The start batch file

Hi

I hope you are well, i have been following along with your camunda tutorial on youtube https://youtu.be/HxtZf5VD6lQ?list=PLJG25HlmvsOUnCziyJBWzcNh7RM5quTmv, I am stuck on deployment section, when i deploy the SimpleDemo.war file to wildfly standalone deployments it does not change the state to deployed it stays on undeployed war file. I refresh my cockpit web it deoes not show my simple demo file. The camunda wildfly i am using is 7.21.0 and and i am using latest camunda modeler and latest eclipse. Can you please kindly assist?
