I want to test in jsp if user does need to log in, e.g. if user has already logged in and by back button is calling login.jsp for second time. My login.jsp has code : <logic:empty name="<%= IAppConstants.USER_CONTAINER_KEY%>" scope="session"> <html:form action="/login"> .... </html:form> </logic:empty> <logic:notEmpty name="<%= IAppConstants.USER_CONTAINER_KEY%>" scope="session"> <logic:notEqual name="<%= IAppConstants.USER_CONTAINER_KEY%>" property="userViewR" value="false" scope="session"> You are already logged in! </logic:notEqual> </logic:notEmpty> So i test for that bean named UserContainer in session scope, where it resides when login completes. Unfortunatly, if user not logged - it throws "[ServletException in:/login.jsp] Cannot find bean UserContainer in scope session'" Reading api docu, I thought logic:empty would test bean for null(existing or not existing)? Can any of you help me ? --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] ______________________________________________ Disclaimer and confidentiality note Everything in this e-mail and any attachments relating to the official business of Standard Bank Group Limited is proprietary to the company.
