Are you getting the error on all reports?
What app server are you using?

Hi jason,

I am using Tomcat webserver. We have multiple reports on a same page which are displayed using IFrames.
This error comes only when a new Browser(Internet Explorer) is opened and reports are accessed. After that when tha page is refreshed or when we logout of the application and login this error doesnt come.

Are you using the tag libraries or just a standard iFrame? Can you post
an example jsp? What version of BIRT are you using?

Hi jason,

I am using BIRT 2.6. The reports are being loaded in a standard iframe. I am using APEX3.2 from Oracle. In one of the pages, I have added several iframes. Upon load of the page, I have called a javscript,

function foo()
{
var url='http://'+window.location.hostname+':80/birt-viewer/fram eset?__report=myreport.rptdesign';
var ifrm=document.getElementById('ifrm1');
ifrm.src=url;
}

In the viewer.properties files, I have
viewer.session.timeout=0

Kindly do let me know if you need any more inputs

regards

Sandy

Hi jason,

I am not using jsp. I am using oracle apex 3.2 , which is a rapid application development tool for building websites and this runs on Oracle database. With this it is possible to create pages quickly. In one such page, I have two combo box's and a button and they are used to filter the various reports displayed.When a user filters a report , all the filters are stored as that users preference so that the next time the user logins, he should be able to see the report filtered according to his preference.
Now coming back ot birt, the iframe is printed on screen using javascript..

<script type="text/javascript">
document.writeln('<iframe id=ifrm1 src=\'\' width=800 height=600 />');
likewise for remaing iframes
</script>

During onload I am calling the function below...

function foo()
{

/*here some statements are there to get users preference and store in a variable called as param. In case the user has not filtered reports so far, I am using some default values for report paramters/filter and then the statement below follows */

var url='http://'+window.location.hostname+':80/birt-viewer/fram eset?__report=myreport.rptdesign'+param; //here param is the report paramer i.e. users filter
var ifrm=document.getElementById('ifrm1');
ifrm.src=url;
....
like wise for all reports
.....
}

When tomcat starts, the reports are displayed onload without the error . After sometime, when a user logins, he can see that error, so he has to refresh the page in order for the report to load. There is nothing in stack trace.In the viewer.properties files, I have
viewer.session.timeout=0

Kindly do let me know if you need any more inputs

regards

Sandy

Sandy,

That property is for the viewer but Tomcat I believe defaults to a 30
minute session timeout. Do you think this may be the issue?
I think you can change this in the web.xml of
tomcat_home/conf/web.xml

<session-config>
<session-timeout>30</session-timeout>
</session-config>

I am still stuck here. For testing purpose, I have added a link with window.location.reload() and everytime the page gives the error , I click the link and the session expired error goes. But this is not the solution that I would like... Sad

Hi Jason,

For testing purpose, I made the timeout in web.xml as 2 min. Restarted tomcat and went to reports page, error came as usual. Then I refreshed the page and made all the reports to load. I then saw in the birt-viewer/documents folder that a copy of all reports that are currently being displayed exists w.r.t current session. I waited for 2 min and saw that they were deleted automatically. In my web application, I moved to a different page and came back to the report page. I saw the error as usual.

I believe that the report is trying to load from the previous session which has expired. If this is so, how do I make the report to behave as follows. If the session has expired, then it should create a new session and reload the reports.

I don't know if this observation has got anything to do with my current error produced or totally irrelevant. But it would be nice if I got the solution to the problem I am facing

Are you able to check the logs and figure out eactly where the exception gets generated.
If it's for the 'IViewingSession' then invoking birt-viewer from code could be the reason, not sure about that.
I got this exception when i was trying to use the RE APIs in the birt-viewer from java code.

Hope it helps.

Can you open a bug for this? As a work around could you try to add
&__overwrite=true ? This will recreate the report document every time
but may get around the problem.

There is nothing in the logs. Ofcourse needless to say in the web.xml of birt, the parameter for BIRT_VIEWER_LOG_LEVEL is WARNING currently. Should I change this?

Hi Jason
I have tried &__overwrite=true. I have also added the following in the web.xml of birt...

