Getting file name from a directory path

[Raghu Nathan]

Hello everyone,
I need some help in determining the filename from a given directory path. After gettign that I have to save it in the DB with a different path. I dont need to physically save the file in the other path but just get the file name and prefix that with the other dir path.

Say, the file that I locate in my c:\ is in c:\MyDir\doc1.doc and I need to save it in the DB with the UNIX dir reference /unix/dir/.
So it should get saved as /unix/dir/doc1.doc in the database.

Now, I had used the following code to do that:
String dirPath = "/unix/dir/";

File filePath = new File(brBean.getRep_dir_path());
String fileName = filePath.getName();
String varFile = new String(dirPath + fileName);
details.setRepDirPath(varFile); //my data bean
System.out.println("Original Path:" + filePath);
System.out.println("Changed Path:" + varFile);

This seemed to work fine when I was doing in my development environment where everything was in Windows. When I do the same in the other environments, where the application runs on unix, I get a different result.

What happens with the above code is that it prefixes the UNIX dir path to the whole path identified. So the end result is: /unix/dir/c:\MyDir\doc1.doc

I was wondering if one way to fix this would be to use some string function(s) and get the file name somehow. So you'd have doc1.doc after eliminating the path in which it was identified. And then prefix the UNIX path to the file name.

Is that the most optimum solution?

I hope I have been articulate enough to explain my problem.

Also, I do not know if this is the right forum for this question. If its not, then excuse me and please direct me to the right forum.

Extracting the filename portion, given a full pathname, is very similar to another question in this forum... So... I am going to modify the solution from that thread...

Here is how you extract the file name portion, given the full name of the file...

   private static String extractFileName (String fullName) {
      Pattern p = Pattern.compile(".*?([^\\\\/]+)$");
      Matcher m = p.matcher(fullName);
 
      return (m.find()) ? m.group(1) : "";
   }

BTW, since I modified the code from another thread, I haven't tested it -- please test it first.

Raghu,

I am running into same issue. Have you figured out a fix for this?

Please share.

Thanks.

How about Henry's solution? It probably worked 3 years ago as Raghu Nathan hasn't replied afterwards stating it didn't.

That worked. But that is a workaround. I would like to know the fix for the original problem.

Thanks anyway.
