Updated Cloud Files examples

[jdaggett]

This PR updates the Rackspace Cloud Files examples to use the updated 1.7.3 APIs/release.

SmokeTest was run against the examples.

What will this print, by the way? Is there something in the container we want to get and demonstrate here?

[jdaggett]

@demobox It just prints out the Container along with its information, nothing more.

[demobox]

Just a couple of minor comments, but am also fine with this as-is. +1 - looks good to me.

Thanks, @jdaggett!

You're going to need to update the jclouds.version in the pom.xml file for these changes to work.

[jdaggett]

@everett-toews Whoops, I had it changed in my working copy but didn't commit it. Updating now, thx!

Thanks, @everett-toews - good catch! Forget to check that - assumed that had already happened. Whoops...

@jdaggett UploadDirectoryToCDN doesn't work for me as is. Can you please try it to see if it works for you and verify it by trying to go to the "Go to" URL.

This is what I had to change to get it to work.

public UploadDirectoryToCDN(String username, String apiKey) {
  RegionScopedBlobStoreContext context = ContextBuilder.newBuilder(PROVIDER)
        .credentials(username, apiKey)
        .buildView(RegionScopedBlobStoreContext.class);
  blobStore = context.blobStoreInRegion(REGION);
  cloudFiles = blobStore.getContext().unwrapApi(CloudFilesApi.class);
}

and

private void uploadDirectory(String dirPath, String container) throws InterruptedException, ExecutionException {
  File dir = new File(dirPath);
  checkArgument(dir.isDirectory(), "%s is not a directory", dirPath);

  System.out.format("Uploading %s to %s", dirPath, container);

  Location location = Iterables.find(blobStore.listAssignableLocations(), new Predicate<Location>() {
     public boolean apply(Location input) {
        return REGION.equals(input.getId());
     }
  });

  blobStore.createContainerInLocation(location, container);

  List<BlobDetail> blobDetails = Lists.newArrayList();
  generateFileList(dir, "", blobDetails);
  uploadFiles(container, blobDetails);
}

Try it with those changes and see if it works for you.

@jdaggett I need this stuff right now so I'm going to merge it and make the updates.

[etoews]

Merged.

[gaul]

You can avoid the conversion to and from a String with:

Payload payload = blobStoreContext.utils().http().invoke(request).getPayload();
Files.write(payload, file);

[etoews]

I'll update that in my new (pending) PR.

Fixed in #51
