Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'step1': Initialization of bean fa

Question

i'm creating an automatic process with Spring Batch, but when i'm creationg the XML File to define the configuration it's throwing me this error:

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'step1': Initialization of bean failed Caused by: org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'com.konecta.tpvsemselavon.batch.task.Pruebajaja$$EnhancerBySpringCGLIB$$630a5c43' to required type 'org.springframework.batch.core.step.tasklet.Tasklet' for property 'tasklet'; nested exception is java.lang.IllegalStateException: Cannot convert value of type 'com.konecta.tpvsemselavon.batch.task.Pruebajaja$$EnhancerBySpringCGLIB$$630a5c43' to required type 'org.springframework.batch.core.step.tasklet.Tasklet' for property 'tasklet': no matching editors or conversion strategy found

My XML file is like that:

<import resource="applicationContext.xml" />

<context:annotation-config />
<context:component-scan
    base-package="com.konecta.tpvsemselavon.batch" />

<!-- Aspecto de envio de correos ante errores inesperados -->

    <batch:step id="step1" next="stepFinal"> //seems it's failing here
        <batch:tasklet ref="prueba">

        </batch:tasklet>
    </batch:step>
    <batch:step id="stepFinal">
        <batch:tasklet ref="finalTasklet">
        </batch:tasklet>
    </batch:step>
</batch:job>

What can be the problem?
