manipulate virtual directories or web applications from a java program

How to manipulate - add, delete, update or explore - virtual directories and/or web applications from a java application or servlet?

There are a quite of Java Classes for purposes such as these. Try asking a particular question like, "How do I create a file?". As an example the following creates a new file and then deletes it:

String filename = "C:\newfile.txt";
File f = new File(filename);
try {
  /* Create File */
  if (f.createNewFile()) {
    System.out.println("File sucessfully created");
  }
  else {
    System.out.println("File already exists");
  }
  /* Delete File */
  if (f.delete()) {
    System.out.println("File sucessfully deleted");
  }
  else {
    System.out.println("File not deleted");
  }
}
catch (IOException ioe) {
  ioe.printStackTrace();
}

thank for your response but this question i wanted to ask is not about files and directories of a file system but virtual directories of a web server.

You can translate a virtual path into a "real" path using

String ServletContext.getRealPath(String path)

. Things such as creating and deleting files cannot take place on virtual paths without the "real" translation being done first. Wushutwist