<!-- Overwrite report document each time. -->
<context-param>
<param-name>BIRT_OVERWRITE_DOCUMENT</param-name>
<param-value>true</param-value>
</context-param>

But it was futile. Next I added the "/run?.." tag instead of the "/frameset?...". Now I got "java.lang.IllegalStateException: The viewing session is not available or has expired." and something in the stack trace....

java.lang.IllegalStateException: The viewing session is not available or has expired.

Hi Jason,

My apologies in replying so late.

I did open a bug report. As you suggested, I changed the log level to FINE and there was still nothing in the logs. Sometimes, I find that a white image and a red cross mark at the left hand corner is displayed instead of the chart.

The bug is:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=329182

Xiaoying responded and is waiting on a response.

Not sure if it will help buy you may also want to look at using BIRT Tag
libraries.

Hi Jason,

I think I might have solved my problem currently. Just keepin my fingers crossed...

I am loading each of the report in the PREVIEW mode, i.e.
....../birt-viewer/preview?__report=.....

After that I am reloading each iframe twice. Sounds stupid, but's it seems to be working since a few weeks

We are also getting viewing session expired exceptions, I have included a log, looking at our log, initialization starts are 17:10 and 16 seconds, and we get the exception at 17:10 and 45 seconds, sounds like its very close to the default time out value of 30 seconds .


We are investigating and will update the case if we can resolve this.

the applicaiton page has an iframe, which has the report URL set its its source,

so we invoke the report via a URL, e.g./Viewer/report_name.rptdesign&parameters.


if you need anything else please advise

If you could post a HTML/JSP example that I can deploy to my tomcat
install to reproduce the issue it would be good.

I will be comming back to this shortly, we are only getting this error on some pages.

We have a large app, some pages all work fine, other pages result in 50 % of cases on the first login give a "view session has expired....".

The scenario is that we have two applications hosted in Websphere, the OLTP app in one context using the birt viewer in a seperate content with e.g Websphere, with the OOLAP running reports via a relative url e.g./Viewer......


I found these suggestions and I will try these steps first and then get back :
-------------------

http://pipecuts.wordpress.com/2011/01/13/birt-the-viewing-session-is-not-available-or-has-expired/

1 WebViewer.display()
from a Eclipse RCP View calling to display a BIRT report and your report is open without any problem within the view, I know how much you are happy with BIRT.

However, if when you click on Print Report toolbar command, and choose HTML print format, you see your report opens in a Internet Explorer window with a exception as follows, maybe you want to read the rest of this post.

This seems to be a Internet Explorer policy with iframe, cookies and cross-site.


Here you are the complete stack trace:

01 org.eclipse.birt.report.exception.ViewerException: The viewing session is not available or has expired.


The actual workaround is disable the Internet Explorer Protected Mode for your site zone or something like that. Mine was intranet zone, it was easy! These are the steps:

1.Open IE.
2.From the IE command bar, choose Tools and then Internet Options.
3.In the Internet Options window, click on the Security tab.
4.Below the Security level for this zone area (in my case, it's Intranet), and directly above the Custom level... and Default level buttons, uncheck the Enable Protected Mode checkbox.
Note: disabling Protected Mode requires a restart of IE, as you may have seen next to the checkbox in this step.
5.Click OK on the Internet Options window.
6.If you're prompted with a Warning! dialog box, advising that The current security settings will put your computer at risk, click the OK button.
7.Close IE and then open it up again.
As I was advised by Jason I filed the bug ID 333931. The initial discussion about this started in BIRT forum on this topic.

That's it!

Hello,

Today I encountered the same "The viewing session is not available or has expired." message again. Some months ago I managed to find a solution (see this post).

This time the issue was a bit different: it only happened when the reports were accessed from IE, but not from Firefox and only for some of them. Looking at the differences I saw that for some of the reports the URL included the hostname and for the others the IP address of the Tomcat server. The ones that were failing to be displayed were the ones accessed by IP.

So you could check how you are accessing the reports and how the URL is specified. In my case using the hostname of the machine hosting the Tomcat did the trick.

Regards,
Mudor

Can you open a bug for this? As a work around could you try to add
&__overwrite=true ? This will recreate the report document every time
but may get around the problem.
