[Dev] Cannot append third context url to startup log

[Malintha Adikari]

Hi,

We have 3 jaggery apps in PC and we want to show each app context URL in
startup log. We can add context URLs up to two apps but 3rd app context URL
is not appearing in the log. I got to know that this is a known issue. Do
we have fix/workaround for this issue ? Is there any public jira to track
the issue ?

Regards,
Malintha

​Right, we might not need to consider standard Docker based deployment in
this project. The reason is that production deployments would most likely
use a container cluster manager.

​Ideally we should have a configuration management system in place to
manage this. It's an overhead to work with multiple VM images.

Re: [Dev] Passing values to the Xpath 2.0 function - fn:avg

[Sohani Weerasinghe]

Hi Shafreen,

I have used [1] in testing the functions, since there is no proper
reference to get a list of functions supported by the Saxon 9.4 HE. Based
on this, can we confirm that the mentioned functions in the above thread
are not supported in HE? (so that we can conclude with the functions we are
supporting in ESB)

[Dev] [C5][CAAS]Getting Invalid user credential When trying to invoke MB through CAAS

[Sajini De Silva]

Hi,

We  have implemented Authentication and Authorization module for MB using
CAAS. When trying to invoke MB through a JMS client I'm getting the
exception in [1]. I have populated the sample data to the user store using
the script in [2]. I'm using username "admin" and password "admin" to
invoke this.

Any idea about this?

Re: [Dev] Integration tests are failing due to NoClassDefFoundError

We have seen this happening when there are multiple different versions of
the same bundle. When webapps uses classes from both these bundles,
class-space violations occur. The error is shown as a java.lang.
NoClassDefFoundError.

Re: [Dev] Passing values to the Xpath 2.0 function - fn:avg

[Shafreen Anfar]

Hi Sohanai,

[+ Asanthi]

We are using Saxon: HE (Home Edition) for XAPTH 2 functions. AFAIK, we
don't select functionality to support so anything supported by library
should already be there, which means it's likely HE edition does not
contain function you're looking for. Please have a look at [1].

Re: [Dev] [IoTS] Failed to connect to the MQTT topic again after disconnect for a while in 1.0.0 alpha

[云展智创]

Ayyoob,

Could you tell me which piece of code in the Raspberry Agent store the client 
information of the device type?

And if I create my new device plugin with "cdmf-devicetype-archetype”, does the 
result codebase will include my device type client information in the agent 
codes? 

Thanks.

Re: [Dev] [GSOC 16] Initial Project Progress

[Osura Rathnayake]

Hi Mentors,

This is the progress so far.

I have created a template, using which you can deploy 3 VMs, manager node,
worker node and a DB. This template can be used in any azure subscription,
you only have to do a template deployment using that template. You have to
pass the relevant VM images at the time of deployment so for that I have
created 5 VM images,

   1. WSO2 AS as manager
   2. WSO2 AS as worker
   3. WSO2 ESB as manager
   4. WSO2 ESB as worker
   5. DB

These VM images are in my azure storage account so that prior to the
deployment, they have to be copied to the storage account of the customer.
Each VM image is approx 30 GB in size. Once you copied the images, you can
start the deployment using the template.

I think it'd better if you have a look at these VM images to check if they
are up to the standard.

Thanks,

 Correction: we need to check if Azure side supports the level of
 metering that is required. As per the information we have up to now, Azure
 has some billing information for the usage, in which we cannot drill down
 and get fine grained information.

 From the R'n D point of view, lets prioritize the following:

1. automating the distributed deployment for few products (AS and
APIM, etc.)
2. Check the possibility of using WSO2 Puppet modules to create the
VM.

Re: [Dev] [IoTS] Failed to connect to the MQTT topic again after disconnect for a while in 1.0.0 alpha

[Ayyoob Hamza]

Hi Jason,

Device does not require a username/password to refresh the token rather it
requires a client Id and client secret[1]. For our sample use cases we can
either create a clientId and client secret per device or per device type.
In the raspberry pi example the client information will be embedded in the
script. Therefore the access token for device can renewed with the client
information and refresh token.

