I have a project in Eclipse and trying to call a servlet from the web browser. The image shows the structure of my project. Although I set the url
in the annotation I still can't get find the resource.
Here is my code:
package java.enablingKeyWordSearch;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
@WebServlet(asyncSupported = false, name = "HelloServlet", urlPatterns = {"/hello"})
public class TestServlet extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
resp.setContentType("text/html");
PrintWriter out = resp.getWriter();
out.write("<h2>Hello Servlet One </h2>");
out.close();
}
}
I have tried calling the servlet using the following: http://localhost:8080/MultiKeywordSearch/hello http://localhost:8080/MultiKeywordSearch/src/java/enablingKeyWordSearch/hello
... and so on. Yet, I get an HTTP Status 404 Error.
This is the content of my web.xml
file:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
<display-name>MultiKeywordSearch</display-name>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
</web-app>
I am using Apache Tomcat v8.0 if that makes a difference.
UPDATE: showing source listing in the new screenshot; removed java namespace
EDIT 2.0 web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
<display-name>MultiKeywordSearch</display-name>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>HelloServlet</servlet-name>
<servlet-class>enablingKeyWordSearch.TestServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloServlet</servlet-name>
<url-pattern>/multiKeywordSearch</url-pattern>
</servlet-mapping>
</web-app>
The enablingKeyWordSearch.TestServlet.java
file:
package enablingKeyWordSearch;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.annotation.MultipartConfig;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
//@WebServlet(asyncSupported = false, name = "HelloServlet", urlPatterns = {"/hello"})
@WebServlet(name = "HelloServlet", urlPatterns = {"/multiKeywordSearch"})
@MultipartConfig
public class TestServlet extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
resp.setContentType("text/html");
PrintWriter out = resp.getWriter();
out.write("<h2>Hello Servlet One </h2>");
out.close();
}
}
Still getting a 404 error sadly.
@WebServlet("/multiKeywordSearch")
@MultipartConfig
and then try this.
http://localhost:8080/MultiKeyewordSearch/multiKeywordSearch
Try updating your web.xml
<servlet>
<servlet-name>helloServlet</servlet-name>
<servlet-class>java.enablingKeyWordSearch.TestServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>helloServlet</servlet-name>
<url-pattern>/hello</url-pattern>
</servlet-mapping>
