I just have noticed it could be a problem.
Do you know any example how to create that serializable proxy using spring?
Thanks.
Regards,
Wojtek.

Your Page (HomePage) contains a reference to your SpeedService EJB. Since
that one is not serializable, your page cannot be serialized.
A possible solution is to inject your ejb (by using for example
@SpringBean). This makes serializable proxies, so your page can be
serialized...

Hi there,
I am working on the project using Wicket and EJB3.0 on Glassfish AS.
I've got such case:
There is a page with some test, using Sateful bean. When you press a start
button, the model using the bean is created, bean is beeing looked up on
each start button pressed. When I change the page and then use back button
and press start button again i get such exception:

The test is going correctly just this stacktrace is beeing printed every
sample is refreshed.
Has anyone had similar case, or idea what is going wrong?
Appreciate any help.
