JSON in Java [package org.json]
===============================
[![Maven Central](https://img.shields.io/maven-central/v/org.json/json.svg)](https://mvnrepository.com/artifact/org.json/json)
JSON is a light-weight, language independent, data interchange format.
See http://www.JSON.org/
The files in this package implement JSON encoders/decoders in Java.
It also includes the capability to convert between JSON and XML, HTTP
headers, Cookies, and CDL.
This is a reference implementation. There is a large number of JSON packages
in Java. Perhaps someday the Java community will standardize on one. Until
then, choose carefully.
The license includes this restriction: "The software shall be used for good,
not evil." If your conscience cannot live with that, then choose a different
package.
The package compiles on Java 1.6-1.8.
**JSONObject.java**: The `JSONObject` can parse text from a `String` or a `JSONTokener`
to produce a map-like object. The object provides methods for manipulating its
contents, and for producing a JSON compliant object serialization.
**JSONArray.java**: The `JSONArray` can parse text from a String or a `JSONTokener`
to produce a vector-like object. The object provides methods for manipulating
its contents, and for producing a JSON compliant array serialization.
**JSONTokener.java**: The `JSONTokener` breaks a text into a sequence of individual
tokens. It can be constructed from a `String`, `Reader`, or `InputStream`.
**JSONException.java**: The `JSONException` is the standard exception type thrown
by this package.
**JSONPointer.java**: Implementation of
[JSON Pointer (RFC 6901)](https://tools.ietf.org/html/rfc6901). Supports
JSON Pointers both in the form of string representation and URI fragment
representation.
**JSONPropertyIgnore.java**: Annotation class that can be used on Java Bean getter methods.
When used on a bean method that would normally be serialized into a `JSONObject`, it
overrides the getter-to-key-name logic and forces the property to be excluded from the
resulting `JSONObject`.
**JSONPropertyName.java**: Annotation class that can be used on Java Bean getter methods.
When used on a bean method that would normally be serialized into a `JSONObject`, it
overrides the getter-to-key-name logic and uses the value of the annotation. The Bean
processor will look through the class hierarchy. This means you can use the annotation on
a base class or interface and the value of the annotation will be used even if the getter
is overridden in a child class.
**JSONString.java**: The `JSONString` interface requires a `toJSONString` method,
allowing an object to provide its own serialization.
**JSONStringer.java**: The `JSONStringer` provides a convenient facility for
building JSON strings.
**JSONWriter.java**: The `JSONWriter` provides a convenient facility for building
JSON text through a writer.
**CDL.java**: `CDL` provides support for converting between JSON and comma
delimited lists.
**Cookie.java**: `Cookie` provides support for converting between JSON and cookies.
**CookieList.java**: `CookieList` provides support for converting between JSON and
cookie lists.
**HTTP.java**: `HTTP` provides support for converting between JSON and HTTP headers.
**HTTPTokener.java**: `HTTPTokener` extends `JSONTokener` for parsing HTTP headers.
**XML.java**: `XML` provides support for converting between JSON and XML.
**JSONML.java**: `JSONML` provides support for converting between JSONML and XML.
**XMLTokener.java**: `XMLTokener` extends `JSONTokener` for parsing XML text.
Unit tests are maintained in a separate project. Contributing developers can test
JSON-java pull requests with the code in this project:
https://github.com/stleary/JSON-Java-unit-test
Numeric types in this package comply with
[ECMA-404: The JSON Data Interchange Format](http://www.ecma-international.org/publications/files/ECMA-ST/ECMA-404.pdf) and
[RFC 7159: The JavaScript Object Notation (JSON) Data Interchange Format](https://tools.ietf.org/html/rfc7159#section-6).
This package fully supports `Integer`, `Long`, and `Double` Java types. Partial support
for `BigInteger` and `BigDecimal` values in `JSONObject` and `JSONArray` objects is provided
in the form of `get()`, `opt()`, and `put()` API methods.
Although 1.6 compatibility is currently supported, it is not a project goal and may be
removed in some future release.
In compliance with RFC7159 page 10 section 9, the parser is more lax with what is valid
JSON than the Generator. For Example, the tab character (U+0009) is allowed when reading
JSON Text strings, but when output by the Generator, tab is properly converted to \t in
the string. Other instances may occur where reading invalid JSON text does not cause an
error to be generated. Malformed JSON Texts such as missing end " (quote) on strings or
invalid number formats (1.2e6.3) will cause errors as such documents can not be read
reliably.

