Hi all.
I am in trouble with the refresh button now . It is like this:
I have two
jsp page ,one called a.jsp ,it has a form ,and post to b.jsp.
b.jsp handles the request, and insert a record to the database,then forward back to a.jsp.At this time ,the page seems to be a.jsp ,but the address of the browser is still b.jsp .If refresh , there is one more record inserted to the database.
I think if use a
servlet or
struts' action to do the work which b.jsp does,the problem will appear the same.
If use redirect , I can't pass parameters. I have to display a "inserted done!" at the a.jsp if the record is inserted into the database ,or display "error" on the page and write-back the form data just inputed.
I wonder how to resolve this problem .
Thanks in advance.
