Error 404: SRVE0190E: File not found: /stores/servlet/home

This could happen due to multiple reasons but a couple of reasons that I have seen prominently and please free to add in your comments.

Debugging 1st approach: WebServer configuration
1.Goto access.log in C:\IBM\HTTPServer\logs  and you will see 127.0.0.1 - -"GET /shop/home HTTP/1.1" 404 60
2. Goto C:\IBM\HTTPServer\conf and make sure the httpd.conf and make sure toolkit is pointing to correct directory.
3. Before you make any modifications, do take a backup of httpd.conf

Debugging 2nd approach:

1. Make sure the WC->properties->Java EE Module dependencies has Stores.war checked.
