I've been trying to figure out how to download multiple files in a row based on the SimpleFTPSample provided by apple. Basically, I'm filtering what the user can see when they browse an ftp server, but when they select a certain file type, I want it to automatically check for another file of the same name with a different extension and if it exists, download it as well. I can't seem to get this second file to download no matter what I do. It seems strange because if I select two files in a row in my tableview, it downloads both of them just fine. Any ideas?
Edit:
It's just the SimpleFTPSample from apple.developer.com, all I did was create additional NSInputStream and NSOutputStream objects and I created a new _startReceiveFile method that gets called from _startReceive if I'm downloading a file instead of getting a directory listing. _startReceiveFile is the same code for _startReceive in the file download code for the sample project, except if the file to download has a certain extension, it also downloads an additional file with the additional stream objects. Let me know if I need to clarify more or try to put together a clear example.
Well, since there were no takers, I'll just post my solution here. I've abandoned trying to download two files at once. Instead, I just keep the ftp browsing window open and only handle the opening of the file once both files have been downloaded (user has clicked on each one separately). It's not what I wanted, but it will work, at least until I can figure out how to get two files with one request.

I want to know if there is a 'right' way to make file uploads through custom tools.
I've seen the https://confluence.sakaiproject.org/display/BOOT/File+Uploads+with+RSF guide and it seens ok, but It stops with the file in memory with no further info. I can built a random file upload code but I want to make it Sakai-friendly (Using ContentHosting and Resources service?)
Any hints?
Thanks
The link you provided for the first part is a good example of how to get the upload initially processed. Going through RequestFilter will get your files validated, but you can use whatever method you want to upload it.
For the second part, I'd look at the ContentHosting webservice (createContentItem) for an example of how to add a file from a byte[] in memory after you've uploaded it.
These methods in ContentHostingService also accept InputStream as a parameter as of 2.7 (KNL-325), so you don't have to store the entire file in memory and can stream it as you're uploading, which you should do if the files are of any reasonable size.
I'm hoping someone can help. I've started using the Community TFS Build Extensions, in particular the FTP activity. I followed the documentation here and got to grips with the it pretty easily. I'm encountering one major problem though.
My Web app has a basic enough structure:
I start by creating the FindMatchingFile activity which places the files in the drop location into an IEnumberable variable called FilesToFTP :
String.Format("{0}\**\*.*", BuildDetail.DropLocation)
When I iterate through the variable and print out the results, all seems correct:
G:\builds\Build.1203\CredentialManagement\bin\BusLogic.dll
G:\builds\Build.1203\CredentialManagement\css\style.css
G:\builds\Build.1203\CredentialManagement\AppError.aspx
......
G:\builds\Build.1203\CredentialManagement\Web.config
etc etc.
The problem is, when I pass that IEnumerable to the Ftp activity (converting it to a string array), it FTP uploads all the files on the server however it doesn't keep the directory structure of my Web app. It just piles all the output (dlls, aspx etc) into one directory. See the following two screenshots.
Is there any way I can use the FTP activity to upload all the output from the drop location recursively? I feel like I'm doing something simple wrong.
The FTP activity in TFS Build Extensions doesn't upload files recursively.
I think it would be a good value addition to the activity. Please create a request for the project and we will add in it. For now, you can go around it by calling the Ftp activity recursively for each directory and setting the RemoteDirectory for each.
I would like a better workflow for debugging uploaded SCOs. As things are, I must edit a file in the activity, repackage, upload, and test. Often, I just need to change a single line of code. It would be VERY nice to be able to edit that file, that line of code, on the server. So far, all I've found is that Moodle manages the files, so it seems impractical to locate and decipher the renamed files after upload.
Is there a way to configure Moodle so that it doesn't rename and relocated files in SCOs upon extraction? Actually, I'm open to any suggestions on the best, fastest workflow for debugging SCOs.
Problem background
Since Moodle 2.0, files are no longer stored on server in the conventional /this/is/the/path/to/my.file way. Instead, files are rehashed and stored in Repositories (i.e. spread all over the moodledata folder as a collection of seemingly random data). This increases security and cross-OS compatibility but complicates stuff for people who would like to simply upload a SCORM zip package via FTP. Here's more information on file handling in Moodle 2.0
Path to the soluton
Let's locate the file you want to update, then update it.
Run phpmyadmin, go to mdl_files table, find your file by name in the filename field (let's say it's portrait.jpg)
Look at the contenthash field, it'll look like abcde1234567890. This means your file is stored in moodledata/filedir/ab/cd/ folder under the name abcde1234567890.
