Remarks
In this case, if the jsp:useBean action must create a new session bean, it presumably means the old session timed out.
- The body of the action transfers control to an error page.
If the property name in a jsp:setProperty tag is “*”, the action looks for all parameters of the request whose names that correspond to names of Bean properties, and copies parameter values to Bean properties.
- In this case it will automatically set login, lastname, firstnames, email, and dept, which are assumed to have set methods in the Bean class.
The property saved is a write-only trigger property, which causes the current field values to be written to the row with the currently established key.
Finally the page transfers control back to select.jsp.
