[Dev] [IS] Returning to application with authentication failure state

[Danushka Fernando]

Hi All

I am trying to work on $subject. While looking in to $subject I found a
status in AuthenticatorFlowStatus class named FAIL_COMPLETED but we haven't
used it in the code. So even from the authenticator I set that value it
won't take an effect. I guess we should have use that state and since we
are using same framework for IS 6 shall we do that for IS 6?

Meanwhile have anybody tried to achieve this in IS 5.x and succeeded? Any
ideas are appreciated.

Thanks & Regards

Re: [Dev] How can I add a registry resource using registry REST API?

[Shazni Nazeer]

Sequences are raw registry resources. In that case you can't use the
Governance REST API. You'll probably have to use WSRegistryServiceClient in
a Java client.

 It seems registry REST API is not there in API-M 1.10.

 Using the following command I can get a registry resource in API-M 1.10

 curl -X GET -k -H "Authorization:Basic YWRtaW46YWRtaW4=" "
 https://127.0.0.1:9443/registry/resource/_system/governance
 /apimgt/applicationdata/provider/admin/CalculatorAPI/1.0/in/
 cal_log_in_message"

 Similarly, how can I add/update a resource?

 Thanks.

Re: [Dev] [GSOC][CEP][DEV] Python API for Siddhi CEP

[Madhawa Vidanapathirana]

Hi,
Thank you for your quick reply.

Since directly using Siddhi Library is the more general case, I'll first
focus on it.

1) I am thinking about following the same structure in JAVA API, centered
around Siddhi Manager. Any opinions on this?
2) Any idea on extent to which lower level/internal components should be
exposed? (e.g. - Exposing "StreamDefinition" class in addition to creating
stream via Siddhi query using "siddhiManager.createExecutionPlanRuntime").
I have heard that it is usually discouraged to use lower level components
instead of the query approach.

Will try to send you a prototype covering basic functionality through
Siddhi Java API, before making the proposal for entire project.

Still cause.getTargetException() gives original exception, how can we get

[Dev] How to Wrap Java Exception in UUF

[Gayan Gunawardana]

Hi UUF team,

Client OSGI service throw  UserPortalUIException with error message
(message) and error code (errorCode).

String error = "Failed to update user password.";
LOGGER.error(error, e);
throw new UserPortalUIException(error, e.getErrorCode());

Form client side .js I can retrieve error message as below

} catch (e) {
var message = e.message;
var cause = e.getCause();
if (cause != null) {
//the exceptions thrown by the actual osgi service method
is wrapped inside a InvocationTargetException.
if (cause instanceof java.lang.reflect.InvocationTargetException) {
message = cause.getTargetException().message;
}
}

Is there a way to retrieve errorCode as well ?

Thanks,
Gayan

Re: [Dev] [IoTS] Cannot enroll new device with the new created account

[云展智创]

Hi Harshan,

I just created the account in the register link. I can’t select the role by 
myself. In the previous IoTS version, the server will provide a default role 
(maybe devicemgt-user) to the new registered user but not in IoTS 3.0.0.

I need to manually create a new role and assign the user to the role with admin 
user so that the new user can enroll new device. Is that right?

Thanks.

It is great to see your interest on this project, let me provide some
context.

- Feature wise outcome of this project should be equivalent to current
WS-Trust implementation of WSO2 IS which is based on Apache Axis2 web
service stack, If you haven't already try out current implementation please
download WSO2 IS 5.3.0 version and familiar yourself about current
implementation. Following pages may help [1] [2] and you can find some good
resources on web as well. This is the necessary 1st step to start this
project.

- As 2nd step it would be better of you can try out Apache CXF samples and
their architecture on WS-Trust implementation.


- In current WSO2 IS implementation which based on Carbon 4 platform, Axis2
web service engine is OOTB available but IS 6 which based on Carbon 5
platform does not provide any WS engine. This is the major architectural
change cause to re-implement  WS-Trust for IS 6.

- As mentioned there is no WS engine in IS 6 but it has cool REST framework
(WSO2 MSF4J) available OOTB, so we can reuse MSF4J to handle transport
(HTTP/S) related activities of new WS-Trust implementation without bringing
any new transports. In others words we don't need to use any CXF transport
for this project, ideally MSF4J can accept HTTP messages and then it can
delegate messages into CXF engine for processing ( without going through
CXF transports ).

- Scope wise this is well defined we need same level of functionalities as
current IS 5.X implementation.

- Implementation wise this is not very hard but design the proper solution
needs some effort and time so it's an advantage to start the design as
early as possible.

I believe now you have enough information to start, if you need further
clarifications please don't hesitate to contact us.

Re: [Dev] [GSoC 2017][ESB]Native inbound and connector for FTP/SFTP operations

[Hasitha Jayasundara]

Hi all,

On my research I found many java SSH libraries that support SFTP.The main
differences between these libraries can be given as,

   - client authentication over password / public key
   - server authentication
   - upload /download files from local host over SFTP
   - download files to local host over SFTP
   - file operations on the remote host like move, delete, list all
   children of a given folder (filtering after type like file or folder) over
   SFTP
   - execute plain shell commands

Considering the popularity and the ease of implementation JSch and SSHJ are
the best libraries I found other than apacheVFS .The details on how these
libraries differ from each other according to above mentioned points are
included in the following link.[1] Currently the implementation only
supports apache-vfs.I will update my implementation with JScH and SSHJ soon.

