+ Apache Camel: Twitter Websocket Example +

Twitter Websocket Example

+

Available as of Camel 2.10

+ +

This example is located in the Camel distribution at examples/camel-example-twitter-websocket.

+ +

The example is demonstrating how to poll a constant feed of twitter searches and publish results in real time using web socket to a web page.
+As usual the code in Camel is very simple. All it takes is roughly

+ +

+

+  from("twitter://search?...")
+    .setHeader("websocket.sendToAll", "true")
+    .to("websocket:camel-tweet")
+

+

+ +

To use twitter, you need a twitter account which have setup an application to be used.
+For twitter users, you may be familiar that twitter requires you to grant applications access to your twitter account, such as twitter for iphone etc.
+The same applies for this example. You can read details about how to setup a new twitter application at the Camel Twitter documentation.

+ +

In your Twitter settings under the Apps menu, it will list your approved applications. For example I created an application named "Camel-Example"
+which is now listed as approved with read-only access.
+

+ +

When you have created an application, you get a number of details back from twitter
+which you need to use the twitter component. Enter these details in the source code at:
+ src/main/java/org/apache/camel/example/websocket/CamelTwitterWebSocketMain.java
+in the constant fileds, by replacing the values "INSERT HERE".

+ +

You will need to compile this example first:

+

+mvn compile
+

+

+ +

To run the example type

+

+mvn exec:java
+

+

+ +

Then open a browser to see live twitter updates in the webpage

+

+http://localhost:9090
+

+

+ +

To stop the example hit ctrl + c

+ +

When the application runs, the webpage should automatic update with new tweets. A screenshot below illustrates what you would see:
