To preview the results of the defined query click the Preview Results item. To do that you should bring up the New Data Set wizard. Using the plug-in and manifest Extensible Markup Language XML files, the plug-in registers itself as an observer with the data engine. The task requires the name of a report document and the name of a table with a data set binding.

Likewise, the DataSetWizardPage is the first page that is dreate in data set creation. Next add a new BIRT report. In the Data Set Name section specify the name.
Let’s it be HbDataSet. View image at full size. Several different extension points are defined in BIRT.
The factories must generate observers for data source connections, data set queries, parameters, and result sets see Figure 1.

I was able to get it to work by adding it to the viewer plugins’s scriptlib directory: The complete source for the plug-in is available in Download.
A dynamic list of name-value structures ExtendedProperty structures that specify private run-time data or attributes specific to the ODA connection. Again, to preview the results switch to the Preview Results item.
