Request synchronization, short question

[sherkan777]

Hi,
Is any way to synchronize user requests to users session state, or queue each request without using Seam conversation or rich faces queue in components?

I mean somethink in java code like:

public void loginPage() {
 synchronize (UserSession.getSession()) {
...
}
}

or somethink like

@Synchronize(Synchronize.UserSession)
public void loginPage() {
...
}
