That should do it (it automatically looks for XML Schemas in src/main/xsd to generate beans for). Run mvn install and it should emit the beans into target/generated-sources/jaxb. Your IDE should see them there, though you may need to update the project to reflect the new settings in the Maven POM.

My sample XSLT template isn't that smart, but it'll get you going if you don't want to write one of your own.

Create a unit test

Here's where we get to some meaty Camel work. We need to:

  • Set up a unit test
  • That loads a Camel configuration
  • That has a route invoking our XSLT
  • Where the test sends a message to the route
  • And ensures that some XML comes out the end of the route

The easiest way to do this is to set up a Spring context that defines the Camel stuff, and then use a base unit test class from Spring that knows how to load a Spring context to run tests against. So, the procedure is:

Set Up a Skeletal Camel/Spring Unit Test
  1. Add dependencies on Camel-Spring, and the Spring test JAR (which will automatically bring in JUnit 3.8.x) to your POM:
    Code Block
    xml
    xml
    
    <dependency>
        <artifactId>camel-spring</artifactId>
        <groupId>org.apache.camel</groupId>
        <version>1.4.0</version>
    </dependency>
    <dependency>
        <artifactId>spring-test</artifactId>
        <groupId>org.springframework</groupId>
        <version>2.5.5</version>
        <scope>test</scope>
    </dependency>
    
  2. Create a new unit test class in src/test/java/your-package-here, perhaps called XMLInputTest.java
  3. Make the test extend Spring's AbstractJUnit38SpringContextTests class.
  4. Create a Spring context configuration file in src/test/resources, perhaps called XMLInputTest-context.xml
  5. In the unit test class, use the class-level @ContextConfiguration annotation to indicate that a Spring context should be loaded
    • By default, this looks for a Context configuration file called TestClassName-context.xml in a subdirectory corresponding to the package of the test class. For instance, if your test class was org.apache.camel.tutorial.XMLInputTest, it would look for org/apache/camel/tutorial/XMLInputTest-context.xml
    • To override this default, use the locations attribute on the @ContextConfiguration annotation to provide specific context file locations (starting each path with a / if you don't want it to be relative to the package directory)
  6. Add a CamelContext instance variable to the test class, with the @Autowired annotation
  7. Put in an empty test method just for the moment
  8. Add the Spring <beans> element (including the Camel Namespace) with an empty <camelContext> element to the Spring context, like this:
    Code Block
    xml
    xml
    
    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://www.springframework.org/schema/beans
                                   http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
                               http://activemq.apache.org/camel/schema/spring
                                   http://activemq.apache.org/camel/schema/spring/camel-spring-1.3.0.xsd">
    
        <camelContext id="camel" xmlns="http://activemq.apache.org/camel/schema/spring">
        </camelContext>
    </beans>
    

Your test class might look something like this:

  • src/test/java/org/apache/camel/tutorial/XMLInputTest.java
  • src/test/resources/XMLInputTest-context.xml (same as just above)

Test it by running mvn install and make sure there are no build errors.