Hi Ayyoob,

Thanks. I am testing to change the AccessTokenDefaultValidityPeriod to 84600 
seconds (about one day). I want to confirm with you whether my understanding of 
the following configuration attributes is correct.

 is used when user login in the 
application and get the client_id and client_secret, the application need to 
request for Refresh token and Access token in 300 seconds.

 is used for setting up the validity period 
for device agent access token. After 3600 seconds, the device agent CAN NOT 
access IoTS with the old Access token.

 is used for setting up the validity 
period for user access token from UI.

 is used for setting up the validity period for 
Refresh token. That’s means, after 84600 seconds, users need to login again to 
get the new refresh token. But how does the device get the new Refresh token as 
it can not login with username/password and the old refresh token is expired?

=


300


3600


3600

84600

 Hi Nathiesha,

 Nothing wrong with both poms and yeah, pom1.xml will break the build.
 However, I think there's a proper solution to this.
 Take a fork of the developer-studio-kernel repo, add your plugin to
 plugins folder. Keep working on that repo afterwards. This way, after
 finalizing the development, you can directly send a pull request to kernel
 repo from your fork.
 Yes, we use the qualifier in versions, in addition to major, minor and
 patch version components.

 As we discussed during previous meeting, you can now start working on
 moving email and jira publishing logic to a web app and expose a single
 rest API for to invoke them. So, eclipse plugin will call to this rest
 service and only a single publisher will be implemented in the plugin. In
 this way, we can get rid of asking users to register on our jira and asking
 them to enter their gmail credentials - both which are most likely ignored
 by users. We will create a bot jira user and email account and keep those
 credentials within the web app it self - and only ask users about their
 contact information (name, email - in case we need to get back - and
 company) when sending the error report.

 BTW, we can have another review on this Friday. Please propose a time
 which fits for you.

 Thanks,

Hi Imesh,

I am not trying access container in K8S, this problem was while running

 Mac uses docker-machine (OSX specific util) to create virtual hosts
 where it runs docker daemon, so its a bit different than Unix where daemon
 runs directly on host. The IP address of deployed container is not directly
 accessible, you need either create forwarding or go through
 docker-machine's IP address. There were bunch of other small changes that I
 had to do to make the test framework work across both Mac and Unix. Now
 that its done, I am working on deployment.

Re: [Dev] [IoTS] Failed to connect to the MQTT topic again after disconnect for a while in 1.0.0 alpha

[Ayyoob Hamza]

Hi Jason,

This happens when the OAuth token is expired for the device. In the IoTS
alpha we have not implemented the renewing the token with refresh token
part, however this has been implemented in the master. One way of having a
continuous connection for the samples in alpha pack would be to increase
the expiration time in identity.xml (repository/conf/identity/identity.xml).

Thanks,
Ayyoob

[Dev] Shindig feature to get tenantDomain, Hostname and Port within a gadget

[Nisala Nanayakkara]

Hi,

Please note that we have added another shindig feature in order to provide
ability to get tenant domain, hostname and port within a gadget. You can
get the tenant domain by requiring identity feature and hostname, port by
requiring server feature as below.

*To get tenant domain*

Require identity feature - 
Then,
var tenantDomain;

wso2.gadgets.identity.getTenantDomain(function(tenantDomain){
this.tenantDomain = tenantDomain;
});

*To get hostname and port*

Require identity feature - 
Then,
var hostname;
wso2.gadgets.server.getTenantDomain(function(hostname){
this.hostname = hostname;
});

var port;

wso2.gadgets.server.getTenantDomain("{protocol}",function(port){
this.port = port;
});

Please note that you have to give appropriate protocol as "http" or "https"
in order to get relevant port.

Thanks,
Nisala

Hi Malaka,

There is another method "readResponseHTTPS" , we may need to modify that

Shall we do the improvement?

 Hi Silva,

 I sent all information about improvement by email before...

 Did you mean..
 create issue in wso2 jira?

 Code change is about 6 line.
 I think this is so simple change..

 What should I do..?

  sent before ===
 Hi Silva.

 This is about Pull request.
 https://github.com/wso2-extensions/esb-integration-base/pull/3

 In other language in UTF-8 like ko_KR.UTF-8, one char is not 4 byte.

 So, split response stream by 1024 byte may cause split one character..

 For example assume that '한글's bit is '010100110111'  and it is located
 on 1024th byte.

 Then, current code will split it into xxx~xxx01010011 and
 0111xxx~xxx.
 And then it will be casted to string by new String(byte[]).
 In this case '한글' will be converted to similarly '한�'.

 I improved this case by read response stream by BufferedReader and char
 array.

 Please check the code, I commited.

 Sincerely.

