I would suggest using something like
<jsp:useBean id="beanId" scope="session" class="BeanClass" />
<jsp:setProperty name="beanId" property="name" value="New Name" />
instead. This will work.
The reason that what you do doesn't work is that you are not changing the
properties of the bean instance in the session scope; you only change it in
an instance local to the page. If you absolutely want to create a new instance
to replace the current version in the session scope using a scriptlet, use:
<%
BeanClass newBean = new BeanClass();
newBean.setName("New Name");
session.setAttribute("beanId", newBean);
%>
