- Lab (Demo) 7: TAS Service Bindings
- Lab 8: Metrics and Tanzu Observability == Lab Setup

To build the applications in this workshop, you’ll need a couple of things:

Git
Java JDK 11
Your favorite IDE or editor (e.g., Eclipse or Spring Tool Suite, IntelliJ IDEA, NetBeans, Visual Studio, etc)

We’ll be pushing applications and creating services in Tanzu Application Server (TAS).

Ensure you are able to login to your organizations TAS foundation.
Click the Tools link and…
- download and install the CLI matching your operating system
- login to the CF CLI (cf login -a api.run.pivotal.io)

IDE Setup and tips

💡	This section shares some optional tips for configuring your IDE for an optimal experience during the workshop!

Eclipse / Spring Tool Suite

Exclude java.awt.* from auto-complete suggestions: Preferences → Java → Appearance → Type Filters → Add… → java.awt.*

This way when you need to auto import something with List you don’t get the dialog box that asks if you want java.awt.List when you really want java.util.List
Configure Maven Auto Update: Preferences → Maven → [✔] Automatically update Maven projects configuration

Allows you to change a pom.xml and have the eclipse classpath automatically change without having to trigger the change manually.
Open pom.xml in XML view: Preferences → Maven → User Interface → [✔] Open XML Page in the POM editor by default

This will get you straight to the XML when you first open your pom.xml
Show line numbers: Preferences → General → Editors → Text Editors → Show Line Numbers

Very useful when collaborating and you need to explicitly state which line number you are referring to.
Automatically refresh resources changed outside of Eclipse: Preferences → General → Workspace → Refresh using native hooks or polling

This enables Eclipse to recognize changes to files that have been modified outside of Eclipse. Pretty handy.
Close all views you don’t need: Give yourself more space to view/write code by closing any views in the perspective that you don’t use, such as: Outline, Spring Explorer, and Servers
Boot Dashboard: Use it, it’s awesome :)
