Hi guys, I'm trying to develop my first web application. I am having trouble with my servlet; in particular, my request.getAttribute method
for my property file is returning null. Here is my code:

uploadData.java


In my uploadData.jsp


Thank you in advance

The Java code in the JSP is just for debug purposes, right?

How do you know it's null?

In case you want to print the value of the property, you should change the JSP like this:
(notice there is no ";" in the second line)

Some background...

I have a page called uploadData.jsp. I want to provide the French and English versions of this page for the user, thus I have variables in my .jsp that
I will be replaced from the ahpd_fr.properties file. Here is the entire .jsp file. It is not complete but it is enough to debug this one task.

Why aren't you using the JSTL to handle internationalization?

My manager suggested this approach. I am a mechanical engineering student on a software development co-op so I am hesitant
to clear my own path. Either way, if I use the JSTL for internationalization, I would still need to make the translations myself and
pull them from a properties file, would I not?

The JSTL handles all that for you.
