I have been using JDK 1.4 for my application. I have serialized objects stored in the database as blobs. I am updating my application so that it now requires JDK 1.6. When I try to access the serialized objects in the database, the application throws an UnmarshalException. Is it not possible to access these serialized objects once I update the JDK from 1.4 to 1.6? Thanks.

Are you using custom SerialversionUID. If not then try with that or else try serializing and de-serializing some Exception class object.Even exceptions are already serialized because of the fact that Throwable interface is Serializable.
