Re: [Dev] OAuth2 introspection endpoint with token_type_hint parameter
Hi Nilasini and Farasath,
Thank you for your assistance.
I checked with WSO2 IS 5.8.0 RC1 and it is fixed.
Thanks,
Chanaka

[Dev] OAuth2 introspection endpoint with token_type_hint parameter
Hi all,
I encountered an issue when trying to Invoke the OAuth2 Introspection
Endpoint of WSO2 IS 5.7.0 as guided by the doc [1]. These are the scenarios
I tried a valid token, and a part of the response status:
1. Invoke introspection endpoint with the *token. *Response -
{"active":true}
curl -k -u admin:admin -H 'Content-Type:
application/x-www-form-urlencoded' -X POST --data
'token=334060588-dd4e-36a5-ad93-440cc77a1cfb'
https://localhost:9443/oauth2/introspect
2. Invoke introspection endpoint with the *token* and *token_type_hint*=
*bearer*. Response - {"active":true}
curl -k -u admin:admin -H 'Content-Type:
application/x-www-form-urlencoded' -X POST --data
'token=334060588-dd4e-36a5-ad93-440cc77a1cfb&token_type_hint=bearer'
https://localhost:9443/oauth2/introspect
3. Invoke introspection endpoint with the *token* and *token_type_hint*=
*access_token*. Response - {"active":false}
curl -k -u admin:admin -H 'Content-Type:
application/x-www-form-urlencoded' -X POST --data
'token=334060588-dd4e-36a5-ad93-440cc77a1cfb&token_type_hint=access_token'
https://localhost:9443/oauth2/introspect
According to the OAuth2 token introspection specification [2],
If the server is unable to locate the token using the given hint,
it MUST extend its search across all of its supported token types.
So, according to the specification, It should send the active parameter of
the response as true in the 3rd scenario.
Appreciate your thoughts on this.

Re: [Dev] GSOC 2017 - Native inbound and connector for FTP/SFTP operations
Hi Malaka, Thank you for the response. When searching for Java FTP/SFTP libraries I found out that there are only a very few libraries built on top of NIO. But each of them had few limitations. So, I could not find any other fully-supported and suitable library built on top of NIO. When considering about Apache Commons Net [1] it supports FTP and FTPS, but it does NOT support SFTP. Will that be a problem to us? My research found out that the best and most widely used library for FTP/SFTP is JSch [2]. I worked with it during my industrial training and it seems to fit for our requirements and it is widely used in the industry too. As I said earlier, with the use of those findings I created a comparison on SSHJ, Apache Commons VFS and JSch and published on my blog [3]. This blog article [4] also says about the author's experience in FTP/SFTP using different libraries and there were many other similar articles by different authors. What do you think about using JSch? Can we use commons-net when it doesn't support SFTP? [1] https://commons.apache.org/proper/commons-net/ [2] http://www.jcraft.com/jsch/ [3] https://medium.com/@ldclakmal/comparison-of-commons-vfs-sshj-and-jsch-libraries-for-sftp-support-cd5a0db2fbce#.t09zd4zr5 [4] http://www.onkarjoshi.com/blog/126/which-library-to-use-for-ftp-sftp-ftps-file-transfer-in-java/ Thank you.

Re: [Dev] GSOC 2017 - Native inbound and connector for FTP/SFTP operations
Hi Malaka, I researched for the Java NIO FTP library that you suggested for me [1]. What I found was that this is a code base with a very short history and the most recent commit was over 13 years ago by Torvald Riegel who was the only contributor to this [2]. I feel like this is not an ongoing project and not supported by the author. What do you think? And I couldn't find any documentation regarding that library. Although I went through each and every Java class of this library, I couldn't find a way to get the use of this library without a API reference or documentation. I would be glad if you could share some additional materials if you have or any suggestions to get a better approach to this project.

Re: [Dev] GSOC 2017 - Native inbound and connector for FTP/SFTP operations
Hi Malaka, I researched for the libraries that we can use for FTP/SFTP operations in addition to using Apache Commons VFS. I found out about some widely used libraries such as SSHJ [1] and JSch [2] and did a comparison among them. With the use of those findings I created a comparison on SSHJ, Apache Commons VFS and JSch and published on my blog [3]. Also, I have experience in JSch since I had previously worked on developing a SCP transport using JSch [4] [5]. I believe its ability to execute shell commands with the help of the library is a great feature in JSch. According to the comparison and my experiences, JSch looks like the best candidate among them and I hope to hear others' thoughts about this.

Re: [Dev] GSOC 2017 - Native inbound and connector for FTP/SFTP operations
Hi Malaka, Thank you for your response. As you mentioned, you have done a similar development to optimize and manage local file system using Java NIO [1] instead of Commons-vfs. [2] So my goal is to find such mechanism which is more unique to ftp/sftp protocol, in order to support file operations via ftp/sftp protocol. So, I will come up with my suggestions with best mechanism that is to be used for file operations via ftp/sftp protocol rather than Commons-vfs. Please share if you have any recommended methods or suggestions to get a better approach to this project. Also I do confirm that I am a full time student and eligible to participate GSoC.
