to pass values between jsp

[rosaria italia]

Hello, How can I pass hidden's value from a jsp page to other?
My code is:
a.jsp
...
<h:form id="insUser">
...
<h:inputHidden id="flag" value="1"></h:inputHidden>
...
</h:form>

b.jsp
<%String flag="";
flag=request.getParameter("flag");
out.print("flag="+flag);
%>

b.jsp shows: flag=null

Could you help me?
