Create a dynamic Web Project in eclipse

Create a good project directory as follows:

At first I now created a test.jsp in Web-inf but found Tomcat above run error

Cause of Error:

In Eclipse's Package explorer, check where the files are stored. Since Meta-inf

The contents of the Web-inf folder cannot be released externally, so if you reference a file with these two directories, it is definitely not allowed.

Workaround: Drag test.jsp from Web-inf to WebContent

Run again:

Ii. Creating a Servlet instance

The code for HelloServlet is as follows:

Package com.chenjn.www;

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;

/**
* Servlet Implementation Class HelloServlet
*/
@WebServlet ("/helloservlet")
public class HelloServlet extends HttpServlet {
Private static final long serialversionuid = 1L;

/**
* @see Httpservlet#httpservlet ()
*/
Public HelloServlet () {
Super ();
TODO auto-generated Constructor stub
}

/**
* @see Httpservlet#doget (httpservletrequest request, httpservletresponse response)
*/
protected void doget (HttpServletRequest request, httpservletresponse response) throws Servletexception, IOException {
TODO auto-generated Method Stub
Response.setcharacterencoding ("GBK");
Response.getwriter (). Write ("Hello world! ");
}

/**
* @see Httpservlet#dopost (httpservletrequest request, httpservletresponse response)
*/
protected void DoPost (HttpServletRequest request, httpservletresponse response) throws Servletexception, IOException {
Doget (Request,response);
TODO auto-generated Method Stub
}

}

Restarting the Tomcat server runs the following results:
