[Dev] Running unit test form IDE error - Input file does not exist: maven-resources

[Manuranga Perera]

I can't run unit tests form Intellij 16 in repositories that depends on C5
parent. It gives an error [1]. But it works if I modify the parent pom. As
far as I have tested this change have no other effect. I have sent it as a
PR [2]

Does this issue happen to anyone else?

 Hi Damith,

 You can set update the existing schema using the REST APIs directly as
 mentioned here [1]. The table name cannot be removed from DAS.

Re: [Dev] [Architecture] [REST APIs][Analytics] GET request with a payload

[Ayoma Wijethunga]

Agreed. Then again, if user needs to include more columns than he needs to
exclude we can introduce something like below and use the most suitable
depending on the length.

service?*include*=column1,column2*- only include columns specified by
user*
service?*exclude*=column1,column2   *- include all columns, excluding what
is provided by user*

Then again, there are even lower level limitations such as InnoDB limit on
maximum 1000 columns [2].

If we really have such as use case where this list can grow more than 2000
characters, maybe it is best to use POST only for such abnormal scenarios.

 Hi,

 It is true that using GET request with a payload is not the best
 option. Even though it is not strictly prohibited in specs, it can be
 confusing [1]. REST architecture is very open about how we use HTTP
 methods, but thinking in terms of REST architecture, I do not think using
 POST is also the correct approach here [2] (maybe it is just the personal
 preference).

 Let me summaries few examples on how others have addressed the same
 requirement with GET requests.

 Facebook Graph API is using "field" query parameter for this [3]. For
 example :

 Following Graph API call 
 *https://graph.facebook.com/bgolub?fields=id,name,picture
> * will only
> return the id, name, and picture in Ben's profile

 SharePoint syntax is not very eye candy [4][5], but it goes like :


> http://server/siteurl/_vti_bin/listdata.svc/DocumentsOne?$select=MyDocumentType,Title,Id&$expand=MyDocumentType

 YouTube API has the same in below form [6] :

 Example 1: Retrieve number of items in feed, index of

> fields=openSearch:totalResults,openSearch:startIndex,entry

 LinkedIn has the same [7]


> https://api.linkedin.com/v1/people-search:(people:(id,first-name,last-name,positions:(id,title,summary,start-date,end-date,is-current,company:(id,name,type,size,industry,ticker))
>

 IMO Facebook Graph API has the cleanest mechanism.

 I believe that if we use a similar format we will not have to introduce
 new resource paths. Instead we'll be able to provide all the columns,
 unless user specifically request limited set of fields with a query
 parameter. WDYT?

Re: [Dev] GSoC '16 - Proposal 16: Contact Development Team feature in DevStudio

[Chanuka Wijayakoon]

Hello everyone,

I went through the DevStudio kernel and have a few questions. I'd be ever
so grateful for your answers.

1. The DeveloperStudioLog class doesn't include any control scheme to limit
reporting multiple cases of the same error in short time periods.
Reporting all cases seems like a nuisance, especially if it's an intended
error.
Would limiting such successive reports cause any harm? One way would be to
pause/ stop reporting the same error after, say, 10 close occurrences.

2. Should the error report be fully automated and not interact with the
developer at all?
It seems better to allow the developer to attach a message along with the
report. That way the internal devs can get contextual info as well.

3.  Developers would be interested in getting feedback for what they report
and want to track the progress on issues. This could be implemented as an
opt-in feature, along with anonymization.
Thoughts?

Best regards

Re: [Dev] Issue in representing an array which contains non identical elements

[Sohani Weerasinghe]

Hi All,

If we consider the generated json schema is a valid one, then when
generating the tree from that schema we have to treat "urn:sObjects" as two
arrays. i.e before creating the tree nodes we have to iterate through the
items section and then check for the objects inside that and then create
two tree nodes ( two arrays) containing the elements.

- urn:sObjects (array)
 - AccountId
 - FirstName
 - LastName

- urn:sObjects (array)
 - Name

When we are saving the editor we read the tree and then serialize the
values to a file. In that case, we treat these nodes and two arrays. As a
result the created json schema will be different that the initial schema.

How are we going to handle this situation?

