Orion 1.5.2 is much stricter about what you can put into app / session scopes. Any objects you want to store MUST be serializable (they didn't have to be in 1.4.0, the 1.5.2 behaviour is more spec compliant).
I think the ResultSet you're using isn't serializable. Try pulling the data out first into your own data structure, and then storing that. -mike Mike Cannon-Brookes :: [EMAIL PROTECTED] Atlassian :: http://www.atlassian.com Supporting YOUR J2EE World > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED]]On Behalf Of Andres Garcia > Hourcade > Sent: Friday, September 28, 2001 11:56 AM > To: Orion-Interest > Subject: OrionRemoteException: Error (de-)serializing object: > > > I have an application (jsp & ejb) running with version 1.4.0, i > am trying to > upgrade the same EAR in 1.5.2 version, but i get this error. > > What i am doing wrong ? > > com.evermind.server.rmi.OrionRemoteException: Error > (de-)serializing object: > org.gjt.mm.mysql.jdbc2.ResultSet; nested exception is: > java.io.NotSerializableException: org.gjt.mm.mysql.jdbc2.ResultSet > > Many thanks > >
