Hi Lakshitha,

Also make sure that the stream is persisted, otherwise the data will not be
persisted in DAS. Please refer to [1]

Re: [Dev] Publish data set in DAS

2016-03-01 Thread Lakshitha Warnakulasuriya

Thanx Ayyoob.

I'm using ESB(4.8.1) and DAS(3.0.0) for publish data from ESB to DAS.

For the testing, I want to publish string from ESB to DAS. I followed below
steps for do that. But it's not working.

   1. First I create a soap service for return a simple string like 'Hello
   World'.
   2. Create BAM Profile in ESB.
   3. Create a *Pass Through Proxy* in ESB using this soap wsdl.
   4. Create *BAM Mediator* using above proxy service.
   5. After invoke the service, there is a new stream created in DAS.
   6. Create *soap event receiver* for the above stream.
   7. Check Data Explore in DAS.

Any help can be really appreciated.

Thanks and Regards,
Lakshitha.

[Dev] Drag and Drop not being supported by default in GMF gen code

2016-03-01 Thread Awanthika Senarath

Hi,

The issue of  datamapper operators not being drag, drop able, the issue is
that GMF auto gen code by default does not support drag drop ability.
Instead it support select and drop.

This could be fixed as follows according to [1].

In the gen code the DataMapperPaletteFactory class contains an internal
class *NodeToolEntry*  which by default extends ToolEntry class. It needs
to extend PaletteToolEntry class for the tool items to have drag and drop
capability.

I have done the changes and added a class comment "Generated NOT" to the
modified class.

 Hi All,

 When representing attributes in avro schema,  according to [1] the
 suggested approach is to use @ as a prefix.

 Since avro name should start with [A-Za-z] and subsequently contain
 only  [A-Za-z0-9_], shall we represent it as below (adding ATT as a prefix)

 "name" : "*ATT*_gender"

 Thanks Nuwan for the response.

 When generating the avro schema by adding elements to the tree
 view, user can specify the namespace (xml namespace) with the prefix, 
 so
 that when generating the the avro schema we can map the namespace to 
 doc
 and prefix to the namespace in avro.

 Yes that's mapping is fine , somehow we need to show at least prefix in
 the tree view otherwise user experience won't be nice since user have to
 check it explicitly while doing the mapping

Re: [Dev] Issue in representing avro records with multiple namespaces

2016-03-01 Thread Sohani Weerasinghe

Hi All,

When representing attributes in avro schema,  according to [1] the
suggested approach is to use @ as a prefix.

Since avro name should start with [A-Za-z] and subsequently contain only
 [A-Za-z0-9_], shall we represent it as below (adding ATT as a prefix)

"name" : "*ATT*_gender"

 Thanks Nuwan for the response.

 When generating the avro schema by adding elements to the tree view,
 user can specify the namespace (xml namespace) with the prefix, so that
 when generating the the avro schema we can map the namespace to doc and
 prefix to the namespace in avro.

Hi Thanuja,

Always follow the Puppetlabs language style guide [1] when writing puppet
manifests.
Even the above code is working, the best practice to surround the variables
with curly braces.

Re: [Dev] No such method when loading third party jar in eclipse

2016-03-01 Thread Awanthika Senarath

I have fixed this by moving the datamapper specific libraries from the
kernel libraries plugin into the datamapper plugin. This will give us the
flexibility to change and add different libraries required for datamapper
independent of kernel releases,

We can release the composite zip for the ESB plugin milestone including
this kernel update to the library feature. This fix also contains the fix
for cache mediator jar required by ESB diagram.

update is org.wso2.developerstudio.kernel.core.feature_4.0.0.201603020233.

This is available in the builder machine P2

Hi Pubudu,

Can you come up with the use cases that you are planning to add on top of
HTTP GW. Also, come up with a design of the existing GW and how the LB
related features will be implemented on the GW. These things will be
critical in order to proceed with the project.

Thanks,

Hi Minudika,

Which options should be available for the user to get decisions? For

I think that depends on the implementation. As you've mentioned, # of
samples, would definitely has to be a user-input. Other than that, sample
size, algorithm to be used, its hyper-parameters, aggregation criteria (if
there are multiple ways of aggregating), etc might have to be taken from
the user.

