Session variables using Struts tag in JSP
Can someone tell me how to retrieve session variable values using Struts
tags??
I tried <logi:match> but didn't work. All I am doing is checking for a flag
that I am setting in the session in my Action class like below..
Action Class:
session.setAttribute("loggedUser", "admin");
JSP:
<logic:equal name="registrationForm" property="accessLevel" value="1">
<logic:match name="loggedUser" value="admin">
<html:button property="Delete" onclick="callDelete();">
<bean:message key="button.delete" />
</html:button>
</logic:match>
</logic:equal>
and then trying to display my Delete button if the accesslevel is "1" and if
this flag is "admin". When I do this, I get an error saying
[10/20/04 9:53:18:165 EDT] 618b279f WebGroup E SRVE0026E: [Servlet
Error]-[Cannot find bean loggedUser in any scope]:
javax.servlet.jsp.JspException: Cannot find bean loggedUser in any scope
at org.apache.struts.taglib.TagUtils.lookup(TagUtils.java:1038)
at
org.apache.struts.taglib.logic.MatchTag.condition(MatchTag.java:179)
Can I use any other tag to describe both conditions in one tag or is the way
I am doing right?
TIA
Gnan

Based on the error message, it looks like you're using the tag
correctly, but the attribute isn't being set correctly. I can't see
anything wrong in the code that you've included. Forgive me for asking
this, but are you sure your Action class is being called?
