1. Use the registry class to determine what file is used to open a .pdf file.
HKEY_CURRENT_US ER\Software\Mic rosoft\Windows\ CurrentVersion\ Explorer\FileEx ts\.pdf\OpenWit hList
HKEY_CURRENT_US ER\Software\Mic rosoft\Windows\ CurrentVersion\ Explorer\FileEx ts\.pdf\OpenWit hProgids

You could then handle the case where the user does not have .pdf reader installed, by directing them to FoxIt's website, or some other .pdf reader site.

2.You could pass the name of the exe file in as a String variable. eg get it from your String[] args.

How to open the existing PDF file using iText

Open up regedit and go to those registry entries. They should show what program you use to open .pdf files by default.

Once you get the program command line, you can simply send that to the Process to exec.

Runtime.getRunt ime().exec("run dll32 url.dll,FilePro tocolHandler C:/pdf/test.pdf");


Do any one faced this issue? Please help me out.

You're using url.dll to open a non-url.

[gaya3]

can you please suggest some solution for opening non-url?

Registry method: There won't be a standard answer for all types, unless you use the registry method. Even then you still have the problem of 'What if there is no designated program to open files of this type?'

If you know for sure what type of files you will be dealing with, you may be able to find a particular dll that works with it.

You could also probably go
r.exec("C:/pdf/test.pdf");
and let your computer deal with it.
