Creating an XML Report from OAF page

Question

Hi All,
I have a requirement to create a PDF report from an OAF page. From the below code , I was able to print the XML with the values.
I know i should map this XML to RTF by creating the Data defiition through XML publisher responsibility.
My understanding :
1. Generate the XML from Conttroller
2. Load the XML to RTF and map the fields
3. Register as Data Definition and RTF
4. Output seen
MY QUESTION IS : If i load the values from the below XML to the RTF and register in the data definition , i will get the same values every time it is right . From my understanding, if the data has to change in the report, ,there should be a way which will directly send the generated xml from the controller to the RTF (Without step2)
I DEFINITELY BELIEVE, THAT I AM MISSING SOME THING HERE . PLEASE HELP ME
public void processRequest(OAPageContext pageContext,
OAWebBean webBean) {
super.processRequest(pageContext, webBean);
OAApplicationModule am =
(OAApplicationModule)pageContext.getApplicationModule(webBean);
OAViewObject vo = (OAViewObject)am.findViewObject("colorVO1");
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
//(XMLNode)vo.writeXML(4,"")
try {
((XMLNode)vo.writeXML(4, XMLInterface.XML_OPT_ALL_ROWS)).print(outputStream);
} catch (IOException e) {
// TODO
throw new OAException("The value of VO is " + vo,
OAException.CONFIRMATION);
System.out.println(outputStream.toString());
Generated XML :
<colorVOEx3Row>
<UserName>abc</UserName>
<UserId>33102</UserId>
<CreatedBy>27241</CreatedBy>
<Clr1>0</Clr1>
</colorVOEx3Row>
<colorVOEx3Row>
<UserName>deg</UserName>
<UserId>33604</UserId>
<CreatedBy>1135</CreatedBy>
<Clr1>0</Clr1>
</colorVOEx3Row>
<colorVOEx3Row>
<UserName>****mno</UserName>
<UserId>33643</UserId>
<CreatedBy>24587</CreatedBy>
<Clr1>2</Clr1>
</colorVOEx3Row>
</colorVOEx3
Please let me know what should me my next steps to generate the report. if i load the XML above to the RTF , irresepscive of my data from teh page, i will always get the 3 rows.i..e..(abc,def,*** mno).
Hope i am clear.

Hi Anand,
Thanks for your reply. I have gone through the link you provided . It gave me excellent information. But just one clarification , when we create the data definition, dont we have to add any of the files like 'XML Schema','Data Template','Preview Data','Bursting Control File'.
The reason, i am asking this question is, when i proviously worked with XML reports in 11.10.2, we used to attach a .xml file to the Data Template of the data definition ,which would populate the RTF.
Now here, if i dont attach that file in the data definition, will the XML data direclty mapped from contrlloer ?. I assume ,The only thing i need to do is to MAP the XML tags to RTF before registering ..
Please let me know if i am missing some thing
Thanks
