hi every one

i need the tab panel with curved panel heading edges.
so i try to set the curved edges image as a background to tab panel.

<style>
.activeClass
{
 font-weight: bold;
 background-image:url(/img/a-tab-selected.gif);

}
.inactiveClass
{
 background-image:url(/img/a-tab-unselected-flight.gif);
}
</style>
<rich:tabPanel activeTabClass="activeClass" headerClass="inactiveClass" >
....
</rich:tabPanel>

still i get the squared table panel heading as a result.
i don't know how to do this .
is there any help ..
