A JSON Schema validation implementation in pure Java, which aims for correctness and performance, in that order

Hi,

I'm not having any issues with SchemaNode and validation, but I would like a way to print my SchemaNode with $ref resolved. An example of this is on http://www.jsonschema.net/ where they can pretty print the Json Schema in JSON format.

Is there any way to do this with json-schema-validator's SchemaNode or SchemaTree?

Thanks!

As far as i can see, all error messages are stored as enumerations and cannot be modified via any configuration? Is this correct?

For example, changing the message from 'input is not a valid email address' to 'The value you have entered is not a valid email address'.

Thanks!

Hi,

Firstly, thanks for creating this library.

I'm trying to validate some JSON data against a schema I have. I am getting the "a parent schema's id must be absolute" error.

If I make the schema id absolute, such as using a "http://" URI, my problem then becomes that I am using offline tests.

I now want to be able to get hold of the the URIManager and override the "http" downloader, in order to resolve the URIs myself to local files, but all the fields I seem to need to access are private and final.

Can you offer any advice please?

Thanks.

Issue

I have been working to make our Schema project more robust and allow it to be used offline and online. Your validator is the best, but I can't seem to get it tor validate a linked relative uri schema.

I have looked at your "Example 5" and have also written two tests against our schema as a test. The issue it that I would like set the namespace depending on how I want to use the schema files. It would be really nice to be able to checkout the whole schema repository and set the namespace to a specific file, or if I wanted to set the namespace to be on the public website, I could do that too.

Tests

Here is the test I wrote: https://github.com/spidasoftware/schema/blob/cee/utils/test/groovy/com/spidasoftware/schema/validation/ConceptualSchemaTest.groovy

Here is the base schema file: https://github.com/spidasoftware/schema/blob/cee/v1/spidacalc/calc/point.schema that references two other files.

Am I doing something totally wrong, or is this a bug?

Lastest version: 1.4.1 Error explanation:

• Define a schema1 that is an extension from draftv3 and that add a new property, 'indexed', that is declared as boolean.
• Define an new schema using schema1, schema2. The value for property 'indexed' is 111.
• The validator should give an error, since for property 'indexed' only a boolean value should be allowed.

Code:

import java.io.File;
import java.io.IOException;

import com.fasterxml.jackson.databind.JsonNode;
import org.eel.kitchen.jsonschema.main.JsonSchema;
import org.eel.kitchen.jsonschema.main.JsonSchemaFactory;
import org.eel.kitchen.jsonschema.report.ValidationReport;
import org.eel.kitchen.jsonschema.util.JsonLoader;

public class JsonSchemaTest {

  public static void main(String[] args) {
    try {
        JsonNode draftv3 = JsonLoader.fromResource("/draftv3/schema");
        JsonNode schema1 = JsonLoader.fromFile(new File("schema1.json"));
        JsonNode schema2 = JsonLoader.fromFile(new File("schema2.json"));

        ValidationReport report;

        JsonSchemaFactory factory = JsonSchemaFactory.defaultFactory();
        JsonSchema draftv3Schema = factory.fromSchema(draftv3);
        report = draftv3Schema.validate(schema1);
        if (!report.isSuccess())
            System.out.println("Schema1: " + report.asJsonObject());

        JsonSchema schema1Schema = factory.fromSchema(schema1);
        report = schema1Schema.validate(schema2);
        if (!report.isSuccess())
            System.out.println("Schema2: " + report.asJsonObject());
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
  }
}

The schema1.json file is

{
 "extends" : {
    "$ref" : "http://json-schema.org/draft-03/schema#"
   },
  "properties" : {
  "indexed" : {
     "type" :  "boolean",
     "default" : false
   }
 }
}

The schema2.json is

{
 "type" : "object",
 "properties" : {
   "from" :  {
      "type" : "string",
      "required" : true,
      "indexed" : 111
   }
  }
}

JsonSchemaFactoryBuilder factoryBuilder = JsonSchemaFactory.newBuilder();

throws an exception " android zygoteinit$methodandargscaller "

Hi,

can the library fge/json-schema-validator generate Java classes from a JSON Schema? otherwise, is it planned to add this feature some time soon?

if not, can you suggest a solution? I've read about "jsonschema2pojo". is that a good solution?

best regards, David

I was performing some tests of json-schema-validator and found the following behavior. I defined the following schema

{ "extends":{"$ref" : "http://json-schema.org/draft-03/schema#"}, "properties":{ "indexed":{"type": "boolean", "default":false} } }

and after that I try the validate the next schema.

{ "type" : "object", "properties" : { "from" : { "type" : "string", "indexed":111 } } }

It should give an error, since Indexed is a boolean property and not a integer. And it don't. The schema is validated and is considered correct.

Hi,

I am using json-schema-validation library in WSO2 ESB. I copied all the required jars in WSO2ESB_HOME/repository/components/lib and when I run my code, it always fail in the above call SchemaVersion.java calls JsonLoader.fromResource(resource) (line no 69). I am using json-schema-validation version 2.2.0

Any help in this regards will be helpful. Let me know if I need to provide any other information.

Regards, Ritesh

as far as I understand - this should be a valid schema:

{ "type" : "array", "items" : { "type" : [ { "type" : "object", "properties" : { "name" : { "type" : "string" }}}, { "type" : "object", "properties" : { "price" : { "type" : "number" } } } ] } }

but it comes out as invalid in the schema validator is this a bug? or it's actually invalid? thanks!

It's different to locate the error in current Report format as follows for large JSON file. Is it possible to add line number into Report to denote which line is the pointer(schema or instance)?

com.github.fge.jsonschema.report.ListProcessingReport: failure--- BEGIN MESSAGES ---error: instance type does not match any allowed primitive type level: "error" schema: {"loadingURI":"#","pointer":"/properties/version"} instance: {"pointer":"/version"} domain: "validation" keyword: "type" expected: ["integer"] found: "number" --- END MESSAGES ---

Thanks, Hai

Hi, we noticed this when bumping to json-schema-validator 2.2.14, we use duplicate-finder-maven-plugin to track jar hell (we build a fat jar) and it appears that the draftv4/schema resource is slightly different in these two projects:

like this
