Re: Local class not compatible

[Sachin Pandey]

ya the classpath settings are exactly the same on the two boxes. to my knowledge the serial version UID for the class is independent of everything including the jdk version. Am I right ?   Cheers Sachin Pandey NUIX Pty Ltd Level 8, 143 York Street, Sydney 2000 Phone: (02) 92839010 Fax: (02) 92839020   Disclaimer: This message is intended only for the named recipient.

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?    Cheers Sachin Pandey NUIX Pty Ltd Level 8, 143 York Street, Sydney 2000 Phone: (02) 92839010 Fax: (02) 92839020   Disclaimer: This message is intended only for the named recipient.
