Re: [Dev] String plus compiles to append

[Manuranga Perera]

My comment is about using plus out side of loops. Obviously we should use
StringBuilder when using loops. But we shouldn't uses it unnecessary
outside of loops since it affects readability.

Re: [Dev] [AppFac][Docker]Best Java Docker Client Library

[Roshan Deniyage]

Hi Samith,
If we use a docker plugin, it becomes a part of build job so, need to
generate the docker file before the build starts. If we use the existing
appfactory jenkins plugin, we can generate the docker file and call the
docker commands after the build is finish inside our plugin. Docker related
steps are called when deployment is happen.

Re: [Dev] HTTPS REST Client

[Malmee Weerasinghe]

Hi Dharshana,
I tried with what you suggested. But I still get the same error.
ppaas-artifact-converter tool doesn't run on Carbon and it runs
independently. Therefore for "System.getProperty("carbon.home")" it returns
null. I tried copying this file, "wso2carbon.jks" to the resources folder.
But I get the same error.
Thank you.

 As you can see, there are three appends but only one StringBuilder

Re: [Dev] [DEV][IS] Getting an Unique index or primary key violation exception.

[Kamidu Punchihewa]

Hi IS Team.

The above error occurs in the 1st token expiration time also,with on device
calling a singleton token refreshing call to IS.
This happens when EMM android agent try to acquire a new set of token on
the access token expiry using the refresh token grant.

This Issue Started after the IS version bump from 5.0.3-SNAPSHOT  to 5.0.3.

Code Snippet which initiate communication with IS is given below.








*var xMLHttpRequest = new XMLHttpRequest();var tokenEndpoint =
mdmProps.idPServer + "/oauth2/token";xMLHttpRequest.open("POST",
tokenEndpoint, false);xMLHttpRequest.setRequestHeader("Content-Type",
"application/x-www-form-urlencoded");xMLHttpRequest.setRequestHeader("Authorization",
"Basic " + clientData);var url = "grant_type=refresh_token_token="
+ tokenPair.refreshToken;if (scope) {*

*url = url + "=" + scope*



*}xMLHttpRequest.send(url);*

Thanks & Best Regards.

Re: [Dev] [DEV][IS] Getting an Unique index or primary key violation exception.

[Kamidu Punchihewa]

Hi Johann/IS Team,

As per the discussion i had offline earlier above exception occurred under
heavy loads.

The above exception occurred without any high loads in the system.
When one devices logged in for some time, without any concurrent calls to
IS, this exception is given to the device.
Any idea why this happens with one device acting alone.

Thanks and Regards.

[Dev] Fwd: [API Manager] Creating android Client sdk using swagger source code

[Randika Navagamuwa]

Hi all,
   I'm trying to come with a solution to reduce the complexity of
developing android apps. I found out that it would be better to integrate
the solution with API manager.

   - User should be able create APIs.
   - Then when he is using those APIs, Android client sdk should be
   generated automatically.

Since first part is already there in the API manager, I'm more concerned
about the second part. Android client can be generated easily using swagger
*codegen*.
According to my knowledge swagger source file is generated by API manager
after creating the API. We should be able to generate the client side code
using that *swagger.json* file. But the problem here is when I create the
client code some classes are missing.

  I think it's not working because

   - There should be more in the json to create the client side code.
   (Swagger definition is incomplete)

I just want to clarify whether I'm correct or not and is it possible to
implement that?

Thanks,
Randika

We have already removed RMSequence mediator in 4.9.0.
I haven't seen anyone using Enqueue Mediator in a real use case.

I think we should deprecate Topic feature and Event Mediator as well.

Re: [Dev] HTTPS REST Client

Any reason to building a HTTP client from scratch? Why don't we use
existing libs such as HTTPClient or Netty?

 Hi Malmee,

 The SSL issue comes with the rest client is because you are going to
 invoke HTTPS backend with out proper certificate in path.

 you can set keys to the system path using following

 String trustStore = System.getProperty("carbon.home") + File.separator + 
 "repository" + File.separator +
 "resources" + File.separator + "security" + 
 File.separator + "wso2carbon.jks";
 System.setProperty("javax.net.ssl.trustStore", trustStore);
 System.setProperty("javax.net.ssl.trustStorePassword", "wso2carbon");
 System.setProperty("javax.net.ssl.trustStoreType", "JKS");


 In this sample WSO2 carbon keys set as keys to the system path you can use 
 the same.

 Apache HTTP client is bit old client instead you can try some thing like 
 JAX-RS 2 or RestEasy client.

 In All these clients you need to add above code segment to export keys to 
 call secured HTTP call.


 Thank you,

 Dharshana.

