java.lang.ClassNotFoundException: de.odysseus.el.ExpressionFactoryImpl

Question

My application is using apache camel along with spring. I am getting exception in EL expression shown below in camel-context.xml in.body is request object and it has method getParam().

<filter>
    <el>${(in.body.getParam != null) and (in.body.getParam[validate] == 'Y')}</el>
    <log message="validating...${in.body.getParam[errorResponse]}" />
    <filter>
        <method ref="validationExecutor" method="execute" ></method>
        <setBody><simple>${in.body.getParam[errorResponse]}</simple></setBody>
        <stop />
    </filter>
</filter>

I have added dependency as

<dependency>
            <groupId>org.apache.camel</groupId>
            <artifactId>camel-juel</artifactId>
            <version>2.10.0</version>
</dependency>

still i'm getting exception java.lang.ClassNotFoundException: de.odysseus.el.ExpressionFactoryImpl

i have further looked into classes loaded by using vm arg -verbose:class I found that there are other jars loaded which are related to EL

apache-tomcat-7.0.62/lib/el-api.jar
geronimo-el_1.0_spec-1.0.1.jar

I have not specified them in pom, but still these jars got added. how can i remove them?
