Introduction to Spring 5 and Spring Boot (2022): Lab Setup Instructions (Windows OS - Java 11, Eclipse 2022-03, Tomcat 9)

Below are the standard requirements for this course. If you have any questions or issues, please contact us.

Important Note: Student lab files are required on each computer used for the course. The links for these are not in this lab setup, and you should receive them separately.

Other notes:

  • It’s a good idea to keep downloaded software install files on the machines during the class in case of problems that require a re-install.
  • Cloning a setup is generally not a problem. If it is, we’ll mention it in the software section (for example, much of the IBM/RAD-WAS software can be problematic in this regard).

Hardware and classroom setup.

Each student and the instructor shall have a workstation that fulfills the listed requirements.

  • Required: Intel-compatible processor (with reasonably recent hardware).
  • Memory: 8GB min recommended
  • Disk Space: Free disk space for software installs (generally minimum 2GB)
  • Operating System: Windows OS (Any modern version - e.g. Windows 10. - labs have not been tested on Windows 8 variants)
  • Required: Zip utility. A good free one is 7-zip
  • Required: Adobe Acrobat Reader
  • Required: One of Firefox browser (https://www.mozilla.org/en-US/firefox/new/) or Chrome browser (https://www.google.com/chrome/). Edge browser is not sufficient.
  • Recommended: Internet access
  • Recommended: Class machines networked together - allows students to access a shared network directory.

Install 7-zip 

We’ve found that there are sometimes problems using the built in Windows archive/zip utility. This generally has to do with long path lengths that it can’t handle. Use 7-zip to extract the labs and any software zips which we’ve found very reliable.

  • Can try direct download link for 64-bit install: https://www.7-zip.org/a/7z2301-x64.exe
  • If that doesn’t work, go to home page https://www.7-zip.org
  • Near the top of the page, find the download link for your bitness (probably 64 bit), and download the installer.
  • Execute the installer, and take all the defaults.
  • You can now extract zip files by right clicking on them, and selecting 7-Zip | Extract ...

Lab Files: Each student and instructor must have lab files installed (links to these files are generally sent separately via e-mail).

  • Extract the lab files to a location conveniently accessible to the student (e.g. C:\ )
  • Recommend using utility like 7-zip, not Windows built-in extractor.
  • If using folder other than C:\, make sure that students know where they are.

Other instructor requirements for the classroom

  • Projector or large screen TV capable of 1280x800 or higher resolution. Instructor must be able to use this to project slides.
  • Whiteboard (preferred) or flip charts with markers.

Install Java Development Kit – JDK 11 (11.0.24)

  • Note that any JDK 11 version should work fine. Other close (later) Java versions (e.g. Java 12 or 13) should be fine also, but have not been tested.
  • Download:
  • From https://www.oracle.com/java/technologies/javase/jdk11-archive-downloads.html download the installer file for the Windows x64 Installer
    • File name is something like: jdk-11.0.24_windows-x64_bin

  • Run the installer and take all defaults.

  • Create or modify environment variables. This will add an environment variable JAVA_HOME, and modify your path to include the jdk bin folder. For windows set the following.
    • JAVA_HOME:
      • Navigate to the System Properties widget > click the Advanced tab > click the Environment Variables button
      • In the bottom half of the dialog, click New to add a new System variable
      • Variable name: JAVA_HOME (this is case-sensitive)
      • Variable value: C:\Program Files\Java\jdk-11.0.24 (or adjust to the actual path for your JDK version and where you installed the JDK – please double-check this path – probably best to copy and paste it)
      • Click OK
    • Path:
      • Find this existing entry in the bottom half of the Environment Variables button, and click Edit
      • Click in the Variable value field and move your cursor all the way to the left (pressing Home on your keyboard should do this quickly for you)
      • Check whether the value below is already present, or add it at the beginning if necessary (make sure you get all of this, including the trailing semicolon, with no spaces):

        %JAVA_HOME%\bin;
         
    • Click OK repeatedly (likely in 3 different dialogs) until all the dialogs close.

  • Open a terminal prompt, type the below, and press Enter

    javac -version

  • You should get a message that tells you the version. If the command is not found, you did something wrong.
  • Close the terminal prompt. You’re done installing Java

Install Eclipse 2022-03 for Enterprise Java Developers (Windows OS - 64 bit Installer)

  • NOTE: We are using the Eclipse Installer for this - different from the zip file install we've often used
  • Download the installer: Note that Eclipse only seems to provide direct links for old versions - i.e. there is no page where the link is preserved (that we've found).
  • Create install folder:
    • Create the folder C:\eclipse-2022-03. This will install all the Eclipse files into C:\eclipse-2022-03\eclipse.
    • Note that the Eclipse installer will NOT allow you to install directly into C:\
  • Install:
    • Run the installer
    • In the first dialog, choose "Eclipse IDE for Enterprise and Java Developers"
    • In the next dialog, set the following
      • Choose your Java VM: It may auto-detect your correct VM - if so, then use it. If not, then browse to the correct install folder for your Java installation
        • Choose the Java VM that you installed earlier in the setup instructions for this course.
      • Installation folder: Select the C:\eclipse-2022-03 folder you created above
      • Leave "create start menu entry" and "create desktop shortcut" checked
    • Click Install - It should install cleanly.
  • Test
    • Run the Eclipse program (there should be a shortcut on the desktop)
    • Accept the default workspace, and let it load
    • Go to menu item Window | Preferences | Java | Installed JREs
      • Make sure your Java install is listed in the dialog, and is checked to be the default Java install that is used.
      • Click Cancel out of all dialogs
    • Quit Eclipse
  • That’s it. You’re done installing Eclipse
