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 (11.0.23)
- 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-11.0.23_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-11.0.23 (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