Thanks,
Sohani

Re: [Dev] [Architecture] [REST APIs][Analytics] GET request with a payload

[Udara Liyanage]

Hi,

IMO by using POST to do a GET  we are violating REST principals and may
confuse users. You can see a query type API in [1] used by StackOverflow
API. According to [2], it seems  about 2000 characters are allowed  most
browsers which is a pretty large number where a normal GET request is
highly unlikely to exceed in practical situation regardless of the number
of fields exist.

Re: [Dev] DAS Lucene query AllowLeadingWildcard

[Gimantha Bandara]

Hi Damith,

If the "roles" field contains comma separated values, you can simply search
for the specific role using the following query

"roles : role1"


Lucene has an analysis process which takes place before indexing. So the
field values will be tokenized into terms(Text fields are split removing
special characters) , stop words.. etc. In your case, the whole string
"role1, role2, role3" will be tokenized into "role1", "role2" and "role3".
So you can perform a usual search query as I mentioned above.

Re: [Dev] DAS - How to change the schema of a table

Hi Damith,

you can set the schema again from Spark script also. you can write a query
llike this

create temporary table  using CarbonAnalytics options (tableName
"", schema "", mergeSchema "false");

Re: [Dev] [Architecture] [REST APIs][Analytics] GET request with a payload

[Gimantha Bandara]

Thank you for your suggestions.
We cannot exactly say that the number of columns/fields user will need. It
depends on how many fields a table has and how many the user want to get
from that table. So the url length might exceed. If so, we will have to go
with a new method with POST as it seems the only option.

 Hi all,


 We have a REST API in DAS to retrieve records in a specific table. It
 supports GET method with the following url format.

 /analytics/tables/{tableName}/{from}/{to}/{start}/{count}

 Sending a GET request to above url will give the records between given
 "from", "to" time range starting from index "start" with  "count"  page
 size.

 Now we need to change the API, so that the user can define the record
 columns/fields he wants. Current API will return the records with all the
 values/columns. To do that, we can allow the user to define the columns he
 needs, in the payload. But it seems that having a payload with a GET is not
 the convention/the best practice.

 POST can be used to send the column names as a payload, but here we are
 not making any updates to {tableName} resource. We will be just retrieving
 records using a POST. So it also seems not the convention/the best 
 practice.

 The only solution I can think of is, having a different resource path
 to get the records with only specified fields/columns. Are there any other
 solutions?

 Thanks,
 Gimantha

[Dev] DAS Lucene query AllowLeadingWildcard

[Damith Wickramasinghe]

Hi all,

I have a column which contains roles as a comma separated string. eg:-
role1,role2,role3

I need to find records which matches to specific role. As I checked theres
no String contains function. But there is wildcard support[1]. To be able
to work for my usecase wildcard should be of type *role1*. But leading wild
cards are not supported. But as per the [2] Lucene 2.1, they can be enabled
by calling QueryParser.setAllowLeadingWildcard( true ). May I know whether
there is a configuration in DAS to enable this. Also even this can be
achieved I think this will be an expensive operation. If so is there a best
way to achieve this? eg:-custom UDF

Re: [Dev] DAS - How to change the schema of a table

Hi Damith,

You can set update the existing schema using the REST APIs directly as
mentioned here [1]. The table name cannot be removed from DAS.

[Dev] [CDMF] [IOT] IOT SDK for creating Device Agents-GSoC2016

[Shabir Mohamed]

Hi Harshani,

*What is expected off this project is as follows - *

Like you have correctly understood when a new device needs to be added to
the WSO2 IoT Server, a new Device Plugin has to be created. This plugin
goes into the IoTServer. When the IoT Server is started it will recognise
all the available "Device Plugins" and register the device-type specific to
the Device Plugin as a new device in the IoT Server.

So if you want a "connected-cup" installed into the server you will have to
write a "Device Plugin" for the connected-cup and install it into the
IoTServer.

*The Device-Plugin (specific to a device-type) has several components to
it: *

   - Plugin component that gets registered to the CDMF via OSGI
   - Device Management & Controlling APIs written as JAX-RS webapps
   - UI Components as to how the device-type is listed
   - Analytics Component
   - *Device Agent*
   - etc...

Whilst all the above components of the plugin are Java code that goes into
the server the "*Device Agent*" is some code written to be
*burned/installed/uploaded* into the device hardware in order for it to
communicate with the IoT-Server using the proper API's that you have
written in the other components. This agent can be in different languages
according to the device.

