So here are some advices about which one to use: the validator collects every schema violations (instead of failing immediately on the first one).Jackson, as of date, does not provide support for validating JSON data against a JSON schema.Hence, you cannot use Jackson for validation purposes.*The maximum size limit for file upload is 2 megabytes.This tutorial shows how to validate JSON against Schema in Java.The The main method shown below shows the logic to validate JSON using the utility class presented further below in this tutorial.

Note that we are loading the schema and the JSON documents from files.

The validator will report fatal errors, non-fatal errors and warnings.

If the XSD is publicly available using HTTP and referenced through a "schema Location" or "no Namespace Schema Location", then the validator will pick it up and it doesn't need to be specified/uploaded.

Create an XSDBuilder object and invoke the build(Input Source) method of the XSDBuilder object to obtain an XMLSchema object.

The Input Source object is created with an Input Stream object created from the example XML schema document,

As discussed before, we have used an Input Source object because most SAX implementations are Input Source based.
