Question

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:

This problem is known issue and various answer is already available in stackoverflow.

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.

Suggestion#2:

You can add jersy bundle jar file in your pom.xml file.

<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-bundle</artifactId>
    <version>1.19.3</version>
</dependency>

This may also can solve the issue sometimes.

Suggestion#3:

Check your entitiy contains @XmlRootElement annotations or not. If not, then please add it.

Suggestion#4:

jonbros suggested that instead of using the assembly plugin for maven use the shade plugin!

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.
