Betreff: Re: <util:counter scope=3D"session"/>


Corey,

thank you, it works fine, but I was not know that was =
create-session=3D"true"
exist.

Where I can find doc about all built-in taglibs and about their =
attributes?

Or better, do you know where I can search about it?

Very thanks?

Pier Paolo.

hi,

Have you setup a session using create-session=3Dtrue or
request.getSession(true)?
for example

1)
<xsp:page
 language=3D"java" create-session=3D"true"
 xmlns:session=3D"http://www.apache.org/1999/XSP/Session"
 xmlns:xsp=3D"http://www.apache.org/1999/XSP/Core"
>

<Your stuff/>

</xsp:page>

Corey
