-The SetProperty EIP allows you to set a property on your exchange.
+The SetProperty EIP is used for setting a
xref:latest@manual:ROOT:exchange.adoc[Exchange] property.

+NOTE: An `Exchange` property is a key/value set as a `Map` on the
`org.apache.camel.Exchange` instance.
+This is *not* for setting

-The following example shows how to use the SetProperty EIP
+The following example shows how to set a property on the exchange in a Camel
route:
[source,java]
----
-RouteBuilder builder = new RouteBuilder() {
- public void configure() {
- from("direct:a")
- .setProperty("myProperty", constant("test"))
- .to("direct:b");
- }
-};
+from("direct:a")
+ .setProperty("myProperty", constant("test"))
+ .to("direct:b");
----
-
And the same example using XML:
[source,xml]
----
-<camelContext xmlns="http://camel.apache.org/schema/spring";>
- <route>
- <from uri="direct:a"/>
- <setProperty name="myProperty">
- <constant>test</constant>
- </setProperty>
- <to uri="direct:b"/>
- </route>
-</camelContext>
+<route>
+ <from uri="direct:a"/>
+ <setProperty name="myProperty">
+ <constant>test</constant>
+ </setProperty>
+ <to uri="direct:b"/>
+</route>
+----
+
+=== Setting an exchange property from another exchange property
+
+You can also set an exchange property with the value from another exchange
property.
+
+In the example we set the exchange property foo with the value from an
existing exchange property named bar.
+
+[source,java]
+----
+from("direct:a")
+ .setProperty("foo", exchangeProperty("bar"))
+ .to("direct:b");
+----
+
+And in XML:
+
+[source,xml]
+----
+<route>
+ <from uri="direct:a"/>
+ <setProperty name="foo">
+ <exchangeProperty>bar</exchangeProperty>
+ </setProperty>
+ <to uri="direct:b"/>
+</route>
+----
+
+=== Setting an exchange property with the current message body
+
+It is of course also possible to set an exchange property with a value
+from anything on the `Exchange` such as the message body:
+
+[source,java]
+----
+from("direct:a")
+ .setProperty("myBody", body())
+ .to("direct:b");
+----
+
+And in XML we use the xref:components:languages:simple-language.adoc[Simple]
language
+to refer to the message body:
+
+[source,xml]
+----
+<route>
+ <from uri="direct:a"/>
+ <setProperty name="myBody">
+ <simple>${body}</simple>
+ </setProperty>
+ <to uri="direct:b"/>
+</route>
