[Karan]

Hi Team,

I have upgraded flowable to 6.7.2 version. But is not starting up in tomcat. Catalina.out does not show any entries after org.apache.catalina.startup.HostConfig.deployWAR Deploying web application archive

Hi,

have a look here;

Flowable-ui and tomcat 10

Hello, A simple (beginner) question: as described in Flowable applications · Flowable Open Source Documentation, I installed Tomcat 10, put the flowable-ui war (from 6.7.2 distrib) in the Tomcat war folder, start Tomcat and nothing at http://localhost:8080/flowable-ui. In the logs, Tomcat said that the war is correctly installed, no errors. Do I forget something? Thanks, Chris

Regards,

Yvo

Hi Yvo,

Thanks for responding quicky. Yes, I found out that flowable is not compatible with apache 10.x after some googling lead me to the github page flowable-rest WAR application not working with version 10 of Apache Tomcat · Issue #2939 · flowable/flowable-engine · GitHub

Now, I have installed flowable on tomcat 9.0.56 and it’s running fine.

Regards,
Karan
