Page Created : CAMEL : Tutorial-Example-ReportIncident Tutorial-Example-ReportIncident has been created by Claus Ibsen (Jul 15, 2008). Content: Tutoral on the camel-example-reportincident Information Work in progress by Claus Ibsen. Tutorial to be part of Camel 1.5. (CAMEL-601) Introduction Creating this tutorial was inspired by a real life use-case I discussed over the phone with a college. He was working a client that uses a heavy-weight integration platform from very large vendor. He was in talks with contractors to implement a new integration on this heavy piece of platform - his trouble was though that the price was tripled when the contractors heard it had to be on this platform. So I was wondering how we could do this integration on Camel. Can it be done in one day. This tutorial is written during the development of the integration. I have decided to start off with a sample that isn't Camel's but standard Java and then plugin Camel as we goes. Just as when people needed to learn Spring you could consume it piece by piece, the same goes with Camel. The use-case The goal is to allow staff to report incidents into a central administration. For that they use client software where they report the incident and submit it to the central administration. As this is an integration in a transition phase the administration should get these incidents by email whereas they are manually added to the database. The client software should gather the incident and submit the information to the integration platform that in term will transform the report into an email and send it to the central administrator for manual processing. TODO: Figure with: Client -> Integration Platform -> Central Administration In EIP patterns TODO: Figure with EIP patterns Initial Project Setup We want the integration to be a standard .war application that can be deployed in any web container such as Tomcat, Jetty or even heavy weight application servers such as WebLogic or WebSphere. There fore we start off with the standard Maven webapp project that is created with the following long archetype command: mvn archetype:create -DgroupId=org.apache.camel -DartifactId=camel-example-reportincident -DarchetypeArtifactId=maven-archetype-webapp Notice that the groupId etc. doens't have to be org.apache.camel it can be com.mycompany.whatever. But I have used these package names as the example is an official part of the Camel distribution. Then we have the basic maven folder layout. We start out with the webservice part where we want to use Apache CXF for the webservice stuff. So we add this to the pom.xml TODO: pom with CXF Developing the WebService As we want to develop webservice with the contract first approach we create our .wsdl file TODO: wsdl file CXF wsdl2java Then we integration the CXF wsdl2java generator in the pom.xml so we have CXF generate the needed POJO classes for our webservice contract. TODO: CXF wsdj2java Configuration of the web.xml TODO: how to configure the web.xml, spring context listener, cxf files etc. Running our webservice TODO: Adding Jetty to pom TODO: Generation the code TODO: Adding the System.out and dummy response TODO: Starting Jetty and using SoapUI to hit the webservice TODO: Starting Jetty in debug mode so we can debug online Adding a unit test TODO: CXF unit test End of part 1 TODO: Conclusion. Then
