java.lang.ClassCastException: weblogic.jdbc.wrapper.Blob_oracle_sql_BLOB??

612177Jul 28 2010 — edited Feb 14 2012
Hello. I'm trying to bring back a BLOB object from a PL/SQL procedure. I keep getting a class cast exception when I do it

java.lang.ClassCastException: weblogic.jdbc.wrapper.Blob_oracle_sql_BLOB cannot be cast to oracle.sql.BLOB

I get similar results with oracle.sql.BLOB or java.sql.Blob.

What I've noticed is that when I'm not using a JDBC URL with my AM to do the SQL it does not fail. It's when I change to a JDBC Datasource I get the class cast exception. Any ideas?

Thanks, Graeme.
