Hi Issouf,
if you are stuck with the message Fail - Application at context path {/warName] could not be started, check your JRE Version.
A customer of ours had the same issue, and updating the SAP Machine to Version 17 solved the issue.

Another hint: don't 100% trust the SAP Enable Now Manager Installation Guide when it advises you to modify the config.properties file prior to deploying the Manager .war file. Just skip this entire "Pre-Parametrization of the Installer" chapter. 99.9% of customers I've dealt with broke the .war file when following this advice. Just use the original Manager .war file and everything will run smoothly, provided other software and hardware requirements are met.
