Re: [Dev] [DEV][JAGGERY] Getting Empty JSON when logging(log.info)

 Point taken, logging circular objects is a problem. My concern is that,
logging Java objects details in "JSON string format" is not a good way to
do it. May be we can log details of the Java object without following the
JSON format. Like this,

(class: org.wso2.models.Student, toString: "name: Kamal, age: 25, city:
Colombo")


Thanks.

working with docker hub, we can make it to work with private docker registry

Re: [Dev] Running WSO2 Products on Cloud Foundry

[Chamila De Alwis]

Hi Nanduni,

If we can use the Docker images in CF (Diego), then we will be able to
reuse the existing Dockerfiles in WSO2 Kubernetes Artifacts repository [1].
It will just be the matter of modifying the Heroku (or any other) Docker
build pack to use a private Docker registry.

When the Docker daemon connects to a private Docker registry, it will
record the token in the config file ~/.dockercfg. Is there any possibility
to provide this configuration to BOSH so that it will not prompt for the
authentication during runtime?

Re: [Dev] Running WSO2 Products on Cloud Foundry

[Nanduni Nimalsiri]

Hi Chamila,

Yes we can use custom buildpacks to deploy on Cloud Foundry. I am not
familiar with all WSO2 products, but I suppose that we need to run shell
files in most cases. So we can customize or build our own buildpack to
detect those files.

Diego is a separate approach. It is a new run time that replaces DEA in
Cloud Foundry. With Diego, we can use Docker images to push applications to
Cloud Foundry, But there are some limitations. We need the images to be
available in Docker Hub publicly. But I found that there's something new
called 'Private Docker Registry' in Diego that enables to use private
Docker images where users are prompted for credentials during staging the
app. I was unable to run Diego as it requires administrator privileges to
enable docker support for me.

Also there is a cf-docker buildpack that detects Docker images. It also has
the above mentioned limitations. I am not sure if we can customize that
buildpack to detect private images as well. They say that it is just a
proof of concept.

I have tried to get help from cf-dev mailing lists as well. They suggest
that I need to have administrator privileges to resolve above scenarios.

Best Regards,
Nanduni

Default that uses Warden for its container management. We can try with
heroka buildpack[1] to run the docker images.

Re: [Dev] [DEV][JAGGERY] Getting Empty JSON when logging(log.info)

[Manuranga Perera]

Hi Sajith,
+1 not longing full object. Logging full object might break existing code
that has logs of Java object in other products. If a developer accidentally
logs a circular references it might even crash the server. Logs are for
getting a bit of information for debug or operational purposes, it
shouldn't be heavy or have any side effects.

A log should be something you should be able to put without worrying too
much.

Re: [Dev] Running WSO2 Products on Cloud Foundry

[Chamila De Alwis]

Hi Nanduni,

Wouldn't writing a custom buildpack (for each product) [1] allow us to
deploy a given artifact on CloudFoundry? We'd have to write the detect,
compile, and release scripts separately.

Is there any difference between that approach and using Docker images?

Re: [Dev] Integrating WSO2 IS with Kubernetes

[Nishadi Kirielle]

@Imesh : This configuration has to be done in kube api server. It provides
options to set the authorization mode in 'always allow', 'always deny' or
'ABAC' modes. In using ABAC mode, it provides an option
--authorization-policy-file
  to set the user configured authorization policy. [1]

kube-apiserver --authorization-mode=""
kube-apiserver --authorization-policy-file=""

How do you going to deploy the server in Cloud foundry? Did you use
Buildpack? Also Did you check with Diego in the case of docker?

[Dev] Running WSO2 Products on Cloud Foundry

[Malmee Weerasinghe]

Hi All,
As an initiative for the $subject I have deployed Cloud Foundry with BOSH
Lite, have run some sample applications both in BOSH lite and Pivotal Cloud
Foundry.

BOSH Lite is a pre-built Vagrant box which includes the BOSH Director. BOSH
Lite is used for developing and testing releases locally.

Cloud Foundry is now owned by Pivotal software and Pivotal Cloud Foundry is
a commercial implementation.

I have written two blog posts as an introduction to Cloud Foundry [1] and
Bosh and Bosh Lite in Cloud Foundry [2].

As an approach to the $subject I am deploying tomcat server in Cloud
Foundry and am expecting to replace the deployment with a WSO2 product
(docker).

Your suggestions on this subject are highly appreciated.

Is OpenLDAP[1] not an option? It has a long track record and is the case
when most user scenarios are considered.

[Dev] Integrating WSO2 IS with Kubernetes

[Nishadi Kirielle]

Hi All,

As a initial step to be familiar with Kubernetes, I have set up a
Kubernetes cluster and deployed some sample applications. [1] [2]

In K8s, authorization and authentication happen as two separate steps.
Available authorization implementations are as follows;

   - --authorization-mode=AlwaysDeny
   - --authorization-mode=AlwaysAllow
   - --authorization-mode=ABAC (user configured authorization policy)

Authentication policy basically uses client certificates, tokens or http
basic auth to authenticate users for API calls.