Similarly, for stacking, we might have to get from user: the # of models,
algorithm for each model, hyper-parameters for each model, algorithm for
aggregation, and etc..

Supun

First you can evaluate  existing  loadbalancers (ex Nginx , HA ) and look
in to main features related to HTTP loadbalancing such as  Load balancing
methods (roundrobin, iphash, leastconnected) , session persistence,  ..etc.
Try to identify how those concepts works within those and come up with a
set of features that needs to be implemented.

thanks

Re: [Dev] [APIM] Adding new API store themes for tenants via admin-dashboard

2016-03-01 Thread Shenavi de Mel

Hi Jo,

Just another concern. Is there a particular reason why the deployment of
web fonts with the theme is also not allowed. If user wants to change the
default web fonts is that going to be of any harm to the product and it's
functions?

 AVRO name should start with [A-Za-z] and subsequently contain only  
 [A-Za-z0-9_].
 So we can not pass name with namespace prefix.

  We should add above xml namespace prefix as the namespace of AVRO
 record. Then two elements can be differentiated.
 For Eg:

 {
   "type" : "record",
   "name" : "root",
   "fields" : [ {
 "type" : "record",
 "name" : "tableRecord",
* "doc" : "http://www.w3.org/TR/html4/
 ",*
 "namespace" : "N1",
 "fields" : [ {
   "name" : "name",
   "type" : [ "null", "string" ],
   "doc" : "http://www.w3.org/TR/html4/;
   } , {
   "name" : "width",
   "type" : [ "null", "int" ],
   "doc" : "http://www.w3.org/TR/html4/;
   },{
   "name" :

 Hi All,

 If we consider an XML which has multiple namespaces as below ,

 
 http://www.w3.org/TR/html4/;>
   Asian Coffee Table
   74
   129
 
 http://www.w3schools.com/furniture;>
   African Coffee Table
   80
   120
 
 

 The avro schema should be as follows ,

 {
   "type" : "record",
   "name" : "root",
   "fields" : [ {
 "type" : "record",
 "name" : "tableRecord",
* "doc" : "http://www.w3.org/TR/html4/
 ",*
 "namespace" : "http://www.w3.org/TR/html4/;
 "fields" : [ {
   "name" : "name",
   "type" : [ "null", "string" ]
   "doc" : "http://www.w3.org/TR/html4/;
   } , {
   "name" : "width",
   "type" : [ "null", "int" ]
   },{
   "name" : "length",
   "type" : [ "null", "int" ]
   }]
 }, {
 "type" : "record",
 "name" : "tableRecord",
   *  "doc" : "http://www.w3schools.com/furniture
 ",*
 "namespace" : "http://www.w3schools.com/furniture;
 "fields" : [ {
   "name" : "name",
   "type" : [ "null", "string" ]
   } , {
   "name" : "width",
   "type" : [ "null", "int" ]
   },{
   "name" : "length",
   "type" : [ "null", "int" ]
   }]
 } ]
 }

 When representing this using the Visual DataMapper Editor, in order to
 differentiate the two records, we can add a namespace prefix to the name of
 the record as shown below.


 But when generating the Avro Schema, if we pass this value as the name
 of the node it  throws *org.apache.avro.SchemaParseException: Illegal
 character in: y:tableRecord.*

>>>

 So, if we use only the name (tableRecord, by removing the prefix) to
 create the avro schema, how are we going to differentiate the records
 separately when generating the mapping config?

Re: [Dev] XML to json array in ESB

2016-03-01 Thread Chanaka Fernando

Hi Shazni,

There should some information in the xml message to tell that it is an
array when there is only one element. Otherwise, JSON builder cannot figure
out it is an array. You can use the following in the xml message to
instruct the consumers about array.

**



user1

Yes that's mapping is fine , somehow we need to show at least prefix in the
tree view otherwise user experience won't be nice since user have to check
it explicitly while doing the mapping

Re: [Dev] [ML][GSOC] Ensemble learning for WSO2 ML

2016-03-01 Thread Minudika Malshan

Hi,

Please help me to be clarified on this.
Apart from the implementation of those ensemble methods at the back end,
we're supposed to develop some UI features.
Which options should be available for the user to get decisions? For
example, if the user is going to use the bagging method, the number of
samples can be pre-defined by the user.

