Running Wildfly 20 on Windows cmd

I am trying to run the Wildfly 20 server from the command prompt using the command standalone.bat. Earlier I used the server on Eclipse and it worked fine. I had installed JBoss from Eclipse marketplace. When I am trying to run in from cmd on Windows, I am getting the following error.

WFLYCTL0186: Services which failed to start: service jboss.deployment.unit."ecommerce.war".POST_MODULE: WFLYSRV0153: Failed to process phase POST_MODULE of deployment "ecommerce.war"

Please help me with this. Also, is it possible to start and stop the Wildfly server using a Python Script.
