    Question Validate JSON according XSD schema

    Hi,

    Some site have REST API that return responses in two formats : xml and JSON .
    Currently I finished basic checks for xml responses of this API .

    Idea was simple - validate xml response using existing xsd schema that clear define what should be inside . I use Jersey (— Project Kenai ) for "speaking" with API and SAX to validate responses.

    Now I need to do the same for JSON format . First big problem here is that I don't have JSON Schema to validate JSON response . So only way that I see is unmarshall JSON response to POJO hierarchy and then validate it against xsd that I have . But this way also raise up hard questions : I can't find Java classes that allow me to do this automatically . Also I can't find classes that allow me to work with xsd in low level - I mean not just general "tell me if this xml is valid according this xsd" but "tell me if this tag can have such children with such types".

    Any ideas , directions or just thoughts are welcome. Maybe somebody can suggest totally different way ? Or somebody can suggest classes that allow to work with xsd on low level ?

    Default Re: Validate JSON according XSD schema

    Hi All,

    I am currently working on creating a new Json schema which would help a user to sign into an application.

    There are two different ways of logging in:
    1. Username / password
    2. email /password

    Anyone of the above combination given by the user, he should be able to login. I have written two different schemas for this. The schemas goes this way

    1. Username /password schema:
    -------------------------------------

    {
    "required": true,
    "type": "object",
    "additionalProperties": false,
    "properties": {
    "type": {
    "required": true,
    "type": "string",
    },
    "username": {
    "required": true,
    "type": "string",
    },
    "password": {
    "required": true,
    "type": "string",
    }
    }
    }

    2. email /password schema:
    --------------------------------

    {
    "required": true,
    "type": "object",
    "additionalProperties": false,
    "properties": {
    "type": {
    "required": true,
    "type": "string",
    },
    "email": {
    "required": true,
    "type": "string",
    },
    "password": {
    "required": true,
    "type": "string",
    }
    }
    }

    Is there a way to combine these two schemas and match the input given by the user.
    something like: If the type=='email' then switch to email and password combination else switch to username password combination?

    any help would be greatly appreciated.

    Thanks,
    Pradeep
