Using
You simply use the class component just as the Bean component but by specifying the fully qualified classname instead.
For example to use the MyFooBean you have to do as follows:

}} h3. Using You simply use the *class* component just as the [Bean] component but by specifying the fully qualified classname instead. For example to use the {{MyFooBean}} you have to do as follows: {code} from("direct:start").to("class:org.apache.camel.component.bean.MyFooBean").to("mock:result"); {code} You can also specify which method to invoke on the {{MyFooBean}}, for example {{hello}}: |

{code |
}
from("direct:start").to("class:org.apache.camel.component.bean.MyFooBean?method=hello").to("mock:result");

Setting properties on the created instance
In the endpoint uri you can specify properties to set on the created instance, for example if it has a setPrefix method:

Setting properties on the created instance In the endpoint uri you can specify properties to set on the created instance, for example if it has a {{setPrefix}} method: {code} from("direct:start") .to("class:org.apache.camel.component.bean.MyPrefixBean?prefix=Bye") .to("mock:result"); {code} And you can also use the {{#}} syntax to refer to properties to be looked up in the [Registry]. |
...
{code |
} from("direct:start") .to("class:org.apache.camel.component.bean.MyPrefixBean?cool=#foo") .to("mock:result"); {code} Which will lookup a bean from the [Registry] with the id {{foo}} and invoke the {{setCool}} method on the created instance of the {{MyPrefixBean}} class. |
