is it possible to get access to a HornetQServerControl via the HornetQ core API?
I read the management chapter from the documentation, but still have no idea how to get access. The only example I found in the sources uses JMX.
Thanks
There is an example to access HornetQ managememet API with JMS
https://github.com/hornetq/hornetq/blob/master/examples/jms/management/src/main/java/org/hornetq/jms/example/ManagementExample.java
Using HornetQ core API is similar.
You can also read the test https://github.com/hornetq/hornetq/blob/master/tests/integration-tests/src/test/java/org/hornetq/tests/integration/management/HornetQServerControlUsingCoreTest.java.

Any idea please about the best way to use for back to back communication ?
spring cloud OpenFeign or WebClient/RestTemplate ?
I think Feign client should be used when spring cloud gateway need to
communicate to other microservices, whereas WebClient/RestTemplate should be used for back to back communication.
Am I wrong ?
WebClient (RestTemplate - deprecated to support WebClient)
Supports reactive call
underlying HTTP client libraries such as Reactor Netty
Part of spring framework - WebFlux || Doc will give you more
Comes in 2 flavour - Annotation and functional way
Personally I found it very useful while working with OAuth2 creating bean webClient, before making call it needs to be authenticated with token, ServerOAuth2AuthorizedClientExchangeFilterFunction will ease each call with just one time configuration
OpenFeign
Reactive - need to use 3rd party - com.playtika.reactivefeign
Fits best if you want call in blocking way
Part of Spring cloud
Netflix fully transferred Feign to the open-source community under a new project named OpenFeign
I know that every command that I enter in Kubernetes communicate with API.
Now I want to speak to API directly.
How can I find json format for every command?
I suggest using a client library if you talk from a programming language:
https://kubernetes.io/docs/reference/#api-client-libraries
Or use kubectl if you talk from CLI. Hardcoding API schemas will add you a maintenance burden. You're basically reimplementing the client in this case.
Following is the kubernetes API reference docs, you can find equivalent API for each resources here:
https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.13/
Hope this helps
I am trying to see whether MarkLogic Java API can be used to create a content database and REST Server?
I went through te Java API but I dont see any reference.
Is it possible to create a REST Server through MarkLogic Java API?
I appreciate any links or pointers regarding this.
No, that's beyond the scope of the Java Client API. The Java Client API must connect to a REST Server after it's already created. You can, however, use the /rest-apis service on port 8002 via your favorite generic REST client API for Java. To see an example of how to do this with Apache HttpClient, see Bootstrapper.java. You can use it directly like the unit tests setup util TestServerBootstrapper.java does with this code:
Bootstrapper.main(new String[] {
"-configuser", username,
"-configpassword", password,
"-confighost", host,
"-restserver", "java-unittest",
"-restport", ""+port,
"-restdb", "java-unittest"});
Trying to dynamically create and provide security metadata for artemis mq topics (as opposed to defining them statically in broker.xml).
For that purpose I've implemented (as described here) the SecuritySettingPlugin interface.
Now, the issue is the getSecurityRoles/populateSecurityRoles of the implementation are called only at server startup.
So, at some point in time after the mq server has been started, a topic will be created :
org.apache.activemq.artemis.api.jms.management.JMSServerControl.createTopic("newTopic")
Now I would like artemis to call again my SecuritySettingPlugin implementation to get the updated security roles (which will include configuration for the newly created newTopic).
Is that possible ?
P.S. security-invalidation-interval does not invalidate roles configuration cache.
Seems there is a way to customize an address security by API :
ActiveMQServerControl.addSecuritySettings()
How do I add new Database support (MongoDB) in 2.6.3 version of WSO2 Data Service Server.
You can use DSS (2.6.3) with any database type if the database connectivity is exposed via JDBC. In other words, if your preferred database type exposes a JDBC driver/adapter for the users to connect to it via JDBC then you can use DSS to expose your data stored in your data store as a web service. Similarly, if MongoDB too has a JDBC adapter you wouldn't have any (or too many :) ) issues integrating that with DSS. However, there are some exceptions when it comes to exposing flat files such as google spreadsheeets, excel sheets, csv files as DSS uses the relevant client APIs such as Google gdate client API, Apache POI, etc to connect to those datasources and extract data. However, if we consider the general case is you need to have an adapter or a similar mechanism to connect to your datasource via JDBC.
But in the upcoming version of DSS (v3.0.0), it is planned to introduce custom datasource support so you can easily write an adapter to any datasource and use it with DSS.

I am not sure about this, but I suppose that if is not supported by default you can always download the jar library for MongoDB and put it in CARBON_HOME\repository\components\lib and restart. For example for mysql I have the mysql-connector-java-5.1.7-bin.jar in that folder.
Hope this help