Ex:
*Arduino - Arduino C (an abstraction on top of C/C++)*
*RaspberryPi - Python, Java, C*
*ESP8266  - Lua*

So what we basically expect off this project is to specifically focus on
making the experience of writing the "*Device Agent*", of the plugin easy
for an end user. So the SDK should ideally have implementations of the
complex bits of communicating to the server (using languages such as C,
C++, java, python) which can be utilised by the Device-Agent writer.

Hope this helps.

Regards

[Dev] Need More elaboration on max_open_connections

[Vanjikumaran Sivajothy]

Hi Devs,

Currently the expiation for max_open_connections the explain available in
[1], However, it does not explain about the client side consequences. IMO,
doc should explain about it too.

[Dev] DAS - How to change the schema of a table

[Damith Wickramasinghe]

Hi all,

I have already created a table with some columns using spark queries and
inserted some data. But I need to add another column to it. Is there a way
to directly achieve this ? Or do I have to drop the table and reinitialize
it ? Also I cannot seems to find a way to remove the table also ? I have
purged all data in said table.

Regards,
Damith.

Yes, you are correct.

Actually, w don't need to implement anything on top of the DL4J library in
order to support Spark. It is already available in DL4J.

Thanks,

 Hallo!

 I am Misgana, hailing from Freiburg, Germany and I am interested in
 working with you on the Ensemble methods . I have already implemented
 Stacking in python(code available in github/zemoel) and compared it to
 other ensemble methods such as Ensemble Selection on AUC performance
 measures. The comparison also included using above mentioned methods as
 part of an automated machine learning platform(Autosklearn).

 I am currently working on my proposal and would be grateful for your

 Hi Asantha,

 I've added the latest proposal you've sent to google docs in [1]. As
 Chamila suggested, can you list down the methods that you expose in the API
 (public methods in the userstore manager) in the proposal so that it is
 easy to understand the functionality of the userstore manager. Also it is
 better to submit the proposal to google now and update later if any
 modification is needed.

 Hi Asantha,

 Thanks for sending your proposal. It seems to be in good shape, but
 I would like to suggest few more improvements.

1.  You have mentioned you are implementing Custom User Store
Manager by extending JDBCUserStoreManager. But actually you have to 
 extend
AbstractUserStoreManager. I think you have done this correctly in 
 the code
you sent previously. Please correct this.
2. I think by custom user store manager, you have meant mongoDB
user store manager you are planning to implement, in most places. 
 Its
better to mention specifically as MongoDBUserStoreManager than 
 saying
custom user store manager.
3. You have mentioned about "Implement a proper encryption
mechanism to overcome the security hauls in custom User store 
 Manager.".

Re: [Dev] Regarding the Location and Time-based Device Policy Enforcement Project for Gsoc2016

[Kasun Dananjaya Delgolla]

Hi Sameera,

Please find the documentation link[1] for policy management. You can
carefully study the current behavior of the policy management feature and
think of a unique way of solving the problem "Enforcing policies based on
users location and a given time frame". Take all the points that I've
described in my first mail and start building your proposal. Good luck!

Re: [Dev] GSoC '16 - Proposal 16: Contact Development Team feature in DevStudio

[Awanthika Senarath]

Hello Chanuka,

What we expect is something similar to eclipse mars implementation.

The latest released developer studio is on Eclipse Luna, and the next
release would be on Eclipse Mars which would be release within this
quarter.You can checkout the Developer Studio kernel code and get a basic
understanding on the code level.

You can go ahead and start creating your proposal.

Re: [Dev] GSoc 2016-Proposal 16

[Awanthika Senarath]

Hi Nathiesha,

All you proposed ideas seems good.

You can add all the ideas you have as optional features in your proposal.
We can evaluate the applicability once the proposal is submitted.

As for the user side errors network availability and resource blocking it
may not be required to be reported.

Re: [Dev] GSOC 2016 - Project 21 : Review Proposal

[Tharindu Edirisinghe]

Hi Asantha,

I've done some minor modifications to the doc. For the methods exposed
through the API, can you add them in a table to improve the readability.
(Chamila has suggested this already as a comment in the doc). You can have
some columns for Method Name, Return type, parameters, description.

