-The following example shows how to use the SetBody EIP
+=== Using Set Body EIP
+
+You can use a xref:setBody-eip.adoc[Set Body] which uses an
+xref:latest@manual:ROOT:expression.adoc[Expression] to do the transformation:
+
+In the example below we prepend Hello to the message body using the
+xref:components:languages:simple-language.adoc[Simple] language:
[source,java]
----
-RouteBuilder builder = new RouteBuilder() {
- public void configure() {
- from("direct:a")
- .setBody(constant("test"))
- .to("direct:b");
- }
-};
+from("direct:cheese")

-<camelContext xmlns="http://camel.apache.org/schema/spring";>
- <route>
- <from uri="direct:a"/>
- <setBody><constant>test</constant></setBody>

+=== What is the difference between Transform and Set Body
+
+The Transform EIP always sets the result on the OUT message body.
+
+Set Body sets the result accordingly to the
xref:latest@manual:ROOT:exchange-pattern.adoc[Exchange Pattern]
+on the `Exchange`.