Rename the updated portrait.jpg to abcde1234567890, upload and overwrite.
Go back to phpmyadmin and update the filesize field in record for portrait.jpg with the size of the updated file.
Obviously, this process can be automated. You'll have to write a script that allows you to upload a file, then it'll search for that file in mdl_files, save it to the correct folder and update all fields accordingly.
Alternative idea
Enable external package type (and also enable 'Update on every launch'). Go to Site administration / Plugins / Activities / SCORM and check the box down below. Now you'll be able to launch SCORM packages directly from another server, so Moodle won't mess with it. Of course, you can run in other (probably cross-domain related) problems.
Sergey's answer is very good, with one caveat:
In his example with the contenthash of abcde1234567890, the file is stored in the moodledata/filedir/ab/cd/ folder under the name abcde1234567890. Moodle uses the full contenthash to name the file.
Recently I've integrated Google Drive with my iOS application. Everything works fine but .ppt files. Normally if a file is a Drive file I use downloadURL to download it. If the file belongs to Google Docs I use one of the exportLinks (exactly the same as Alain described it here).
However all .ppt files (with "mimeType": "application/vnd.google-apps.presentation") which come from Google Docs are corrupted after being downloaded (I use an export link with exportFormat=pptx). The same file downloaded via web browser works fine.
I use ASIHTTPRequest lib for downloading files (which also can be the reason of corrupted .ppt?).
Any ideas why only ppt files cause problems?
I can already tell you that the lib you're using isn't the cause:I'm not using it but I've the same problem: it seems that there the code received isn't 200 (if ($httpRequest->getResponseHttpCode() == 200)) as it shows me a specific error message I've asked to return in case of. Also, when I'm trying to download a presentation in PDF or txt, it shows the same error.
It's not really an answer but I'm trying to understand also why only presentations are causing problems.
EDIT: the code received is 302. If it can help...
EDIT 2: After trying, I noticed that the first parameter is the file id and the second the export format:
https://docs.google.com/feeds/download/presentations/Export?docId=filedid&exportFormat=pptx
But in the 302 code, I have this location:
https://docs.google.com/feeds/download/presentations/Export?exportFormat=pptx&id=fileid
Not only the two parameters aren't in the same order but the name is id and not docid
When I take this URL, put it as the export link and then try to copy the file, it's working. I get a 200 response and the inside of the file.
I hope it helps.
How do you distribute other files needed by your application that aren't in a jar file? For example, the application at http://www.javabeginner.com/java-swing/java-swing-shuffle-game . The download contains Shuffle.jar, Shuffle.bat, Score.dat, and an images folder with 3 images in it. I can see possibly putting the images directly in Shuffle.jar, but you wouldn't want to put Score.dat in the jar file because it changes. Is there somewhere you could identify this type of file in the jnlp?
The non-java files should be stored as resources. For files that change, you store the original or template file also as a resource in your jar. When the program starts, you have it check the local system to see if that file exists. If not, it creates the local file by copying the template file from the JAR resource. If the file already exists, then it is used as is.
To save files to the local system, even when running in the sandbox (unsigned), you can use the PersistenceService (javadoc / example). If your java application is signed, then you can use the regular File apis to write the file to the local machine, such as in a ".yourgame" subfolder under the user's home folder.
You can put all those files (except the scores file) in your jar file and load the contents using resource loading.
I've just deleted and restarted my reply twice now, changing my answer each time; this is confusing and needs a bit more clarification.
Are you SURE that application is supposed to be a Web Start app? On the site you linked to, it doesn't appear to be. Are you trying to take an application that was not designed as a Web Start application and change it into one that can be Web Start?
If it's not a Web Start app as your tag implies, then this question is open ended. You can distribute it 100 different ways.
If you are indeed trying to convert it into a Web Start app, you can start by packaging the images into the jar and that will alleviate your first headache if you just read them from there instead of from a File(). If it's going to be Web Start, then you need to decide how you want to keep scores. You have to decide what the scoring system is like before you can decide on how to go about it; will all the scores be kept on the web site hosting the Web Start app? Will that part still be local? If you want to get access to the local file system, you need to sign the jar, then you can extract the score.dat to the file system and do whatever you want with it if the end user accepts.
You need to figure out what you want to do before you can do it, or at least clear it up for us if you already know more than we know you know.
