using JSP to read a file from the local file system

I need to read a file from the local file system using JSP, save it as a string , and send it to a 开发者_如何学编程webservice(deployed using glassfish) for processing. Can anyone suggest how to perform File IO using JSP?

Thanks, Deepak.

Doing File I/O from a JSP is the same as doing it normally: Just use the java.io or java.nio classes. If you need to map a virtual path to a real one, you can use ServletContext#getRealPath.

Technically, I tend to agree with T.J. here. But actually its not the same, its a bad idea altogether.

If you want to upload a file to the server and process it, then use a html form with fileupload field and select the text file and submit the form . the file will be uploaded to the server where you can process it
