That's what I have done at the moment. The
exception trace showed the class version id that it expected the target class on
machine B. I put that as the serialVersionUID in the class on machine
B and it works fine. But I don't understand why it should throw an exception if
not declared as the class hasn't changed and I am using the same jdk on both the
machines.

Subject: Re: Local class not
compatible
Hi,
You should declare
the serialVersionUID instance variable for your
class. Otherwise the id will be generated by java which will be different for
different jdk build. If you use same jdk build in both the machines then this
problem may not come. Try with serailVersionUID. I hope this will solve your
problem.

I am storing a serialized version of a class in
the database.I ran the upload on a machine A, backed up the database
and restored the database on another machine B. On machine B when I try to
retrieve the object back I am getting a SQLException saying that the local
class is not compatible showing two different serialVersionUID's.There is no
difference in the class source between machine A and machine B. I
haven't declared the private serialVersionUID instance variable for the
class (which I should). What's confusing me
is if the class hasn't changed then why am I getting this "Local class not
compatible" exceptions. I am retrieving the object from an Entity
Bean the sql type is set as OID
and the jdbc type as a JAVA_OBJECT. In what cases can I
get this exception apart from the class source
changing?
