@CD, is this something we could fix? can we list features in the order of
the indices?

Hi Nirmal,

We will be able to fix this issue.

Thanks Thushan for pointing this out! :)

 Hi all,

 I've been testing the new Deeplearning component with few different
 datasets (mainly leaf dataset) and the leaf dataset seems to be not working
 as expected for an unknown reason.

 However, I tested the Deeplearning component extensively with the leaf
 dataset and identified several potential problems that might be causing the
 poor accuracy.

 1. Need to have higher number of epochs (compared to other datasets) to
 produce a reasonable accuracy.

 2. Too many neurons causing overfitting thereby causing poor accuracy.

 3. Some classes have quite closely related features (Especially the
 latter classes are misclassified often)

 I was able to get an accuracy of 86% with Logistic Regression L-BFGS.
 Which is quite reasonable. But I'm having trouble reaching that accuracy
 with Deeplearning (which should be quite easy). Highest accuracy I reached
 so far is 71.xx%

 So I'm still looking for any definite issues causing the poor accuracy.

 Thank you.

 Hi all,

 After a daunting struggle, I was able to corner the issue with the poor
 accuracy for the specific leaf dataset. The dataset has classes from 1 to
 36. However, there are no classes from 16th - 22nd. i.e. Classes go as
 1,2,..,14,15,23,24,...,35,36

 Then, while converting these class labels to enums in H-2-O (combined
 with the fact that there's very little data for each class) confuses H-2-O
 and causes it to *assign different enum values for the same classes in
 different datasets*. Which manifest itself as a poor accuracy.

 I suspect that there's a mismatch between the labels provided by
 JavaRDD and enums produced by H-2-O as well. I'm looking into this issue
 right now.

 Thank you

[Dev] [ML] Issue while loading the leaf dataset (misreading classes)

[Thushan Ganegedara]

Hi,

I found the potential cause of the poor accuracy for the leaf dataset. It
seems the data read into ML is wrong.

I have attached the data file as a CSV (classes are in the last column)

However, when I print out the labels of the read data (classes), it looks
something like below. Clearly there aren't this many "3.0" classes and
there should be classes up to 36.0.

Is this caused by a bug?

1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0
1.0 1.0 1.0 12.012.012.012.012.012.0

 Hi All,

 During implementation an issue was raised on using the curl client to
 send messages to the echo server. Therefore in order for the Java echo
 server to be able to accept messages from the curl client I have included a
 JAX- RS web service in between.

 I have attached a diagram showing the updated design for the POC.

 Regards.
 Sabra.

 Hi,

 I found the potential cause of the poor accuracy for the leaf dataset.
 It seems the data read into ML is wrong.

 I have attached the data file as a CSV (classes are in the last column)

 However, when I print out the labels of the read data (classes), it
 looks something like below. Clearly there aren't this many "3.0" classes
 and there should be classes up to 36.0.

 Is this caused by a bug?

 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0

[Dev] at_hash hash size

[Udara Liyanage]

Hi,

The fixing PR of [3] (Access Token hash value is calculated incorrectly)
pick the first 16 bytes as the left most half of the digest. Just for my
curiosity, can we guarantee it is always
16 bytes, or otherwise digest is always 32 bytes. Does n't it vary
depending on the algorithm use(alg header).

byte[] leftmost = new byte[16];
+for (int i = 0; i < 16; i++){
+leftmost[i]=digest[i];
+}


at_hash
  OPTIONAL.  Access Token hash value.  Its value is the base64url
  encoding of the left-most half of the hash of the octets of the
  ASCII representation of the "access_token" value, where the hash
  algorithm used is the hash algorithm used in the "alg" parameter
  of the State Token's JWS [JWS] header. * For instance, if the "alg"*
*  is "RS256"*, hash the "access_token" value with SHA-256, then take
  the left-most 128 bits and base64url encode them.  The "at_hash"

 Hi all,
 I have planned to develop $subject as described below using Apache
 Abdera framework.

 *Intro*
 RSS/Atom Connector for creating, editing, and publishing web feeds and
 other web resources.

