Re: [Dev] [Integration Cloud] Swagger Support for ESB REST APIs

[Jagath Sisirakumara Ariyarathne]

Hi,

While implementing swagger definition for uri-template based APIs, we have
following problem.

If we have a template like "/view/{symbol}", we need to define "symbol" as
a parameter in swagger definition. According to the swagger spec for
parameters[1], if it is a query or path parameter, then it is required to
have a type (string, number etc) for this parameter. But this information
is not available in existing synapse configurations of APIs. The possible
option is to provide all parameters as "string" as Maheeka mentioned
earlier.

Appreciate any thoughts on this.

[1] - http://swagger.io/specification/#parameterObject

Thanks.

 To get the required information from the Rest API configuration we can
 invoke RestApiAdminServices's getApiByName operation which returns the
 following response [5] for an API created that has the PetStore resources.
 We can identify the methods and uri-template and mappings from this
 response.

 Please let know your thoughts.

 Thanks,
 Maheeka

[Dev] How to get a connection from the carbon datasources

[Chanaka Cooray]

Hi Niranda,

In c5, you can fetch a datasource object using the data source service or
using the jndi context manager. [1]

Thanks,
Chanaka.

Re: [Dev] Invoking a Jaggery api via HttpURLConnection

[Denuwanthi De Silva]

Hi ,

The above get() method returned the response as null.
After several attempts finally got it working with following approach with
the help of Nipuna.
Thanks a lot Nipuna for helping to sort this out.

 var xhr = new XMLHttpRequest();
 xhr.open("GET", url);
 xhr.setRequestHeader("Accept" , "application/json");
 xhr.setRequestHeader("Content-Type" , "application/json");
 xhr.send();
print(xhr.responseText);

Thanks,

Re: [Dev] Duplicate OSGI class inspector for Carbon based products

[Ruwan Abeykoon]

Hi All,
I thought of improving the analysis tool by putting some of the manual
knowledge into the code.

[1] has a tool which can be used to find out why an intermittent class
loading issue occurs. It  provides the offending bundle names.
Please try it out next time when you come across a "intermittent class
loader" issue in Carbon 4.x,  and provide me the feedback on any problems
or improvement you need.

Re: [Dev] How to get a connection from the carbon datasources

[Rajith Vitharana]

Hi Niranda,

Since we use jndi, IMO this approach is also ok. Other than that, you can
also get carbon datasource using Ndatasource component as well. Sample will
be as below

CarbonDataSource cds = dataSourceService.getDataSource("datasourceName");

You will need to get the datasourceService[2] as osgi service.

AFAIR you need to mention datasource name from "name" tag [1]

[1] - 
WSO2_CARBON_DB
[2] - org.wso2.carbon.ndatasource.core.DataSourceService

Thanks,

[Dev] How to get a connection from the carbon datasources

[Niranda Perera]

Hi all,

I want to use a jdbc connection provided by a carbon-datasource.

I found the following blog from Kishanthan [1], which was done in 2013.

it uses the org.wso2.carbon.tomcat.jndi.CarbonJavaURLContextFactory as
follows

Hashtable environment = new Hashtable();
 
environment.put("java.naming.factory.initialoorg.wso2.carbon.tomcat.jndi.CarbonJavaURLContextFactory");
Context initContext = new InitialContext(environment);
Object result = initContext.lookup("jdbc/MyCarbonDataSource");
if (result != null) {
// Do your work here
} else {
System.out.println(“Cannot find MyCarbonDataSource”);
}

My question is, is there a better way of doing this now (a util method may
be?) or is this method still applicable?

Best

 I have tried with 5.1.0 and it is working for me(Tried with v2.0 app).
 The issue because of the mailChimp API version, We created this for api
 v2.0 their we created the federated authenticated User from the email got
 from the response of https://apidocs.mailchimp.com/
 api/2.0/users/profile.php but now it is deprecated. Thank you for
 pointing it. We will update with mailChimp Authenticator for current API
 version.

Re: [Dev] [Architecture] OSGI Service to provision users and roles based on the SAML response.

