Modify existing dataset at runtime

fruitining

Hi there,

I'm relatively new to BIRT and its API so this question might be a very rookie one. Still I could not figure out how to modify an existing dataset which is defined in my report desgin file. Its populated with data from a xml-file and I would like to read and write to the dataset within the API. Im not quite sure in which phase of the report processing this manipulation has to happen, but its obviously after the engine has retrieven the data from the xml-file.
I also would like to build a dataset from scratch with values I retrieve directly from my java application.

Could you give me a hint which classes and methods are relevant to do this.

Any help would be appreciated.

Sounds like you need a scripted data source.