 *Methods*


1. Retrieving resources (GET)   :retrieve feeds and inject to esb
mediation logic resources using the our Connector is straightforward: If
the resource is not an XML document, the ClientResponse object can 
 provide
an InputStream. The ClientResponse object provides access to all of the
response headers such as ETag and Last-Modified.
2. Creating resources (POST) :
3. Updating resources (PUT)
4. Deleting resources


 other then that Connector we will have the features

- SSL-protected endpoints
- customize options for a client request
- Custom HTTP methods
- HTTP Authentication mechanisms
- HTTP cookies
- HTTP Cache-Control mechanism


 and also Support for format and protocol extensions and can create Atom
 Publishing Protocol server.

[Dev] BAM JMX Toolbox not showing stats

[John Hawkins]

Hi Folks,

Trying to get the BAM JMX Toolkit working.

I can see all the stats flowing through to cassandra (from my esb). I can
see the hive script putting them into the local h2. I can see the stats in
the h2 but the pretty graphs are not being filled out - they show the
message "No data available. Please visit our docs to see how to configure
JMX monitoring"

I know that the page is connecting to the DB OK because it is retrieving
the information about which servers are in the DB. I've done some java
console debugging and can see the functions being called to reload the
iframes (debug in [1]) . However, I can see that a field - rname is not
filled out (comes out as a blank string) . This variable appears to have to
be loaded from a combo box - rname-dd.
However, index.jsp does not appear to have such a combo box !

Any ideas folks - is there a script not being loaded or something else?

thanks,
John.


[2]
function reloadIFrame(param){
var params = param || {};
var server = param.server || "";
var rname = param.rname || "";
var rtype = param.rtype || "";
var t = param.timeGroup || "";
$("iframe").each(function(){
//var id = $(this).attr('id');
var currentUrl = $(this).attr('src');
if(currentUrl.indexOf('?')){
var absUrl = currentUrl.split('?');
currentUrl = absUrl[0];
}
var newUrl = currentUrl+"?server="+encodeURI(server)+"&rtype="+
encodeURI(rtype)+"&rname="+encodeURI(rname)+"&t="+t;
$(this).attr('src',newUrl);
});

Re: [Dev] [ML] Issue while loading the leaf dataset (misreading classes)

[Thushan Ganegedara]

This issue occurs, if I turn the response variable to a categorical
variable. If I get the variable as a numerical variable, the values are
read correctly.

So I presume there is a fault in categorical conversion of the variable.

[Dev] BAM adapters missing?

[John Hawkins]

Hi Folks,
I'm trying to set up an email output event adapter in BAM but there is no
such adapter in the dropdown list. I only see, cassandra, http, JMS,
kafka,logger.
Someone else appears to have had the same problem [1].
All the documentation I read says that they should be there.

Anyone know why we can't see them at all?

Re: [Dev] [ML] Progress with Deeplearning Component

[CD Athuraliya]

Hi,

Sort option for feature column will now use natural sorting (both ascending
and descending) [1]. Still the initial load will not be sorted. It appears
that DataTables plugin fails to apply natural sorting for initial load.

[KasunG Gajasinghe]

Hi,

This is to update that the next carbon-deployment release is 4.5.0.

AS will need a Jaggery release on top of carbon-deployment 4.5.0 for the AS
5.3.0 beta release.

Thanks,

Re: [Dev] [CEP] Help on TimeWindowProcessor

[Pranavan Theivendiram]

Hi Suho,

The following is sample execution plan query. Here we are getting one
result as value. Can I get three values using this kind of queries?

*The Query* [1]


from health_second_der_concat [health_description == 'memory_consumption']
   *#window.stratos:secondDerivative(1 min, value)* select cluster_id,
cluster_instance_id, network_partition_id, value as
second_derivative_memory_consumption
   insert into second_derivative_memory_consumption_stats
   partition by health_second_der_cluster_partition;

*The annotation in SecondDerivativeWindowProcessor* [2]


@SiddhiExtension(namespace = "stratos", function = "secondDerivative")

Here they are getting only one value. Can you point me out a way that
I can have all three here?


