<exceptionMessage>[Ljava.lang.String; incompatible with java.lang.String</exceptionMessage>

Question

I am taking the request parameters from the front-end web app and displaying the result accordingly.

Map<String,Object> requestparms

testObj.setUserId(requestparms.get("userId") == null ? null :requestparms.get("userId").toString());

When I test using the restClient I get the following error :

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<error incidentId="22854566" correlationId="922f4150-4636-4b94-8ac6-71f8ed1935c1">
    <exceptionMessage>[Ljava.lang.String; incompatible with java.lang.String</exceptionMessage>
</error>

I tried

String userId = String.valueOf(requestparms.get("userId"));
System.out.println("The value of variable is " +userId);

Still the same error.

Can you someone please with help information related to it ?

Thank you in advance, Lucky

Try typecasting as per below

Map<String,Object> requestparms

testObj.setUserId(requestparms.get("userId") == null ? null:(String)requestparms.get("userId").toString());

Otherwise, may be MAP is not understood by REST client?? SOAP doesn't know how to parse MAP so i believe REST is same....

If this is the issue then try using JSON. It definitely works...