Re: [Dev] Disabling INFO logs per page rendering

[Sinthuja Ragendran]

Hi Rasika,

As discussed in offline, this improvement is helpful in the standalone
setup for the developer, and hence for the moment I'll merge your change.
But finally we need to provide the log4j.properties in the application
level to really address this issue, but due to time limitations let's go
with your fix now. I have created a JIRA to track this requirement. [1]

[1] https://wso2.org/jira/browse/JAGGERY-426

Thanks,
Sinthuja.

Re: [Dev] Is it possible to use both "Return Generated Keys" and Batch Requests options in DSS 3.5.0?

[Madhawa Gunasekara]

Hi Samith,

At the moment, we don't support returning results for a batch request
operations. because we have to aggregate the result and send them all.
therefore you won't able to get a batch request operation when there is a
result in particular operation's queries.
that's why you won't be able to see the batch operation when you enable
return generated key option.

Thanks,
Madhawa

Re: [Dev] Disabling INFO logs per page rendering

[Dilan Udara Ariyaratne]

Hi Rasika,

Based on the offline chat we had, now I am quite clear on your
implementation and yes, this solves the fundamental development problem
that I had.

For ex: If a developer wants to just focus his debugging on a certain
function that resides on a particular jaggery file, with this
implementation,
he can simply set the log level of that specific file to DEBUG and the
global log level of the entire application to ERROR.

Since this specific log level for the file, defined in server's log4j
properties is not overridden by jaggery.conf global log level setting,
only the debug logs of the specifically mentioned file will be printed in
addition to any error logs of any other file.

Thus, +1 for the improvement.

But, as Sinthuja mentioned, this improvement would be much cleaner if we
can bring these settings configurable within the Jaggery app itself.

Thanks,
Dilan.

Re: [Dev] Passing values to the Xpath 2.0 function - fn:avg

[Sohani Weerasinghe]

Hi ESB Team,

Please find the summary of issues encountered while testing the XPath 2.0
functions at [1] ( referred [2] & [3] for syntax) and really appreciate
your input on this


*1. "Invalid XPath Syntax" occurs when saving the synapse configuration in
management console*

This error occurs for below functions:

   - avg- fn:avg((1,2,3,4,5))
   - codepoints-to-string - fn:codepoints-to-string((97, 32, 98, 32, 99)))
   - distinct-values - fn:distinct-values( ('a', 'b', 'a') ) -This is
   supported when passing the value as an xml payload
   - id - //book/section/secRef/fn:id(@refs)
   - idref - //book/idref('language')/string(.)
   - index-of - fn:index-of( (4, 5, 6, 4), 4)
   - max- fn:max((2,3,5))
   - min - fn:min((2,3,5))
   - remove - fn:remove( ('a', 'b', 'c'), 2)
   - reverse - fn:reverse((1, 2, 3, 4, 5))  -This is supported when passing
   the value as an xml payload
   - string-join - string-join( ('a', 'b', 'c'), '')
   - subsequence - fn:subsequence(('a', 'b', 'c', 'd', 'e'), 3)


*2. Issues in using error() function*

According to https://www.w3.org/TR/xpath-functions-30/#ERRFOER ,
calling the function with empty parameters should give an unidentified
error. But when invoking the service it gives below exception

Is this accepted?

, it seems this is an XSLT function, is that the reason for getting the

 Dear Silva.

 Thank you for read this mail.

 I'm writing to inquire about github contribution..

 I'm testing wso2 esb's functionalites.

 While.. I found a little improvement.

 So I recently created pull request to
 wso2-extensions/esb-integration-base.

 But.. I think no one see this request.

 How  I can resolve this problem?

 I want this improvement could be applied next release.

 I look forward to hearing from you.

 Sincerely.
 from Daekyung Kim.

[Dev] Is it possible to use both "Return Generated Keys" and Batch Requests options in DSS 3.5.0?

[Samith Dassanayake]

Hi All,

Is it possible to use both "Return Generated Keys" and Batch Requests
options in DSS 3.5.0?
For an example I have a query(addFlightQuery) which inserts a record to  a
table. If I don't enable the  "Return Generated Keys"  options as in [1], I
can see both "_post_addflightquery" and "_post_addflightquery_batch_req"
operations. But if I enable it as in [2], it shows only the
"_post_addflightquery" operation. Is it possible to get both
"_post_addflightquery" and "_post_addflightquery_batch_req"  operations
while enabling the "Return Generated Keys"  options

[1]

   
  com.mysql.jdbc.Driver
  jdbc:mysql://localhost:3306/json_array
  root
  root
  1
  10
  SELECT 1
   
   
  insert into flights (flight_no, number_of_cases, created_by,
description, trips) values
(:flight_no,:number_of_cases,:created_by,:description,:trips)
  
  
  
  
  
   
   
  
 
 
 
 
 
  
   


[2]

Re: [Dev] How to add a collection with registry REST API?

