The viewing session is not available or has expired

Not sure if this will help but there is a setting to change the browser used:
Window->preferences->Report Design->Preview->Always use external browsers check box below it is a link to set the brower preference. You may also want to set the host and port the viewer starts on using the Preview->Preview Server entry.

Jason

JasonW, thank you for your reply! 
 
I delayed my answer because I bought a new notebook and I'm migrating my environment to Windows Seven x64. 
 
For now, I did tests in both environment Vista x32 and Seven x64 (but JVM and Eclipse are x32) with no success: IE is always opened and the message "The viewing session is not available or has expired" is displayed. 
 
My BIRT Report Designer standalone is running without problems, as I can see, in Seven x64. 
 
However, I can't find the BIRT perspective and views that is installed within Eclipse. They are all missing! :blink: 
 
I uninstalled BIRT features and installed them again into Eclipse with no success too. BIRT is installed within Eclipse, but disappeared. I started Eclipse with a -clean parameter with no result too. 
 
So, I have two problems: 
1. the original subject of this topic 
2. BIRT perspective and views within Eclipse missing in Seven x64. 
 
Any help is appreciate!

I have a update: 
 
If I change the following code from this: 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>WebViewer.display(fileUrlPath, browser, myparms);</pre>
 
to this: 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>WebViewer.display(fileUrlPath, myparms);</pre>
 
Of course, my view isn't opening. However, the report viewer is opening straight to the browser, not running IE, but running Firefox, the default external browser defined in Preferences as you suggested. 
 
Next, in the external browser on WebViewer toolbar, if I click on Print Report command, a new Firefox window is open with a report print version and the print dialog pops up. This way, all works! :huh: Not as I would like, however! 
 
 
Maybe this can be a clue! :unsure:

> Updated 
I do the following test: 
 
As the server defined in Preferences is localhost, I included it localhost in the IE trusted sites zone, or as local intranet site. Doing that, the IE is opening and the report is displayed with no exceptions. 
 
But only IE is the browser called yet, even if Firefox is the external browser defined in Preferences. 
 
This seems to be a IE policy with iframe, cookies and cross-site.

Instead of creating and uploading privacy policies to your sites, you can serve a ?compact policy,? i.e. a ?p3p? HTTP header, e.g.: ?IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT?. A policy generator can produce one instead of an XML file. </blockquote>

On issue 2 have you tried the all-in-one for 64?

On issue 1, you may have to log a bug. It may be just launching the default system browser.

Jason

I will do that and I will post the bug ID here for reference.

No. I just copied my environment from the old notebook to the new one. Then I installed the most recent Java SDK 32-bit and 64-bit version. However, my JAVA_HOME is defined to use the 32-bit version and Eclipse is 32-bit version too. 
 
I'm using BIRT RCP Report Designer to design my report and, in a other hand, just for minor fixes and tweaks, I use BIRT perspective from within Eclipse. This last one I installed from Helios Update Site. Both are 32-bit because I used it in my old Windows Vista notebook. Now this perspective was missing... 
 
 
-- 
And, what about the IE policy with iframe, cookies and cross-site? Is it possible to use that HTTP header, e.g.: "IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT"? 
 
TIA, JasonW! 
 
> Updated: 
 
My installation was using .link files in dropins folder for several dependencies. I discovered that GEF, EMF and others was not loading from there. They were working in Eclipse 3.6, but it seems not in 3.6.1; <a class='bbc_url' href='http://www.birt-exchange.org/org/forum/public/style_emoticons/'>http://www.birt-exchange.org/org/forum/public/style_emoticons/</a><#EMO_DIR#>/confused.gif 
 
So, I deleted all .link, remove BIRT installation, do a -clean running and reinstall BIRT again. Now, works fine!

Have you tried un checking the always use external browsers checkbox?
If you do this what happens when you click on the print?

Jason

I looked into this a bit more. You need to set an OpenWindowListener on your SWT Browser.

eg

browser.addOpenWindowListener( new OpenWindowListener( ) {

public void open( final WindowEvent event )
{
final Shell shell = new Shell( SWT.SHELL_TRIM | Window.getDefaultOrientation( ) );
shell.setLayout( new FillLayout( ) );
Browser browser = new Browser( shell, SWT.NONE );
event.browser = browser;
shell.open( );
}
} );

Jason

Jason, thank you for the new and valuable suggestion. 
 
Inserting your snippet, when click on Print Report, the IE is opening and then the Print Dialog pops up. This is what I was expecting. 
 
Without insert your snippet, the IE is opening and I need to use CTRL+P to get the Print Dialog. 
 
With or without check the always use external browsers checkbox, always IE is opened. <_< 
 
About the The viewing session is not available or has expired, after I disabled the IE Protected Mode for Intranet sites, the message is gone. 
 
