Exception Reason

As Camel support multiple type of routing and it required dependcies for use it. Here we are using SMTP routing to send email on came of defined routing but it required to add camel dependency for SMTP email in pom.xml.

Solution

As exception stack trace clearly explained, it required missing camel component jar. In case of SMTP you need to add below jar for sending Email through camel SMTP route.

           <dependency>
            <groupId>org.apache.camel</groupId>
            <artifactId>camel-core</artifactId>
            <version>${camel.version}</version>
        </dependency>
        <dependency>
            <groupId>org.apache.camel</groupId>
            <artifactId>camel-mail</artifactId>
            <version>${camel.version}</version>
        </dependency>
