## Introduction



Integrating proxies that need authorization using the Selenium framework and Java programming 

language can be challenging. 



This tutorial contains complete code demonstrating how [Oxylabs’ Residential Proxies](https://oxy.yt/RrBU) can be 

easily integrated with Selenium using Java. 



## Prerequisites



- Download and install [Maven](https://maven.apache.org/download.cgi).

- Download and install [Java SE Development Kit](https://www.oracle.com/java/technologies/downloads/).

- Download and install [Google Chrome](https://www.google.com/chrome).



## Requirements



To make this integration easier, we used [BrowserMob Proxy](https://github.com/lightbody/browsermob-proxy) 

as a middle layer. It runs proxies locally in JVM and allows chaining of Oxylabs' authenticated proxies. 

If you’re using Maven, add this dependency to the `pom.xml` file:



```xml



    net.lightbody.bmp

    browsermob-core

    2.1.5



```



The other library used in this project – [WebDriverManager](https://github.com/bonigarcia/webdrivermanager), 

is optional. It just makes downloading and setting up [Chrome Driver](https://chromedriver.chromium.org/downloads) 

easier. To use this library, include the following dependency in `pom.xml` file:



```xml



    io.github.bonigarcia

    webdrivermanager

    5.0.2



```



If you don’t want to use WebDriverManager, download the Chrome Driver and set the system property as follows:



```java

System.setProperty("webdriver.chrome.driver","/path/to/chromedriver");

```



## Running the Code



### Compiling the Source Code



This is a maven project. To compile this project, run the following command from terminal:



```shell

mvn clean package

```



This will create the file `oxylabs.io-jar-with-dependencies.jar` in the `target` folder.



### Running the Jar



To run the jar, execute the following command from the terminal:



```shell

java -cp target/oxylabs.io-jar-with-dependencies.jar ProxyDemo

```



## Proxy Authentication



Open [ProxySetup.java](src/main/java/ProxySetup.java) file and update your username, password, and endpoint.



```java

static final String ENDPOINT="pr.oxylabs.io:7777";

static final String USERNAME="yourUsername";

static final String PASSWORD="yourPassword";

```



You shouldn’t include the prefix `customer-` in the `USERNAME.` This will be added in the code for country-specific proxies.



## Testing Proxy Connection



Open this project in IDE, open the [ProxySetup.java](src/main/java/ProxySetup.java) file, and run the `main()` function. 

This will print two IP addresses.



- The first IP address will be completely random;

- The second IP address will be a country-specific IP address in Germany.



## Getting Country Specific Proxy



Open [ProxyDemo.java](src/main/java/ProxyDemo.java) file and send a two-letter country code to the function `CountrySpecficIPDemo`.



```java

countrySpecificIPDemo("DE");

```



The value of this parameter is a case-insensitive country code in two-letter [3166-1 alpha-2 format](https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2). For example, `DE` for 

Germany, `GB` for the United Kingdom, etc. For more details, see Oxylabs’ [documentation](https://developers.oxylabs.io/proxies/residential-proxies/select-country#code-example).



## SSL Support



This code uses BrowserMob Proxy, which supports full MITM. 



You may still see invalid certificates warnings. To solve this, install the [ca-certificate-rsa.cer](certificates/ca-certificate-rsa.cer) file in your browser or HTTP client. Alternatively you can generate your own private key rather than using the .cer files distributed with repository.



### Installation Certificate for macOS

- Open Keychain Access

- Selct `System` on left bar

- Click the padlock icon next to `System` and enter your password when prompted

- Select `Certificates` tab on the top

- Drag and drop the `ca-certificate-rsa.cer` file into the `Certificates` tab. You will notice a new certificate appears in the `Certificates` tab with the name `LittleProxy MITM`.

- Right click the certificate and select `Get Info`

- Select `Always Trust`, close the dialog, and enter password again when promoted

### Installation Certificate for Windows



- Open the `ca-certificate-rsa.cer` file in Windows Explorer.

- Right click the file, and select `Install`.

- In the Certificate Import Wizard window, click `Browse` and select `Trusted Publishers`. Click `OK` to continue.

- If you see a Security Warning, select `Yes`.

- Follow the wizard to complete the installation.



## Understanding the Code



All the complexity of setting up BrowserMob Proxy and Chrome Options is hidden in

the [ProxyHelper](src/main/java/ProxyHelper.java) class.



In most cases, you should be able to use this file directly without any change.



To create a Chrome Driver instance, go through a two-step process as follows:



First, create an instance of `BrowserMobProxyServer`. This is where you need to provide the proxy endpoint, username, and password.



The fourth parameter is a two-letter country code. If you don’t need a country-specific proxy, set it to `null`:



```java

BrowserMobProxyServer proxy=ProxyHelper.getProxy(

        ProxySetup.ENDPOINT,

        ProxySetup.USERNAME,

        ProxySetup.PASSWORD,

        countryCode)

```



Next, call the `ProxyHelper.getDriver()` function.



This function takes up two parameters -`BrowserMobProxyServer` and a `boolean` headless. To run the browser in headless mode, send `true`:



```java

WebDriver driver=ProxyHelper.getDriver(proxy,true);

```



`driver` is an instance of Chrome Driver.



Now, you should write your code to use the Chrome Driver.



Before exiting, remember to close the driver and stop the proxy:



```java

driver.quit();

proxy.stop(); 

```