In accessing K8s API, although the provided command line interface is
*kubectl*, in programmatic approach there are several client libraries for
accessing K8s API from several languages. [3]

My initial plan is to connect a LDAP implementation like OpenDS or ApacheDS
with Kubernetes.
Any suggestions are highly appreciated.

Thanks

+1 for this approach. BTW are we planning to write the data from two
streams to the same table?

[Dev] Retrieve Development Support Hours from SalesForce

[Lakmini Chathurika]

Hi All,

I wrote a proxy service to get development support hours from salesforce .
In here I got the data from two tables Line_Item__c  and Opportunity.
Because in salesforce Line_Item__c table keeps the records before January
and Opportunity table keeps the records January onwards.
In the proxy first I wrote a SOQL query to get the data from Line_Item__c
table and published to DAS through the data stream
"SALESFORCE_DATA_STREAM_1".
Then I wrote another SOQL query to get the data from Opportunity table and
published to DAS through the same datastream.

The Proxy is as shown below.


http://ws.apache.org/ns/synapse";
   name="SalesForceProxy"
   transports="https,http"
   statistics="disable"
   trace="disable"
   startOnLoad="true">
   
  
 
 
200
SELECT  LastModifiedDate, Support_Account_ID__c,
Dev_Support_Hours__c FROM
Line_Item__c WHERE Support_Account_ID__c != 'NULL' AND
Support_Account_ID__c != '' AND Support_Account_ID__c
LIKE '%DEV' ORDER BY LastModifiedDate DESC NULLS
FIRST
 
 
 

   
  
 UD_DAS
 SALESFORCE_DATA_STREAM_1
 1.0.1
 



   
   
   


 
  
   

 

  
  
200
SELECT
Development_Support_Account_Key__c,Development_Support_Hours__c,LastModifiedDate
from Opportunity
WHERE Development_Support_Account_Key__c !='NULL' AND
Development_Support_Account_Key__c !=''AND
Development_Support_Account_Key__c
LIKE '%DEV' ORDER BY LastModifiedDate DESC NULLS
FIRST
 
 

 
 

   
  
 UD_DAS
 SALESFORCE_DATA_STREAM_1
 1.0.1
 



   
   
   


 
  
   

 
  
   
   



Is it ok to get data from these two tables like this or are there any
better solutions to do this?
Any suggestions are highly appreciated.

Thanks & Regards.
Lakmini.

It is not something we have done intentionally (missing functionality). We
have to provide that functionality from Netty http transport level.

[Dev] Fwd: Error while creating init for 4.10

[Malaka Silva]

go ahead with script mediator.

@Nadeeshaan - Can you please confirm.

Hi Malaka,

IMHO we can create the salesforce REST connector will support all the ESB
versions. Since there are no difference in performance while we are using
script or property mediator.
Is there any particular reason to create Salesforce REST for 4.10 only by
using property mediator?

I have an issue in use the user defined path to store the values in
registry using property mediator.

This is how i used to store the value in Registry.


Here the value is store in $ctx:uei.var.timeRegistryPath

and

If i using this,



 i got the below error,

Re: [Dev] [ESB] Http Endpoint Template Documentation

[Nisrin Sheriff]

Hi Chathurika,

Looks like this is missing in older versions of ESB docs as well. I checked
in the management consoles of versions 4.8.0, 4.8.1 as well and it seems to
be there.

So I'll check with the ESB team about the version that this was introduced
and add this to the relevant docs.

Will resolve the JIRA once I add the info to the relevant docs.

Thank you

 Hi,

 Those classes you were refering are not MSF4J service classes.
 Therefore, we don't have to consider them with the tool. IMO, since
 Pet-Sore sample is bit complex it's better if you could first work with
 samples other than the Pet-Store to get the tool running.

 Samiyuru

Re: [Dev] MSF4J dependency resolving failure in gen code from swagger codegen

[Samiyuru Senarathne]

Hi,

Structure and the used pattern looks fine. Apart from them,

   - We have to remove NotFoundException from the API and implementation
   since that is not how MSF4J send responses in error cases.
   - We can remove ApiResponseMessage class.
   - Can we fix the formatting of the generated code?
   - Can we remove the unused imports? (IE import java.io.InputStream; in
   StockQuoteApiService)

Best Regards,
Samiyuru

 Hi Samiyuru,

 MSF4J tool generated code build fails with the following errors [1].

 These imports are introduced by the swagger codegen library we are
 using. I am working on changing these imports to the imports that are
 supported by the MSF4J team.

 In going through your petstore sample I could observe the imports [3]
 in the class [2].

 I tried building the petstore sample and it builds fine. Could you
 please let me know what causes the build break in the gen code of the
 swagger codegen library? I have attached the gen code.

[Dev] [MB] Wait until Qpid server starts on port 5672 and then Connection timed out

[Charitha Goonetilleke]

Hi All,

We are using MB features on IoT Server and $subject occur in server startup
time, on Fedora 23 (4.3.4-300.fc23.x86_64), we already test this on ubuntu
and mac os, but no such issue detected. Here is the stack trace of the
error and I already add further few log lines, which is successfully
connected with AMQP on port 5672.
