Even if the scope is 'session' you will get that behaviour if you do
something like...
<jsp:useBean id="myBean1" scope="session" class="blah.myBean"/>
...
myBean1.setValue(200);
myBean1 = someBean.getMyBean();
myBean1.setValue(100);
// value is now 100
after the forward however, 'value' will be 200. Not looked at the compiled
JSP but would guess that the reference is being stored in the session at
instantiation. To get around it use some sort of copy method- ie
myBean1.copy(someBean.getMyBean());
Probably a better (proper?) way to do this.
