Third Party Library for GWT validation

[abdul]

I want to validate the gwt field like (Email,Text Length,Phone Number,Date & SSN,etc..) Is there any proven JS or Library Available for Validating this fields with GWT.

• I Can't use GWT Validation FrameworkorGWT Errai for my application since i am getting response as JSON not DTO.

• Even I tried Parsley JS(http://parsleyjs.org/ ) which is not possible (Reason:GWT have {key,value} pair to set the attribute but parsley have only value.)

  Any suggestion?

Are you not marshalling the response into a POJO?  GWT Validation can be done (with most validators, though not all) client-side.

Yes Chad,I can't use GWT Validation(my application response is in the JSON format not in POJO)..

The way you request your server doesn't matter...

The GWT Validation Framework allows you to test your fields in both front-end and back-end.

As soon as you test your fields, you will get an error list.

[Chad Vincent]

So you never convert the JSON to a POJO client side?  (GWT responses use GSON, a Google-modified JSON, and are converted to POJO post-receive.)

My best suggestion then is to just walk the JSON as a Map and use a custom validator interface...

Huh!?!?!?!

GWT-RPC uses its own serialization formats (plural: server-to-client is based on JS object literals –there's a patch to move to pure JSON, but it hasn't been merged yet IIRC– whereas client-to-server is completely custom; anyway, those are custom formats: https://drive.google.com/open?id=1eG0YocsYYbNAtivkLtcaiEE5IOF5u4LUol8-LL0TIKU&authuser=0 )

RequestFactory uses JSON, but with a custom structure; so let's call it a custom format as well.

GSON is an open-source Java library, by Google, for working with JSON; nothing to do with a "Google-modified JSON": https://github.com/google/gson

Huh.  It's been a few years since I was in the raw serialization bits.  I must've got things confused.

Actually, that serialization format looks like what I remember seeing of HL7.
