filesystems - WebDAV FileSystemProvider - Java NIO -


i have java application lots of nio methods files.copy, files.move, files.delete, filechannel...

what trying achieve: want access remote webdav server , modify data on server basic functions upload, delete or update remote webdav data - without changing every method on application. here comes idea:

i think webdav filesystem implementation trick. adding custom webdav filesystemprovider managing mentioned file operations on remote data. i've googled lot , apache vfs sardine implementation looks - seems apache vfs not compatible nio?

here's example code, imagine it:

public class webdavmanagertest {  private static defaultfilesystemmanager fsmanager;  private static webdavfileobject testfile1; private static webdavfileobject testfile2;  private static filesystem webdavfilesystem1; private  static filesystem webdavfilesystem2;  @before public static void initwebdavfilesystem(string webdavserverurl) throws filesystemexception, org.apache.commons.vfs2.filesystemexception {      try {            fsmanager = new defaultfilesystemmanager();            fsmanager.addprovider("webdav", new webdavfileprovider());            fsmanager.addprovider("file", new defaultlocalfileprovider());            fsmanager.init();         } catch (org.apache.commons.vfs2.filesystemexception e) {         throw new filesystemexception("exception initializing defaultfilesystemmanager: " + e.getmessage());         }      string exampleremotefile1 = "/foo/bar1.txt";     string exampleremotefile2 = "/foo/bar2.txt";      testfile1 = (webdavfileobject) fsmanager.resolvefile(webdavserverurl + exampleremotefile1);     webdavfilesystem1 = (filesystem) fsmanager.createfilesystem(testfile1);     path localpath1 = webdavfilesystem1.getpath(testfile1.tostring());      testfile2 = (webdavfileobject) fsmanager.resolvefile(webdavserverurl + exampleremotefile2);     webdavfilesystem2 = (filesystem) fsmanager.createfilesystem(testfile2);     path localpath2 = webdavfilesystem1.getpath(testfile1.tostring());      } }

after want work in application localpath1 + localpath2. e.g. files.copy(localpath1, newremotepath) copy file on webdav server new directory.

is right course of action? or there other libraries achieve that?

apache vfs uses it's own filesystem interface not nio one. have 3 options varying levels of effort.

  1. change code use existing webdav project uses it's own filesystem ie apache vfs.
  2. find existing project uses webdav , implements nio filesystem etc.
  3. implement nio filesystem interface yourself.

option 3 has been done may able customize else has written, have @ nio-fs-provider or nio-fs-webdav. i'm sure there others these 2 easy find using google.

implementing webdav nio filesystem scratch quite lot of work wouldn't recommend starting there, i'd take has done , make work me ie option 2.