Once you do this, submit it to google because the deadline is tomorrow for
proposal submission.

Thanks,
TharinduE

Re: [Dev] Fwd: [GSoC 16'] Proposal 20: [IS] SCIM 2.0 Support to WSO2 Identity Server

[Manujith Pallewatte]

Hi all,

Thank you very much for the comments, I revised and changed as much as
possible.
About the confusion by Entitlement Engine I wanted to refer to the
EntitlementEngine.java class in src since it has the main entry points to
the service
But it is really a confusing detail and i changed it to Identity Server
instead
Also i added a few illustrations to make some points clear
Please give me feedback on the revised proposal

 Thank to Omindu I was able to use SoapUI to simulate a request for now,

[Sameera Wickramasekara]

Hi,

I have successfully built the WSO2 EMM from source. i have understood that
the deliverables are time and location based policy enforcement. how should
i start to implement a custom policy/ change a policy  in the EMM ? can you
point me to a tutorial of some sort.
And i hope i will be able to complete my proposal before the deadline with
your guidence

Re: [Dev] Issue in representing an array which contains non identical elements

[Susinda Perera]

Online xsd generators[1] generate xsd as one object having all four
elements as child elements of urn:sObjects, without considering xsi:type.

The xsi:type attribute is used to identify derived complex types[1]. In
this example we have 2  objects which have different
xsi:types. (i.e one does not have a xsi:type but other one
having xsi:type="urn1:Contact") Therefore these two are different
objects even though it has same name.
However by looking at the given xml we can not say that it's xsd would have
 array or single element because in this example we have only
one object from each. Shall we add and object of  and check?

Re: [Dev] [Architecture] [REST APIs][Analytics] GET request with a payload

[Lahiru Sandaruwan]

Yes, if it is possible to put the columns names in the url as Ayoma
mentioned, we must use that(First i thought it is a complex payload you
want to send).

Unless there are limitations, like column list doesn't exceed the url
length limits, we should use GET.

Thanks.

Re: [Dev] [Architecture] [REST APIs][Analytics] GET request with a payload

[Ayoma Wijethunga]

Hi,

It is true that using GET request with a payload is not the best option.
Even though it is not strictly prohibited in specs, it can be confusing
[1]. REST architecture is very open about how we use HTTP methods, but
thinking in terms of REST architecture, I do not think using POST is also
the correct approach here [2] (maybe it is just the personal preference).

Let me summaries few examples on how others have addressed the same
requirement with GET requests.

Facebook Graph API is using "field" query parameter for this [3]. For
example :

Following Graph API call
*https://graph.facebook.com/bgolub?fields=id,name,picture
> * will only
> return the id, name, and picture in Ben's profile
>

SharePoint syntax is not very eye candy [4][5], but it goes like :

http://server/siteurl/_vti_bin/listdata.svc/DocumentsOne?$select=MyDocumentType,Title,Id&$expand=MyDocumentType
>

YouTube API has the same in below form [6] :

Example 1: Retrieve number of items in feed, index of
> first item in result set, and all entries in the feed:
> fields=openSearch:totalResults,openSearch:startIndex,entry
>

LinkedIn has the same [7]

https://api.linkedin.com/v1/people-search:(people:(id,first-name,last-name,positions:(id,title,summary,start-date,end-date,is-current,company:(id,name,type,size,industry,ticker))
>

IMO Facebook Graph API has the cleanest mechanism.

I believe that if we use a similar format we will not have to introduce new
resource paths. Instead we'll be able to provide all the columns, unless
user specifically request limited set of fields with a query parameter.
WDYT?

 So if time permits, I would like to suggest you to add some details
 about what are the APIs and functions you are going to expose after
 developing this new user store manager, if you have already decided on
 them. Since you may have went through the codes of existing user store
 managers, you may already have an idea about what are the functions you
 need to exposed to outside. So if can add at least few functions you are
 going to expose with some details, it would make your proposal more
 attractive. Also I would like to suggest you to add link of github repo
 where you have started development. Also if you have written any blogs
 related to the project, mongoDB, etc. please mention them also in your
 proposal.

 Also I see some formatting issues and some dates has got repeated in
 your timeline, hope you will correct the when submitting proposal at GSoC
 site.

 Cheers!

