you probably got an action not found since your logic"redirect href attribute has the incorrect value. your action mapping for /strex/welcome is also not correct since for the welcome action.
1. if your context-root is 'strex', your action mapping path should just be '/welcome'. 2. your redirect href value should be '/strex/welcome.do'
