I am trying to run the stock WARs as SpringBoot applications connecting to Postgres according to the documentation: [https://www.flowable.org/docs/userguide/index.html#flowableUIApps](https://www.flowable.org/docs/userguide/index.html#flowableUIApps)

I am using command line:  
java -Dloader.path=$FLOWABLE\_HOME/libs -jar $FLOWABLE\_HOME/wars/flowable-idm.war /  
-Dspring.config.location=$FLOWABLE\_HOME/application.properties

$FLOWABLE\_HOME=~/DevelopmentTools/flowable-6.4.0/wars  
postgresql-42.2.5.jar is in the libs folder

SpringBoot fails with:  
Cannot load driver class: org.postgresql.Driver

Tried multiple combinations without luck. Will keep trying but anyone who has this running as advertised please help.

Hey @temecom,

Unfortunately when using the an executable war you can’t use `loader.path` from Spring Boot. In order to make it work you have 2 options:

- Use a tomcat (or another application server) and put the postgres jdbc driver of those libs
- Patch the `flowable-idm.war` to include the postgres driver
