We cannot obtain super tenant's email address via TenantManager as it is
not set.

Hi Godwin,

You can admin username from carbon context when in super-tenant flow.

PrivilegedCarbonContext.getThreadLocalCarbonContext().getUserRealm().getRealmConfiguration()
.getAdminUserName()

Thanks!

[Dev] Authentication and Authorization

[Lipsa Pradhan]

Hello All,

How can I authorize and authenticate different users in WSO2 Enterprise
Integrator?

Actually I want to assign task to different users via a BPEL or a BPMN, but
those users must log in using their credentials and must obtain an access
token to access their tasks.

Is it possible to do so?

Thanks in Advance!

Understood :). I suppose it is sort of a common requirement for all the
messageProcessors. Hence, it is good to have it in CarbonMessage itself.
Let's see what other's opinion as well.

 Hi All,

 In addition to considering all the facts presented above, I also talked
 to each transport developer who actually came up with different types of
 carbon-messages. Based on those discussion I came up with below design.

 Originally, CarbonMessage is designed to carry data between two
 components and I believe it should stay the same. However, it should be
 able carry data relevant to each component. For instance, in JMS case, it
 should be able carry a map for map messages where as in websockets case it
 should be able carry a string.

 Therefore, I thought of creating a CarbonMessage with java generics.
 Then we can extend it accordingly.

 ​

 As you can see above, we can provide a DefaultCarbonMessage
 implementation. However, in HTTP case, we have done some specific
 implementation to optimize the transport. At the moment those logic also
 resides inside the abstract CarbonMessage. With the new design we can
 simply move them to something like ByteCarbonMessage.

 I believe with this design we can have proper abstraction while
 reducing number of redundant carbon messages.

Re: [Dev] Should we refactor CarbonMessage

[Thusitha Thilina Dayaratne]

Hi Shafreen,

IMHO it would be much easier if that functionality os provided by the
messaging layer. Otherwise, each and every MessageProcessors need to
implement that logic. Therefore wouldn't it be nice to implement the
getCopyOfFullMessageBody[1] method from carbon-messaging?

 implementation. Following are few main areas where we can improve its
 functionality.

- At the moment there are too many ways to get the message body
from the CarbonMessage
- getMessageBody()
   - getInputStream() - This is a http specific impl.
   - getMessageDateSource()

 The above 3 methods serve 3 different purposes. This design has been
 done mainly thinking about the HTTP messages. In a message passthrough
 scenario, content is kept in the content queue and accessed as a stream.
 When the message content is accessed within intermediate layer (like
 ballerina), it will be retrieved through messageDataSource.

- There are too many types of CarbonMessages in carbon-messaging
that are only used by a specific transport implementation
   - BinaryCarbonMessage
   - ControlCarbonMessage
   - DefaultCarbonMessage
   - MapCarbonMessage
   - SerializableCarbonMessage
   - StatusCarbonMessage
   - StreamingCarbonMessage
   - TextCarbonMessage


- Most of above CarbonMessages do not adhere to the contract that
is imposed by the CarbonMessage interface.

 I agree on the fact that we need to refactor these different types of
 CarbonMessage implementations. I think what Asitha suggested is a viable
 approach to handle different types of messages.

 Considering these facts, I believe we should refactor CarbonMessage
 before others starting using it in their implementations. Please let us
 know your thoughts as well :)

 +1 for refactoring the carbon message and relevant implementations to
 support non-HTTP use cases. In the meantime, we should support HTTP
 messaging in an efficient manner since that will be the mostly used
 scenario of ballerina.

[Dev] Get Super tenant admin email

[Godwin Shrimal]

Hi All,

We cannot get super tenant information via TenantManager. Below code
returns null, So how can we get the super tenant admin's email address ?

*tenantManager.getTenant(-1234)*

Re: [Dev] [GSoC][Siddhi][CEP]: Siddhi Pattern for Absence of Events

[Gobinath]

Hi Suho,

I have added the test cases to all the cases you have mentioned except the
four listed below because having more than two pattern operands is not
supported by Siddhi. I hope it is okay to skip those test cases. WDYT?


   - every ( (not C and D) and B ) -> A
   - every ((not C and D) or B ) -> A
   - every (B and (not C and D) ) -> A
   - every (B or (not C and D) ) -> A


If there are no more cases to test, may I start with the SEQUENCE?

Gobinath

 Hi,

 I was able to implement /ServiceProviderConfig endpoint compliance test
 as an end to end test [1].

 As discussed I used feign JAX-RS client. I did not directly use Charon
 core objects [1][2] in REST client due to json encoding and decoding
 problem as mentioned by Gayan in the previous mail. Hence I implemented
 separate object object models for this purpose.

 I am hoping to arrange a demo of the currently implemented test and
 also it will be better if I can get your opinions on verifying the
 architecture of the current implementation. Shall we have a quick demo
 session on Thursday (22nd) ?

Re: [Dev] How do I execute a piece of code when a connector is deployed/initialized?

