So far I run Tomcat server (v. 7.0.26) in windows command by catalina.bat start script. If I want to deploy my web app I have to build it by Maven and copy WARs to specify Tomcat deploy directory. When server start everything is ok.
Now I try to connect my web app to IntelliJ IDEA Ultimate 2017.1.4. My app have multiple WARs. At Run/Debug Configuration I add new Tomcat Server. At the Deployment tab I have:
I have to choose Application context but if I set blank for more than one artifact I get error Duplicate context path''. Same situation is when I choose /. If I try to run server nothing deploy. Which application context I should set?
The application context will be part of the URL you have to enter in your browser when accessing the application. You could use the name of your war file:
kb-hook
Then you can enter the adress in your browser and find the application. (Given your Tomcat runs on port 8080) You will maybe have to add a path to a resource within the war behind that URL.
http://localhost:8080/kb-hook/
You could also choose another name, but the name of the war file is chosen quite often.
