Hi All,
Is this issue is invalid? I have seen similar error posts on sakai forum
also.
Please at least can anybody provide me guidance to resolve this problem. I
am trying to find out root cause behind this error , but still no luck. It
's not even calling any announcement related methods. Then how it is
generating (rendering )announcement sections for other users ?
I am currently debugging sakai-portal-render-impl,
sakai-portal-render-engine-impl. And when this error comes , its not
showing even showing any errors in logs.
Anybody can tell me atleast what can be the possible reason behind this
error ?
It's been a week I am expecting a positive response.
Thanks

Hi Sakai ,
Can anyone help me to solve this issue ?
Is this error belongs to only 2.9.1 src ?
I have tried to used 2.9.x all version for source code portal-render. But
still that error comes . Is somebody is getting same error for student in
announcement ?
Thanks,

Hi ,
I have tried with debugging functionality for site page rendering ,I am able
to see session in debugger mode also .
Session s = SessionManager.getCurrentSession();
Value for session is available .
So how error can come with saying no session established .
And if tool session is not established then how can user will be able to see
other tools like gradebook,attendance,profile,subjects.....
As my student user is able to see all these tools, so tool session is
established .
But one more thing I have noticed is : in includePageBody.vm file value for
: ${tool.toolRenderResult.getContent()} is nothing but whole error
"session established no tool session established error .
<!-- end Tool Col2 -->
<!-- start Tool Body -->
#if (${tool.hasRenderResult})
<div class="portletMainWrap">
${tool.toolRenderResult.getContent()}
</div>
#else
<div class="portletMainWrap">
<iframe name="${tool.toolPlacementIDJS}"
id="${tool.toolPlacementIDJS}" title="${tool.toolTitle}"
class ="portletMainIframe"
height="475"
width="100%"
frameborder="0"
marginwidth="0"
marginheight="0"
scrolling="auto"
src="${tool.toolUrl}?panel=Main">
</iframe>
</div>
#end
<!-- end Tool Body -->
Above code generates contents for announcement for users.
Please guide me to solve this error , I am really stucked with this.
Thanks,

"no session established no tool session established error "
Hi Sakai Team,
I am using sakai source code 2.9.1 .
I am getting an error for user Student when he tries to see his site
homepage -error comes for announcement frame only as "no session established
no tool session established error".
I will try to explain what I have done till so far.
I have created a site , created site-Admin, then by using siteadmin, created
users like teacher,student etc.
So after that when I tried to login with different users, it only gives
error 'no session established no tool session established' for student user
only in announcement section.
It displays correct announcement when student user comes in My workspace. So
it means this error comes only when it comes to site.
I tried to debug source code provided at
<https://source.sakaiproject.org/svn/sakai/tags/>
https://source.sakaiproject.org/svn/sakai/tags/ for announcement , I have
tried to add logs to all methods in class "AnnouncementAction " as this is
the file where all announcement related actions goes on like
create/edit/update ,display announcement.
I am able to get all added logs for other users, but unable to get not even
single log for student user "when student user tries to see announcement in
site."
After some more research I found that this site or by default home page for
user gets rendered from portal-render(part of portal), where I got to know
this error gets loaded from error.vm page.
Why this session error comes for only user student and in site only ?As
announcement gets rendered successfully in by default Myworkspace tab.
Can anybody guide me how I can resolve this error so that student will be
able to see his site's announcement similar to other users(admin,teacher
etc).
I also tried to truncate date for the tables related to announcement which
I knew so far i.e announcement_channel & announcement_message
I have also seen similar posts are available on sakai forums , but nobody
has given solution for it.
Please guide me in this context.
Thanks,
