Hi,

I have a standard tomcat web.xml (3.0 or 3.1, no matter).

I have created an external simple servlet with @WebServlet annotation,
and packaged it to a jar file:

Name of the JAR file?

Package the Servlet has been placed in?

Standard Tomcat downloaded from the ASF or one provided by your package
manager?

Have you tried enabling debug logging for
org.apache.tomcat.util.scan.StandardJarScanner ?

Mark




@WebServlet(name = "TestServlet", urlPatterns = {"/TestServlet"},
loadOnStartup = 1)
public class TestServlet extends HttpServlet {

 private static final Logger log =
Logger.getLogger(TestServlet.class.getName());

 private static final long serialVersionUID = 1L;

 @Override
 public void init() throws ServletException {
 log.setLevel(Level.ALL);
 log.log(Level.WARNING, "TESTSERVLET INIT");
 super.init();
 }

 @Override
 public void destroy() {
 }

 @Override
 protected void doGet(HttpServletRequest req, HttpServletResponse
resp) throws ServletException, IOException {
 processRequest(req, resp);
 }

 protected void processRequest(HttpServletRequest request,
HttpServletResponse response)
 throws ServletException, IOException {
 response.setContentType("text/html;charset=UTF-8");
 PrintWriter out = response.getWriter();

 try {
     out.println("");
 out.println("");
 out.println("");
 out.println("Servlet TestServlet");
 out.println("");
 out.println("");
 out.println("Servlet TestServlet at " +
request.getContextPath() + "");

 out.println("");
 out.println("");
 } finally {
 out.close();
 }
 }

}


So, if I copy the .jar file inside WEB-INF/lib folder of destination 
war

project the log message will appears and the servlet is reachable.

But, if I copy the .jar file inside tomcat/lib folder the annotation
won't be processed.


FYI, in tomcat 7 both cases (inside WEB-INF/lib and tomcat/lib) 
works well.



I searched on breaking changes between tomcat 7 and 8/8.5/9 but nope.
Seems related to jarscanner.but no luck!


Because my servlet is in common to all projects I want to put it inside
tomcat/lib folder and share it to all my projects


Somebody can help me?


Many thanks,

Hi Mark,

Ok, all clear, thanks.
Since the servlet is used by several projects, I force it to be loaded 
via web.xml


Thanks again,

Please see section 8.1 of the Servlet specification.


In a web application, classes using annotations will have their
annotations processed only if they are located in the WEB-INF/classes
directory, or if they are packaged in a jar file located in WEB-INF/lib
within the application.


The same requirement was present in Servlet 3.0 / Tomcat 7 but not enforced.
