob problem
I post this on the JBOSS list and got no response, so
I thought I post it here.
Anyway, I kind of got it to work but with the
following HACK in the JDBCCommand.java and change the
JAW mapping for java.lang.Object to BLOB.
<mapping>
<java-type>java.lang.Object</java-type>
<!--
<jdbc-type>JAVA_OBJECT</jdbc-type>
-->
<jdbc-type>BLOB</jdbc-type>
<sql-type>BLOB</sql-type>
<!-- Change this from BLOB to RAW(255) if you know your
serialized object will be <= 255 bytes -->
</mapping>
if( bytes == null ) {
result = null;
} if (destination == byte[].class) {
result = bytes;
} else {
// We should really reuse these guys
ByteArrayInputStream bais = new
ByteArrayInputStream(bytes);
// Use the class loader to deserialize
try {
ObjectInputStream ois = new ObjectInputStream
(bais);

Subject: byte[] fields with oracle blob problem
I am having some problems using byte[] field with
Oracle Blob.
I have an EJB with a field id of type String and bytes
of type byte[].
I found that there is 2 problems:
1. if the bytes field is null during creation you get
exception of 'Invalid column type'.
2. if you sucessfully 'inserted' something in the
Blob and subsequently re-deploy the bean to retrieve
the field you get a CorruptStreamException.
I had a look at the source. The first exception is
cause by setNull on a JAVA_OBJECT type. And the
second exception is caused by trying to read in a byte
[] as Java Serializable object.
I had this problem in JBOSS-2.0-FINAL but I thought it
was fixed in JBOSS-2.2.1. Anyone?
Any help is appreciated.
Kar
