if so how can i code in my application to open the pdf from another application
You can export your PDF to other application via the UIDocumentInteractionController.
Otherwise as #Björn Kaiser said, each application's storage is jailed and cannot be accessed by other application.
No other App can access your App's directories.

browse file in iphone I'm developing an iPhone app in which I have to upload the PDF and text files on server from iPhone. Please guide me can i browse all pdf files stored in iPhone into my application?
Its not possible to Monitor(Browse) the Files in IOS. Apple does not Approve this type of applications. And also iPhone/iPad we can't access the Other Application Data's. As per your point The PDF must be located in Other iOS Application. We can't Browse the Files Except Bundles and Documents folder.
Only way you can Upload file to Server and Make browser list Using Tableview.
The following are the possible ways to do this.
FTP UPLOAD:

I wanted to open the files available in my web application to its corresponding native apps in PC. I have created the set of program to download the file from web app but didn't know how to set that files to open with native app in system. kindly help me in this. If you have any other options to use rather than downloading and displaying the file please suggest me.
Note: I am using eclipse to develop web app
This problem is not related to GWT. Just provide links to files in your app. When a user clicks on link, user's browser/PC will decide what to do with a file. It will either open the file within a browser (PDF, images, some video and music files depending on a browser), or it will offer to save them.
In the web page, I have file upload widget. I need to show this web page on UIWebView. Is it possible to browse the file system and upload the pdf, doc, xls files?
Note: this answer was correct when written in 2012 and iOS 5 was current. iOS 6 introduced media uploads and iOS 8 allowed arbitrary file uploads.
No is the short answer. iOS has no user accessible file-system.
At WWDC they announced the ability to upload pictures in iOS6 but there is no publically available information on how that works.
You could do it by interacting directly with the website using the lower level tools (NSURLConnection, etc) and creating your own "open" dialog.
iOS grants the webView no means to browse the file system, so no you will not be able to use the normal upload mechanism in UIWebView
You will have to present some API to your web server that allows you to send images as POST
The answer would be NO, since the webview runs in a different sandbox as compared to native applications.
Also there is no accessible file system mechanism like android for iOS.
Even native application have very limited file access pertaining to only their own and certain user directories like tmp, documents etc.
I am writing an app that will be downloading user's documents from a remote source. once my app has this document I want to open it in the default application. (.PDF) In android it was simple, but I cant seem to find any resources for iPhone.
How do I open the default application with the file?
EDIT
The file on the remote source is not a url. it needs to be downloaded through a web-service. I will either be saving the file to disk or trying to open it from memory.
You are probably looking for UIDocumentInteractionController. Read this guide as well for more information.
Can I download a PDF file and shows it without use UIWebView?
I need to show PDF and get full control of its show...
Also, Can I download and strore PDF into filesystem app?
Thx
You can download a PDF the same way as you would download any other file, using an NSURLConnection or NSData's +dataWithContentsOfURL: method. This file will be stored within your application's sandboxed documents directory. Other applications on the filesystem will not have access to it.
As far as viewing the PDF without using UIWebView, this can be accomplished using CGPDFDocument, as described in the answers to this question.
