Task 4: Run the code
5 Create a Run configuration for GenerateDataObject.java class.
1 In Package Explorer, select:
GenerateDataObject.java
2 From the main menu, choose Run➛Run Configurations.
3 Double-click the Java Application link in the left frame of Run Configurations. The GenerateDataObjects configuration gets created.
4 Choose Run. Save and Launch appears. Choose OK.
6 After the execution completes, refresh the contents of the DataObjectExample project. test.rptdesign appears.
7 Open the report design and view the XML source. The XML contains a datamart element that points to include.datadesign and a data source called include, as shown in the following code:
<datamart-node location="file:/DataObjectExample/include.datadesign">
...
<data-sources>
<data-mart-data-source name="Data Source" id="4">
<property name="datamartURL">include</property>
<property name="accessType">transient</property>
</data-mart-data-source>
</data-sources>
8 In Data Explorer, expand Data Sources to view the new data source, as shown in
Figure 28‑6.

The final code for GenerateDataObject is shown in
Listing 28‑3.
