Hi Vidya,
You can create custom component with two views in one view you can have option for upload then in another view you can show the log in table view.
In first view .htm page for upload option you need to code
<thtmlb:areaFrame id="af1" >
<thtmlb:areaFrameHeader id = "af1"
title = "Upload XML Spreadsheat"
noPersonalizeButton = "TRUE" >
</thtmlb:areaFrameHeader>
<thtmlb:areaFrameBody>
<thtmlb:fileUpload id = "UPLOAD"
size = "40"
onUpload = "upload" />
</thtmlb:areaFrameBody>
</thtmlb:areaFrame>
Regards,
Deepika.
