Jeff, you might be interesting in watching this new project:
https://github.com/fge/json-schema-validator

This new project was originally based on Nico’s validator but has been developed further and supports (most of) the latest draft.

Hi,
Great effort to explain stress testing. Can you help me with this data

Aggregate report

my web page (sample) 491 (samples) 15620 (averge) 10825 (median) 24724 (90% line) 1103 (min) 193165(max) 2.1771325700806115 (throuput) 102.71376692709488 (KB/sec) 0.026476578411405296 (Errors)

I want to calculate how many users can concurrently access my “my web page ” web page? Each sample returns with 47203 bytes (46.09668 kb ) of response.

This is my case. Please help me to find out concurrent users.

Here 0.2% error occurred and I get following error message

I see the same thing with card.json test. It appears, however, that the latest version of the Core Schema Definition has changed fairly dramatically. From the most recent changes log of draft-zyp-json-schema-03:

* Replaced “optional” attribute with “required” attribute.
* Replaced “maximumCanEqual” attribute with “exclusiveMaximum”
attribute.
* Replaced “minimumCanEqual” attribute with “exclusiveMinimum”
attribute.
* Replaced “requires” attribute with “dependencies” attribute.

…among others. Is anyone working on updates?

Comment on JSON Schema: specifying and validating JSON data structures by Suresh

Suresh — Mon, 21 Feb 2011 11:42:03 +0000

hi,
Here is my requirement,
1) Validate my client JSON request at the server side.
2) Convert the JSON request to an Java object.

What validation method is better in terms of performace,
1) Define json schema and validate the json request against the schema, or
2) First convert json request to java object and have a validate method in the java class and validate it.

Will approach 2 have better performance? Have any one encountered this requirement?