Re: [Dev] [Architecture] [REST APIs][Analytics] GET request with a payload

[Lahiru Sandaruwan]

Hi,

I think using a POST with a body, for retrieving information is fine
considering the requirement. GET with body is not recommended.

Thanks.

[Dev] [REST APIs][Analytics] GET request with a payload

[Gimantha Bandara]

Hi all,


We have a REST API in DAS to retrieve records in a specific table. It
supports GET method with the following url format.

/analytics/tables/{tableName}/{from}/{to}/{start}/{count}

Sending a GET request to above url will give the records between given
"from", "to" time range starting from index "start" with  "count"  page
size.

Now we need to change the API, so that the user can define the record
columns/fields he wants. Current API will return the records with all the
values/columns. To do that, we can allow the user to define the columns he
needs, in the payload. But it seems that having a payload with a GET is not
the convention/the best practice.

POST can be used to send the column names as a payload, but here we are not
making any updates to {tableName} resource. We will be just retrieving
records using a POST. So it also seems not the convention/the best practice.

The only solution I can think of is, having a different resource path to
get the records with only specified fields/columns. Are there any other
solutions?

Thanks,
Gimantha

Re: [Dev] Issue in representing an array which contains non identical elements

[Awanthika Senarath]

Even though these arrays are identical, AFAIS they may occur independent,

as in we may have 5 of the first array with the three items and 3 of the
other array which is completely unrelated to the first array,


In that case is it okey to represent them as a single array?

according to [1] it seems like the xsi:type attribute is not just any
attribute but something similar to a key word in XML. in that case IMO it
is not correct to represent these two arrays as a merged array instance.

We need to consider xsi:type attribute as a keyword. I dont know how viable
this is though.

Re: [Dev] Issue in representing an array which contains non identical elements

[Chanaka Fernando]

Hi Sohani,

I think the representation which is in the json is correct. If you look at
this json message using a tool like [1], You can view that you have 2
elements in the array (of type sObjects). Within those elements, you can
have different elements. Adding all 4 elements under the same array is not
correct AFAIU.

Re: [Dev] [GSOC2016]Proposal 4: [ML] Ensemble Methods Support for WSO2 Machine Learner

[Supun Sethunga]

Hi Misgana,

I went through your proposal. Overall it looks good. Here are a few
comments I would like to point out:

   - Its better to have some sort of an architecture diagram, explaining
   your solution in a higher level.
   - In the timeline, better to break down the "Week 1­3 (May 23 ­ June 20,
   2016)" into three sub-levels, and allocate timeslots for each of the three
   methods (Stacking, Boosting and Bagging) separately. That would make it
   easy for you to work on those methods separately, as well as to track the
   progress.
   - In the timeline, can you double check the "week" numbers..? for eg; in
   [*Week 1­-3 (May 23 ­ June 20, 2016*], I guess it should be "*Week 1-4*"
   (there are four weeks in the mentioned duration). Similarly, check the
   others too.

Please share us the draft proposal once you fix those.

Thanks,
Supun

[Dev] Issue in representing an array which contains non identical elements

[Sohani Weerasinghe]

Hi All,

If we consider the below xml, "urn:sObjects" is an array which contains
elements which are not identical.

First array contains AccountId, FirstName, LastName and the other array
contains Name.

 http://www.w3.org/2001/XMLSchema-instance";>
 
   
   001D00HRzKD
   Jane
   Doe


   Acme Rockets, Inc.

 

The generated json schema would be as follows

{
   "$Schema":"http://json-schema.org/draft-04/schema#";,
   "title":"urn:create",
   "id":"http://jsonschema.net";,
   "type":"object",
   "properties":{
  "urn:create":{
 "id":"http://jsonschema.net/urn:create";,
 "type":"object",
 "properties":{
"urn:sObjects":{
   "id":"http://jsonschema.net/urn:create/urn:sObjects";,
   "type":"array",
   "items":[
  {
 "id":"http://jsonschema.net/urn:create/urn:sObjects/0";,
 "type":"object",
 "properties":{
"AccountId":{
   "id":"
http://jsonschema.net/urn:create/urn:sObjects/0/AccountId";,
   "type":"string"
},
"@type":{
   "id":"
http://jsonschema.net/urn:create/urn:sObjects/0/@type";,
   "type":"string"
},
"FirstName":{
   "id":"
http://jsonschema.net/urn:create/urn:sObjects/0/FirstName";,
   "type":"string"
},
"LastName":{
   "id":"

