How to convert XSD to JSON schema directly in Java

Question

can anybody suggest how to convert XSD schema to JSON schema using Java?

I have tried so many ways, almost all the ways generating class files using com.fasterxml.jackson libraries and then converting it to JSON which is not possible in my case.

here are the links I have tried

Follow below steps to directly transform XSD into JSON Schema using Jsonix library

1. Download jsonix schema compiler from here

   The downloaded jar name would be something like below based on downloaded version
   jsonix-schema-compiler-full-2.3.9.jar

2. Open command prompt or linux shell and navigate to the above jar directory.

3. Execute below command from this directory
   java -jar jsonix-schema-compiler-full-2.3.9.jar -generateJsonSchema -p FOOD schemas/food.xsd
   Note: in above command schemas/food.xsd is the relative path of XSD schema file

4. Above step will generate two files in the current directory
   a. schema file (FOOD.jsonschema)
   b. mapping file (FOOD.js)

5. The schema file with .jsonschema extenstion is the desired equivalent JSON Schema.
