Jackson All 1.8.5 Jar Download
In this article, we will show you how to download and use Jackson All 1.8.5 Jar in your Java projects, and what are the benefits of using this comprehensive JSON library.
What is Jackson All?
Jackson All is a package that contains all the Jackson modules that are part of the official Jackson distribution. These modules are:
Jackson Core: This is the core low-level incremental (streaming) parser and generator abstractions used by Jackson Data Processor. It also includes the default implementation of handler types (parser, generator) that handle JSON format.
Jackson Annotations: This module contains standard Jackson annotations that can be used to configure and customize data binding behavior.
Jackson Databind: This module provides high-level data binding functionality for Jackson. It allows you to read and write JSON from and to Java objects, using annotations or configuration options.
Jackson Tree Model: This module provides an in-memory tree representation of JSON documents, similar to DOM for XML. It allows you to manipulate JSON data as Java objects, using a fluent API.
Jackson Data Formats: This module provides support for reading and writing other data formats than JSON, such as XML, YAML, CSV, Smile and CBOR.
Jackson Data Types: This module provides support for some common Java data types that are not part of the JDK, such as Guava, Joda-Time and Hibernate.
Jackson Modules: This module contains various extensions and add-ons for Jackson, such as Afterburner, Mr Bean, Parameter Names and JAX-RS providers.
By using Jackson All 1.8.5 Jar Download, you can access all these features with a single dependency in your project.

How to Use Jackson All 1.8.5 Jar in Your Java Code?
Once you have downloaded and added Jackson All 1.8.5 Jar to your project, you can start using it in your Java code. Here are some examples of how to use different Jackson features with Jackson All 1.8.5 Jar:
Streaming API
The streaming API allows you to read and write JSON data in a streaming fashion, without loading the whole JSON document into memory. This is useful for processing large or unknown JSON data efficiently. To use the streaming API, you need to create a JsonParser or a JsonGenerator object from a JsonFactory instance, and then use their methods to parse or generate JSON tokens.
For example, the following code reads a JSON array of numbers from an input stream and prints their sum:
import org.codehaus.jackson.JsonFactory;
import org.codehaus.jackson.JsonParser;
import org.codehaus.jackson.JsonToken;
import java.io.InputStream;
public class StreamingExample
public static void main(String[] args) throws Exception
// Create a JsonFactory instance
JsonFactory factory = new JsonFactory();
// Create an input stream with some JSON data
InputStream input = StreamingExample.class.getResourceAsStream("/numbers.json");
// Create a JsonParser object from the input stream
JsonParser parser = factory.createJsonParser(input);
// Initialize the sum variable
int sum = 0;
// Loop through the JSON tokens
while (parser.nextToken() != null)
// Check if the current token is a number
if (parser.getCurrentToken() == JsonToken.VALUE_NUMBER_INT)
// Get the number value and add it to the sum
int number = parser.getIntValue();
sum += number;
// Close the parser
parser.close();
// Print the sum
System.out.println("The sum is: " + sum);
The following code writes a JSON object with some properties to an output stream:
import org.codehaus.jackson.JsonFactory;
import org.codehaus.jackson.JsonGenerator;
import java.io.OutputStream;
public class StreamingExample
public static void main(String[] args) throws Exception
// Create a JsonFactory instance
JsonFactory factory = new JsonFactory();
// Create an output stream
OutputStream output = System.out;
// Create a JsonGenerator object from the output stream
JsonGenerator generator = factory.createJsonGenerator(output);
// Write the start of the JSON object
generator.writeStartObject();
// Write some properties with values
generator.writeStringField("name", "John");
generator.writeNumberField("age", 25);
generator.writeBooleanField("married", false);
// Write the end of the JSON object
generator.writeEndObject();
// Flush and close the generator
generator.flush();
generator.close();
Data Binding
The data binding feature allows you to read and write JSON data from and to Java objects, using annotations or configuration options. This is useful for mapping JSON data to Java classes and vice versa. To use the data binding feature, you need to create an ObjectMapper instance, and then use its methods to serialize or deserialize JSON data.
For example, the following code defines a Java class that represents a person with some properties:
import org.codehaus.jackson.annotate.JsonProperty;
public class Person
@JsonProperty("name")
private String name;
@JsonProperty("age")
private int age;
@JsonProperty("married")
private boolean married;
public Person()
public Person(String name, int age, boolean married)
this.name = name;
this.age = age;
this.married = married;
// Getters and setters omitted for brevity
The following code reads a JSON object from an input stream and converts it to a Person object:
import org.codehaus.jackson.map.ObjectMapper;
import java.io.InputStream;
public class DataBindingExample {
public static void main(String[] args) throws Exception {
// Create an ObjectMapper instance
ObjectMapper mapper = new ObjectMapper();
// Create an input stream with some JSON data
InputStream input = DataBindingExample.class.getResourceAsStream("/person.json");
// Read the JSON data and convert it to a Person object
Person person = mapper.readValue(input, Person.class);
// Close the input stream
input.close();
// Print the person's properties
System.out.println("Name: " + person.getName());
System.out.println("Age: " + person.getAge());