   "type":"string"
}
 }
  },

 "type":"object",
 "properties":{
"@type":{
   "id":"
http://jsonschema.net/urn:create/urn:sObjects/0/@type";,
   "type":"string"
},
"Name":{
   "id":"
http://jsonschema.net/urn:create/urn:sObjects/0/Name";,
   "type":"string"
}
 }
  }
   ]
}
 }
  }
   },
   "namespaces":[
  {
 "prefix":"urn",
 "url":"urn:enterprise.soap.sforce.com"

  },
  {
 "prefix":"urn1",
 "url":"urn:sobject.enterprise.soap.sforce.com"
  }
   ]
}


I am facing an issue in representing this in the tree view. Are we going to
add all 4 elements ( AccountId, FirstName, LastName and Name) under the
array object?

Really appreciate your input on this.

Re: [Dev] [GSOC2016]Proposal 4: [ML] Ensemble Methods Support for WSO2 Machine Learner

[Supun Sethunga]

Hi Deng,

Couple of comments:

   - Can you add sort of an architecture diagram, explaining your solution?
   (which visually explains implementation in a higher level)
   -
   - In the Road map, It makes more sense to mention the starting-date and
   end-date for each of the phases (instead of the duration). Also you can add
   time-slots for other steps (like doing the background research, code
   cleanup,  documenting and etc..) too, to the same timeline.

Rest of the proposal looks good to me. :)

Thanks,
Supun

 Hi Madhuranga,

 I just checkout the master branch and built without any issues.
 May be some compatible issues with maven and jdk versions?

 Thanks

Re: [Dev] [ESB] Can we use sequence + endpoint at the same time within clone mediator ?

[Dilshani Subasinghe]

Hi Malaka,

Thanks for clarification. There was an old test case for $subject and I am
checking validity of that. When I am implementing following sequences, it
doesn't give an exact error. But it also do not send to back end. Is there
any exact reason for that?

PS: Sample test case of above scenario is available at:

Thank you and Regards,

Re: [Dev] Shall we use latest APPM in EMM?

[Lakshman Udayakantha]

Hi All,

After I have merged the APPM latest version and configuration changes from
APPM to EMM and after the above code changes, publisher and store can be
browsed and publish apps without any issue. But app installing on devices
failed because the code which handles that part are moved to an APPM old
branch(which is currently using in EMM) from EMM. So I cherry-picked those
specific commits from that old branch to master branch in APPM. After that
app installing on devices worked without any issue. But product app manager
P2 profile generation failed with below error messages.

 Software being installed: WSO2 Carbon - App Manager WSO2 MDM Feature
1.1.3.SNAPSHOT (org.wso2.carbon.appmgt.mdm.wso2mdm.feature.group
1.1.3.SNAPSHOT)
 Missing requirement: org.wso2.carbon.appmgt.mdm.wso2mdm 1.1.3.SNAPSHOT
(org.wso2.carbon.appmgt.mdm.wso2mdm 1.1.3.SNAPSHOT) requires 'package
org.wso2.carbon.device.mgt.core.app.mgt 0.0.0' but it could not be found

According to the error, It seems like we have to bundle carbon device
features and lot of other features which depend on it with APPM product
which is not actually used in APPM.

According to the offline discussion with PrabathA, DinushaS, RuwanA, It was
proposed to keep the code handled which handled app installing on devices
in APPM as a separate independent feature, but not bundled with APPM
product rather it bundled with EMM product.

Thanks

 Hi Dinusha,

 When user is going to login to store, user will add if does not
 exist, to a table called APM_SUBSCRIBER . This code snippet has 
 removed in
 EMM store (in APPM 1.1.1 version). That's why earlier this problem is 
 not
 raised. Anyway what is the purpose of adding user to the APM_SUBSCRIBER
 table? Note that this table is the only dependant table from APPM to 
 EMM.

 Thanks

[Dev] Fwd: Proposal 18: [ESB] X12 inbound and connector

[Malaka Silva]

Hi Mafrin,

If you are interested in doing this you need to submit the proposal before
deadline. (25th of March). Find some background info about this proposal,

We already have a inbound endpoint to support HL7 that was released with
ESB 4.9.0.

