Why does integration always seem to be the most time consuming and tedious part of Web app development? Mule iBeans (http://www.mulesoft.org/ibeans) provides a dramatically simpler approach to integrating your applications with data sources and services. iBeans allows your webapps, using Java or Javascript, to interact with other webapps and services by providing a simple API and annotations that enable your webapp to perform common tasks. Whether you are building a “full-boat” SOA infrastructure or just need a simple point-to-point solution embedded in your web app, the Mule iBeans open source project can help. Learn how to integrate cloud services like twitter, flickr and google into your Java apps with virtually no code.

31. The @Call and @UriParam Annotations public interface TwitterIBean { @Call (uri = " http://www.twitter.com/statuses/show/{id}.json ") String statusesShow( @UriParam (" id ") String id) throws CallException; } All contents Copyright © 2009, MuleSoft Inc.

32. The @State Annotation public interface TwitterIBean { @State void init( @UriParam (“ format ”) String format); @Call (uri = “ http://www.twitter.com/statuses/show/{id}.{format} ”) String statusesShow( @UriParam (" id ") String id) throws CallException; } All contents Copyright © 2009, MuleSoft Inc.

33. Static Defaults public interface TwitterIBean { @UriParam (“ format ”) static String DEFAULT_FORMAT = “ json ”; @State void init( @UriParam (“ format ”) String format); @Call (uri = " http://www.twitter.com/statuses/show/{id}.{format} ") String statusesShow( @UriParam (" id ") String id) throws CallException; } All contents Copyright © 2009, MuleSoft Inc.

34. The @ReturnType Annotation and Generic Types public interface TwitterIBean { @UriParam (“ format ”) static String DEFAULT_FORMAT = “ json ”; @State void init( @UriParam (“ format ”) String format, @ReturnType Class retType); @Call (uri = &quot; http://www.twitter.com/statuses/show/{id}.{format} &quot;) <T>T statusesShow( @UriParam (&quot; id &quot;) String id) throws CallException; } All contents Copyright © 2009, MuleSoft Inc.

35. Always provide sensible defaults public interface TwitterIBean { @UriParam (“ format ”) static String DEFAULT_FORMAT = “ json ” ; @ReturnType static Class DEFAULT_RETURN_TYPE = String. class ; @State void init( @UriParam (“ format ”) String format, @ReturnType Class retType); @Call (uri = &quot; http://www.twitter.com/statuses/show/{id}.{format} &quot;) <T>T statusesShow( @UriParam (&quot; id &quot;) String id) throws CallException; } All contents Copyright © 2009, MuleSoft Inc.

36. Testing the iBean public class TwitterIBeanTest extends AbstractIBeansTestCase { @IntegrationBean private TwitterIBean twitter; public void testTwitter() throws Exception { twitter.init(“ xml ”, Document. class ); Document doc = twitter.statusesShow(“ 1234567890 ”); } } All contents Copyright © 2009, MuleSoft Inc.

37. Other Annotations Annotation Description Type @HeaderParam Configures a header on the outgoing message Param, Field @PayloadParam Used for Http, configures a POST parameter Param @Payload Attaches data to the body of the message Param @State Will store values on the instance of the bean for later reference Method @PropertyParam Adds a property to the message that can be used later i.e. user/pass for authentication Param, Field All contents Copyright © 2009, MuleSoft Inc.

38. Transforming Response Data public class TwitterTransformers { @Transformer protected Status twitterXmlToStatus(Document doc) { String status = selectValue(&quot; /status/text &quot;, doc); String user = selectValue(&quot; /user/name &quot;, doc); return new Status(status, user); } } All contents Copyright © 2009, MuleSoft Inc.

40. Application Annotations Annotation Description Type @Schedule Cron scheduling for calling a method, can be used to poll channels Method @Receive Receive Data on a channel URI Method @Send Send the return of the method on a channel URI Method @ReceiveAndReply Receive Data on a channel URI and send the return back to the caller Method All contents Copyright © 2009, MuleSoft Inc.

41. @Schedule, @Send Example public class TwitterSchedule { @IntegrationBean private TwitterIBean twitter; @Schedule (interval = 5000) @Send (uri = &quot; ajax:///ibeans/ajax/twitter &quot;) public Document getTimeline() throws Exception { twitter.init(“ xml ”, Document. class ) return twitter.getPublicTimeline(); } } All contents Copyright © 2009, MuleSoft Inc.
