Question:

I hope you are well. I have the following situation: I am working on a project in which I initially used 3 servlets and everything worked very well, the problem was when I tried to create a fourth servet. For some reason that I have not been able to understand, no JSP wanted to connect with that last servlet (the classic HTTP Status 404 – Not found: The required resource […] is not available appears), it connects with any of the others three, and with their respective GET and POST, but simply not with this fourth. It should be noted that I have verified and indeed I have no writing errors. I don’t know if there is any limitation on the options for the number of servlets that are allowed to be used, such that my project is limited to a maximum of three servlets, or if it is another type of problem. As a development environment I am using NetBeans

I don’t know how to describe the problem very well technically, but I’m making an application using Servlets and JSP and I’m having a specific user authentication problem.

Hey so i am running a program that when a cell on a board(on a jsp) is clicked, a servlet is launched, and that servlet can redirect to 1 of 2 jsp, my problem is that this redirection seems to not be working

I have an application that is integrated with Weblogic and utilizes JSP pages. I am trying to upgrade the servlet from 2.4 to 3.5. I am using eclipse and JAR files. When I go to project Facets to upgrade the servlet to 3.5, the most recent it will let me to is 2.5. Which just gives me an error stating: “Cannot change version of project facet Dynamic Web Module to 2.5.” See photo below. Does anyone have any tips to upgrade the servlet?

i made three files ->javaservlet, xml and html
xml file gives mapping,
html takes one number as parameter and forwards it into javaservlet
java servlet finds its square and prints it but in the browser when i enter a number and submit it the following error is shown