First we need to do some research on X12 and how we incorporate this into
ESB. So if this is going to be a listening inbound and a connector or a
enhancement to existing hl7 transport should be decided on your findings.

So as the first step start researching on X12 and learn on HL7 ESB inbound.

This does look like a bug [1], however, is also due to reaching the limit

them out.

[Dev] Getting "Program too complex: too big jump offset" error in a jaggery file

[Supun Sethunga]

Hi,

I have a jag file containing ~1900 LOC [1]. To that, I added few more
stringify() calls. At one point, the jag app throws the below exception. If
I remove any of the stringify() methods, it works fine. (This error is
thrown for other functions such as well, like array looping or accessing
array elements and etc).

Wonder whether there is a limit of instructions/logics per single jag file?


Appreciate any help/workaround on this.

[Dev] Resources supported by @Context annotation in msf4j

[Himasha Guruge]

Hi All,

Found from [1] that currently the supported object injections are for
HttpStreamHandler,HttpRequest and HttpResponder.

 Are there any plans for this annotation to support injecting Http URI
related details  as well? Since our existing BPMN REST api is using this
annotation to get above information.

 Hi sir,

 This is what we found when we were going through the API.

 Network Security Group (NSG) is the equivalent AWS Security group that
 we could find in azure. And this [1] is the API reference that can be used
 to get information about a particular NSG. There under networkInterfaces.id
 element, we can get a collection of references to Network Interface
 Cards that reference this NSG. And then using that we can get information
 about NICs [2]. There under virtualMachine element, we can get the VM
 associated with that NIC. Can we use this method to identify a group of
 VMs?  or can't we simply assign a tag to set of VM and identify them using
 that tag?

 Yes I think this is good. Can you please prepare a project proposal and

Re: [Dev] Fwd: [GSoC 16'] Proposal 20: [IS] SCIM 2.0 Support to WSO2 Identity Server

[Pushpalanka Jayawardhana]

Hi Manujith,

Added the comments and suggestions. Please have a look and correct.
Please also note that the entitlement engine we have in PDP component is
the Balana engine and there is no seperate entitlelment engine within IS.
IS provides XACML support on top of Balana engine, with other required
functionality for PEP, PAP and PIP.

Thanks,
Pushpalanka

 Hi Manujith,

 There are no cURL commands available as we do not have REST
 implementation as of now.
 In order to get familiar with the code base and development environment
 and to try out the scenario you suggested follow the below steps.

 1 - Try to write a Java client for EntitlementService (SOAP service) [1]

 Please find the relevant service at [1]. This is the service that needs
 to be cosumed in order to get the XACML policy decision from PDP for a
 given XACML request.

 Specific method to call is "public String getDecision(String request)
 throws EntitlementException " giving the XACML request as a String.
 The relevant stub classes can be found at [2] that can be used at client
 side. Try to get client code written for this which can be placed in PEP
 when required. You can further publish a blogpost with this client code
 which can strengthen your proposal further.

 2 - In production scenarioes usually ESB acts as the PEP creating the
 XACML request and calling the PDP via code similar to client code you would

 The article at [3]

Re: [Dev] Urgent: Regarding GSoC 2016

[Sajini De Silva]

Hi Vedang,

Great to hear that you are interested in the project. In current model WSO2
ESB uses JMS transport to connect to IBM MQ which needs some configurations
to be done. You can get basic understanding about this by referring the
link at [1]. However there are some limitations in the current system.
Therefore we prefer to have a native inbound to connect to IBM MQ.

You can start the project by,

   1. Installing IBM MQ 7.5.
   2. Then try to connect to MQ as consumer and producer from a java
   client. Using IBM MQ client.
   3. The next step is to create the consumer as a custom inbound[2][3] and
   the producer as a connector [4] [5]

Also you need to consider the security aspect of these scenarios as well
when you make the proposal. (Enabling mutual SSL)

Also please note that the deadline for proposals will be coming Friday.
Therefore you may need to submit the proposal soon before the deadline.

