Quick, practical checklist for getting a simple JSP/servlet app working and avoiding the common build/deploy headaches.

JSP is just HTML with special tags — keep static HTML in the JSP and push Java and DB logic into servlets or small helper/DAO classes. Prefer JSTL/EL for iteration and display instead of scriptlets so presentation stays clean and maintainable. For a patient table: servlet retrieves data, sets it as a request attribute, JSP renders it.

Troubleshooting checklist

  • Check the IDE output and the server log files for the full stack trace; that will point to the real error.
  • Validate WEB-INF/web.xml (a small XML typo can block deployment).
  • Verify webapp layout and that compiled classes are under WEB-INF/classes in the correct package folders.
  • Keep third-party jars (JDBC driver) in WEB-INF/lib or the server lib; do not bundle the servlet API itself in the app (that causes classloader conflicts).
  • Clean the exploded app (remove the old folder) before redeploying, and make sure your compile target matches the server Java version.

Minimal webapp layout example:

yourapp/
  index.jsp
  WEB-INF/
    web.xml
    classes/
      com/example/PatientServlet.class
    lib/
      mysql-connector-java.jar

If compiling manually, include the servlet API on the javac classpath and drop class files into WEB-INF/classes. For deployment details and server-side docs consult the Tomcat deployer guide: Tomcat Deployer How-To and the servlet specification: Jakarta Servlet.

Thanks to for pointing toward the docs and to for the clear problem description — the steps above address the errors most people hit when first deploying JSP/servlet apps.

  1. Would be nice if you started to take care how you write, decrypting your last message took me long
  2. What version/type of NetBeans you using if you do not have Apache already with it?
  3. If you choose to use stand alone installation of Tomcat then it has to be the zip version (or tar in *nix case) as Windows installer doesn't provide bat files in Tomcat/bin folder need it by NetBeans in order to use it
  4. If you get errors from your project or IDE please provide full reading of them, not just partial what you remember

If you not sure on using NetBeans you can try JCreator LightEdition which available for free. It does not support integrated Tomcat environment but you can comfortable compile your servlets in it. Just be careful with beans, they have to be compiled separately and execution parameters not modified it will create another folder with compiled classes inside existing bean folder