* A JSONArray is an ordered sequence of values. Its external text form is a
* string wrapped in square brackets with commas separating the values. The
* internal form is an object having <code>get</code> and <code>opt</code>
* methods for accessing the values by index, and <code>put</code> methods for
* adding or replacing values. The values can be any of these types:
* <code>Boolean</code>, <code>JSONArray</code>, <code>JSONObject</code>,
* <code>Number</code>, <code>String</code>, or the
* <code>JSONObject.NULL object</code>.
* <p>
* The constructor can convert a JSON text into a Java object. The
* <code>toString</code> method converts to JSON text.
* <p>
* A <code>get</code> method returns a value if one can be found, and throws an
* exception if one cannot be found. An <code>opt</code> method returns a
* default value instead of throwing an exception, and so is useful for
* obtaining optional values.
* <p>
* The generic <code>get()</code> and <code>opt()</code> methods return an
* object which you can cast or query for type. There are also typed
* <code>get</code> and <code>opt</code> methods that do type checking and type
* coercion for you.
* <p>
* The texts produced by the <code>toString</code> methods strictly conform to
* JSON syntax rules. The constructors are more forgiving in the texts they will
* accept:
* <ul>
* <li>An extra <code>,</code>&nbsp;<small>(comma)</small> may appear just
* before the closing bracket.</li>
* <li>The <code>null</code> value will be inserted when there is <code>,</code>
* &nbsp;<small>(comma)</small> elision.</li>
* <li>Strings may be quoted with <code>'</code>&nbsp;<small>(single
* quote)</small>.</li>
* <li>Strings do not need to be quoted at all if they do not begin with a quote
* or single quote, and if they do not contain leading or trailing spaces, and
* if they do not contain any of these characters:
* <code>{ } [ ] / \ : , #</code> and if they do not look like numbers and
* if they are not the reserved words <code>true</code>, <code>false</code>, or
* <code>null</code>.</li>

/**
* A JSONObject is an unordered collection of name/value pairs. Its external
* form is a string wrapped in curly braces with colons between the names and
* values, and commas between the values and names. The internal form is an
* object having <code>get</code> and <code>opt</code> methods for accessing
* the values by name, and <code>put</code> methods for adding or replacing
* values by name. The values can be any of these types: <code>Boolean</code>,
* <code>JSONArray</code>, <code>JSONObject</code>, <code>Number</code>,
* <code>String</code>, or the <code>JSONObject.NULL</code> object. A
* JSONObject constructor can be used to convert an external form JSON text
* into an internal form whose values can be retrieved with the
* <code>get</code> and <code>opt</code> methods, or to convert values into a
* JSON text using the <code>put</code> and <code>toString</code> methods. A
* <code>get</code> method returns a value if one can be found, and throws an
* exception if one cannot be found. An <code>opt</code> method returns a
* default value instead of throwing an exception, and so is useful for
* obtaining optional values.
* <p>
* The generic <code>get()</code> and <code>opt()</code> methods return an
* object, which you can cast or query for type. There are also typed
* <code>get</code> and <code>opt</code> methods that do type checking and type
* coercion for you. The opt methods differ from the get methods in that they
* do not throw. Instead, they return a specified value, such as null.
* <p>
* The <code>put</code> methods add or replace values in an object. For
* example,
*
* <pre>
* myString = new JSONObject()
* .put(&quot;JSON&quot;, &quot;Hello, World!&quot;).toString();
* </pre>
*
* produces the string <code>{"JSON": "Hello, World"}</code>.
* <p>
* The texts produced by the <code>toString</code> methods strictly conform to
* the JSON syntax rules. The constructors are more forgiving in the texts they
* will accept:
* <ul>
* <li>An extra <code>,</code>&nbsp;<small>(comma)</small> may appear just
* before the closing brace.</li>
* <li>Strings may be quoted with <code>'</code>&nbsp;<small>(single
* quote)</small>.</li>
* <li>Strings do not need to be quoted at all if they do not begin with a
* quote or single quote, and if they do not contain leading or trailing
* spaces, and if they do not contain any of these characters:
* <code>{ } [ ] / \ : , #</code> and if they do not look like numbers and
* if they are not the reserved words <code>true</code>, <code>false</code>,
* or <code>null</code>.</li>
* </ul>

