jsp - mapping java servlet and action form -


I follow the tutorial in this. Instead of using Web.xml, I am using the annotation @ webserverlate ("/ coffee sauce"). However, I have trouble understanding servlet mapping between Form Action and Java Servlet. It's weird but sometimes, I can run the code successfully, but occasionally, I get 404 emails. If anybody can discuss some articles about sublet mapping, then I am very much appreciated (I did not find any good resources about this).

If you are using a plain servlet, you will see one of the actions in the form & Lt; Url-pattern & gt; Defined for servlet ( / CoffeeSelect in your code). You can see that 404 errors are usually due to using relative URIs from nested pages in folder structure. Check out this link.
It makes you a bit more complex when you use web framework like JSF, Straits etc., but this is a different story.

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ...
