Workshop material - Day #1 - Git/VS Code

  • Setting up git

    • Open "https://github.com/HexaInnovLab" in your browser; bookmark this page in your browser
    • Click the signup on the top-right
    • In the following instructions, {hexawareid} is the part preceding @hexaware.com in your email address
    • your username is {hexawareid}-Hexaware, e.g., krishnakumar-Hexaware
    • Use hexaware email address as the email address
    • Select your own password
    • Tell the facilitator the username just created
    • You will get mail to verify your mail address; click the link to complete the verification
    • The facilitator will add you to the hexaware github organization and also give you access to the team's repository
    • You will get a mail inviting you to the HexaInnovLab organization. Please join the organization.
    • Open https://github.com/HexaInnovLab/ftp08, and look at the WEEK1.md
    • Follow the instructions as in https://help.github.com/articles/connecting-to-github-with-ssh/

  • Command Line/Gitbash -- Open Gitbash

    • pwd -- Check and verify that the current working directory is C:\users\Hvuser
    • cd workspace -- change current working to workspace
    • pwd -- Check and verify that the current working directory is C:\users\Hvuser/workspace

  • Git (setup/checkout/clone/pull/push)

    • git --version // should be atleast 2.14+
    • git config --global -l // should throw an error
    • git config --global user.name "<your name>"
    • git config --global user.email <your email>
    • git config --global -l
    • Open https://github.com/HexaInnovLab/ftp08
      • look at source code organization
    • Go back to gitbash and clone the project
    • git clone git@github.com:HexaInnovLab/ftp08.git
    • cd ftp08
    • git status

  • open Visual Studio Code

    • Open folder c:\users\Hvuser\workspace\ftp08
    • Browse the directories to understand the repository structure

Workshop material - Day #2 - MySQL Workbench/Cli/Curl/Browser to interact w/ application

  • Open MySQL Workbench

  • Open the localhost connection

    • Mac OS: export PATH=$PATH:/Applications/MySQLWorkbench.app/Contents/MacOS and then you can use the command line mysql -u root -p hexawareftpdev

  • CREATE DATABASE FTP08; and click the lightning button

  • CREATE USER 'FTP08'@'localhost' IDENTIFIED BY 'FTP08';

  • GRANT ALL ON FTP08.* TO 'FTP08'@'localhost';

  • Open database/database.ddl in VS code

  • Copy the entire contents to MySQL Workbench

  • Execute the ddl

  • Click the table icon against the EMPLOYEE table in the right-hand side schemas section

  • Open database/database.dml in VS code

  • Copy the contents to MySQL Workbench

  • Execute the dml

  • Click the table icon against the EMPLOYEE table in the right-hand side schemas section. You should see the data just inserted.

  • Play around with

    • SELECT with predicates
    • UPDATE statements with predicates
    • DELETE statements with predicates
    • At the end of all the playing around, leave the database with 5 records with ids (1000, 2001

  • Next, we will build and run the java code

  • go to gitbash, ensure you are in workspace/ftp08

  • cd restservice/leavemanager

  • mvn compile

  • mvn exec:java -Dexec.mainClass=com.hexaware.ftp08.util.CliMain

    • As expected, the cli displays only the employee id for the employee; we need to do some code changes before the other attributes such as name will start appearing in the cli. But before that we will test the application as a REST service.
    • Due to a bug in the database connection code, after exiting, there will be an error with a stack trace. Ignore this error.

  • Build the war file as follows:

    • mvn package -- This build a war (java web archive with the code for the REST service)
    • cp target/ftp08-0.0.1-SNAPSHOT.war /D/FTP/apache-tomcat-8.5.16-windows-x64/apache-tomcat-8.5.16/webapps/ftp08.war
    • start tomcat and tail its logs
      • cd D/FTP/apache-tomcat-8.5.16-windows-x64/apache-tomcat-8.5.16
      • rm -rf logs/*
      • ./bin/startup.sh
      • tail -f logs/*
      • curl -vvv http://localhost:8080/ftp08/api/employees | python -m json.tool
      • curl -vvv http://localhost:8080/ftp08/api/employees/2000 | python -m json.tool

  • cd ../../webui/lm-app/

  • npm install

  • ng build

  • cp ../../restservice/leavemanager/target/ftp08-0.0.1-SNAPSHOT.war ./ftp08.war

  • cd dist

  • jar -uvf ../ftp08.war *

  • cd ..

  • jar -tvf ftp08.war

  • cp ftp08.war /D/FTP/apache-tomcat-8.5.16-windows-x64/apache-tomcat-8.5.16/webapps/ftp08.war

  • Notice that the tail terminal shows that the new version of the web application archive is now getting deployed

  • Open Chrome browser and navigate to http://localhost:8080/ftp08/

  • You should be able to see the employee ids as you have entered them in the local mysql database

Workshop material - Day #3 - Setup Jira

  • signup for a jira id using your hexaware email address. Use the hexaware email address, the UI already selects the hexawareid as the username.
  • inform your facilitator that you have signed. s/he will add you to the required jira project.
