View/archieve combined reports

skv

Hi,

I have bunch of intermediate birt reports (documents). I want to render them in to a single doc/ppt/html/pdf document for archive and email.

Does Birt provide any way to render multiple reports in to one single document (html/pdf/ppt/doc)?

Is frame? servlet capable of rendering multiple design doc at a time?

I am having tough time combining PPT and doc reports, specially.

Currently BIRT does not handle this. You could do it with html or pdf pretty easily if you are using the RE API though. Attached is an example that uses the iText library that is already included in BIRT to combine two pdfs reports.

package REAPI;
