Strins filePath=getServletConfig.getServletContext.getRealPath("/someFolder");

String fileName=File.seperator+"test.txt";

File file=new File(filePath+fileName);
if (file.createNewFile()) {  
	System.out.println("file created");
	}  
	else {  
		System.out.println("failed to create file");
	}  

This should create a file in my workspace,in somefolder under webcontent.but not working.

any other approach will appreciable.

Thanks !!

I belive this does not works because "somefolder" does not exists or test.txt exists already.
Have a try:

        String filePath=getServletConfig.getServletContext.getRealPath("/someFolder");   
        File file = new File(filePath, "test.txt");   
        if (!file.getParentFile().exists()) {
            System.out.println(String.format("Creating folder %s...", file.getParentFile().getAbsolutePath()));
            if (file.getParentFile().mkdirs())
                System.out.println("Done");
            else
                System.out.println("Unable to create folder");
        }
        
        if (!file.exists()) {
            System.out.println(String.format("Creating file %s...", file.getAbsolutePath()));
            if (file.createNewFile())
                System.out.println("Done");
            else
                System.out.println("Unable to create file");
        }
        else
            System.out.println(String.format("File %s already exists!", file.getAbsolutePath()));

That is a great help....and it says file already exists..but i can't find it in the folder. where it has been created already ?
Thanks

You are seeing full path to the file in that output message.
If you're not seeing such file in you'r file explorer, perhaps it's hidden or somehow invisible to the user. Copy full path of that file, run notepad or other you'r text editor and click open -> paste copied path -> return key press.

Absolutely , you are correct !! i did that thing and an notepad turns into a .txt file ,it show the name of file. but why it is happening like

that..what do i need to do if i want to create a file on my workspace, e.g like relative to web-inf or anywhere in workspace.


Please Suggest.