Re: [Dev] [DS][DAS] Sample for DashboardServer - How to get back-end url, username, password for DAS to invoke DAS rest API from jaggery file

[Supun Sethunga]

Hi Rajeenthini,

Instead of the DAS REST API, you can use the "Analytics javascript API"
[1]. This should eliminate the requirement of needing user-credentials. (or
doesn't need to send an Authorization header)

[1] https://docs.wso2.com/display/DAS300/Analytics+JavaScript+(JS)+API

Supun

[Dev] Can we suppress DAS message for schedule task execution?

[Sumedha Rubasinghe]

It can fill up the logs quite easily when there are lot of scheduled
scripts running @ low intervals.

As an alternative,
Make it a DEBUG & have an UI option to see when was the script last ran.

Re: [Dev] [Architecture] [ESB] Deprecated features in ESB 4.10

[Prabath Abeysekera]

I agree with Cyril.

In addition to what's already been mentioned, I don't think it's a good
idea to make mediation threads blocked for database calls, etc via
DBLookup/DBReport for longer periods of time, as most of the queries that
are usually being used in pretty much any practical enterprise integration
scenario would be time-consuming, particularly as respective data-stores
get occupied of large volumes of data, over time. ESB, as quite being used
as a backbone of any system that connects multiple disparate systems
together via mediation, etc, letting its core blocked for such an
environment isn't quite good, IMO. Instead, I believe, a better option
would be to delegate the same responsibility to the data layer, which can
then be scaled up and tuned to deal with similar instances.

Cheers,
Prabath

Have you seen *Enqueue* and *RMSequence* mediators being used when
implementing mediation logics?

Hi All,

May I know whether we are supporting jtds driver for MSSQL? Is it
recommended to use jtds driver?

Yeah, things should work OOTB with JTDS driver too. If you come across any
issue while testing with the same, please do raise JIRAs as appropriate.

 Hi Malmee,

 If you have used java built in methods, that would mean your tool would
 not be required to depend on an external library such as Apache HTTP client
 as you have mentioned. This is fine for a simple use case. However, please
 note if you need more functionality, such as support for all HTTP
 operations, and other capabilities, etc. it would be advisable to use
 Apache HTTP client or any other suitable existing library without
 implementing it again by yourself.

 For the certificate issue that you are getting, its possible to
 override the default certificate validation mechanism and plug in your own
 implementation which can disable certificate validation (for testing
 purposes). For HTTP Client 4, please see [1].

Hi Malmee,

You have to replace the cert location with actuvel .srt file you have.

Thank you,

 Hi All,

 We have developed a HTTPS REST client using java in-built methods which
 works properly. [1] This method is configured to allow self signed
 certificates.

 When using apache http client we get a certificate error :
 javax.net.ssl.SSLPeerUnverifiedException: Host name '192.168.30.227'
 does not match the certificate subject provided by the peer (CN=localhost,
 O=WSO2, L=Mountain View, ST=CA, C=US).

 What would be a good choice? Using apache HTTP client or java in built
 methods. Your suggestions are highly appreciated.

[Dev] [DS][DAS] Sample for DashboardServer - How to get back-end url, username, password for DAS to invoke DAS rest API from jaggery file

[Rajeenthini Satkunam]

Hi all,

Currently I am working on creating sample for dashboard server with DAS
integration.I need to invoke DAS rest API from Jaggery file(sample.jag) to
get some data.As per documentation[1] of DAS rest API we need to send
authorization header along with request to fetch data from DAS. So for
workaround I have hard-coded the username password values to variable and
concatenate them as username + ":" + password and encoded them then send as
a authorization header.Here I need to get server username and
password(credentials).IMHO it is not good practice that hard-coding
credentials of server.
I have shared my Jaggery code below

try {
var username = "admin";//hard-coded value of username
var password = "admin";//hard-coded value of password
var tableName = request.getParameter("tableName");
var query = request.getParameter("query");
var url = "https://localhost:9465/analytics/search;;
var encoderJavaPkg = Packages.javax.xml.bind.DatatypeConverter;
var bytes = [];
var encodeString = username + ":" + password;
for (var i = 0; i < encodeString.length; ++i) {
bytes.push(encodeString.charCodeAt(i));
}
var authHeader = "Basic " + encoderJavaPkg.printBase64Binary(bytes);
var result = post(url, stringify({
"tableName": tableName,
"start": 0,
"count": 100,
"query": query
}), {"Authorization": authHeader, "Content-Type":
"application/json"}, "application/json");
print(result.data);
} catch (e) {
log.info(e);
}

[1] - 
https://docs.wso2.com/display/DAS300/Retrieving+All+Records+Matching+the+Given+Search+Query+via+REST+API

As for now to start both server (DAS and DS) I have changed offset
value for DAS as "2" in carbon.xml.I can successfully start both
server simultaneously.It will be very useful if I can get the back-end
URL and server credentials of DAS and get rid of hard-coding those
values.Can anyone please help me and your suggestions mostly
appreciate?
