so give me guidelines to do this.
Thanks and regards,

You can show the PDF file in a "iframe" and by opening a new window. The "source" of the iframe should the path of the "PDF" file.
If you are using "window.open" then a new window will popup. There is no way you can open the file in a Tab dynamically.
