OAF Integration with XML Report (Merge Multiple VO's)
In this sample, you will get to know how to merge multiple VO's into single XMLDocument and pass this input to RTF Template using : TemplateHelpder API to get the desired output.
RTF Template
Make sure you get the xdo files from $JAVA_TOP and move them in your myclasses of Jdeveloper
Below is the logic of the controller for the buttons in the page :
