JsonNode schema = JsonLoader.fromResource("/jsonschema.json"); // correct? or correct me
JsonNode data = JsonLoader.fromString(jsonData);
ProcessingReport report = validator.validate(schema, data);

This may help you
Place jsonschema file on project root directory or in resource and read schema using normal file read and store it in variable say str

     booleab isValidRequest=false;
     String     requestData; // data to validate
     String str; //schema 

            JsonNode requestDataJsonNode = com.github.fge.jackson.JsonLoader.fromString(requestData);       
            final JsonNode schemaNode = JsonLoader.fromString(str);
    //      final JsonNode schemaNode=JsonLoader.fromResource("jsonschema.json"); for your query
            final JsonSchemaFactory factory = JsonSchemaFactory.byDefault();
            JsonValidator validator = factory.getValidator();        
            ProcessingReport processingReport=  validator.validate(schemaNode, requestDataJsonNode); 

            } catch (Exception e) {