Minudika

[Dev] [GSoC] Proposal 8: HTTP Load balancer on top of WSO2 Gateway

2016-03-01 Thread Pubudu Fernando

Hi,

I'm a 3rd year Computer Engineering undergraduate student from University
of Moratuwa and I am interested in contributing to proposal 8, developing a
HTTP load balancer on top of Gateway for GSoC. I am a bit familiar with
load balancing concepts and WSO2 Gateway and I have configured and used
Ngnix as a load balancer when configuring WSO2 server clusters. And I also
did some background reading ([1], [2]) in order to gain a better
understanding of concepts behind the construction of a load balancer.

I would be grateful if you can advise me (topics and libraries that I
should look up etc), regarding how to proceed with this project. Also, can
you please elaborate a bit more about the requirements? Which load
balancing algorithms do you expect to be implemented in this project?

[Dev] XML to json array in ESB

2016-03-01 Thread Shazni Nazir

Hi,

Say for example used a proxy below [1] to convert an xml to json.

[1]

http://ws.apache.org/ns/synapse; name="XmlToJSON"
transports="https,http" statistics="disable" trace="disable"
startOnLoad="true">









using a payload like [2] returns a response like [3] with a json array.

[2]

user1
user2


[3]

{
  "users": {
"user": [
  "user1",
  "user2"
]
  }
}

using a payload like [4] returns a response like [5] without square
brackets, since there's only one element.

[4]

user1


[5]

{
  "users": {
"user": "user1"
  }
}

But I need to get this user1 in an array even if there's only one
element in the array. I can however use a payload factory with a
filter mediator like below to achieve this. Wondering if there's any
other simple way to achieve without this? Your input is appreciated.

[6]

Re: [Dev] [DAS] Retrieving sorted data from queries to DAS

2016-03-01 Thread Udara Rathnayake

If it's a temporary table, you should be able to do the sorting within the
spark query.
So no need to worry about sorting at the client side.

Re: [Dev] Calling DSS REST resources using JSON payloads

2016-03-01 Thread Gokul Balakrishnan

Hi Madhawa,

Thanks, I was using an input format like:

{
"timeFrom" : "2001-01-01 11:44:52",
"timeTo": "2010-06-01 11:44:52"
}

but it only worked once I'd incorporated the resource name as well, similar
to:

{
  "getFilteredNotices": {
"timeFrom" : "2001-01-01 11:44:52",
"timeTo": "2010-06-01 11:44:52"
  }
}

Please note that as per the documentation, we should add "_post" to the
resource name, which did *not* work (there was an NPE). Could you please do
the needful to correct the documentation as required?

Thanks,

Re: [Dev] Issue in representing avro records with multiple namespaces

2016-03-01 Thread Sohani Weerasinghe

Thanks Nuwan for the response.

When generating the avro schema by adding elements to the tree view, user
can specify the namespace (xml namespace) with the prefix, so that when
generating the the avro schema we can map the namespace to doc and prefix
to the namespace in avro.

Thanks,
Sohani

AVRO name should start with [A-Za-z] and subsequently contain only
[A-Za-z0-9_].

 We should add above xml namespace prefix as the namespace of AVRO record.
Then two elements can be differentiated.
For Eg:

{
  "type" : "record",
  "name" : "root",
  "fields" : [ {
"type" : "record",
"name" : "tableRecord",
   * "doc" : "http://www.w3.org/TR/html4/
",*
"namespace" : "N1",
"fields" : [ {
  "name" : "name",
  "type" : [ "null", "string" ],
  "doc" : "http://www.w3.org/TR/html4/;
  } , {
  "name" : "width",
  "type" : [ "null", "int" ],
  "doc" : "http://www.w3.org/TR/html4/;
  },{
  "name" : "length",
  "type" : [ "null", "int" ],
  "doc" : "http://www.w3.org/TR/html4/;
  }]
}, {
"type" : "record",
"name" : "tableRecord",
  *  "doc" : "http://www.w3schools.com/furniture
",*
"namespace" : "N2",
"fields" : [ {
  "name" : "name",
  "type" : [ "null", "string" ],
  *"doc" : "http://www.w3schools.com/furniture
"*
  } , {
  "name" : "width",
  "type" : [ "null", "int" ]
  *"doc" : "http://www.w3schools.com/furniture
"*
  },{
  "name" : "length",
  "type" : [ "null", "int" ],
  *"doc" : "http://www.w3schools.com/furniture
"*
  }]
} ]
}

Then the full names of the two tableRecords will be N1.tableRecord and
N2.tableRecord and AVRO can differentiate these two fields.