[Bhathiya Jayasekara]

I could get it working by sending *-H "Content-Type:
application/atomcoll+xml" *instead of Media-Type.
Docs are incorrect, please fix them.

Thanks,
Bhathiya

[Dev] How to add a collection with registry REST API?

[Bhathiya Jayasekara]

Hi all,

I followed [1] to create a collection with below curl command. I'm using IS
5.1.0 with resource.war from greg.

*> curl -v -k -X PUT -H "Authorization: Basic YWRtaW46YWRtaW4=" -H
"Media-Type: application/atomcoll+xml" -H "Content-Type:

Re: [Dev] [GSoC 2016]Proposal 03: [ML]Visual(Deep) Neural Network Builder -Project Progress

[Lakini Senanayaka]

Hi,

This is the meeting minute for today's GSoC project review meeting.

Upul reviewed the current progress of the project, "(Deep) Neural Network
Builder for WSO2 Machine Learner".
Below mentioned are the decisions made and the new tasks allocated at the
meeting.

Assigned action items:
-Making the UI more user-friendly.
Ex: Physical lines of connections between layers should follow the
movements of the layers.
-Train the feed forward network for MNIST dataset.
-Testing the accuracy of the neural network model for different
optimization and updater algorithms.
-Handling Exceptions.
-Trying to show graphs related to the model, along with the accuracy of
the model in the output.
-Start writing documentation.
-Showing a demo for the ML team.

Decisions made:

 -Higher priority should be given in implementing feed-forward network
than RNN.
 -Upul will provide me necessary instructions on the way to access the
dataset which is inserted through the WSO2 ML console as NN builder UI
needs to access that dataset and use as the training dataset.

Thank you.

Re: [Dev] [IOTS] Failed to get realtime data from IoTS in 1.0.0 alpha

[云展智创]

Ruwan,

Yes, you are right. Thank you very much.

And if you have time, please help to give me some suggestions for question in 
another mail:
-
MAIL: [Dev] [IoTS] Failed to connect to the MQTT topic again after disconnect 
for a while in 1.0.0 alpha

I downloaded a raspberry pi agent from IoTS 1.0.0 alpha, ran the raspberry pi 
agent and uploaded the temperature data successfully. But after I disconnected 
the agent for a while, the MQTT connection could not be setup again. I kill the 
RaspberryAgent process directly. I don’t know if this is the cause of the 
problem.

Can anyone help me for this? Thanks.

 Dear Silva.

 Thank you for read this mail.

 I'm writing to inquire about github contribution..

 I'm testing wso2 esb's functionalites.

 While.. I found a little improvement.

 So I recently created pull request to
 wso2-extensions/esb-integration-base.

 But.. I think no one see this request.

 How  I can resolve this problem?

 I want this improvement could be applied next release.

 I look forward to hearing from you.

 Sincerely.
 from Daekyung Kim.

Re: [Dev] [IOTS] Failed to get realtime data from IoTS in 1.0.0 alpha

[Ruwan Yatawara]

Hi Json,

This is most likely due to the fact that you are accessing the devicemgt
app via a 'localhost' url. Please replace the host section of your
devicemgt app url, with the ip address, and you will be able to see the
statistics.

Please let us know if this fixes the issue you are facing.

Dear Silva.

Thank you for read this mail.

I'm writing to inquire about github contribution..

I'm testing wso2 esb's functionalites.

While.. I found a little improvement.

So I recently created pull request to wso2-extensions/esb-integration-base.

But.. I think no one see this request.

How  I can resolve this problem?

I want this improvement could be applied next release.

I look forward to hearing from you.

Sincerely.
from Daekyung Kim.

Re: [Dev] Installing Features to Carbon Server

[Eranda Rajapakshe]

Hi Lakshani,

Thanks a lot, I was able to install it with "WSO2 Carbon - Tasks Feature".

