Hi

I need to create a directory under webapps/test/
which test is the application folder
http://localhost:8080/test/

I want to create http://localhost:8080/test/upload/abc/

The code does not create any folder.
private String uploadPath = "/upload/abc/", filepath;
filepath = request.getContextPath() + uploadPath;
File tempPathFile = new File(filepath);
if (!tempPathFile.exists()) {
tempPathFile.mkdirs();
}

Open in new window

Try to use
private String uploadPath = "upload/abc"; //no / at the end or the beginning
File tempPathFile = new File(request.getContextPath(), uploadPath); //leave Java to do the concatenations
this will at least make sure the folders are created ok.

Also - had you printed request.getContextPath() to make sure it is where it is supposed to be?

Other from this:
- See the log files for permission issues (you might not be able to create folders especially on a Unix if you do not have the permissions. (Put a try catch block - the method should throw an exception if this is the issue)

By the way...
private String uploadPath = "/upload/abc/", filepath;
is a bad practice and can lead to some strange issues if you need to change something... use
private String uploadPath = "/upload/abc/";
private String filepath;

still cannot create directory under tomcat webapps

i think it cannot do that, may have to use absolute local path

That's it I think. You need to pass the FULL path (that's why I asked for the request.getContextPath() -- if it is relative, you should get the real path.
In any way - I am always getting to real paths for any directory creations.

I think servlet cannot do it as I finally need to use the local full path
C:\\Tomcat 6.0\\webapps\\test\\upload\\abc

Neither request.getContextPath nor getServletContext().getRealPath did not work
