Separate DataSource and DataSet

chrisdutz

Hi,

I am currently developing a Birt ODA driver to access services. For this I have created A specific datasource (In my case for talking to a BlazeDS service) and a very generic DataSet that does the query evaluation. https://dev.c-ware.de/confluence/display/PUBLIC/Amf-Datasource+for+Birt

My Idea now is to create a Spring Datasource that allows me to switch the DataSource in the report from the BlazeDS to the Spring Datasource and access the services directly without any marshalling and unmarshalling.

Unfortunately it seems the DataSet is directly couppled with the DataSource (At least if I use the template in Eclipse that generates the stub for a custom DataSource and DataSet).

So is there a way do decouple the DataSource and the DataSet and use one DataSet with multiple DataSources (optionally even as a Standallone version withouth any DataSource ... as this one would work on input provided by data-binding).

Chris,

I do not think you can decouple. You can create different dataset types for one data source (ie jdbc query or stored proc) but they are tied to one data source. Not sure if this will be helpful, but Josh from the Spring Project and I put together a article on BIRT and Spring http://www.springsource.org/BusinessIntelligenceWithSpringAndBIRT

Using this approach you could call Spring objects without a dataset at all.
