jstl el in <sec:authorize access

[reperion]

hello!
i'm new in security and not familiar english.

so, i use jstl el in security tag.
<sec:authorize , access attribute

my code

<sec:authorize access="hasRole('ROLE_ADMIN') or ( '${simpleBbs.username}' == principal.username )">

just compare principal.username with simpleBbs.username

that code makes this error

/WEB-INF/views/bbs/bbsForm.jsp(63,3) According to TLD or attribute
directive in tag file, attribute access does not accept any
expressions

althougth i can use ${ } in jsp and <c:out value="${}" />

i don't know why that's not working.

i use tomcat 6.0 and sevlet 2.5

please help me
have a nice day~ guys~

The new tag attributes don't support EL. I think this would be handy, and (other than the obvious potential confusion between JSP EL and SpEL) think it's probably worth asking Luke or filing an enhancement JIRA.
