The facebook component can be configured with the Facebook account settings below, which are mandatory. The values can be provided to the component using the bean property configuration of type org.apache.camel.component.facebook.config.FacebookConfiguration. The oAuthAccessToken option may be ommited but that will only allow access to application APIs.
Producer endpoints can also use a special option inBody that in turn should contain the name of the endpoint option whose value will be contained in the Camel Exchange In message. For example, the facebook endpoint in the following route retrieves activities for the user id value in the incoming message body.
Endpoints that return a String return an Id for the created or modified entity, e.g. addAlbumPhoto returns the new album Id. Endpoints that return a boolean, return true for success and false otherwise. In case of Facebook API errors the endpoint will throw a RuntimeCamelException with a facebook4j.FacebookException cause.
Rather than the endpoints returning a List (or facebook4j.ResponseList) through a single route exchange, camel-facebook creates one route exchange per returned object. As an example, if \"facebook://home\" results in five posts, the route will be executed five times (once for each Post).
The reading option of type facebook4j.Reading adds support for reading parameters, which allow selecting specific fields, limits the number of results, etc. For more information see Graph API documentation.
The reading option can be a reference or value of type facebook4j.Reading, or can be specified using the following reading options in either the endpoint URI or exchange header with CamelFacebook. prefix.
Java Dependency Injection design pattern allows us to remove the hard-coded dependencies and make our application loosely coupled, extendable and maintainable. We can implement dependency injection in java to move the dependency resolution from compile-time to runtime.
The UMS API provides a plain old java (POJO/POJI) programming model and this eliminates the needs for application developers to package and implement various Java EE modules (such as an EJB module) in an application to access UMS features. This reduces the complexity of the client application, and also, reduces application development time because developers can create applications to run in a Java EE container without performing any additional packaging of modules, or obtaining specialized tools to perform such packaging tasks.
Client applications can specify a set of parameters at runtime when instantiating a MessagingClient object. For example, you configure a MessagingClient instance by specifying parameters as key-value pairs in a java.util.Map. Among other things, the configuration parameters serve to identify the client application, point to the UMS server, and establish security credentials. Client applications are responsible for storing and loading the configuration parameters using any available mechanism.
This solution worked for us through Java 8, but when we upgraded to Java 11, the -Djavax.accessibility.assistive_technologies flag triggers a crash because it incorrectly specifies that we want to load an AccessibilityProvider with empty string as a name, instead of an empty list of providers. The change in the parsing happened in this changeset in Java 9. I filed a bug report, but I also needed a new workaround.
Since there is now no way to specify \"load no classes\", to override the accessibility settings to NOT load com.sun.java.accessibility.AccessBridge we need to load a class of our own. Here's my simple implementation of a no-op AccessibilityProvider:
We tried to implement both texting (SMS) and facebook messaging, but ran into a lot of trouble with both. We ultimately decided to scrap the facebook part and just focus on the SMS portion of our project.We were working with Twilio but have several issues with Twilio sdk. Unfortunately, we didn't find anyone with Twilio and Android experience to help. 1e1e36bf2d
