Application not running

[cherlloydfan]

I’m following the camunda platform 7 tutorial on youtube about how to build an application with spring boot and I’m on the second video now about adding forms and starting up a spring boot project and I’ve done everything as it should be but when I try to run the application it doesn’t work it gives me this error :
org.h2.jdbc.JdbcSQLNonTransientConnectionException: Database may be already in use: null. Possible solutions: close all other connection(s); use the server mode [90020-200]

Has anyone else had this problem? and what does it mean? What can I do about it?

I’m using spring tool suite instead of intelli j so I don;t know whether that has anything to do with it??

Hi @cherlloydfan,

I’m using Spring Tool Suite successfully.

Database may be already in use: null. Possible solutions: close all other connection(s); use the server mode [90020-200]

Most likely you didn’t stop the Spring Boot application before you start the new one.

I’m more productive when I use the Boot Dashboard to start or restart applications:

It’s easier than starting the main class as Java application.

Hope this helps, Ingo
