After much work, a lot of trial and error I've finally got this almost working. I've been migrating an application created in Eclipse over to IntelliJ and I've gotten to the point where I can build everything fine but I still have to run Tomcat standalone to get it to run. I'd really like to be able to debug here. When I create a local Tomcat configuration and add my application to the deployments, it seems to just ignore my application. When I start the server it starts in 300 ms and there doesn't seem to be any apps. When I open the browser to any URL I get a blank page, not even an error page, completely blank no matter what URL is entered. So I say fine, I'll try to set up remote. I entered the settings for a remote server but basically it says cannot connect to debugging port whenever I try this. Thanks for any help on this.
