appmap-java VS saml-rails

AppMap currently supports Ruby, Java, Python, and Javascript projects and the libraries are MIT licensed.

Add the appmap Java agent to your Maven or Gradle configuration - or just download the JAR file from https://github.com/applandinc/appmap-java/releases

found bug when having empty app.yml: https://github.com/applandinc/appmap-java/issues/80 but if filled out it works.

Hey that’s cool. Something has to trigger AppMap to start and stop recording. Tests are one way; each test defines the boundary of a recording. Another way is to wrap the code you want to run using this function - https://github.com/applandinc/appmap-java/blob/f11ab539f3d2572e1c6583db5fadccb4483c50eb/src/main/java/com/appland/appmap/record/Recorder.java#L229 - see also https://github.com/applandinc/appmap-java/blob/f11ab539f3d2572e1c6583db5fadccb4483c50eb/src/main/java/com/appland/appmap/record/Recorder.java#L58 - LMK if you get it working - you will need an appmap.yml of course.

For full usage instructions, check out appmap-java on GitHub.

We’ll use the same Rails 6 application for each step - the source code is available here. The main branch adds Devise with a User model to a brand new Rails app using Postgres as the database. The application doesn’t do anything - there is an index route and a logged in route that will tell you the email for the current user. This guide assumes proficiency with Rails, so it will skip some details. We’ll also use some intentionally naive approaches to demonstrate common challenges of SAML SSO.

I recently dug into execution traces of a saml-rails example app, looking for "points of interest" in the code. Here are five interesting things that I learned about SAML and how to integrate SAML into a realistic application.
