I can successfully invoke servlets, JSP, and HTML in Tomcat via Eclipse. However, if I modify the servlets or JSP, the new versions are not invoked within the eclipse browser, even if I stop Tomcat, manually republish the web application, and then restart Tomcat. I need to directly enter the servlet or JSP in the browser command line for the new version to be invoked. As far as HTML is concerned, at least for one test, a modified HTML never became invoked. I had to copy the HTML to a new file and then invoke that new file in order for it to run with the modifications.
