de.espirit.firstspirit.common.IOError:Io error

[novomind]

Hi,

I am trying a pass a serialized object to a service installed on server. Whenever the call to the service is made the following exception is thrown:

de.espirit.firstspirit.common.IOError: Io error in receiving manager call: null - java.io.InvalidClassException: javax.swing.text.DefaultStyledDocument; local class incompatible: stream classdesc serialVersionUID = 940485415728614849, local class serialVersionUID = 7691029896427935656

Since the SerialVersionUID is changed, I recomplied the module and installed the modules fresh on server and restarted the server and services even but invain.

I would appreciate, if anyone could provide some suggestions or pointers in trying to resolve the issue.

Regards,

Ronny.

Hi Ronny,

look at java.io.InvalidClassException: javax.swing.text.DefaultStyledDocument,

it seems you are using different java versions for the server and the client. Using the same version for sending the serialized Object should fix your problem.

It would be safer to not serialize instances from the package javax.swing.