[Ishara Cooray]

Hi Johann,

I have written a custom OSGI service that can be used to provision users
based on the SAML response which i can contribute since it is reusable in
any application that needs user provision.

Appreciate if you can suggest me suitable repository for this.

Re: [Dev] WSO2 Identity Server Error with MailChimp SSO

[Malaka Silva]

Hi Srikanth,

Thank you for reporting this and we will provide a solution soon.

@Hariprasath - Yes you are correct API 2.0 is deprecated and that does not
mean it's currently unavailable. So we should ideally be changing this to
the latest version.

I managed to reproduce the issue that Srikanth has experienced. The reason
for that is endpoint is dynamic. For example my access token should be
using https://*us14*.api.mailchimp.com/2.0/users/profile, where as you need
to use https://*us12*.api.mailchimp.com/2.0/users/profile for your account.
More details can be found in [1]

Can we provide a fix for this?

I have tried with 5.1.0 and it is working for me(Tried with v2.0 app). The

[Dev] Developer Studio/file connector isFileExist method doesn't allow to save the proxy

[Shazni Nazeer]

Hi,

I'm trying to import fileconnector (version 2.0.2) into developer studio. I
have a proxy in the ESB config project and it uses the fileconnector.

I'm using the isFileExist call to check the whether the file being
requested exist and return File Not Found error to the caller.

The proxy can't be saved in the devloper studio as it doesn't recognize the
is*F*ileExist. But it does recognize is*f*ileExist (Note the lowercase and
uppercase 'f' character). But is*f*ileExist doesn't work in the connector
it self. When called throwing the error [1]

Looks like connector list also shows the method is "isfileExist" but the
internal implementation expects it to be isFileExist.

[1] ERROR - InvokeMediator Sequence template
org.wso2.carbon.connector.fileconnector.isfileExist cannot be found

Re: [Dev] Error when browsing and calculating the number of messages with QueueBrowser

[Shazni Nazeer]

Hi Hasitha,

Please find the created jiira [1]

I used AndesAdminService. I could get the number of messages successfully
by using the getMessageCount with parameter queueName and the pattern as
"queue" method as well as with getQueueByName method.

 HI,

 I have the following code snippet to calculate the number of message in
 the JMS queue in Message Broker.

  ctx = new InitialContext(properties);
  QueueConnectionFactory connectionFactory = 
 (QueueConnectionFactory) ctx.lookup(CF_NAME);
  queueConnection = connectionFactory.createQueueConnection();

  queueSession = queueConnection.createQueueSession(false, 
 QueueSession.AUTO_ACKNOWLEDGE);
  Queue queue = (Queue) ctx.lookup(destinationName);

  QueueBrowser queueBrowser = queueSession.createBrowser(queue);

  queueConnection.start();

  Enumeration e = queueBrowser.getEnumeration();
  int numMsgs = 0;

  while (e.hasMoreElements()) {
  Message message = (Message) e.nextElement();
  numMsgs++;
  }


 When the statement e.nextElement(); is executed it throws an
 exception. The error message I could see in the debug session when
 executing this line is "java.lang.ClassCastException:
 org.wso2.andes.client.message.CloseConsumerMessage cannot be cast to
 org.wso2.andes.client.message.AbstractJMSMessage"

 What's wrong with this snippet? Why is it retrieving
 CloseConsumerMessage?

 Is there any better way to determine the number of messages in the
 queue programmatically?

Re: [Dev] [DEV] NtaskTaskManager Error : No available task nodes for resolving a task location

Hi,

Can you see Member Joined logs as well? AFAIK Member joined logs are the
ones which indicates cluster is correctly  connected.

 Hi,

 That error comes when you start a *non* task node(in this case manager
 node) without starting a task node(worker node). (task node count specified
 in tasks-config.xml). So if you follow below steps, this shouldn't happen.

 1) specify task server count(1) as
 1 in task-config.xml
 2) start worker and then manager. (if worker correctly connects to the
 manger through cluster, this error message shouldn't come)

 Thanks,
