Check whether user is Logged In to Application (Appfuse Project)

How can I check whether a certain user is already signed into my application? I want to do this so I can redirect someone that tries to login using the same username to logout.

FYI: I use appfuse project generator.

Solution

  • In a JSP, you can use the following to see if they're logged in:

    <c:if test="${empty pageContext.request.remoteUser}">
    not logged in
</c:if>
<c:if test="${not empty pageContext.request.remoteUser}">
    logged in
</c:if>
