I'm planning to create a custom message processor to pick up messages from message store. However I haven't find any examples how to create a custom class. Documentation under this topic is very limited.(http://docs.wso2.org/display/ESB481/Custom+Message+Processor). Can somebody provide example to create custom message processor ?
Thanks,
Have a look at the MessageProcessor interface - and the implementations and other classes here. Once you have your processor setup, you can place your jars in the lib folder. Then follow the instructions in the link you posted in the OP.

According to the docs here:
https://ci.apache.org/projects/flink/flink-docs-release-1.11/dev/table/connectors/
and
https://ci.apache.org/projects/flink/flink-docs-release-1.11/dev/table/connectors/
is it possible to create a custom ddl RabbitMQ connector to be used in pyflink TABLE API 1.11?
how?
Firstly, you need to implement your custom connector implementation based on the interface provided by Java. Then you need to use the API or command line parameters to refer to the jar used which you can refer to
https://ci.apache.org/projects/flink/flink-docs-release-1.11/dev/table/python/common_questions.html#adding-jar-files
I have setup Presto with mysql connector enabled.
Now I want to write my own connector for a special type of data source.
Custom connector for SQLAlchemy is done. But this time, I am facing dozens of Java classes. What base classes can be used as good starting point? Which interfaces must be implemented? Maybe RawFile connector?
Thank you in advance.
See the developer documentation: https://prestodb.io/docs/current/develop/connectors.html. The example HTTP connector is a good starting point.
You need to implement ConnectorFactory, Connector, ConnectorMetadata,
ConnectorSplitManager, ConnectorHandleResolver, and either ConnectorRecordSetProvider or ConnectorPageSourceProvider at the minimum, other classes may be needed depending on what you want to do.
I am new in apache camel. I want to do a GET REST call to get data and then I want to mapping these data to my Java bean. How can I do that with camel? I want to do it in a spring MVC web application.
I know how to do it with RestTemplate for example, but I want to use apache camel.
I've checked this documentation http://camel.apache.org/cxfrs.html but still I don't know how to set up for accomplishing this.
Please if you can provide some examples will be great.
There are a few different options. I'll walk through one...
First, define your rest configuration with bindingMode=auto
restConfiguration()
.component("jetty").host("0.0.0.0").port(9000)
.bindingMode(RestBindingMode.auto);
Next, when you define your particular rest service, specify a type (this is the type of the incoming body:
rest("/")
.put("/A/{subpath1}/{subpath2}")
.type(MyPojo.class)
.to("direct:XYZ");
That's it! The unmarshalling will be magical ;)
Alternatively, you can unmarshal things yourself.
If you'd like to see a working example of the above, check out this program: it has a main() to test it. https://github.com/DariusX/CamelSandbox/blob/master/CamelSandbox/src/main/java/com/zerses/camelsandbox/rest/RestConsumerBindingTest.java
I'm working through the NServiceBus ServiceMatrix tutorial, and am trying to understand:
All defined events will be put in the Contracts project.
All commands will be put in the Internal project.
I'm not tracking the intuition here. Why are commands considered an internal notion? Aren't they part of the public contract that other components would need to know about? Why not define all commands and events in the same 'Contracts' project?
Corey,
The reasoning is that commands should be sent only between components that belong to the same logical service, and not between services. Events can be transmitted between logical services.
Is it possible to use mule message properties (like payload and flowvars) in a Mule Management Console notification body or subject?
I think it's not possible.
You can only use the properties exposed by mule, as explained here:
http://www.mulesoft.org/documentation/display/current/Defining+SLAs+and+Alerts#DefiningSLAsandAlerts-PropertiesUsedinAlertExpressions
Maybe using a Management Script, but there is no much info about it (the links to the javadoc are broken)
http://www.mulesoft.org/documentation/display/current/Scripting+Examples#ScriptingExamples-AlertingExamples
Yes you can use it. Mule provide various properties common to all alerts from class com.mulesoft.console.alert.RaisedAlert that can be used in defining the certain values such as
Flow identifier
Flow name
You may refer to mule documentation for it
https://docs.mulesoft.com/mule-management-console/v/3.7/defining-slas-and-alerts#DefiningSLAsandAlerts-PropertiesUsedinAlertExpressions
