Viewer session expired issue [message #716093]

Hey Jason

I have been intermittently getting an error / alert box during BIRT report loading saying "Viewer session has expired".

I am trying to render the BIRT report on the jsp file using the birt.tld. I use the birt:viewer tag here.

I have seen a lot of posts related to this topic but without any definitive solution.Could you please comment on this error? Please get back if you need any further assistance from me on the same.

Thanks much in anticipation.

Regards
Gaurav

Gaurav,

Is there anyway in your code to reproduce the issue where we could test
it? Can you post the code and version of birt you are using?

Hey Jason,

Thanks for the reply and apologies for not writing earlier.

This issue is very inconsistent but let me check if I could arrange for a sample code for your team to test.

Best Regards
Gaurav

Hey Jason

Its been long since I wrote on this issue. Unfortunately, this issue still haunts me. The only positive that has come up is I have been able to reproduce this issue, in a not very elegant fashion though.

What I noticed is that I get a "Viewing Session is not available or expired" every time I restart my tomcat server. This is the only consistent manner in which the error shows up.

I have a struts web application running on the apache-tomcat-6.0.18 server which interacts with the BIRT viewer(running on the same server in a different web app) via birt.tld using the frameset mapping.

Would this information help?

Thanks again.

Best Regards
Gaurav

Also after doing a View Source on the screen,I noticed that the report which fails has an incorrect(compared with the folder name in the document folder) value for the field "Constants.viewingSessionId" in the java.

Following is the code from Attributes.jsp of the birt viewer project.

<script type="text/javascript">
// <![CDATA[

Constants.nullValue = '<%= IBirtConstants.NULL_VALUE %>';

// Request attributes
if ( !Constants.request )
{
Constants.request = {};
}
Constants.request.format = '<%= ParameterAccessor.getFormat(request) %>';
Constants.request.rtl = <%= ParameterAccessor.isRtl( request ) %>;
Constants.request.isDesigner = <%= ParameterAccessor.isDesigner() %>;
Constants.request.servletPath = "<%= request.getAttribute( "ServletPath" ) %>".substr(1);
<% IViewingSession viewingSession = ViewingSessionUtil.getSession(request);
String subSessionId = null;
if ( viewingSession != null )
{
subSessionId = viewingSession.getId();
}%>
Constants.viewingSessionId = <%= subSessionId!=null?"\"" + subSessionId + "\"":"null" %>;
// ]]>
</script>

Can you open a bugzilla entry with steps to reproduce and post the bugid
here?

Any updates on the Bug 342625. The issue I am facing is similar.

Have you tried this with BIRT 3.7?

Not really, haven't tried 3.7.
