Hello All,
I have recently read one of the Performance improvement powerpoint and as per that we can use the JAXB for BIRT to improve the performance 10 times.
But I new to JAXB, I have never worked with it, also searched alot but did not found any information on JAXB with BIRT. if you have experience in working with JAXB and BIRT then please suggest me some links or help me by shareing some steps or sample code.
Thanks in advance for the help

That ppt was done on an earlier version of BIRT and since then the xml
datasource is much faster. That said you still may get some performance
boost using JAXB. I do not have an example of using JAXB but I do have
an example that uses a document builder. It is attached.

Hi Jason,
Thanks you so much for the response as always!!
I checked the example which you have attached. I tried to do few things so that I could use the JAXB with the BIRT report.
I did initial step, where I converted the rptdesign's file content to XSD and using jaxb compiler, created the Javaobject and able do marshaling.
But during this process I got few questions:
1. If I create an XSD, Javaobject and by writing some javacode I bind the XML data file and generate a report. then in that case how I will be utilizing BIRT? Because if I do these steps then i will be writing my own complete code and wondering how BIRT's existing features I will utilize.
2. Other possiblity is that, I might be taking wrong path, may be I need to do it some other way but as I have read about JAXB it is basically XML to Javaobjects and vice-versa. So I am thinking what is the best way to use the JAXB with BIRT to improve the performance.
Thanks a for the help

If you use JAXB you will need to use a scripted data source to access
the generated Java Objects much like the example I posted earlier uses
the Document Builder classes.

Thank you Jason.
I think then my approach will be good. I am creating my own Datasource and dataset using java and get final XML from JAXB.
But I think that will be little different from the example which you have attached as that sample by default has the XML but here I need to build one and then pass it.
Thanks

If you create an example that can be shared I would like to see if.

Thank you so much Jason for help!!
For the benefit of others, I would like to mention that I was able to use the JAXB with Open source BIRT, but I faced some issues with the Scripted Datasource and to solve that issue Jason helped me. But still that problem is not solved completely and I have raised a bug in bugzilla BUG-FOr JAXB.
Other than that you can refer the similar post reply which I raised on birt actuate forum BIRT with JAXB.
Thanks
Shivani
