Java Data Source

Hi,

This is cross-posted from Deploying and Integrating...

I am evaluating BIRT against Jasper for inclusion in the component set to be used on our forthcoming project. We are committed to use JSF, Facelets and Trinidad components so we anticipate that we will need to build and alternative to the report viewer that works in our environment.

But my question is about how to access the data from the report:

Our Java framework provided mechanisms for retrieving the data from multiple sources - we will not be able to use the JDBC or Flat File data sources and I do not think that WebServices or XML data sources would be appropriate for various reasons. I think that I will have to use a Scripted Data Source to solve my requirements.

What I really want to be able to do is pass the data, as a Vector of Java objects for instance, to the ReportEngine in the IRunTask. Is this possible? I think not!

So I have settled, for now, for a Java event handler class as a ScriptedDataSetEventAdapter; I can write code to access my data set from there still using the framework. But I need to be able to pass parameters such as the keys or search criteria that the code will use to retrieve the data. Is there a way I can do this?

Thanks
Neil
