Re: [geclipse-dev] Null value for inputstream in gridftp 
Hi Romain,

I think thats just a bug and the only way to get the file is by browsing.
I think there are a few more bugs e.g. for me
URI uri = new URI("gsiftp://aliserv6.ct.infn.it:2811/dpm/ct.infn.it/home/geclipsetutor/testtest";); IFileStore fs = EFS.getStore( uri ); IFileStore homeDir = fileSystem.getStore(URI.create("/home/bw/wav/")); 
homeDir.copy(fs, EFS.NONE, null);
doesnt work . Have you tested this too and e.g. creation deletion of files?

cheers bernhard

Hi Bernhard,
in fact I don't want to browse the directory before downloading the file. My code should work in a general case for any kind of file server and some like http may not be browsable. 

If I try to open an input stream with a direct reference:
IFileStore fi = EFS.getStore(URI.create("gsiftp://grid009.to.infn.it:2811/flatfiles/SE00/biomed/tmp/simexplorer/application18.xml";)); 
       InputStream str = fi.openInputStream(EFS.NONE, null);
       if(str == null) System.out.println("null");

The result of this code is null.

Hi  Romain
This may help -> http://dev.eclipse.org/mhonarc/lists/geclipse-dev/msg01200.html 

I just tested to up and download a file and it was successful.
URI uri = new URI("gsiftp://aliserv6.ct.infn.it:2811/dpm/ct.infn.it/home/geclipsetutor/upanddown/";); IFileStore fs = EFS.getStore( uri ); IFileStore file1 = null; for (IFileStore store : fs.childStores(EFS.NONE,null)) { 
             if ( store.getName().equals("test.wav") ) {
               file1 = store;
               System.out.println(file1.getName() );
               break;
             }
           }
File a = new File("/home/bw/test.wav"); BufferedOutputStream ostream = new BufferedOutputStream(file1.openOutputStream(EFS.OVERWRITE, null)); BufferedInputStream istream = new BufferedInputStream(new FileInputStream(a)); int b1; 
           do {
b1=istream.read(); ostream.write(b1); } while(b1!=-1); File bla = new File("/home/bw/foofoo.wav"); 
          ostream = new BufferedOutputStream(new FileOutputStream(bla));
istream = new BufferedInputStream(file1.openInputStream(EFS.NONE,null)); do { b1=istream.read(); ostream.write(b1); } while(b1!=-1); 
         ostream.close();
         istream.close();
I tested to upload the content of a directory but it just created the dir testtest and a file with size 0B (it should be a soundfile) then exceptions occure.
URI uri = new URI("gsiftp://aliserv6.ct.infn.it:2811/dpm/ct.infn.it/home/geclipsetutor/testtest";); IFileStore fs = EFS.getStore( uri ); IFileStore homeDir = fileSystem.getStore(URI.create("/home/bw/wav/")); 
homeDir.copy(fs, EFS.NONE, null);

Maybe created with the wrong rights.
Are you able to up and download files?

Hi everybody,

I have got a probleme with (getFileStore() IFileStore to gsiftp url)

getFileStore().openInputStream(EFS.NONE, null);

This method allways return null.

The method

getFileStore().openOutputStream(EFS.NONE, null);
works like a charm. I manage to write strings inside one file, but if I try to open an inputstream to this file I get a null pointer! 

Cheers,
Rom.
