To complete the Twilio Java quickstarts, you'll need to have the followingtools installed:

• Java
• A web server capable of running Java Servlets
• The twilio-java helper library

Install Java

If you are on a Mac or Linux machine, you probably already have Java installed.Otherwise, you can follow the excellent installation instructions on the Javawebsite.

Install the twilio-java library

Twilio's Java helper library allows you to interact with the Twilio API whilewriting idiomatic Java code. There are two ways to install the twilio-javalibrary.

Option 1: Use Maven

Maven is a tool that makes it easy to use third party Java libraries in yourprojects. Most computers will already have Maven installed. Mac and Linux userscan check by running:

in the Terminal. If you get back a version number, you're good to go. If you get back

follow these Maven installinstructions to get Maven on your Windows, Mac or Unix machine.

Once you have that, either set up a new pom.xml file for your project, or addthe following <dependency> to your existing pom.xml file:

pom.xml

Then save this file and at the command line, run:

Maven will automatically download the library.

Option 2: Download the .jar directly

If you're not running a Maven project, you can download the jardirectly. Head to this twilio-java download page,and select the most recent version number. Then download thetwilio-java-sdk-X.Y.Z-jar-with-dependencies.jar file.

This .jar file contains everything you need to write code using the twilio-javalibrary. To use it, you'll have to add it to your Java classpath. One way is toadd the following line to your .bashrc startup file.

.bashrc

This way Java will automatically include the jar in its classpath for everycommand you run in the Terminal.

Alternatively, pass in the classpath as a command line option when compiling aJava file. What genre is keygen music.

If you use a tool such as Eclipse or IntelliJ, consult your documentation abouthow to add .jar files to your build path.

Installing a Java web server

To run the quickstart examples, you can use any server which can run JavaServlets. We will walk through installing Apache Tomcat, a popular web serverthat can run Java applications.

Download Tomcat

Head to the Apache Tomcat download page and download the Core Binarydistribution. Then, navigate to the webapps folder inside the downloadedTomcat directory. Create a new folder (servlet) inside the webapps directorycalled twilio, for our new servlet.

We need to add three files to this new twilio directory.First, create a folder called WEB-INF. Inside that folder createtwo folders, one named lib and one named classes. Copy thetwilio-java-sdk-3.3.10-SNAPSHOT-jar-with-dependencies.jar file to the libdirectory.

Then add the following HelloWorld.java file, creating folders as necessary:

webapps/twilio/WEB-INF/classes/com/twilio/HelloWorld.java

Compile that file to get a HelloWorld.class file. You may need to add theservlet-api.jar file in /path/to/apache-tomcat/lib/servlet-api.jar to yourclasspath before compiling.

You also need a web.xml file to tell Tomcat where to route requests:

webapps/twilio/WEB-INF/web.xml

Test Tomcat

Now, start your Tomcat server.

Now open a browser and navigate to http://localhost:8080/twilio/hello. Youshould see 'Hello World' in your browser.

Let's get started

Congrats, you now have everything you need to start using Twilio and Java!Let's start coding.

Need some help?

We all do sometimes; code is hard. Get help now from our support team, or lean on the wisdom of the crowd browsing the Twilio tag on Stack Overflow.

Are you getting “HttpServlet cannot be resolved to a type” while running your java program while starting Tomcat Server? Yes, I’m referring to this project: https://crunchify.com/how-to-run-java-program-automatically-on-tomcat-startup/

But you may see above mentioned exception while running this program.

You need to add the Servlet API to your classpath. In Tomcat 6.0, this is in a JAR called servlet-api.jar in Tomcat’s lib folder. You can either add a reference to that JAR to the project’s classpath, or put a copy of the JAR in your Eclipse project and add it to the classpath from there.

If you want to leave the JAR in Tomcat’s lib folder:

• Right-click the project, click Properties.
• Choose Java Build Path.
• Click Add External JARs…
• Browse to find servlet-api.jar and select it.
• Click OK to update the build path.

Or, if you copy the JAR into your project:

• Right-click the project, click Properties.
• Choose Java Build Path.
• Click Add JARs…
• Find servlet-api.jar in your project and select it.
• Click OK to update the build path.

If you have a Maven Project then add below dependency:
