zero byte reply from chartServlet @ /preview

Hi,

I'm trying to deploy the birt 2.3 viewer application on Solaris. My problem is, that the charts are not shown in the browser.

I have checked the servers filesystem, and I can see the images being generated.
I can also run an export to PDF and the images will be in the report.

In the HTML I find the following reference to the image with the following src:

/birt-viewer/preview?___imageid=custom1235abcde.png

I checked and double checked that custom12345abcde.png is in the filesystem. I have copied the file over to my workstation to confirm that it actually is a png - and the contents are also the expected graph.

As stated in the subject, when I request the beforementioned image src directly, I get a zero byte reply. (Browser just shows nothing, wget just shows HTTP-200 and a zero byte file).

I have set up the logging to finest, giving me a lot. No Errors, no warnings, nothing. Also, nothing at all is written when i request the image... I feels like it's just.... dead? ;-)

Seems to me, like something is going terribly wrong in the Servlet that as mapped to /preview, or my setup is somewhat incompatible. But without any logging or error at all, I don't know where to look. I already tried setting the BIRT_VIEWER_IMAGE_DIR, but that also did not change a thing.

So, to sum things up:
Chart generation works
PNGs are in the filesystem
therefore PDF export works as well
/preview Part of Viewer does not react at all

Where do I go from here? Any advise, please?

bye, Michael

It's a problem in the viewer. It depends on session cookies. I have filed an enhacement request in the bugtracker, so that at least some kind of error is given to the user. <br />
