Debugging a Java Web App using Tomcat & VS Code

Are you looking to debug your Java web app on Tomcat. You've come to the right place. I cover debugging, break points, modifications and reloads. See debugging a Java web app in action.

Fantastic... How to debug the Java web application running on a remote Tomcat server not running locally?

[skillionair]

But how do we get the tomcat server part. Is it an extension? because I cant see it. This is not elaborate at all

Is there a playlist where one can learn to program with JAVA and Visual Studio Code?

Thank you very much, Brandon, for this video. It helped a lot. However, I'm having a hard time watching variables in the debug mode. As a value for the variables I get "Cannot evaluate because of Project [*] cannot be found..". Other debug features work fine: break points hit and step-ins work. What am I missing here? Thanks!

[NotAshamedOfficial]

Exactly what I needed! Thanks so much for making this video!

[jacobovasquez]

Thanks for your video, I'm noob with vscode and I would like to know what extensions you recommend to install on, you know, for getting a good start coding and debugging like you do?

[rudypacheco]

an alert tells me Cannot find any changed classes for hot replace! anyone know what it could be?

[zurikzava]

The "plus" icon doesn't do anything for me, anyone have that issue?

Hey @Brandon, Thanks so much for publishing this helpful in-depth video tutorial. This turned out to be EXACTLY something I was looking for! 🙏 Specially this is really useful for those who face problems running a Java project in other IDEs such as STS. I am also trying to find out now to debug the front end alongside the back end while the application is running in the same browser window which launched upon starting the web app. I have done this for several other Node JS apps which output a front end application (mostly ReactJS); But in this case I think the scenario changes since the Java webapp is running on one port and front end code is just output as response. So far only what I could do is to depend on Chrome DevTools by adding debug points on the loaded JS files from the Sources tab. Please suggest if you have any idea.

Thanks for your video! But how can I update html page?following your steps, I can update java file, but I can’t update html page.if I want to update html page, I have to run war:exploded again and restart tomcat server or publish server(full).how can I update html file with one step in vscode like idea do.(my English is not good, wish you can understand what I’m saying)

I think you don't mention the extension that you're using throughout. Looking on your project page, I can see you're using an expired extension.