Thanks

 Hi All,

 I am working on writing a custom TimeWindowProcessor (SlidingWindow) to
 handle the curvefitting prediction. I followed the this implementation [1]
 and referred this documentation[2]. In my case, I need to get the events
 received during the 10 mins and use it for the calculation of the curve
 fitting and set the co efficient of curve fitting as a event. I am finding
 it hard to understand how the input events will reach the window processors
 and how the output events are passed throughout and what is the purpose of
 the processevent method. Processevent method is called in the run method on
 the expired events in the TimeWindowProcessor class. But that is not the
 case I wanted.  I want to simply remove the expired events, but rather
 calculate the curve coefficients on active events and to send the
 coefficient as output events. I am bit confused in flow and out flow to the
 TimeWindowProcessor class.

 If anyone can directly point out the input events in the
 TimeWindowProcessor class that would be a great help for me.I really expect
 a help in the form of the tutorial or some explanations on this or pointing
 out some custom TimeWindowProcessor class.

 Note : I already have written evenformatters and executionplans. This
 is the point I got stucked. I really can`t find a good explanation about
 the TimeWindowProcessor class.

[Dev] [APIM-1.9.0] Add external API Stores

[Pubudu Gunatilaka]

Hi,

I was able to do the $subject by following [1]. In this approach
configuration resides in the registry. I found another way of adding
external API Stores which is used in API Manager 1.6.0 in [2]. I followed
the same steps in API Manager 1.9.0. Although it list down external stores
in the publisher, I am getting following error when trying to store an api.

*ERROR - external:jag java.lang.NullPointerException: null*

Does this second approach[2] support in API Manager 1.9.0?

My intention is to automate of adding external API Stores. Therefore it is
needed to add from configuration files rather than using registry
resources. Is there any other approach I can follow?

[1] -
https://docs.wso2.com/display/AM190/Publish+to+multiple+external+API+stores

Re: [Dev] [Architecture] Carbon Spark JDBC connector

Hi Niranda,

Are we going to solve those limitations before the GA? Specially limitation
no.2. Over time we can have stat table with thousands of records, so are we
going to remove all the records and reinsert every time that spark script
runs?

Re: [Dev] [CEP] Help on TimeWindowProcessor

[Sriskandarajah Suhothayan]

You could do some thing like below, and replace firstd, secondd, thirdd
values within the extension with the computed results.

define stream health_second_der_concat (cluster_id, cluster_instance_id,
network_partition_id, value )

define stream health_second_der_concat_temp (cluster_id,
cluster_instance_id, network_partition_id, value, firstd double, secondd
double, thirdd double)

from health_second_der_concat
select cluster_id, cluster_instance_id, network_partition_id, 0.0 as firstd,
0.0 as secondd, 0.0 as thirdd
insert into health_second_der_concat_temp

from health_second_der_concat_temp [health_description == 'memory_consumption']
   *#window.stratos:secondDerivative(1 min, value, *firstd, secondd, thirdd*)*

select *

   insert into second_derivative_memory_consumption_stats
   partition by health_second_der_cluster_partition;

 For you predictions how many inputs you have (input attributes used for

 If you are generating one value then you have to extend an Output
 aggregator. e.g.[1]

Re: [Dev] [APIM-1.9.0] Add external API Stores

[Sam Sivayogam]

Hi Pubudu,

You have to set the className when adding a external store in APIM 1.9.0.
so when you are adding your configuration to api-manager.xml make sure you
have set the className.



Thanks,
Sam

Re: [Dev] How can we pass parameters to WSO2 identity server Assertion Consumer URL

[Akila Ravihansa Perera]

Hi,

As explained in the SOF answer, you can use RelayState parameter for this
purpose. In the SSO agent provided in WSO2 IS samples, there is a
properties file for SSO configuration in each webapp. For eg: in
travelocity.com sample [1], you can find SSO related configuration in
travelocity.properties file in travelocity.com/WEB-INF/classes dir. There
is a property named "SAML.Request.Query.Param" that you can use to pass
additional parameters in HTTP URI format. If you need to pass dynamic
parameters you will have to modify the SSO agent code [2].

[1]

[2]

Thanks.

Hi,

It seems you have secured the App and trying to access it anonymously. Try
allowing anonymous access to the App .

[Dev] AXIOM issue in File Connector

[Malaka Silva]

Hi,

I was checking the ESB File connector and found the following issue.

In file connector we open the input stream to read the file and close it in
the finally block.

We are using the builder based on the content-type or file type.

However expected behavior with axiom is it'll only build the structure at
the time of consuming. This may happen later in the mediation flow or when
sending the message. But by that time stream is already closed and only
part of the message will be send.

