There are document hooks that you can use to insert things into the response of a page being written to the client.
Therefore, if you create a service which implements the IDocumentHookListener, you will then need to implement the
String doDocumentHook(int documentPosition, IPortalComponentRequest request, IPortalComponentResponse response)
and
void doDocumentHook(int documentPosition, IPortalComponentRequest request, IPortalComponentResponse response)
The first method, that returns a String, you can basically check where in the document you would like to write code, something like
switch (documentPosition) {
case IDocumentHookListener.HEAD_SECTION_BEGIN :
return "some string";
break;
case IDocumentHookListener.HEAD_SECTION_END :
return "some other string";
break;
}
The second method, simply writes out the String returned from the first method to the response, i.e.
response.write(doDocumentHook(documentPosition, request));
I hope this helps
