Can iText notify a browser when the pdf is done loading?

I am streaming a dynamic iText pdf to a web browser.  Is there something I can put in the pdf that will notify the browser when the pdf is done downloading?  I know pdf's use javascript, but I'm not sure pdf javascript can communicate with browser javascript.  My browser needs to know when the pdf is done loading so it can perform other actions.

That's a function of the browser. I've never seen a "download" launch another process or notify the user. That would be a security risk.

Other than the EOF marker that the PDF should have, the answer is no. Your question is not an iText question, as it would be the same, regardless of the scripting language or library that is used on the server side to generate the PDF.

That said (written), you *could* put a page action on the last page of the PDF that you generate with iText, which action would launch a JavaScript on the PAGE_OPEN event of the last page. See Chapter 13 in the book for examples.

Please see the documentation for classes PdfAction/PdfWriter for the methods/events that are available to you.

Best regards,

I think it is possible because you can communicate from the browser to the PDf and vice-versa. However, it is not a good practice.

The only supported communication between the two is with Acrobat/Reader 7.0.5 and later on Windows with the IE browser.
