Extracting report parameters from a design file

Hi all,

This has probably been asked and answered before ...

I'm looking for a way to open a design file and extract the parameter information from within.

Is there an API in place to support this kind of thing?

Thanks!

Hi Dennis,

Can you explain a little more about what you're wanting to do?

Sure.

We have a centralized server that runs a service to execute reports (either scheduled or on-demand). We store the rptdesign files in a database that the service uses and when a report is requested the service uses the BIRT report engine to render the report and stream it back to the requestor.

Presently, we have a fairly simple schema to map user-facing report parameters. The UI uses this information to gather the parameter data from the user and sends it to the service...

I would like to get rid of that schema and have a means of looking inside the rptdesign file itself to determine what parameters are there and all of their attributes and present it back to the UI for presentation to the user.

Thanks,
-Dennis

Hi Dennis,

This is possible.. but you will have to code accordingly (making it very generic will be complex). Given a design file, you can access its parameters and attributes through APIs..

Thanks Abdel - good to know that it is possible ...

Can someone direct me to the API that I should be using for this?

Thanks again!