 Hi Pushpalanka,

 Sorry for spamming the inbox like this, but since I'm already behind
 the schedule I have to get things resolved as fast as possible. Please
 don't mind it.
 One more thing as I finally got to the conclusion, the objective is to
 implement RESTful service to the PDP of IS so that any PEP can access them
 in a RESTful manner? In other words the REST service should be
 implemented to facilitate the information exchange between the PEP and PDP
 Is that correct? please correct me if i'm wrong

That could be a issue. In that case we will special case this claim in the
dashboard and not show it.
@Pushpalanka: please note.

Ideally we should have application specific profile in IS and each
application should decide what claims to show and what not to.

Thanks.

 Hi Dilini,

 Intended use of this feature is only for administrators/users with
 user-mgt previlleges to disable/enable user accounts.
 Therefore a user should not be able to disable own account. We
 discussed to hide this claim from user profile UI by default and move the
 disable/enable click to user list view. This is not done yet though.

 Will get to you after discussing with the team on our stand on this.

 Thanks,
 Pushpalanka.

Re: [Dev] [IS] User's can disable their own accounts

[Dilini Gunatilake]

Hi Johann,

Thanks for the information. You have mentioned that it is highly unlikely
that users are accessing their profiles via the management console. Can you
please clarify whether it is the same for the Dashboard also? Because the
end users can disable their profiles via the dashboard as well.

Thank you.

Dilini

 Hi IS Team,

 When identifying test scenarios for User Account Disability feature in
 IS 520, I noticed that users can disable their own accounts and carry out
 work until the session expires or they log out. But the system will throw
 exceptions for the operations they do in both management console and
 dashboard. eg: change the password

 What should be the ideal behaviour in this scenario? Should the user
 have privileges to disable their own account?

 Thank you,

 Overall looks good to me! Added a few comments, please fix them too.

 Also, can you share a rough timeline too? If you feel like the
 current project goals does not fit into the deadlines, we can revise 
 the
 goals before starting the project, so that it would fit within the 
 timeline.

 BTW, please CC to WSO2 Developers mailing list (dev@wso2.org) for

Hi Sumedha,

Gimantha will implement same for the REST API as well. This will be
available in the DAS-3.0.2-SNAPSHOT pack.

Re: [Dev] [DAS] Is there a way to retrieve selected fields from a given table

[Sumedha Rubasinghe]

Gihan,
Can't we implement the same functionality for REST API?

This will help to prevent maintaining two client logics for REST API &
Admin API.

Hi Ravindi,

When testing same configs with ESB 5.0.0 m2 pack [1], it doesn't give exact
error. You can try out. It may be fixed the issue through new pack.

 Hi Sohani

 I do not think this is a correct representation,
 *"items": [] , *this says id is an empty array, but it is not (in this
 example it has 2, and also it has some value inside id tag, which is string
 in this example. if we say its empty array we loose all these information.
 Therefore i believe it should be something like below.

 *"items": [{*
 * "id":
 "http://jsonschema.net/queryMoreResponse/result/sf:records/0/sf:Id/0

 * "type": "string"*

[Gihan Anuruddha]

There is a parameter that you can specify which column you need for
response.

 Hi Osura/Sahan,

 Please try to do the following first:

1. Create a free Azure account
2. Evaluate virtual machine and container features in Azure. As I
saw container support is very primitive at the moment. We can use K8S on
Azure for container based deployments. In this project will focus on VM
based deployment.
3. Go through the Azure API and see how we can identify a group of
VMs. On AWS we do this by using security groups. We call this group a
cluster.
4. Next try to start a WSO2 product in a VM.
5. Afterwards will try to implement a Carbon Membership Scheme for
Azure using the Azure API and the above grouping feature.
6. Next we need to identify how to use native Azure features for
implementing following:


- Auto healing
   - Autoscaling
   - Dynamic load balancing
   - Multi-tenancy
   - Configuration orchestration
   - Artifact distribution
   - Software update distribution
   - Multi-region/cloud deployments
   - Centralized logging
   - Monitoring
   - Metering


 Thanks

Re: [Dev] [ESB] Error message when adding a datasource

[Jason De Silva]

Hi Ravindi,

I also encountered the issue that you are facing when I tried it out in a
fresh ESB 490 pack, seems like this is a validation error caused at " Name
" field. If you add a name that does not have letter " s " you will succeed
with the test connection and will be able to save it too. I suggest you
better raise a jira so that ESB team can track it.

Jason