One more thing, I found that in some situations several features are
bundled together for a single feature. For an example I want to
install "Application
Management Server Feature", but it is bundled with "Application Management
UI Feature" and packaged as "Application Management Feature" [3]. Is there
anyway I can install only the "Application Management Server Feature"
(without the UI Feature) to the Carbon server?

[3].
https://github.com/wso2/carbon-commons/blob/master/features/application-mgt/org.wso2.carbon.application.mgt.feature/pom.xml

Thanks,

Re: [Dev] [APIM] [EMM] Adding multiple scopes to a single API resource endpoint

[Sam Sivayogam]

Hi Milan,

In APIM scopes are there to give access controls based on user roles. A
scope can contain multiple user roles so if you want to block multiple
roles add those roles to a* single scope *and assign to the particular
resource. IMO there is no need to create multiple scopes with different
roles and assigning it to the same resource, when you can already create a
scope with multiple roles.

Thanks,
Sam

 when i build carbon-ml by adding samoa dependencies, it seems to be maven

 need to give local maven repo for the dependency. My extension seperately
 working fine, so there is no problem wihat the local dependencies outside
 carbon-ml. So can you please help me with this.thank you.

Re: [Dev] [APIM] [EMM] Adding multiple scopes to a single API resource endpoint

[Milan Perera]

Hi all,

While going through the code I found that URITemplate class has an
attribute to store multiple scopes.

package org.wso2.carbon.apimgt.api.model;


public class URITemplate implements Serializable {
*...*
private Scope scope;
private List scopes = new ArrayList();

Can we use this scopes attribute to do the $subject?

 Hi Kavith,

 I tried creating the pom.xml by referring to the Developer Studio
 plugin projects in git hub. Following the same structure as in the github
 plugin projects. I came up with this, pom1.xml.

 However since my project is still not under those parent projects as in
 github, I created another pom2.xml as follows, by removing the parent tag,
 by adding p2 repositaries and tycho plugin. After fixing couple of errors,
 I could successfully build the project using pom2.xml.

 Can you please have a look at the two pom.xml files and tell me if they
 seem to be OK or if there are any issues in them? If that is OK, I can move
 to the next milestone of the project.

 Furthermore I changed the Bundle-Version in the project manifest to
 4.2.0.qualifier, because the plugin projects in git hub under Developer
 studio seem to have that version. I hope that is OK.

 Thanks for the article on osgi services. I will go through it.

 Thanks and regards

 Nathiesha

Hi all,

Is $subject possible?
I noticed that $subject capability is limited in UI.

Re: [Dev] Installing Features to Carbon Server

[Lakshani Gamage]

Hi Eranda,

You can install "WSO2 Carbon - Tasks Feature" as
org.wso2.carbon.ntask.core.feature is bundled with
org.wso2.carbon.ntask.feature [2].
You can install that feature using any version of "Tasks" in below image.

Thanks,
Lakshani.

Re: [Dev] Fwd: GSOC2016: [ML][CEP] [SAMOA]Predictive analytic with online data for WSO2 Machine Learner-Samoa Integration

[Mahesh Dananjaya]

Hi all,
samoa is in my local repository and dependencies works fine with all other
extensions that add samoa 0.4.0-incubator dependencies. But only when i
build carbon-ml, it gives priority for the remote repository for looking
samoa. SO any help with this to give priority for local m2 repo before
carbon-ml building is looking for the remote one. I am getting the error
because of this. maven option -U also not seems to be working here. any
help please.

[ERROR] Failed to execute goal on project
org.wso2.carbon.ml.siddhi.extension: Could not resolve dependencies for
project 
org.wso2.carbon.ml:org.wso2.carbon.ml.siddhi.extension:bundle:1.1.2-SNAPSHOT:
The following artifacts could not be resolved:
org.apache.samoa:samoa-api:jar:0.4.0-incubating,
org.apache.samoa:samoa-local:jar:0.4.0-incubating: Could not find artifact
org.apache.samoa:samoa-api:jar:0.4.0-incubating in wso2-nexus (
http://maven.wso2.org/nexus/content/groups/wso2-public/)

Since samoa will be used for future work, is it possible to add that in the
relevant wso2 repo. Because there are still no samoa 0.4.0-incubator maven
repo. only 0.3.0. we cannot continue our work with the 0.3.0 since it is
outdated.

thank you.
regards,
Mahesh.

 I think this is OK. I assume this is much easier. Let's do this and
 check the performance.
