I am new to JSP and struggling with this issue. I created a Hello World page and worked fine. After I made some changes, I uploaded the new version of my index file several times. I have even deleted my index.jsp file from the server, along with the WEB-INF and META-INF folders. I've done this several times, even at shell level, yet when I visit the .JSP file in my browser, it's the same file. It will not update. In NetBeans IDE, I have built and ran my project and it works correctly, displaying the correct file. I've even opened the file in a simple editor first before uploading to make sure the build file was the new updated file and it is. So why after I upload it, does the same page exist? How is that possible?
I've cleared my browser cache, deleted history, everything I know to do. This is not behaving like any other programming language I've used before.
