how to insert loading icon in jspdynpage

Hello,

Portal version: CE7.3 EHP1 SP9

I have a requirement where I need to show a .GIF file as initial application loading icon before main jsp of the JSPDynpage DC opens.

I referred to following thread and achieved it in Web Dynpro DC but don't know how to achieve it in JSPDynpage type DC.

Loading... Please wait.

I saw many people (non-sap) achieve it by using scripting inside "head" tag in HTMLs. However, not sure how to adapt it for JSPDynpage type DCs.

Any ideas/suggestions/code-snippets?

Thanks & Regards,

Amey Mogare