/**
* Construct a JSONObject from an Object using bean getters. It reflects on
* all of the public methods of the object. For each of the methods with no
* parameters and a name starting with <code>"get"</code> or
* <code>"is"</code> followed by an uppercase letter, the method is invoked,
* and a key and the value returned from the getter method are put into the
* new JSONObject.
* <p>
* The key is formed by removing the <code>"get"</code> or <code>"is"</code>
* prefix. If the second remaining character is not upper case, then the
* first character is converted to lower case.
* <p>
* Methods that are <code>static</code>, return <code>void</code>,
* have parameters, or are "bridge" methods, are ignored.
* <p>
* For example, if an object has a method named <code>"getName"</code>, and
* if the result of calling <code>object.getName()</code> is
* <code>"Larry Fine"</code>, then the JSONObject will contain
* <code>"name": "Larry Fine"</code>.
* <p>
* The {@link JSONPropertyName} annotation can be used on a bean getter to
* override key name used in the JSONObject. For example, using the object
* above with the <code>getName</code> method, if we annotated it with:
* <pre>
* &#64;JSONPropertyName("FullName")
* public String getName() { return this.name; }
* </pre>
* The resulting JSON object would contain <code>"FullName": "Larry Fine"</code>
* <p>
* Similarly, the {@link JSONPropertyName} annotation can be used on non-
* <code>get</code> and <code>is</code> methods. We can also override key
* name used in the JSONObject as seen below even though the field would normally
* be ignored:
* <pre>
* &#64;JSONPropertyName("FullName")
* public String fullName() { return this.name; }
* </pre>
* The resulting JSON object would contain <code>"FullName": "Larry Fine"</code>
* <p>
* The {@link JSONPropertyIgnore} annotation can be used to force the bean property
* to not be serialized into JSON. If both {@link JSONPropertyIgnore} and
* {@link JSONPropertyName} are defined on the same method, a depth comparison is
* performed and the one closest to the concrete class being serialized is used.
* If both annotations are at the same level, then the {@link JSONPropertyIgnore}
* annotation takes precedent and the field is not serialized.
* For example, the following declaration would prevent the <code>getName</code>
* method from being serialized:
* <pre>
* &#64;JSONPropertyName("FullName")
* &#64;JSONPropertyIgnore
* public String getName() { return this.name; }
* </pre>

* using strings, and retrieve targeted objects, like a simple form of XPATH.
* Path segments are separated by the '/' char, which signifies the root of
* the document when it appears as the first char of the string. Array
* elements are navigated using ordinals, counting from 0. JSONPointer strings
* may be extended to any arbitrary number of segments. If the navigation
* is successful, the matched item is returned. A matched item may be a
* JSONObject, a JSONArray, or a JSON value. If the JSONPointer string building
* fails, an appropriate exception is thrown. If the navigation fails to find

* JSONStringer provides a quick and convenient way of producing JSON text.

* JSONStringer can produce one JSON text.
* <p>
* A JSONStringer instance provides a <code>value</code> method for appending
* values to the
* text, and a <code>key</code>
* method for adding keys before values in objects. There are <code>array</code>
* and <code>endArray</code> methods that make and bound array values, and
* <code>object</code> and <code>endObject</code> methods which make and bound
* object values. All of these methods return the JSONWriter instance,
* permitting cascade style. For example, <pre>
* myString = new JSONStringer()
* .object()
* .key("JSON")
* .value("Hello, World!")
* .endObject()
* .toString();</pre> which produces the string <pre>
* {"JSON":"Hello, World!"}</pre>
* <p>
* The first method called must be <code>array</code> or <code>object</code>.
* There are no methods for adding commas or colons. JSONStringer adds them for
* you. Objects and arrays can be nested up to 20 levels deep.
* <p>
* This can sometimes be easier than using a JSONObject to build a string.

