So I keep getting a 405 error about my GET method. I've double checked and I'm not doing the usual GET/POST mix-up. I've been working on this for two days and I just can't figure it out.
Also, my servlet can't be found unless I put a @Path on it...is that normal? Most of the examples I've seen don't do that but mine won't work any other way.

servlet:

package servlets;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.ws.rs.Path;

/**
 * Servlet implementation class uploadServlet
 */
@Path("/uploadServ")
public class uploadServlet extends HttpServlet {
	private static final long serialVersionUID = 1L;
       
	/**
	 * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		// TODO Auto-generated method stub
		response.setContentType("text/html");
		response.setCharacterEncoding("UTF-8");
		response.getWriter().write("HI!");
		System.out.println("DONE!");
		return;
	}

/**
	 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		// TODO Auto-generated method stub
		
	}

}

index.jsp:

Any help would be gladly appreciated! Thank you!

What happens if you put override annotation

Unfortunately, I still get the error. I also get the error when I change all my get requests to posts and move the code.

This is embarrassing, I just fixed it. Obviously this happens.

In case this thread ever gets stumbled upon here was the solution:

1. In the servlet, replaced @Path with @WebServlet annotation
2. Changed the ajax call url to remove one of the uploadServ's
3. Watch magic occur.

I tried this two fixes, but apparently not at the same time. Whoops..

Hi,

I did not understand this mapping,

<servlet-name>uploadServlet</servlet-name>
<servlet-class>
com.sun.jersey.spi.container.servlet.ServletContainer
</servlet-class>

<servlet-mapping>
<servlet-name>uploadServlet</servlet-name>
<url-pattern>/uploadServ/*</url-pattern>
</servlet-mapping>

Your servlet name is uploadServlet and its in the package servlets.

Also if you use @WebServlet annotation, then its not necessary to map the servlet in the web.xml file.

web.xml contains a metadata-complete attribute in the web-app element.
If set to true all of these will be ignored and web.xml is the only metadata considered.

eg.
<web-app metadata-complete="true" ........version="3.0">
