Hi all, i started a new enterprise application with many servlet which simulate a web site for student for the exam prenotation and so one. Sometimes on running the project it works all good, sometimes, as in this case, after the correct login, the server show me this message:
well according to the hibernate's doc this is what is happening:
"This exception is thrown when an operation would break session-scoped identity. This occurs if the user tries to associate two different instances of the same Java class with a particular identifier, in the scope of a single Session."
you will have to provide more code in order to let us identify your problem.. :-)
