How can I validate a JSON string against a schema programmatically?

Question

Are there simple libraries out there (.NET and Java) that are able to validate a JSON string given a schema definition?

It should work similar to how XML can be validated using XSD.

EDIT: I need .NET and Java libraries. Thanks to darin for the .NET link!

Answer 1

Here You can find some Java classes which might helpful when working with JSON.

When syntax of Your JSON String is incorrect instance of JSONException will be thrown - this is the simplest way to check correctness, I think. JSONTokener is the class You have to use to parse. It has a constructor which takes java.lang.String as a parameter.

Edit: Sorry, I misunderstood a little. Probably JSON Tools is the library You are looking for. It provides validation using a JSON schema.

Answer 2

For .NET you could use Json.NET which supports schema validation.
