Yes, the value objects implements the Serializable interface.
There is more important informations:
1- This error occurs in all methods that takes an value object as parameter.
2- The client is a
Tomcat 4.1 , when i call these methods from a desktop
application with Swing, this error does not occur (I�m using Tomcat as web container instead weblogic because all the necessary security configuration is running fine there).
3- The value objects in the all sides are the same.
4- The version of weblogic is 8.1 sp2
Will it be another error in weblogic? In the fixed errors list of this
version, a similar error is fixed.
Since now I thank very much the attention.
