Thank you, James
But even:
<c:out value="${USER.username}" default="username" />
<bean:write name="USER" property="username"/>
USER is a user session
<bean:write> can work,and prints myname
<c:out> can not work, and prints ${USER.username}
why ???
I seems like my JSTL does not work rightly.
tomcat 5.0 can support jsp2.0 and jstl 1.1
