GridWeb Java demos

Hi,
I downloaded the demo web grid for java at https://github.com/aspose-cells/Aspose.Cells.Grid-for-Java/tree/master/Examples.GridWeb.
I deployed the war file on Tomcat v9 successfully but I cannot access any url (The requested resource [/gridwebdemo/] is not available)
Please help me solve the problem or show me where I can see a demo of java spring mvc web grid!
Thank you!
Have a nice day!
