Hi,

I'm using birt 2.5.0 (everything worked fine when we were running 2.3), java 1.6 and tomcat to create a simple report that contains a chart in it. The report works perfectly when application is hosted on Windows but the image in the chart would not show up when the report is hosted on linux (FC4). I look in the temp image directory and the image file (.svg) is there under the default /report/images/sessionId/subSessionId folder. No error in the log even when it is set to finest. Any idea?

Thanks

What browser are you using to view it? Can you change the type to png,
to check and see if it is an SVG viewer error?

I use Firefox 3.5.7 and IE 8 and tried all different output format types including png. The .svg file loads fine on its own. Very bizarre.

Take a look at the following links:

http://wiki.eclipse.org/BIRT/FAQ/Charts2.2#Charts_not_render ing_on_Unix_systems

http://www.birt-exchange.org/forum/eclipse-birt-newsgroup-mi rror/11888-report-viewer-error.html
http://www.birt-exchange.org/forum/designing-birt-reports/11 221-charts-failing-web-viewer.html
http://www.birt-exchange.org/forum/eclipse-birt-newsgroup-mi rror/11247-birt-chartting-errors.html

A couple other things to look at:

1 - what is the image src value in the generated html. Note that if you
are using the viewer you will need to use the /preview mapping instead
of the /frameset mapping to get the img src.

2 - set the logging in the web.xml to FINE and post the log results.

Run it again and get the new image src. Try to enter the url and see it
the image is displayed. ei
http://localhost:8080/WebViewer/preview?__sessionId=20100210 _171252_006&__imageid=custo
m954a64126ba1c68434.svg

I wonder if this is a permission issue.

I tried that and nothing showed either, body with empty <pre> tag. It looks like the code goes into some strange block of code that does nothing under some weird condition. It would be too much trouble for me to set up a linux development environment to debug this Sad

ok, I stepped through the birt servlets and here are the findings. The reason the image is not showing is the servlet is not invoked at all. Any idea why?

this request invokes the BirtEngineServlet properly--> http://localhost/preview?__report=test.rptdesign&__bread crumbTrail=testchart.rptdesign

this does not go through BirtEngineServlet for some reason, and this is the real cause for the image not showing --> http://localhost/preview?__sessionId=20100211_160524_446& ;__imageid=custom62c27b126bee04d3511.png

Can you open a bugzilla for this? Maybe someone on the team has seen
this one before.

Thanks Jason for all you help. I found the problem. It was our filtering code that prevented the servlet from being called Mad .
