Analyzing twitter using JBossESB
Most ESB example start from some HelloWorld use case, where you have to send a message to the ESB and it will print it to the console. In this post I would like to show that you can do a lot more with an ESB, for example reading and analyzing data from social media like twitter.
The example below will demonstrate how you can use JBossESB to retweet every message containing a certain hashtag. If you want you can extend the example and store all the messages to database, or keep track of those users who have posted the most amount of messages with a certain content.
- JBoss AS 6.1 installed
- JBoss ESB 4.10 integrated
- Also add the twitter4j library to the JBoss library folder
Step 1) Create a scheduler using JBossESB
When you want to retweet all messages containing a certain hashtag, you need some kind of scheduler that is fired every second, minute or hour. In the jboss-esb.xml file you can do this by using a 'schedule-provider'.
