Now I am suggesting you to follow some suggestions to solve your issue.

Suggestion#1:

You can add genson jar file by using the following dependency in your pom.xml file

<dependency>
    <groupId>com.owlike</groupId>
    <artifactId>genson</artifactId>
    <version>1.4</version>
</dependency>

Documentation can be found at: https://owlike.github.io/genson/

Then clean your project and build and then run.

The error indicates JerseyClient may not have been configured properly to scan Provider packages. Check your web.xml if 'jersey.config.server.provider.packages' property is configured to include 'com.prom.via.rest.dto' package that contains your JAXB classes.

<servlet-name>Jersey REST Service</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
     <!-- Register resources and providers under com.prom.via.rest.dto package. -->
    <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>com.prom.via.rest.dto</param-value>
    </init-param>
</servlet>

Also, as SkyWalker indicated check if RedeemTransactionDetails is annotated with @XmlRootElement annotation or not.
