Hi!
I'm facing a very strange issue while running the birt-viewer application in Tomcat 6/7 on Ubuntu 10.04 (AMD 64bit).
Rendering the very basic sample report (test.rptdesign) takes around 2 minutes, when I use the "frameset" URL:
/frameset?__report=test.rptdesign
It's very fast (< 1sec) rendering the same report with the "run" URL:
/frameset?__report=test.rptdesign
It seems, the problem is related to some component(s) in the frameset UI, but I don't see why. I tried Tomcat 6, Tomcat 7, several versions of the birt runtime,
different Java version (SUN, OpenJDK), but without any luck. It's always the same behaviour: the UI gets loaded up to a certain point, then it seems to hang. No
data is being transfered for up to 100 seconds and then suddenly the report appears. During this time, I can see no trace of activity (using top) on the Linux server.
I'm using birt since years and installed the birt-viewer in many different environments but never faced a similar issue. It's
driving me crazy!
Maybe someone here has some suggestion. Any ideas are welcome!
Oli

After you run it initially, if you run it again does it take a long
time? Can you check the web-inf/platform/configuration directory? After
running do you have files in this directory other than the config.ini?

The viewer AJAX code used in the /frameset mapping uses web services to
connect back to the server, but it should not be connecting outside.
