Help with Struts-Logic Tag
Hello Guys,
I have this tag ...
<logic:notPresent name="hello.world" ><logic:redirect
href="routes-login.rr" /></logic:notPresent>
And I need to change hello.world to Konstants.HELLO_WORLD. Now this...
<logic:notPresent name="Konstants.SESSION_USER_KEY" ><logic:redirect
href="routes-login.rr" /></logic:notPresent>
does not seem to work( of course ).
Please help. Thanks
Richard

Sorry slight typo - try something of the form:
<logic:present name="<%=Konstants.SESSION_USER_KEY%>">
<logic:redirect href="routes-login.rr" />
</logic:present>
Note the <%= at the start of the name value.
If you look using Google you can problem find a simple tutorial to
explain all about the logic tags but put simply the above statement
checks for the presence of a bean named the value of
Konstants.SESSION_USER_KEY. If this bean is present then it will
evaluate the nested content of the tag.
In most tutorials (I'd imagine) you'll see the value of the name
attribute will be something like "user". By using
<%=Konstants.SESSION_USER_KEY%> instead you're telling it to look up
this value.
Hope that helps you a bit.

Try using:
<logic:notPresent name="user" >
<logic:redirect href="routes-login.rr" />
</logic:notPresent>
Where user = Konstants.SESSION_USER_KEY, or maybe even:
<logic:notPresent name="<% Konstants.SESSION_USER_KEY %>" >
<logic:redirect href="routes-login.rr" />
</logic:notPresent>
