Sample report design with Java/javascript used in it

Migrateduser

<p>All,</p>
<p>      I am very much newbie in BIRT. I did some sample start up reports but not sure where to write a javascript or java code to customize the report. Does anyone have any sample where there are some scripting involved. It would be very much helpful.</p>
<p> </p>
<p>Thanks,</p>
<p> </p>
