BIRT on Tomcat - caching [message #134799]

Running a BIRT report under Tomcat, it creates a file called
reportname.rpddocument

Then next time you call up the report - even with different parameters -
you get the cached version. Why is this - and how can I make it make a new
report each time?

This even happens with the sample report supplied with BIRT.

I am running a very recent version (runtime 2.0.1) - and I don't recall
this as a problem from earlier, but I'm not certain.

thanks
Simon

Hello Simon,

try to add __overwrite=true to your URL.

so your URL should look something like this:

http://birtserver:8080/birt-viewer/frameset?__report=yourrep ort.rptdesign&__overwrite=true

this worked for me!

hope that helps!

Even that seems to fail sometimes. Looks like the browser caches the
report too, so adding a random (or time based) dummy parameter to the
url helps in that.

It is also possible to add __document=name parameter, and using
something special in it. I use "rptcache/<sessionid>.rptdocument ( I
have created a rptcache directory and using one file per servlet session
so that the users do not overwrite each others reports).

This newgroup is wonderful.