Mapping configuration does not need to be aware of the namespaces as long
as they can be differentiate in the diagram. Output from the mapping will
look into the output schema and will build the output message with desired
namespaces.

[Dev] Issue in representing avro records with multiple namespaces

2016-03-01 Thread Sohani Weerasinghe

Hi All,

If we consider an XML which has multiple namespaces as below ,


http://www.w3.org/TR/html4/;>
  Asian Coffee Table
  74
  129

http://www.w3schools.com/furniture;>
  African Coffee Table
  80
  120



The avro schema should be as follows ,

{
  "type" : "record",
  "name" : "root",
  "fields" : [ {
"type" : "record",
"name" : "tableRecord",
   * "doc" : "http://www.w3.org/TR/html4/
",*
"namespace" : "http://www.w3.org/TR/html4/;
"fields" : [ {
  "name" : "name",
  "type" : [ "null", "string" ]
  "doc" : "http://www.w3.org/TR/html4/;
  } , {
  "name" : "width",
  "type" : [ "null", "int" ]
  },{
  "name" : "length",
  "type" : [ "null", "int" ]
  }]
}, {
"type" : "record",
"name" : "tableRecord",
  *  "doc" : "http://www.w3schools.com/furniture
",*
"namespace" : "http://www.w3schools.com/furniture;
"fields" : [ {
  "name" : "name",
  "type" : [ "null", "string" ]
  } , {
  "name" : "width",
  "type" : [ "null", "int" ]
  },{
  "name" : "length",
  "type" : [ "null", "int" ]
  }]
} ]
}

When representing this using the Visual DataMapper Editor, in order to
differentiate the two records, we can add a namespace prefix to the name of
the record as shown below.


But when generating the Avro Schema, if we pass this value as the name of
the node it  throws *org.apache.avro.SchemaParseException: Illegal
character in: y:tableRecord.*

So, if we use only the name (tableRecord, by removing the prefix) to create
the avro schema, how are we going to differentiate the records separately
when generating the mapping config?

eg: If we are to map a field in  y:tableRecord with a field
in y:tableRecord etc. How can we differentiate this?

This usecase of having multiple namespaces can be displayed graphically in
the Design view by appending a namespace prefix, but it seems this will
have issues in generating the avro schema and the mapping config.

Your suggestions are highly appreciated.

Thanks,
Sohani

Re: [Dev] [Puppet-Modules] Puppet Error: cwd must be a fully qualified path

2016-03-01 Thread Thanuja Uruththirakodeeswaran

Thanks Manula !!!

The error is because of the syntax error that we need to use *" " *for if
the value has variable. Here the cwd attribute value has carbon_home
variable. Following code will resolve the above puppet error:

exec { "Applying secure vault":
  user   => $user,
  path   =>
'/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin',
  cwd=> "$carbon_home/bin",
  command=> "sh ciphertool.sh -Dconfigure
-Dpassword=$key_store_password",
  logoutput  => 'on_failure'
}

Thanks.

