需要帮助Java Web App（webapp运行程序，tomcat）heroku（应用程序崩溃）

Question

I have a Java web app on heroku. I created a web app that run webpage + server (apache jena fuseki) using this tutorial from heroku webpage . It works fine on localhost:3030 (execute batch file) and localhost:8080 using

java -jar target/dependency/webapp-runner.jar target/*.war

I push it on heroku with Procfile like this

web: java $JAVA_OPTS -jar target/dependency/webapp-runner.jar --port $PORT target/*.war

The running app shows an Application Error when I tried to access it. Is there any way to resolve this?

My heroku logs

Answer 1

If you look closely, you'll see the main error:

Failed to create directory: /etc/fuseki

I recommend creating any directories under /app on Heroku, as this is the user space.
