Hi Supun,
Thanks! I have checked code and looked into the GuiFileUploadTask and further plan to replace the same connector code with the API that will connect with the nextcloud server. If I am not wrong, seadgrid.properties has the details of the file server where the input files are uploaded. I believe the Airavata API will pick up the input files from the current remote server that is configured in the seagrid.properties and do you have any suggestions about how the output files are written or downloaded from the remote server? There is another file called GuiFileDownloadTask in the same storage path, I believe this will download the files when the experiment is completed, and to be sure the Airavata is writing the output files to the same remote directory?

To make your life easy here are some code pointers :) The SFTP integration code is located here https://github.com/SciGaP/seagrid-rich-client/tree/master/src/main/java/org/seagrid/desktop/connectors/storage. Specifically the file manager api methods are implemented here https://github.com/SciGaP/seagrid-rich-client/blob/master/src/main/java/org/seagrid/desktop/connectors/storage/StorageManager.java. For the SFTP authentication, the current client uses the OAuth token given by the SciGaP identity provider as the password. The Username is same as SEAGrid username. As per the current implementation (someone please correct me if this has been changed recently) Airavata GFac requires the file paths to be absolute paths. However, the SFTP server provides a virtual file system view the root directory is actually a directory named by the username in the host file system. So there is some file path conversions happening between SFTP paths and paths used when creating experiment metadata. This can be configured here https://github.com/SciGaP/seagrid-rich-client/blob/master/src/main/resources/seagrid.properties#L43 On Tue, May 15, 2018 at 7:44 PM, Kotabagi, Karan <kkota...@iu.edu<mailto:kkota...@iu.edu>> wrote: Hi Supun, Please find the following answers to the questions: 1. As per my knowledge resumable uploads for the Nextcloud has been implemented at the client side, I still need to check regarding the same with respect to the server side implementation. Reference: https://github.com/nextcloud/android/issues/159 2. Nextcloud can be integrated with the third-party authentication schemes using OAuth/OpenID.

Does NextCloud support resumable file uploads? (Meaning you can upload part of the file now and the rest later) 2. Can we integrate NextCloud with third-party authentication schemes using OAuth/OpenID?

You may need to create an account there (if you don't have one already) and get it approved. Until your account is approved you will not be able to login. BTW, is your project proposal publically accessible?

I am starting to work with the Seagrid rich client Java Fx application to replace the airavata file manager with the Nextcloud. I followed the build steps in the readme file of the github repo https://github.com/SciGaP/seagrid-rich-client First, I was able to run the script as in the jamberoo-libs directory and execute "mvn_install_libs.sh" Next, I am able to build the project successfully with the command "mvn -P update-deployment clean package" I was able to build a native installer with the command "mvn -P update-deployment install" and run the app at the path "seagrid-rich-client/target/installer/fxlauncher.jar", I believe this is the right jar file to start the application. I was able to start the application as attached in the screenshot "desktop_client.png". Although, I am not able to login to the application with the CLI login, my next task would be to figure out on how to login to the application and test the sample upload of the files. Do the client applications have the separate authentication system? Would I have to request the separate access for the separate clients? If yes then where can I request the access for this Seagrid javaFx desktop application? Regards Karan
