Since we're on a major migration process of this website, some component documents here are out of sync right now. In the meantime you may want to look at the asciidoc in the repository:


Camel supports the unified JSP and JSF Expression Language via the JUEL to allow an Expression or Predicate to be used in the DSL or Xml Configuration.

For example you could use EL inside a Message Filter in XML

  <from uri="seda:foo"/>
    <el>${ == 'bar'}</el>
    <to uri="seda:bar"/>

You could also use slightly different syntax, e.g. if the header name is not a valid identifier:

  <from uri="seda:foo"/>
    <el>${in.headers['My Header'] == 'bar'}</el>
    <to uri="seda:bar"/>

You could use EL to create an Predicate in a Message Filter or as an Expression for a Recipient List







the Exchange object



the message



the exchange.out message


You can use EL dot notation to invoke operations. If you for instance have a body that contains a POJO that has a getFamiliyName method then you can construct the syntax as follows:



To use EL in your camel routes you need to add the a dependency on camel-juel which implements the EL language.

If you use maven you could just add the following to your pom.xml, substituting the version number for the latest & greatest release (see the download page for the latest versions).


Otherwise you'll also need to include JUEL.
