We are trying to use the java client library in our SpringBoot application to connect with Rustici Cloud. When we call any service using the client library, we are getting this error

 ERROR org.apache.cxf.jaxrs.utils.JAXRSUtils - No message body reader has been found for class com.rusticisoftware.cloud.v2.client.model.CourseListSchema, ContentType: application/json

In our application we are consuming some other services through CXF client. I can see that scormcloud-api-v2-client-java is using jersey2 as its java api client(instead of the default (okhttp-gson). Since our application is consuming some other services through CXF client, it seems like the scormcloud-api-v2-client-java library is picking up CXF Response implementation instead of the json implementation to read from the api.

To verify the issue, I created a separate test SpringBoot application just for testing scorm cloud via java client library. I worked fine as the application doesnt have any other functionality that uses cxf.

I also built custom-rustici-client-library from Swagger Codegen using your api specification. I didn't use jersey2 as the java api client. i.e. I went without specifying the library ( thus using the default option okhttp-gson) . I used the following using the config file for generating the client library.

{
    "apiPackage" : "api",
    "invokerPackage" : "com.rusticisoftware.cloud.v2.client",
    "apiPackage" : "com.rusticisoftware.cloud.v2.client.api",
    "modelPackage" : "com.rusticisoftware.cloud.v2.client.model",
    "groupId": "com.rusticisoftware.cloud.v2.client",
    "artifactId": "scormcloud-api-v2-client",
    "artifactId": "1.0.3"
} 

I was able to consume the rustici cloud api using this custom-rustici-client-library.

I have two questions.

1. Is there a reason to use jersey2 as the java api client library?
2. Can this client library be re-published using default client library(okhttp-gson) instead of jersey2 so that we dont have to maintain the client library ourselves?

As per the api documentation - https://rustici-docs.s3.amazonaws.com/engine/21.1.x/api/apiV2.html#/course/ImportCourseWithoutUpload,

importRequest can be set using
"referenceRequest": {
"url": "string",
"webPathToCourse": "string",
"mediaFileMetadata": {
"title": "string",
"description": "string",
"contentLanguage": "string",
"moveOn": "string",
"estimatedDuration": 0,
"activityType": "string",
"xAPIActivityId": "string",
"cmi5PublisherId": "string"
}
},

but, this option is missing from sdk.
SDK supports fetchRequest, mediaFileReferenceRequest and connectorReferenceRequest only.

Is it possible to add referenceRequest to the sdk ?
