   So I have a route like:
   
   ```java
   import org.apache.camel.PropertyInject;
   import org.apache.camel.builder.RouteBuilder;
   
   public class Sample extends RouteBuilder {
     @PropertyInject("my.url")
     String url;
   
     @Override
     public void configure() throws Exception {
       from("timer:tick")
         .setBody().constant(url)
         .log("${body}");
     }
   }
   ```
   
   The I do run it with:
   
       kamel run --dev -p my.url=test examples/Sample.java
   
   And what I see in my toute is:
   
   ```

   ```
   
   So the properties binding works. I think your issue is that the connection factory is instantiated at class constructions, you should move it to the `configure` method as the injection happens after the class has been constructed, before that the url is null