JSON in Java [package org.json]
===============================
[![Maven Central](https://img.shields.io/maven-central/v/org.json/json.svg)](https://mvnrepository.com/artifact/org.json/json)
JSON is a light-weight, language independent, data interchange format.
See http://www.JSON.org/
The files in this package implement JSON encoders/decoders in Java.
It also includes the capability to convert between JSON and XML, HTTP
headers, Cookies, and CDL.
This is a reference implementation. There is a large number of JSON packages
in Java. Perhaps someday the Java community will standardize on one. Until
then, choose carefully.
The license includes this restriction: "The software shall be used for good,
not evil." If your conscience cannot live with that, then choose a different
package.
The package compiles on Java 1.6-1.8.
**JSONObject.java**: The `JSONObject` can parse text from a `String` or a `JSONTokener`
to produce a map-like object. The object provides methods for manipulating its
contents, and for producing a JSON compliant object serialization.
**JSONArray.java**: The `JSONArray` can parse text from a String or a `JSONTokener`
to produce a vector-like object. The object provides methods for manipulating
its contents, and for producing a JSON compliant array serialization.
**JSONTokener.java**: The `JSONTokener` breaks a text into a sequence of individual
tokens. It can be constructed from a `String`, `Reader`, or `InputStream`.
**JSONException.java**: The `JSONException` is the standard exception type thrown
by this package.
**JSONPointer.java**: Implementation of
[JSON Pointer (RFC 6901)](https://tools.ietf.org/html/rfc6901). Supports
JSON Pointers both in the form of string representation and URI fragment
representation.
**JSONPropertyIgnore.java**: Annotation class that can be used on Java Bean getter methods.
When used on a bean method that would normally be serialized into a `JSONObject`, it
overrides the getter-to-key-name logic and forces the property to be excluded from the
resulting `JSONObject`.
**JSONPropertyName.java**: Annotation class that can be used on Java Bean getter methods.
When used on a bean method that would normally be serialized into a `JSONObject`, it
overrides the getter-to-key-name logic and uses the value of the annotation. The Bean
processor will look through the class hierarchy. This means you can use the annotation on
a base class or interface and the value of the annotation will be used even if the getter
is overridden in a child class.
**JSONString.java**: The `JSONString` interface requires a `toJSONString` method,
allowing an object to provide its own serialization.
**JSONStringer.java**: The `JSONStringer` provides a convenient facility for
building JSON strings.
**JSONWriter.java**: The `JSONWriter` provides a convenient facility for building
JSON text through a writer.
**CDL.java**: `CDL` provides support for converting between JSON and comma
delimited lists.
**Cookie.java**: `Cookie` provides support for converting between JSON and cookies.
**CookieList.java**: `CookieList` provides support for converting between JSON and
cookie lists.
**HTTP.java**: `HTTP` provides support for converting between JSON and HTTP headers.
**HTTPTokener.java**: `HTTPTokener` extends `JSONTokener` for parsing HTTP headers.
**XML.java**: `XML` provides support for converting between JSON and XML.
**JSONML.java**: `JSONML` provides support for converting between JSONML and XML.
**XMLTokener.java**: `XMLTokener` extends `JSONTokener` for parsing XML text.
Unit tests are maintained in a separate project. Contributing developers can test
JSON-java pull requests with the code in this project:
https://github.com/stleary/JSON-Java-unit-test
Numeric types in this package comply with
[ECMA-404: The JSON Data Interchange Format](http://www.ecma-international.org/publications/files/ECMA-ST/ECMA-404.pdf) and
[RFC 7159: The JavaScript Object Notation (JSON) Data Interchange Format](https://tools.ietf.org/html/rfc7159#section-6).
This package fully supports `Integer`, `Long`, and `Double` Java types. Partial support
for `BigInteger` and `BigDecimal` values in `JSONObject` and `JSONArray` objects is provided
in the form of `get()`, `opt()`, and `put()` API methods.
Although 1.6 compatibility is currently supported, it is not a project goal and may be
removed in some future release.
In compliance with RFC7159 page 10 section 9, the parser is more lax with what is valid
JSON than the Generator. For Example, the tab character (U+0009) is allowed when reading
JSON Text strings, but when output by the Generator, tab is properly converted to \t in
the string. Other instances may occur where reading invalid JSON text does not cause an
error to be generated. Malformed JSON Texts such as missing end " (quote) on strings or
invalid number formats (1.2e6.3) will cause errors as such documents can not be read
reliably.

## Instrucciones
1. El servlet fue probado por medio de la herramienta postman.
2. El api key es 12345678. En caso que no coincida el api key, da el error 403. La variables es x-api-key.
3. En el primer caso, si no existe el registro en la base de datos, retorna el error 404.
4. La base de datos utilizada es la base de datos de pedro, que es 192.168.67.159:5432/Geo.
5. El array de objetos que entrega es un array de objetos JSON.