In order to fix this I have checked by adding [1]. This works for some
files. However if there are large files and when using relaybuilder issue
still exists. I have added [2] and it seems to be working fine.

But this is not the best solution. Any idea about this?

[1] documentElement.build();
[2] documentElement.toString();

Best Regards,

[Dev] Simple Tool to analyse jar files for packages they contains and OSGI bundles to see packages they export and import

[Rajith Vitharana]

Hi All,

I have created a small java tool [1] to analyse OSGI bundles and analyse
all kinds of jar files. Basically did this for two reasons.

1) When adopting the OSGI best practices, needed to find out whether final
outcome of bundle contains correct information. (For this
MetaInfoExtractor.java class can be used)

2) When debugging applications sometimes need to find what are the packages
it contains. (This is not that important. but I faced with a situation
where I couldn't find the bundle which contains specific package. So to
resolve that created JarFileExtractor.java class)

We can specify a "jarFolderToBeAnalysed" and "tempFolder" folder in the
tool. What it does is, copy each and every jar inside
"jarFolderToBeAnalysed" folder(Iterate through whole folder structure) to
the "tempFolder" folder, analyse them inside "tempFolder" folder and create
text files with the jar name in it.

Note that this is a basic tool so you need to open that in a IDE and run it
(Need to modify to work in CLI)

Hope this will help people who faced with similar issues

Re: [Dev] unknown directive "sticky" when configuring Nginx

[Lakshani Gamage]

Hi Udara,

When I was configuring nginx, I got the same issue.

I followed the following steps to fix the issue.

1. Remove every thing related to Nginx.

sudo apt-get purge nginx nginx-common

2. Install the Nginx plus using instructions in
 https://cs.nginx.com/repo_setup 

3. Add your configuration files and restart the nginx server.

Thank You,

Re: [Dev] unknown directive "sticky" when configuring Nginx

[Akila Ravihansa Perera]

Hi Udara,

Sticky sessions are only available in Nginx Plus (enterprise version). Or
else you need to compile Nginx with sticky session module [1] to get it
working.

Thanks.

Re: [Dev] [Architecture] Carbon Spark JDBC connector

[Niranda Perera]

Hi Gihan,

are we talking about incremental processing here? insert into/overwrite
queries will normally be used to push analyzed data into summary tables.

in the spark jargon, insert overwrite table means, completely deleting the
table and recreating it. I'm a confused with the meaning of 'overwrite'
with respect to the previous 2.5.0 Hive scripts, are doing an update there?

[Dev] [APPM] JWT is signed by AppM gateway. But not the IDP. WDYT?

[Sajith Abeywardhana]

Hi all,

AppM use JWT for transfer claims between AppM gateway and the backend
application. JWT has been generated by extracting user claims from the SAML
response which is provided by the IDP. Currently JWT is signed by the AppM
gateway but not by the IDP.

I think we need to sign the JWT by using the IDP, WDYT?

Re: [Dev] [APPM] JWT is signed by AppM gateway. But not the IDP. WDYT?

[Dinusha Senanayaka]

[Adding Prabath]

In API Manager, JWT is generated as a part of key validation process (key
manager) , hence the JWT is signed by KeyManager (IdP). But in App Manager,
JWT generation happens at the gateway using the SAML response sent by IdP.
Since GW is the one generating JWT, problem is how we are going to get it
signed by IdP. Seems it's a valid requirement.

[Dev] Unable to publisher and store with public IP

[Chandana Napagoda]

HI ES Team,

We have hosted ES 2.0.0 pack in EC2 instance and tried to access it through
public network. For that, we have updated the carbon.xml,
 sso-idp-config.xml(store and publisher) and  authenticators.xml files with
public IP address. However, the publisher and store applications are still
redirecting to the EC2 private address. But we can access mgt console with
public IP.

Do we need do additional configurations other than mentioned changes?

Regards,
Chandana

Re: [Dev] [DEV][APPM] Can't call WebApps in Appm Internal deployment

Hi Lakshani,

If this is not already sorted, please check the code. Seems "WebAppInfoDTO"
 is getting null. WebAppInfoDTO is populate from the DB values. Check your
DB configurations are right and those info get added to DB when you are
creating a new app.