[Rajkumar Rajaratnam]

Thanks Rajjaz.

Firstly, I don't want to use a script mediator, because it has performance
issues with high concurrency. Secondly, I want to execute a piece of code
when the connector is deployed and enabled. I've implemented
ManagedLifecycle and have put my code inside init() and everything works
fine for my usecase. Any issue with this approach?

Thanks,
Raj.

In carbon-datasources, there is a sample [1] in how to use it. I have

Re: [Dev] How to set Database Properties in Carbon Datasources

[Isuru Perera]

Hi,

How do I set database properties in latest carbon-datasources?
https://github.com/wso2/carbon-datasources

As mentioned below, Metrics component needs database properties to work
with Oracle database.

Re: [Dev] Fixing the cache mediator

[Riyafa Abdul Hameed]

Dear all,

I came up with the following configurations for the cache mediator rewrite:

>  [scope=(per-host | per-mediator)] collector=(true | false)
> [maxMessageSize="in-bytes"] HTTPMethodToCache = (GET | POST)]>
>
>   
>
> (mediator)+
>
>   ?
>
>   
>
> 
>

As I have mentioned in the requirements doc[1], the only reason we are
allowing responses to POST messages to be cached is because POST is the
only method used in SOAP implementations. Now having looked at the
implementation details further I understand that it is possible to identify
whether a request is soap or not without having it externally configured.
So my question is whether the configuration "HTTPMethodToCache" is actually
required because it can be internally processed whether request is SOAP or
REST and then cache accordingly.

Isn't cloning of the message body should be done using some util method at
MessageProcessor level ?

 Hi Shafreen and Asitha,
 In the first place, they were introduced after a long discussion in
 WebSocket scenarios. This was because when the WebSocket messages are
 arrived to transport level we already knew what kind of message it is.
 Eg: Text, Binary, Control, Status

 So I made sense to create the same type of carbon message in the
 transport. Then carbon message types were used to identify the scenarios we
 had to address in the application layer.
 Eg: If the carbon message is an instance of TextCarbonMessage we know
 what to do in the first place. Also converting text into byte buffer in the
 transport and then converting it again into text in the application layer
 doesn't make sense.

 Because of that, those message types were introduced. IMO while we
 reduce the no. of carbon message types we might need to keep some of the
 types because it will affect the performance.
 Also, we can always override the methods in default carbon message if
 in order to work with default scenarios.

 WDYT?

 Thanks,
 Irunika

 Hi,

 thanks for the hints and it works adding a log4j.xml into /resources
 but log4j.properties seems to get ignored. Maybe I have some typo 
 somewhere.

Re: [Dev] How to correlate message?

[Melodias]

Hi,

I was try it and that doesn't work. InSequence and outSequence has different
ID: 
IN = urn:uuid:9472d761-0148-4b4d-9fd1-80d426ed9f15
OUT = urn:uuid:d7fc77ec-2bb8-4508-9dfc-358f2de625cc

Re: [Dev] Get started with WSO2 Enterprise Integrator

[Ushani Balasooriya]

Hi Adel,

Please see my answers in Blue for your errors. Please note we recommend you
to send your issues via dev  mail list.


** failure installing the EI :

Can you please confirm whether you have picked the correct EI to install?
You can download it from here [1]

[1] http://wso2.com/integration/?src=sidebar#download

Once you download it, please extract the zip file and go to
wso2ei-6.1.1\bin and run the integrator.bat file. When you double click it
should run if the privileges are set to run it as administrator. Otherwise
you can run as Administrator when you right click on it.

**I have then  downloaded the developer studio from the site
https://docs.wso2.com/display/DVS380/Installation#
Installation-Quickinstallation

and extracted the zip file , but I received the attached list of failure

This is a known limitation in Windows due to the max path limit. Please
configure as it is recommended by microsoft.

***Start Eclipse by double-clicking the Eclipse icon in .*

*You can now access the Developer Studio features
.""*

*however ,The Eclipse does not start *

*Do you recommend any action?*

This seems to be an issue in dev studio 3.8.0. I will report an issue on
this. But you can start it when you right click on exe and "Run As
Administrator".

**message when I double clicked the eclipse icon
Can't start Eclipse - Java was started but returned exit code=13

Can you confirm whether you have downloaded the correct eclipse zip? If
your machine is 64 bits, you have to download the 64 bits zip. If the
machine is 32 bits, you have to download the 32 bit zip. You can download
the correct pack from here [2]

Re: [Dev] How to correlate message?

[Sudharma Subasinghe]

Hi,

Can you try

org.apache.axis2.context.MessageContext a2mc = ((Axis2MessageContext)
synCtx).getAxis2MessageContext();
a2mc.getMessageID();

inside your custom mediator class to obtain the ID?

[Dev] How to correlate message?

[Melodias]

Hi devs,

How I can correlate message?
To correlate IN and OUT message i can set properties with uniq string, but
when i get fault message from the endpoint, then properties is null.
Is there some special ID in message context which I can get by using class
mediator?
