11. Click close. We are ready to Rock and Roll. Do a Dance.
12. If you are on Windows : Open the Command Prompt window by clicking the Start button , clicking All Programs, clicking Accessories,
and then clicking Command Prompt. (or use Ctrl + Esc, and type in cmd and launch up command)
13. If you are on Mac or other OS, launch up Terminal.

11
14. Type in the command “java –version” as shown in the screen. If it does not work, go to the trouble shooting section.
15. Troubleshooting:
a. Check if there are any pre-existing Java installs. Uninstall them and reinstall again.
b. Temporarily turn off firewalls and antivirus software.
c. If you get file corrupt message, download the installation file again.
d. Check if you are on 32-bit OS or 64-bit OS and ensure you are making use of the right java download.
Installing Maven
1. Check if Java is installed properly. Type in the command “java –version” as shown in the screen. If it does not work, go to the trouble
shooting section of Java or Reinstall Java.
2. Note that Maven 3.3 requires JDK 1.7 or above, Maven 3.2 requires JDK 1.6 or above, while Maven 3.0/3.1 requires JDK 1.5 or above.

12
3. Download Apache Maven. Visit Maven official website, download the Maven zip file. Example : apache-maven-3.3.3-bin.zip
4. On Windows
a. Unzip the distribution archive, i.e. apache-maven-3.3.3-bin.zip to the directory you wish to install Maven 3.3.3. These instructions
assume you chose C:maven. The subdirectory apache-maven-3.3.3 will be created from the archive.
b. Add the unpacked distribution's bin directory to your user PATH environment variable by opening up the system properties
(WinKey + Pause), selecting the "Advanced" tab, and the "Environment Variables" button, then adding or selecting the PATH
variable in the user variables with the value C:mavenapache-maven-3.3.3bin.
c. You can check if you are using the right value by opening up the folder using “cd C:mavenapache-maven-3.3.3bin” and then
typing the command “mvn --version”.
d. Make sure that JAVA_HOME exists in your user variables or in the system variables and it is set to the location of your JDK, e.g.
C:Program FilesJavajdk1.7.0_51.

13
e. Open a new command prompt (Winkey + R then type cmd) (or terminal on mac) and run “mvn –version” to verify that it is correctly
installed.
5. Unix-based Operating Systems (Linux, Solaris and Mac OS X)
a. Extract the distribution archive, i.e. apache-maven-3.3.3-bin.tar.gz to the directory you wish to install Maven 3.3.3. These
instructions assume you chose /usr/local/apache-maven. The subdirectory apache-maven-3.3.3 will be created from the archive.
b. In a command terminal, add unpacked distribution's bin to your PATH environment variable, e.g. export
PATH=$PATH:/usr/local/apache-maven/apache-maven-3.3.3/bin.
c. Make sure that JAVA_HOME is set to the location of your JDK, e.g. export JAVA_HOME=/usr/java/jdk1.7.0_51 .
d. Run mvn --version to verify that it is correctly installed.

14
Installing Eclipse
1. Check if Java is installed properly. Type in the command “java –version” as shown in the screen. If it does not work, go to the trouble
shooting section of Java or Reinstall Java.
2. Search google for “download eclipse” and choose the first result.

15
3. Choose the right Operation System.
4. We recommend to choose “Eclipse IDE for Java EE Developers”. Choose 32 bit or 64 bit based on your operating system. (Right-click My
Computer, and then click Properties. If "x64 Edition" is listed under System, your processor is capable of running a 64-bit version of
Windows.)
5. Wait for the download to complete. Extract the zip file to a folder (Example : c:eclipse).
6. Note that there is a known problem with the built-in decompression utility on all current versions of Windows. We recommend that you
use a more robust decompression utility such as the open source 7zip when decompressing an Eclipse download. Some people report success
when initially decompressing Eclipse into a root directory (e.g. c:) and then moving it to a more appropriate home (e.g. c:Program
FilesEclipse)
7. Refer to Troubleshooting section of https://wiki.eclipse.org/Eclipse/Installation for more details about troubleshooting Installations

16
Importing Java Eclipse Project
1. Download the zip file & Un zip (extract the contents) the zip file.
2. Check if the folder contains a .project file. Highlighted in the image below. You can also open the folder in windows explorer and check
if it contains .project & .settings & .classpath files . (On mac these files are hidden. We used the command ls –la)
3. Copy the folder path into clipboard. (ctrl + c)

17
4. Launch up Eclipse and give folder name (Other folder name) as the workspace folder. Click OK.
5. Once Eclipse Launches up Go To File -> Import -> General -> Existing Projects into Workspace. Click Next.

18
6. Select Root Directory as the folder we copied earlier (the folder which contained .project, .classpath and .settings files).
7. You should see a project highlighted in the Projects section.
8. If you do not see any project, you are checking a wrong folder. Make sure you browse and select the correct folder containing the .project
and the .classpath files.
9. Click Finish.
10. Your project would be imported and You are ready to work on it.
11. Good Luck and Have a Safe Party

Important Maven Commands
Set Up
1. First you need a maven project. You can download maven projects that are associated with the video. Extract the zip file from our website
www.in28minutes.com and put it into a directory. Identify the top most directory containing the pom.xml. That’s your root pom.xml

24
2. Below is the structure of Zip for our Maven Tutorial. We want to run the third example. The root pom.xml for third project is present in the
folder “3.multi-module-maven-project”
3. Open up Command prompt or Terminal. CD to this folder. For example “cd c:maven-example3.multi-module-maven-project”
4. List the files in the folder. Dir command on windows (and ls on unix based OS). You should see the pom.xml.
5. You are all set to run the maven commands on this project.
mvn clean install
1. This command is used to build any project which is created using Maven. It will build all projects (and subprojects or modules) which are
present in the pom.xml.

25
2. Follow the instructions in the Set Up section. You should be in cmd prompt or terminal and your present working directory should be the
one containing pom.xml of the project you want to work on.
3. Run the command “mvn clean install”
4. All projects should build and you should see Build Success message.
5. If you don’t make sure you are in the correct directory. Go to the “Set Up” section and retry the steps again.

26
mvn tomcat7:run
1. First run “mvn clean install” on the root project. Follow steps given above.
2. Switch to directory containing the web application (war pom.xml). In the below example the war directory is in28minutes-web-servlet-jsp.
3. Run the command “mvn tomcat7:run”. Everything should succeed and you should see a message that the server is started. Note down the
port number.
4. Run the application in browser http://localhost:8080/. It should work and you are all setup to run a web application in tomcat. Good Luck
with learning developing applications now..
