BeanShell is a Java-based scripting language that allows quick parsing of
object. The BeanShell support is part of the camel-script module.
![[Important]](imagesdb/important.gif) | Important |
|---|---|
You must use BeanShell 2.0b5 or greater. |
To use BeanShell in your routes you need to add a dependency on
camel-script to your project as shown in
Example 2.1.
Example 2.1. Adding the camel-script dependency
<!-- Maven POM File -->
<properties>
<camel-version>2.7.1-fuse-00-27</camel-version>
...
</properties>
<dependencies>
...
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-script</artifactId>
<version>${camel-version}</version>
</dependency>
...
</dependencies>Table 2.1 lists the built-in attributes that are accessible when using BeanShell.
Table 2.1. BeanShell attributes
| Attribute | Type | Value |

context | org.apache.camel.CamelContext | The Camel Context |
exchange | org.apache.camel.Exchange | The current Exchange |
request | org.apache.camel.Message | The IN message |
response | org.apache.camel.Message | The OUT message |
The attributes all set at ENGINE_SCOPE.
Example 2.2 shows two routes that use BeanShell scripts.
Example 2.2. Routes using BeanShell
<camelContext>
<route>
<from uri=""mock:mock0" />
<filter>
<language language="beanshell">request.getHeaders().get("Foo") == null</language>
<to uri="mock:mock1" />
</filter>
</route>
<route>
<from uri="direct:in"/>
<setHeader headerName="firstName">
<expression language="beanshell">user.firstName</expression>
