Remote files PUT

I'm having troubles to upload files from a client's machine to Slide 
server. Locally (from the server), using WebdavResource.putMethod
(String, File). There was no problem, but, remotely, using 
WebdavResource.putMethod(String, InputStream) it didn`t work. In a 
particular case, uploaded zip files are empty, or have an "unexpected 
end of file reached". Any help?

Here is my code....

public String altaPaquete(String psNombre, InputStream poFile) throws 
        TPaqueteNoSubidoException {
    if(poFile != null){
        String lsServerRoot = getServerRoot() + ":" + getServerPort() 
+ "/";
        HttpURL loURL = new HttpURL(getServerRoot()+ ":" + 
getServerPort());
        boolean lbExito = false;
        WebdavResource loRemoteFile = null;
        try {
            loURL.setUserInfo(getUserName(),getUserPassword());
            loRemoteFile = new WebdavResource(loURL);
            lbExito = loRemoteFile.putMethod(getServerPath() + 
psNombre, poFile);
            loRemoteFile.close();
        } catch (MalformedURLException e) {
            throw new TPaqueteNoSubidoException("URL mal formada", e);
        } catch (HttpException e) {
            throw new TPaqueteNoSubidoException(e);
        } catch (IOException e) {
            throw new TPaqueteNoSubidoException(e);
        }
		    
        if(lbExito){
            return lsServerRoot + getServerPath() + psNombre;
        } else {
            throw new TPaqueteNoSubidoException("No se pudo guardar el 
archivo");
        }
    } else {
        throw new TPaqueteNoSubidoException("No se puede leer el 
archivo");
    }
}

... and the invocation

public void testAltaPaquete(){
    try{
        File fn = new File("c:\\Test.zip");
        FileInputStream loStream = new FileInputStream(fn);
        AccesoPaquetes loServer = new AccesoPaquetes(
                                                                
SERVER_ROOT,
                                                                
SERVER_PORT, 
                                                                
SERVER_PATH, 
                                                                
USER_NAME, 
                                                                
USER_PASS
                                                        );
        String lsURLEsperada = SERVER_ROOT + 
                                           ":8080/" + SERVER_PATH 
                                          + coFile.getName();
        String lsURL = loServer.altaPaquete(fn.getName(), loStream);
        assertTrue(lsURLEsperada.equals(lsURL));
    } catch (TPaqueteNoSubidoException ex){
        fail(ex.getMessage());
     } catch (FileNotFoundException ex) {
        fail("Archivo no encontrado");
     } 
}

This ends succesfully, with no fail.

Thanks a lot,
