Summary: Deserialization broken in JBoss 3.01
Initial Comment:
Win2000 operating system
MySQL or MS SQLServer 2000 databases
mapping in standardjbosscmp-jdbc.xml (same as in 3.0)
for mySQL
<java-type>java.lang.Object</java-type>
<jdbc-type>JAVA_OBJECT</jdbc-type>
<sql-type>LONGBLOB</sql-type>
<java-type>java.lang.Object</java-type>
<jdbc-type>JAVA_OBJECT</jdbc-type>
<sql-type>IMAGE</sql-type>
Repeat scenario
Having CMP2 entity bean with one Object atribute.
Call setObject works fine and store as a Blob in
database.
When trying to retreive after, failure happens.
Stacktrace attached below
*Notes:
1. Serialization and deserialization doing only with 3.01
version of JBoss
2. Not trying to deserealize old blobs (I am aware of it
can be not supported and compatible with earlier version
of JBoss)
3. This functionality and same code works fine with
previous JBoss 3.0 version, but it is broken in 3.01.
Thanks

We are using Oracle and map a String[] to a Blob and we do get the same exception.

I don't use MS SQL Server, but I'll see if this works with
my databases. It may just be a SQL Server bug.
