I'm trying to build a service that also (beside of SOAP) uses CORBA/IIOP for communication. I followed the (CXF) CORBA Bank Demo and manged it to get it running. But despite of what is written in the README-File it needs no corba naming service.
What I need is, that the server registers it's service at a corba nameing service and the client looks up the server through the nameing service. Is there any way to achieve this goal ?
The bank demo uses a file to store the reference. The "corba/hello_world" sample uses a "corbaname" url in the wsdl to force the use of a naming service. Check that one or the "bank_ws_addressing" sample which also uses the corbaname urls.

I am working on a project and I am forced to not using Spring Boot. I have a Eureka server running on localhost:8090 and some services already registered on it.
How can I force Apache Camel's serviceCall to look for services on the Eureka server?
I know that to make it work for Consul as the service discovery you should do something like following:
ConsulConfiguration config = new ConsulConfiguration();
config.setUrl("http://ip:port");
ConsulServiceDiscovery discovery = new ConsulServiceDiscovery(config);
// configure camel service call
ServiceCallConfigurationDefinition config = new ServiceCallConfigurationDefinition();
//config.setServiceDiscovery(servers);
// register configuration
camelContext.setServiceCallConfiguration(config);
How to make it work for Eureka server on localhost:8090??
there’s no direct support for eureka in camel so if you can’t use spring-boot, you need to build your own ServiceDiscovery implementation
As #Luca suggested and after some research I came to this conclusion that you should implement a custom service discovery to read from Eureka. In order to do that I did the following:
Extending my EurekaServiceDiscovery class from DefaultServiceDiscovery class of camel-core module
Overriding the method public List getServices(String name) of
DefaultServiceDiscovery class which is responsible to retrieve services from Eureka
Using Eureka REST API to get all the services in the overrided method. In order to do this you should convert the recieved JSON data from Eureka REST API to appropriate java classes. You need to define Application and InstanceInfo classes based on those JSON data.
For example after running Eureka on localhost:8090 and after registering a service named account-service on it, you can git information of account-service by sending a Http.GET request to localhost:8090/eureka/apps/account-service

I want to know if there is an api for java to integrate the data from the site into the myob database like inventory of a customer
The answer depends on which "MYOB database" you are referring to.
"v19" product range: use a JDBC-ODBC bridge.
"EXO": you can use JDBC SQL-Server driver, or use the REST API documented here.
"AccountRight Live" (desktop or cloud): use the REST API documented here.
"Essentials": use the REST API documented here.
"Advanced": use the REST API documented here.
Note that solutions involving JDBC drivers typically require that your site be deployed on the same network as the target company file. If not, you will need an intermediate stage to synchronise or post data.
I'm currently developing a mobile application that will fetch data from server by request (page load) or by notification received (e.g. GCM).
Currently I'm starting to think about how to build the backend for that app.
I thought about using PHP to handle the http requests to my database (mySQL) and to return the response as JSON. As I see it there are many ways to implement such server and would like to hear to hear thoughts about my ideas for implementations:
1. create a single php page that will receive an Enum/Query, execute and send the results.
2. create a php page for every query needs to be made.
Which of my implementations should I use? if none please suggest another. Thank you.
P.S, this server will only use as a fetcher for SQL and push notifications. if you have any suggestion past experience about how to perform it (framework, language, anything that comes to mind) I'd be happy to learn.
You can use PHP REST Data services framework https://github.com/chaturadilan/PHP-Data-Services
I am also looking for information about how to power a web and mobile application that has to get and save data on the server.
I've been working with a PHP framework such as Yii Framework, and I know that this framework, and others, have the possibility to create a API/Web service.
APIS can be SOAP or REST, you should read about the differences of both to see wich is best for mobile. I think the main and most important one is that for SOAP, you need a Soap Client library on the device you are trying to connect, but for REST you just make a http request to the url.
I have built a SOAP API with Yii, is quite easy, and I have use it to communicate between two websites, to get and put data in the same database.
As for your question regarding to use one file or multiple files for every request, in the case of SOAP built on Yii, you have to normally define all the functions available to the API on the server side in only one file(controller) and to connect to that webservice you end up doing:
$client=new SoapClient("url/of/webservice);
$result=$client->methodName($param1, $param2, etc..);
So basically what you get is that from your client, you can run any method defined on the server side with the parameters that you wish.
Assuming that you use to work program php in the "classic way" I suggest you should start learning a framework, there are many reasons to do it but in the end, it is because the code will result more clean and stable, for example:
You shouldn't be writing manual queries (sometimes yes), but you can use the framework's models to handle data validation and storage into the database.
Here are some links:

http://www.yiiframework.com/doc/guide/1.1/en/topics.webservice
http://www.yiiframework.com/wiki/175/how-to-create-a-rest-api/
As I said, I am also looking to learn how to better power a mobile application, I know this can be achieved with a API, but I don't know if that is the only way.
create a single php page that will receive an Enum/Query, execute and send the results.
I created a single PHP file named api.php that does exactly this, the project is named PHP-CRUD-API. It is quite popular.
It should take care of the boring part of the job and provides a sort of a framework to get started.
Talking about frameworks: you can integrate the script in Laravel, Symfony or SlimPHP to name a few.
In a route (that exposes a REST service) i need to get the local host address/domain (so as I can build links to be included in a response body)
Is there a way to get the local host address from within camel ?
PS : running camel inside servicemix
there isn't a Camel specific way (that I know of), I'd just use an external property file to configure environment specific settings like this...you can then use camel properties to pull this in, etc.
A good idea when posting questions is to provide more details.
Which camel component do you use for REST. And which version of SMX/Camel do you use etc.
As you question assume that the rest component in Camel will expose a hostname information.
This questions is not Camel specific per see, as you can use the regular Java API to get the hostname.
A registry is a list of items with pointers for where to find the items, like the index on a database table or the card catalog for a library.
Correct me if I am wrong, from this definition, what I'd expect from a camel application registry is where a client application can (depending on the client protocol) do a lookup and based on metadata, selects a particular service and uses it as defined.
I am wondering if Apache Camel has anything close to this. Most of the service registries articles/implementations I have seen seems to address only SOAP protocols.
Regards.
You can use the REST API from camel-web to lookup routes and endpoint which is the "services" in Camel.
http://camel.apache.org/web-console.html
In terms of a SOA service registry then you may look at other products which specialize in that such as Apache ZooKepper
http://hadoop.apache.org/zookeeper/
You can use ManagementStrategy SPI to hook into events in Camel and track services as they are created/started/stopped etc. Then you can bridge that to your SOA service registry product of choice.
you can also use the CamelContext getEndpoints() and getEndpointsMap() APIs to browse the endpoints
