由 此生再无相见时 提交于 2021-02-20 04:49:42
问题 I've a Jsp that returns this html 5: <html> <head> <title>Application</title> <!-- Some script includes here --> </head> <body> <!-- My html here --> </body> </html> At the moment the user need to disable caching into the browser, else the old page is reloaded every time. I tried to force no-caching with a scriptlet in that way, but without success: <% response.addHeader("Cache-Control","no-cache"); response.addHeader("Expires","-1"); response.addHeader("Pragma","no-cache"); %> Asde the fact

How to choose a value of a HashMap in select Struts2?

Tested with debugger and has the correct value taken from database. positions is a list with id and name. So

JSF ValueChangeListener not working

由 余生颓废 提交于 2021-02-19 03:32:30
问题 I am learning how to use events with JSF. For some reason, the program is not changing the value in the text field when I change the value of the dropdown menu. The page loads and shows "Germany", but does not change the text field to "DE". Any suggestions?
