glassfish - How can I get j_username on my index.jsp after successful authentication with j_security_check? -


i'm using j_security_check on login.jsp. server glassfish server 3. works, when user authenticated opens index.jsp. problem need j_username in index.jsp, couldn't find way of doing it. solutions found in java , need works jsp.

any ideas? thank in advance!

the involved request in jsp el available pagecontext#getrequest(). logged-in user available httpservletrequest#getuserprincipal(). username in turn available principal#getname().

so,

<p>welcome, <c:out value="${pagecontext.request.userprincipal.name}" /></p>

should do.

using <c:out> way not necessary, useful case username contain special html characters malform html output <, >, " , on (which source xss attacks). <c:out> escapes them displayed literally instead of being interpreted part of html markup.
