Unable to start a BSP application

I have created a BSP application and activated it. Properties tab of the BSP page has the following URL : http://sapdevqa:1080/sap/bc/bsp/sap/zbookshop/default.htm When I test this application, system is trying to access default.htm page at this address and coming out with an error. But the default.htm page itself is at the following address on the Sap server : http://sapdevqa:1080/sap/bc/bsp_dev/sap/zbookshop/default.htm

Does anybody know why the system is accessing the service ZBOOKSSHOP in BSP directory instead of BSP_DEV ?
