Hi Aditya,
In order to preserve the double quotations around the numbers, you can
configure the below property in
/repository/conf/synapse.properties
synapse.commons.json.output.autoPrimitive=false

Re: [Dev] How to catch an error from the REST Task in the BPMN
Hi Thomas, When a failure occurs in a REST task, a BPMN error with error code "RestInvokeError" will be thrown. This error can be caught using an Error Boundary Event associated with the REST service task. You can find an example of using this in the article[1]. [1] http://wso2.com/library/articles/2016/04/article-how- to-model-bpmn-business-processes-with-wso2-business-process-server/ Thanks, Manorama.

Re: [Dev] Enriching the response array with corresponding elements in the request array . Facing issue, require guidance.
Hi Aditya,
You can enrich the AggregateMediator response using input request without
as below.
Inside the iterate mediator store the input payload in a property as below.
In the outSequence, before aggregate, you can enrich the backend response with
the above property value.
.
.
.
Thanks,
Manorama

[Dev] IS Analytics - Handling zero values in Login Attempts over Time chart
Hi all, In Authentication dashboard we show login attempts using an area chart. The current implementation of this chart doesn't show zero values when there are no login attempts corresponding to some points of time within the selected period of time. For example, as described in [1], consider following scenario where we have login events from 10.10 AM to 10.25 AM >From 10.10 - 10.13 - There are some login attempts >From 10.14 - 10.17 - *Zero login attempts* >From 10.18 - 10.25 - Some login attempts Currently we are showing the above information in the chart as follows, [image: Inline image 1] In this chart we are not showing the information about the zero login attempts. In order to show these information, we have changed the chart as below, [image: Inline image 2] Now it is showing the zero login attempts. But the chart now is divided into two areas. What is the better way to draw chart when we have zero login attempts. Appreciate any suggestions and opinions on this.

Re: [Dev] Sample Execution Summary -ML
Thanks Fazlan for reporting this issue. This issue is due to the improvements done in feature type (categorical/numerical) identification algorithm. In the above mentioned samples, wine-quality dataset [1] has been used. According to the new algorithm, the response variable quality, is identified as a categorical feature. As all these are numerical prediction algorithms, and require a numerical variable as the response variable, this exception[2] is thrown. I've fixed it in [3] [1] https://archive.ics.uci.edu/ml/datasets/Wine+Quality [2] org.wso2.carbon.ml.core.exceptions.MLModelBuilderException: An error occurred while building supervised machine learning model: Categorical attribute quality cannot be used as the response variable of the Numerical Prediction algorithm: [3] https://github.com/wso2/product-ml/pull/228 Thanks.

Re: [Dev] [ML][CEP] Server startup error when installing ML features in CEP
Hi Nirmal,
As we discussed earlier, there wasn't any requirement to support
predictions via rest api call, after we switched to predictions without
using spark runtime.
(I'm referring to mail thread 'WSO2 ML Prediction without Spark Runtime')
Thanks.

Re: [Dev] Please review and merge PR
Hi Supun, I've tested for quoted column headers using the linear regression sample, by adding beginning and ending double quotes to the column headers of the dataset. "fixed acidity","volatile acidity","citric acid",., "quality" Model building and prediction were successful. As you've mentioned, the model building failure issue might have been fixed with some earlier changes. Thanks.

Re: [Dev] Please review and merge PR
The issue noticed is, the analysis steps cannot be proceeded after the explore step. There's no exception trace shown. The ajax request sending fails when double quotes are included in the json payload. Thanks. On Mon, Jun 1, 2015 at 2:21 PM, Nirmal Fernando wrote: > Merged.

Hi Lasantha, Tharik,
Thanks for the clarifications.
I'll update the adapter references in ML accordingly.
Thanks

[Dev] Issue while trying to access installed features at the ESB mediator initialization
Hi, I'm implementing the ESB mediator for WSO2 Machine Learner. To use this mediator, Machine Learner features need to be installed in the ESB. I have a requirement to create a new instance of org.wso2.carbon.ml.core.impl.MLModelHandler at the mediator initialization. (MLModelHandler class will be avaiable in the classpath once the Machine Learner feature is installed) At the initialization of the MLModelHandler, it needs to read some configuration files (in repository/conf). I tried the following steps and got the below mentioned exception, indicating that the proxy cannot be loaded. 1. Add the machineLearner mediator in the inSequence of a proxy service. (Machine Learner feature is already installed in ESB) 2. Restart the ESB server 3. At the server startup, a null pointer exception is thrown as below, indicating that the configurations required at the initlializatoin of org.wso2.carbon.ml.core.impl.MLModelHandler are not loaded. WARN - SynapseXMLConfigurationFactory Proxy Service configuration: MLMediatorTestProxy cannot be built - Continue in fail-safe mode java.lang.NullPointerException at org.wso2.carbon.ml.core.utils.ThreadExecutor.(ThreadExecutor.java:32) at org.wso2.carbon.ml.core.impl.MLModelHandler.(MLModelHandler.java:68) at org.wso2.carbon.mediator.machinelearner.util.ModelHandler.(ModelHandler.java:65) at org.wso2.carbon.mediator.machinelearner.MachineLearnerMediator.(MachineLearnerMediator.java:45) at org.wso2.carbon.mediator.machinelearner.xml.MachineLearnerMediatorFactory.createSpecificMediator(MachineLearnerMediatorFactory.java:46) I noticed that, at the ESB server start-up, the mediator constructor is called twice per each proxy server configuration. However at the second time of mediator initialization, the configurations are available. So the proxy service is loaded successfully. It seems that the proxy is loaded before loading the configuration files required for the installed Machine Learner feature. How can I overcome this issue? Isn't it a good practice to access the installed features at the mediator initialization? As a solution, I can use the lazy loading approach. So that the new instance of org.wso2.carbon.ml.core.impl.MLModelHandler will be initialized only when the first message comes to the the mediator's mediate() method. Is this a suitable approach?

Re: [Dev] Axis2 server bundled with the ESB cannot be started when AXIS2_HOME is set
Hi, Thank you Prasanna and Udara! 'unset AXIS2_HOME' seems to be the easy way, without editing .bashrc file. It worked fine.

[Dev] Axis2 server bundled with the ESB cannot be started when AXIS2_HOME is set
I've tried to run the ESB sample according to the tutorial[1]. When I try to start the Axis2 server it displays the following message on console. ls: cannot access /home/manorama/axis2-1.6.2/../../repository/components/plugins/*.jar: No such file or directory ls: cannot access /home/manorama/axis2-1.6.2/../../repository/components/plugins/*.jar: No such file or directory Using JAVA_HOME: /usr/local/java/jdk1.7.0_03 Using AXIS2 Repository : /home/manorama/axis2-1.6.2/repository Using AXIS2 Configuration : /home/manorama/axis2-1.6.2/repository/conf/axis2.xml Error: Could not find or load main class samples.util.SampleAxis2Server I've another standalone Axis2 server installed in /home/manorama/axis2-1.6.2, and the AXIS2_HOME variable is set to that installation directory. According to the above message, AXIS2 Repository and AXIS2 Configuration refers to the location given by AXIS2_HOME variable. When I removed the AXIS2_HOME variable, server started as expected. Is there any configuration need to be done in ESB to avoid referring to the AXIS2_HOME varialble or just removing AXIS2_HOME from .bashrc is enough?
