I am trying to call class from a wso2 sequence However, I am getting this error:

 Error loading class : com.test.mediator.ChangeValue - Class not found java.lang.ClassNotFoundException: com.test.mediator.ChangeValue cannot be found by synapse-core_2.1.7.wso2v182

For a little better understanding calling class in sequence is as follows:

 <class name="com.test.mediator.ChangeValue"/>
<log level="custom">
    <property name="After CLASS" value="in Seq"/>
    <property expression="$ctx:NameN" name="NameClass"/>
</log>

For class, the class definition is as follows:

package com.test.mediator;

import org.apache.synapse.MessageContext; 
import org.apache.synapse.mediators.AbstractMediator;

public class ChangeValue extends AbstractMediator {

public boolean mediate(MessageContext context) { 
    // TODO Implement your mediation logic here 
    changeVal(context);
    return true;
}

public void changeVal(MessageContext context) {
    String Namem = (String) context.getProperty("NAMEE");
    String Namen = "Ali";
    context.setProperty("NameN", Namen);
  }
}

Any help why this error would be showing up would mean a lot please thanks

What's happening here is you haven't added the Class mediator to the MI run time. So runtime is unable to find the Class mediator. There are two ways to add a Class mediator to the MI runtime.

1. Build the Class Mediator Project using Maven and copy the Jar to <MI_HOME>/lib directory and restart the server.
2. Pack the ClassMediator into a Carbon Application and deploy it to MI. You can use this blog as a reference.