Thanks

Re: [Dev] [GSoC 2017][ESB]Native inbound and connector for FTP/SFTP operations

[Hasitha Jayasundara]

Hi all,

I 've added sftp support to the implementation [2] in order to get an idea
about how apache vfs is used in file transferring.I used
com.jcraft(jsch),apache.commons and commons-logging dependencies in the
implementation which you can find in the pom.
To run the program,

1.Add server details to the SFTPProperties.txt

serverAddress=[server address]
userId=[userId]
password=[user password]
remoteDirectory=[Remote folder name]/
localDirectory=/LocalSFTP/  *don't change this

You can simply setup a openssh sftp server [1] and add the credentials to
the txt file above mentioned
Your local file folder is LocalSFTP.Add files you want to exchange in that
folder.
Your remote file folder is [Remote folder name](You can create a folder
with a name you preferred in the server)

2. Build the pom.xml
3. Run the scripts SFTPDownload.java and SFTPUpload.java

 Hi Malaka,

 Sorry for the late reply.

 I studied the implementation of ESB connectors[1],File Inbound
 protocol [2] and now I have a fully understanding about the project 
 and the
 deliverables. As the description of the project states I'll update the
 thread with my findings on methods to to be used for file operations 
 via
 ftp/sftp other than Apache-vfs.

 (I do confirm that I am a full time student and eligible to

Re: [Dev] [IS] No of failed attempts in an authentication framework

[Hasintha Indrajee]

You can capture successful as well as unsuccessful login attempts through
an extension point in authentication framework. For an example please refer
the audit logger we have implemented in [1]. But your requirement seems
different. If you are implementing a custom authenticator for this, you can
keep track the failure count within authenticaitonContext and redirect to
the application if the number of failures exceeds your threshold value.

Re: [Dev] Environments Support for WSO2 API Manager

[Ravindu Perera]

Hi All
I have actually gone thought the instructions given I want to get a problem
clarified. I researched and found that from the store APIs can get which
environment the currently the API is in , or is it when i am publishing the
API i should get the environment.

question 1
Which one of these methods are the best approach or if i am wrong can you
all please help me in-order to find the correct approach to get which
environment . the current API are in .

question 2
In the API store of the API manager , is there a specific way to show the
Environment (example should it be with API description )
can you please elaborate more on how should the environment should be
present in the store.

think you all will help me to find answers for the questions , these
information will be helpful in writing the proposal and also making and
proper planning for the project.
Thank you

Re: [Dev] [GSoC 2017][ESB]Native inbound and connector for FTP/SFTP operations

[Hasitha Jayasundara]

Hi Malaka,

No need to install any Server locally.You can find the server
implementation in FTPServer.java.

1. Run FTPServer.java
2. Run FTPClient.java
3. In the folders Client and Server include the files you need to exchange.
(Change file paths according to your development environment
  eg - File f=new File("Add your file path/Client/"+fileName);
 File f=new File("Add your file path/Server/"+fileName);)
4.In FTPClient.java console you can find
  1.SendFile
  2.ReceiveFile

Include the number of the operation you need.(eg - 1 for SendFile, 2 for
ReceiveFile ).And you can see it's working.(Include files inside Client and
Server folders.Otherwise the console would outputs "File not found").

 Hi Chanaka,

 Thank you for your interest in this project.

 Currently with WSO2 ESB there is a generic JMS inbound endpoint that
 can be used to consume messages from different brokers. [1]

 However there are complexities when configuring WSO2 ESB with IBM MQ.
 This is mainly due to class loading issues. Also IBM provides more
 customized options that are written on top of JMS transport.

 Part of this project is to identify those and develop a new Inbound
 Endpoint to support this integration.

 Also please confirm that you are a full time student and currently not
 employed since it is against GSoC rules.

Re: [Dev] [GSoC 2017][ESB]Native inbound and connector for FTP/SFTP operations

[Malaka Silva]

Hi Hasitha,

How did you test the sample?

Did you install a FTP/SFTP server locally and try this use case?

 It's ok to pick one of the local cache implementations but make sure
 you discuss with others without limiting to your own use case and pick a
 good one so that others can use the same for their local caching
 requirements, it's really ugly to use several local caching F/W across the
 platform other than really exceptional cases.

 Thanks !

Re: [Dev] GSOC 2017 - Native inbound and connector for FTP/SFTP operations

[Chanaka Lakmal]

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.

Please share your recommendations and suggestions to get a better approach
to this project.

 Hi,

 I'm interested in the project *Native inbound and connector for
 FTP/SFTP operations*. I would like to know more information regarding
 this.

 I am Chanaka Lakmal, an final year undergraduate from Department of
 Computer Science and Engineering, University of Moratuwa. I have the basic
 knowledge on Java NIO, File Systems and I have been working with ESB and
 connectors.

 Initially I went through following [1] to understand about File Inbound
 Protocol and I would like to know more about this project, especially on
 the expected outcomes and the scope of the project.

Hi Hasitha,

Yes that's the idea. You can get familiar with Tensorflow JAVA API through
[1] and [2], and refer [3] to learn more about tensorflow.
Please feel free to contact if you have any suggestions or problems.

https://www.tensorflow.org/api_docs/java/reference/org/tensorflow/package-summary
[2] https://github.com/tensorflow/tensorflow/tree/master/tensorflow/java

 2017.I was an intern at WSO2 for 6 months and successfully completed Image
 processing module(4th sem) in university.Please provide me some guide
 lines and additional materials for study and get a clear understanding
 about the mentioned project.
