Even though both methods may be using the same user-credentials, they are not run in the same environment. The task scheduler does not create a full user environment before launching the script. So there could still be some differences?
Q: why not implement it as a proper Windows service, using the native Commons Daemon wrapper which Apache readily provides? Then you can use Windows "net service stop/start" commands to do the same thing? If it still won't stop, you will need to check your code to see what thread(s) is not shutting down. > > > We have not found any error in all the relevant log files. > > > > We have made the below changes while migration. 1. java upgrade > > from 1.7.0_40 to 1.8.0_25 2.Removed the tomcat-native.dll file from > > the bin folder. > > Why did you remove tomcat-native.dll?