[Dev] [Puppet-Modules] Puppet Error: cwd must be a fully qualified path

2016-03-01 Thread Thanuja Uruththirakodeeswaran

Hi All,

I'm trying to change the cipher tool execution command at [1] so that first
I need to go inside the $carbon_home/bin directory and then trying to
execute the cipher tool with the following code snippet (We need to do this
for carbon kernel 4.2.0 based products as discussed in [2]) :

exec { "Applying secure vault":
  user   => $user,
  path   =>
'/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin',
  cwd=> '$carbon_home/bin',
  command=> 'sh ciphertool.sh -Dconfigure
-Dpassword=$key_store_password',
  logoutput  => 'on_failure'
}

But the above exec fails with below error:

==> brs.dev.wso2.org: Error: Parameter cwd failed on Exec[Applying secure
vault]: cwd must be a fully qualified path at
/tmp/vagrant-puppet/modules-3737bfc9b53e65d741f2b9b350c2e2ca/wso2base/manifests/apply_secure_vault.pp:28

Re: [Dev] [ESB500] JMS Inbound Endpoint behavior with Session Acknowledgement

2016-03-01 Thread Malaka Silva

Hi Dilshani,

Flow is very simple except following exceptions. Take message -> execute
mediation (sequence) -> ack the broker.

If you want to rollback set SET_ROLLBACK_ONLY mc property to true in fault
sequence.

Also in mediation flow non-blocking mediator should be used. eg:- callout
mediator not send mediator.

 Hi,

 I need to query MySQL database with Carbon 5 based product and I added
 the mysql-connector-java-5.1.35.jar [1]  file to the osgi/droppings
 directory. Since the jar file is already an osgi bundle I copied it
 directly to osgi/droppings folder.

 But when I load the class as below it gives the
 java.lang.ClassNotFoundException.

 Class.forName("com.mysql.jdbc.Driver");

 Is there any missing step I followed which can cause this error?

Re: [Dev] Error on loading external OSGI bundles with Carbon 5

2016-03-01 Thread Anupama Pathirage

Hi,

Thanks for the suggestions.

I already tried with followings. May be something is wrong in the way I
specified them.

1) import the com.mysql.jdbc pacakage

[5.1.35, 5.1.38)
com.mysql.jdbc.*;version="${mysql.import.version.range}"

2) Adding dynamic import

*

I have attached my pom.xml file herewith.

Re: [Dev] Error on loading external OSGI bundles with Carbon 5

2016-03-01 Thread Aruna Karunarathna

Hi Anupama,

Since you are doing a class.forName();, you have to do dynamic import
package.

Can you try adding that to your pom.xml?

Regards,
Aruna

[Dev] [ESB500] JMS Inbound Endpoint behavior with Session Acknowledgement

2016-03-01 Thread Dilshani Subasinghe

Hi Malaka,

In ESB, JMS Inbound endpoint can configure Acknowledgement Type with
"transport.jms.SessionAcknowledgement". When it set as "Client_Acknowledge"
, What will be the behavior of ESB ? Does it behave like normal JMS Client
which enabled "Client_Acknowledgement" ?

I'm using separate JMS Client with "Client_Acknowledge" mode and using it
to test JMSX Delivery Count. But ESB Inbound endpoint doesn't behave like
particular JMS Client (With "Client_Acknowledge" mode).

Can you explain ESB behavior within the particular scenario ?

Thank you.

Hi Anupama,

Are you importing the com.mysql.jdbc package inside your bundle which uses
mysql?

[Dev] Error on loading external OSGI bundles with Carbon 5

2016-03-01 Thread Anupama Pathirage

Hi,

I need to query MySQL database with Carbon 5 based product and I added the
mysql-connector-java-5.1.35.jar [1]  file to the osgi/droppings directory.
Since the jar file is already an osgi bundle I copied it directly to
osgi/droppings folder.

But when I load the class as below it gives the
java.lang.ClassNotFoundException.

Class.forName("com.mysql.jdbc.Driver");

Is there any missing step I followed which can cause this error?

 Might be better to rename wso2am-docker-1.0.0.zip

 I have now fixed above:

Re: [Dev] Packaging the Kubernetes Artifacts

2016-03-01 Thread Isuru Haththotuwa

Hi Vishanth,

Few comments:

   - Move the property kubernetes.artifacts.version to root pom
   - No need to define profiles, common plugins (assembly) and repositories
   in each pom, they can be declared in the root pom and inherited.

 Hi Vishanth,

 The plan is to have the base image in Docker Public registry so that
 anyone can pull it whenever they want. However, IMO we should also ship the
 common image artifacts, in case the users need to modify the Base image.

 We can additionally link the common Dockerfile with the Docker registry
 [1].
