Hi All
I want to validate the format of file path using struts.That is if the user gives c/:Test.txt instead of c:\Test.txt.PLz Help.
Thank you

Just use StringTokenizer and look for the /. If found replace it with the one you want.

There's nothing wrong with either path...
And what about other operating systems?

why would you allow the user to enter the path anyway?(not that it's a bad thing) Why can't you use a file browser?

You should always allow manual entry as well.
It works a LOT faster if the user knows what he wants to enter.

But I'd not validate paths at all. The client is solely responsible for that, all the server should do is gracefully handle the situation in which the file doesn't exist.

And NEVER let the user enter a path and/or filename existing on the server and have the server do something with that file. That's a massive breach of security.

Maybe I don't understand the context. Wouldn't it be better in many ways to have a browse button(say the user wants to upload something) even if he/she does know the URL?

yes, having a button as an optional way to fill the file location is fine.
But you should not require the use of that button by not providing an input field for manual entry.
Pressing a button, launching a popup, filling the location in that, clicking another button, that's 4 steps to fill the file location.
Just filling it directly is a single step, far faster.

Maybe not that important on a hobby site where people may use it once a month or so, but on a professional intranet application where it's used by many people many times a day it becomes first a major annoyance and then reason for the application to require changing to improve performance.

Also, one should never rely solely on clientside validation (which forcing the user to select an option from a popup dialog effectively is), as someone will come who circumvents that in some way.

Okay, that makes more sense. So basicly it comes down to the popups "blowing up" in the users face, which I've always tried to avoid. I guess you could have both validations as an option to suit both sides of things. Thanks for the help.

I'm a little confused here. Lets say this is an upload page were the user enters the path or clicks the browse button, whichever he/she prefers. How exactly do you get that file off their computer since there is so many restrictions with java?

HI
Thankz for your replies. Actually we r developing an Intranet application in which the user should specify the resource files and the result files folder which is in the server.So i need a validation to validate the entered file path is correct and available. Now i got another solution.tht is
/* to hold the file path */
StringBuffer localSBFilePath = new StringBuffer( File.separator);
/* to hold the boolean value for long term files folder exists */
boolean localIsLongTermFolderExists = false;
/* to hold the long term files folder */
String localLongTermFilesFolder = null;
/* to hold the FILE */
File localFile = null;
/* get the long term files folder */
localLongTermFilesFolder = PrimaryServerAdminPKForm.getPServerStorage();// Here PrimaryServerAdminPKForm is an form bean using Struts.
/* append the file path*/
localSBFilePath.append(localLongTermFilesFolder);
localFile = new File(localSBFilePath.toString());
/* check the folder exists in the given path */
localIsLongTermFolderExists = localFile.isDirectory();
/* if not throw exception */
if (!(localIsLongTermFolderExists))
{
throw new AppsCustomException("error.PrimaryServerAdminPKForm.primaryserver.FileNotFound");
}


Thankz for all