To help others to setup IE for this setting, these are the steps: 
 
<blockquote class='ipsBlockquote' >
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.

A little question: 
-- Where come from the window variable in window.getDefaultOrientation()?

Hi Jason,

I have followed numerous posts about this same problem where you ask a whole lot of questions and I see very little solutions to this problem. We are three seconds from throwing it out.

We are running 2.6.2 of Birt in GWT and pointing an HTMLPane to our reports. When I use Framset i get the following error: The viewing session is not available or has expired.

We need to use the frameset as we require the exporting abilities provided in the toolbar.

Why is this happening?

I assume you are using the viewer plugin? If so did you do this?
browser.addOpenWindowListener( new OpenWindowListener( ) {

public void open( final WindowEvent event )
{
final Shell shell = new Shell( SWT.SHELL_TRIM | window.getDefaultOrientation( ) );
shell.setLayout( new FillLayout( ) );
Browser browser = new Browser( shell, SWT.NONE );
event.browser = browser;
shell.open( );
}
} );

Hi Jason 
 
I am sure Google Web Toolkit does not use Shell and Browser in that way so the below does not work for us. 
 
I have debugged and debugged and I have found one of two things, when my HTMLPane loads the url of my report it does not create a SessionID and I get a session timeout error. If I open the report in an additional browser at the same time of populating my HTMLPane it still gives me a session timeout but only the first time. Thereafter it is fine, but this only works if I open a new IE browser window. 
 
The second thing is that this only seems to happen on IE9, it works perfectly in IE 8. Could this be the problem. 
 
Please can you come back to me.

In IE 9 do you have cookies enabled?

Jason, 
 
Where exactly do you insert this? We are trying to render our reports (using the BIRT viewer) in an iFrame within another site and we get the session expired error message - which is why I've landed on this post in the forum. Any help is appreciated. A developer on my team was trying to get me to insert a P3P http header but I don't know where to put that either. Thoughts?

Meghan,

Did you get this solved? That solution had to do with using the viewer in plugin format, not the way you are using it. Do you have cookies enabled in your browser?

Jason

Jason, 
 
Unfortunately we still have not resolved this issue. We believe that IE is blocking cookies because our application and the embedded BIRT viewer are in different domains. We've been trying to insert a P3P header into various JSP pages (we've tried the Frameset Fragment page suggested here - <a class='bbc_url' href='http://www.birt-exchange.org/org/forum/index.php/topic/23881-setting-http-header-globally/page__pid__84768__st__0&#entry84768'>http://www.birt-exchange.org/org/forum/index.php/topic/23881-setting-http-header-globally/page__pid__84768__st__0&#entry84768</a> - but nothing seems to work. At this point we are completely stuck.

Meghan,

Can I get some more detail on how you are using BIRT? BTW have you tried using the tag libraries?
If you want, maybe you can show me in net meeting or placeware.

Jason

Jason, 
 
We have created reports within BIRT and are using the BIRT viewer within an Iframe in our application to display them - calling URLs like <a class='bbc_url' href='http://localhost:8080/reports/frameset?__report=report/NameofReport.rptdesign.'>http://localhost:8080/reports/frameset?__report=report/NameofReport.rptdesign.</a> No, I have not tried to use the tag libraries and am not very familiar with those. Does that help?

Maybe. I am not certain in your case, but it can be used cross context in the same server. May just want to give it a try:
http://www.eclipse.org/birt/phoenix/deploy/viewerUsageMain.php#tags
You can set the viewer tag to div or iframe output.

Jason

Jason, 
 
Sorry for the dealy - This reference doesn't really help me 'set the viewer tag'. Where/How do I do that? What happens if the two applications (our own application and the BIRT Viewer) on separate SERVERS?

Also, I'm not sure the taglib is going to work since our application is using strictly PHP. Sorry if I'm making no sense. My knowledge is mostly around report development and not web programming.

Meghan,

Create a jsp file with the following code:

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ taglib uri="/birt.tld" prefix="birt" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

</head>
<body>

<birt:viewer id="birttViewer"
reportDesign="master.rptdesign"
format="html"
scrolling="true"
height="700"
width="950"
isHostPage="false">
</birt:viewer>

</body>
</html>

Save the jsp file in your WebViewer root directory where the index.jsp page is at. Save it with a name like ViewerTag.jsp then in your iFrame put in the url like http://localhost:8080/reports/ViewerTag.jsp.

Make sure to change the reportDesign attribute.

Jason

Jason, 
 
I'll work on this but if I understand this correctly - we have to create a viewer.jsp page for every single report? Right now our iframe is referencing the appropriate report URL (depending on what the customer selected before).
