javax.json module:

RFC8259 describes the JSON data model and interchange format, which is widely used in application-level protocols including RESTful APIs. It is common for applications to request resources via the HTTP POST method, with JSON entities. However, POST is suboptimal for requests which do not modify a resource's state. JSON→URL defines a text format for the JSON data model suitable for use within a URL/URI.

The core library defines a generic JSON->URL parser and includes an implementation based Java SE data types (e.g. java.util.Map, java.util.List, etc). There are two additional modules, distributed as separate artifacts, which implement a parser based on JSR-374 and Douglas Crockford's Java API.

Java SE API example:

<dependencies>
  <dependency>
    <groupId>org.jsonurl</groupId>
    <artifactId>jsonurl-core</artifactId>
    <version>${jsonurl.version}</version>
  </dependency>
</dependencies>

import org.jsonurl.JavaValueParser;

JavaValueParser p = new JavaValueParser();
Map obj = p.parseObject( "(Hello:World!)" );
System.out.println(obj.get("Hello")) // World!

Json.org example:

<dependencies>
  <dependency>
    <groupId>org.jsonurl</groupId>
    <artifactId>jsonurl-jsonorg</artifactId>
    <version>${jsonurl.version}</version>
  </dependency>
</dependencies>

import org.jsonurl.jsonorg.JsonUrlParser;

JsonUrlParser p = new JsonUrlParser();
JSONObject obj = p.parseObject( "(Hello:World!)" );
System.out.println(obj.get("Hello")) // World!

JSR-374 example:

<dependencies>
  <dependency>
    <groupId>org.jsonurl</groupId>
    <artifactId>jsonurl-jsr374</artifactId>
    <version>${jsonurl.version}</version>
  </dependency>
  <dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>javax.json</artifactId>
    <version>${javax.json.version}</version>
  </dependency>
</dependencies>

import org.jsonurl.jsonp.JsonUrlParser;

JsonUrlParser p = new JsonUrlParser();
JsonObject obj = p.parseObject( "(Hello:World!)" );
System.out.println(obj.get("Hello")) // World!

The parser is designed to parse untrusted input. It supports limits on the number of parsed values and depth of nested arrays or objects. When the limit is exceeded a LimitException is thrown. Sane limit values are set by default.
