Directory management

Based on some of the other threads it appears that you're using one of our wrappers.  You can find unit tests for each of the wrappers that illustrate how each method is called.

It also appears that you have discovered the uploadHelper in the wrapper.  This is indeed the way to upload objects to Atmos using the wrappers.

Yes I’m using the UploadHelper class. Just seems extremely odd that no exception is thrown from the following call:

oId = uploadHelper.createObjectOnPath(new ObjectPath(directory), new File(fileToStore.getFileName()), null, ml);

What I’d also like to know is this:

If the above call is working correctly, should a file object be created in the directory.

That is not happening in my installation of ATMOS – I need to know if it is a config issue, an access rights issue or if I have a misconception about the functionality of the method.

Thanks

To create an object from a file in the namespace (which allows you to use directories) you should use createObjectFromFileOnPath() in the uploadHelper class.

Here's an example of calling createObjectFromFileOnPath (it's PHP but the concept, method, and parameters are identical to Java) that works by the way:

$esu = new EsuRestApi( $host, $port, $uid, $secret );
$path = new ObjectPath("/test_path/filename.data");
$upload = new uploadHelper($esu);
$file = "/home/user/filename.dat";
$oid = $upload->createObjectFromFileOnPath($path, $file);

I’m over my allotted time for working on ATMOS.

What version of the java api are you referring to?

I’ve downloaded the latest which is

EsuJava_1.4.0.29.zip

There is no method called createObjectFromFileOnPath in the UploadHelper class.

Hi Anthony,

Building on your example

directory = "/dir1/";

File = "file.txt";

oid = uploadHelper.createObjectOnPath(new ObjectPath(directory), new File(fileToStore.getFileName()), null, ml);

   If the ObjectPath has a slash at the end of it then the payload is ignored and the request is a POST to just create the directory.  If the ObjectPath is a file name like so ObjectPath("/dir1/file.txt") then file.txt will get created along with the directory dir1.

Hope this helps

thanks

Thank you. That works. Not what I would call intuitive but hey – this stuff is new …

Ahh --- I stand corrected.  createObjectFromFileOnPath() exists in the other wrappers.

I agree with you about the not-so-intuitive nature of the ObjectPath object.  I made the same mistake too, but it sorta makes sense as to why.

Just to add to what Dan said:

When you call createObjectOnPath() (intending to create a file object) the wrapper is sending this:  POST /rest/namespace/dir/path/file.txt

When you call createObjectOnPath() (intending to create a directory) the wrapper is sending this:  POST /rest/namespace/dir/

So the trailing slash is important.
