Issue

I'm using Spring Rest API in server side and jersey API in client side.

I'm creating a screen where it will fetch last 5 customer redeem transaction.

From server side i'm returning list of RedeemTransactionDetails and accepting the same in client side.

I had debugged server side code it's returns the valid list, and in client side response code is 200 , whereas while getting entity i'm getting error from client side.

Server side:

    @RestController
    @RequestMapping("/rest/api")
    public class CustomerRestController {
            @Autowired private CustomerService customerService;

            @RequestMapping(value="/redeemTransactionList/{clientId}/{mobileNumber}/{numOfTransaction}" , method=RequestMethod.POST , produces = "application/json; charset=UTF-8")
            public @ResponseBody List<RedeemTransactionDetails> redeemTransaction(@PathVariable(value = "clientId") int clientId, @PathVariable(value = "mobileNumber") String mobileNumber , @PathVariable(value="numOfTransaction") int numOfTransaction) {
            LOG.debug("We are in redeemTransaction method for user {} " , clientId);
            List<RedeemTransactionDetails> redeemList = null ;
            try {
                redeemList =  customerService.redeemTransactionList(clientId, mobileNumber,numOfTransaction);

            } catch (Exception e) {
                LOG.debug("Excption while fetching redeemTransaction ");
            }
            return  redeemList;
        }
    }

Client Side :

public List<RedeemTransactionDetails> getRedeemTransactions(String mobileNumber, String clientId, String numberOfTransaction) {
    log.debug("inside authenticate() ");
    List<RedeemTransactionDetails> result = null; 
    try{
        webResource = client.resource(uri + "/redeemTransactionList").path(clientId).path(mobileNumber).path(numberOfTransaction) ;
        ClientResponse response = webResource.type(MediaType.APPLICATION_JSON).post(ClientResponse.class);
        if (response.getStatus() != 200) {
            log.debug("response.getStatus() : " +  response.getStatus() );  
            throw new RuntimeException("Failed : HTTP error code : " + response.getStatus());
         } 
        response.getType() ;
        result = (List<RedeemTransactionDetails>) response.getEntity(RedeemTransactionDetails.class);
        log.debug("user Details " + result);
    }
    catch(Exception e){
        log.debug(e);
    }
    return result ;
}
}

NOTE: I had used the following dependencies in pom xml file

<dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-json</artifactId>
        <version>1.19.3</version>
    </dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.8.6</version>
</dependency>

EDIT:

Solution

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.
