    So, what happens if you go to the following URL in a browser when Tomcat is running?

    http://localhost:8080/MyServletA/hello
    4 months ago

    C:\Program Files\Java\apache-tomcat-9.0.14\webapps\MyServletA  


    I thought you had named your war file HelloWorld.war, so it seems it isn't.... You called it MyServletA.war? This is important because it will determine your contex-root (e.g. starting URL of your web-application)

    The URL servlet-mapping in the web.xml will tell the mapping
    points to your MyServletA servlet.

    In other words, if your war file is called MyServletA.war, then you need the following action: (notice the capital A, I didn't see that in your code)

    <form method="GET" action="/MyServletA/hello">type some text: <input <br /> type="text" name="any" />

    Did you change the link in your HTML file to something simular to the tutorial?


    <form method="GET" action="/HelloWorld/hello">
    type some text: <input type="text" name="any" />


    <input type="submit">
    </form>

    The link in the HTML file is incorrect, you can't point to a file.

    If you check the tutorial again it should be something like:

    http://localhost:8080/HelloWorld/hello



    if your war file is called HelloWorld.war this URL should work from any browser.

    How do I post the contents of the .war file  


    Sorry, I meant the structure of your war file (like in the small tutorial)

    What is the exact URL you are using again?
    4 months ago
    Please post your html file, your web.xml file, and the contents of your war file.

    Try this:

  • open a cmd window from the tomcat directory (the dir where startup.bat is)
  • set PATH=%PATH%;%JAVA_HOME%\bin;%CATALINA_HOME%\bin
  • run startup.bat
