question about WebdavResource.exists()

[Yong Hu <hu...@yahoo.com.cn>]

All,
 
Does anyone know how to use exists() method in org.apache.webdav.lib.WebdavResource?
 
 
In WebdavResource.java's comments, I find that exists() is similar to the exists() in java.io.File, so I think if i want to check if one file(such as files/test.txt) exists, i can do as following:
 
  1. create a instance of WebdavResource;
  2. call setPath(/rootpath/files/test.txt); (rootPath is the slide's root path)
  3. call exists() to check if the files exists.
 
but if the file doesn't exists, HttpException will be thrown when calling setPath(), so I have no change to call exists(). 
 
Is my usage of exists() right? If not, how should i use it?
 
Thanks in advance.
 
regards
Yong

[Ingo Brunberg <ib...@fiz-chemie.de>]

I would recommend not to use exists() at all. Whenever I want to check
the existence of a resource I simply use the HEAD method.

For the given example:

if (webdavResource.headMethod("/rootpath/files/test.txt") {
   // test.txt exists
}

Ingo
