JSP EL not working post strutsbmigration from 2.5.x to 6.7.0

Hi, I'm trying to migrate application from Struts 2.5.33 to struts 6.7.0 but JSP EL is not working post migration. ${obj.prop} giving empty value. Can someone suggest on this? Servelt api 3.1 will work only on WAS 9? If yes, my WAS version is 8.5.x, will this be a problem for EL not working?
