BeanShell is a Java-based scripting language that allows quick parsing of
object. The BeanShell support is part of the camel-script module.
![]() | 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 1, “Adding the camel-script dependency”.
Example 1. Adding the camel-script dependency
<!-- Maven POM File -->
<properties>
<camel-version>2.8.0-fuse-00-05</camel-version>
...
</properties>
<dependencies>
...
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-script</artifactId>
<version>${camel-version}</version>
</dependency>
...
</dependencies>Table 2, “BeanShell attributes” lists the built-in attributes that are accessible when using BeanShell.
Table 2. 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, “Routes using BeanShell” shows two routes that use BeanShell scripts.
Example 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>
</setHeader>
<to uri="seda:users"/>
</route>
</camelContext>
