I a creating a spring-mvc webapp. Without embedding flowable, it worls fine- servlet starts correctly.

But after adding flowable, when I start the application, the flowable tables and all are created but when initializing server, it says:

Type Exception Report

Message Servlet.init() for servlet [dispatcher] threw exception

Description The server encountered an unexpected condition that prevented it from fulfilling the request.

Hey @Prachi,

It seems like you are not using the Spring Boot starters provided by Flowable. We are explicitly disabling the Spring Boot liquibase support and something like this cannot happen.

You can also manually disable this by setting spring.liquibase.enabled=false.

Cheers,
Filip
