I am new to Spring and trying to make integration between spring and primefaces. I am getting 404 page no found when I run the project on tomcat after adding the ContextLoaderListener and RequestContextListener.

I tried to find a solution online but I am confused because most of the examples are using jsps.
please point me to the problem, I am attaching the github link.

Your views are NOT in webapp/WEB-INF folder as you defined in your InternalViewResolver bean.
They are located in webapp folder.

How to add parameters in rest api for specific response in code?

I have created my very first basic rest api. Its working find and give me output in xml using this url
http://localhost:8080/Webservice/Test/RestClient
Now, I'm thinking If I want my api to ask server only specific data then I how can I use parameters for the same in api url.
Here is my little updated code
package RestClient;
//import javax.servlet.annotation.WebServlet;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.xml.bind.annotation.XmlRootElement;
#Path("/RestClient")
#XmlRootElement
public class Restwebclient {
#GET
#Produces(MediaType.TEXT_XML)
public String sayXMLHello(#PathParam("x") int x, #PathParam("y") int y) {
String output = "";
if (x == 1 && y == 1) {
output = "<?xml version=\"1.0\"?>" + "<hello> Hello Jersey" + "</hello>";
}
else if (x == 2 && y == 2) {
output = "<?xml version=\"1.0\"?>" + "<hello> Hello Jersey" + "</hello>";
}
return output;
}
}
And web.xml is here
<?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" version="3.1">

<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-name>JAVA WS</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>

<param-value>RestClient</param-value>
</init-param>

</servlet>
<servlet-mapping>
<servlet-name>JAVA WS</servlet-name>
<url-pattern>/Test/*</url-pattern>
</servlet-mapping>
</web-app>
But when run the url passing parameters like this nothing comes up in output
http://localhost:8080/Webservice/Test/RestClient?x=1&y=1
Note: Expected output from above parameters in url should be first if condition
May I know What I'm missing to achieve this ?

You are sending parameters in query so you should use #QueryParam and not #PathParam. change method to:
public String sayXMLHello(#QueryParam("x") int x, #QueryParam("y") int y) {
Query Params:
http://localhost:8080/Webservice/Test/RestClient?x=1&y=1
Path Params need to change Path:
#Path("{x}/{y}/RestClient")
http://localhost:8080/Webservice/Test/1/1/RestClient

Error on a JERSEY REST project (and tomcat)

I met a surious problem when I want to develop an API to call an "exterior" method (this method is called "createClientNode" which is a simple request for neo4j).
Anyways, this is my web.xml :
<?xml version="1.0" encoding="UTF-8"?>

#Path("/API")
public class MyService {

#Produces({ MediaType.APPLICATION_JSON })
public Node createNode(#DefaultValue("default_id") #QueryParam("ID") String id) {
GraphManagement gm = new GraphManagement();
Node node = gm.createClientNode(id);
return node;
}
#GET
#Path("/node/{ID}")
#Produces({ MediaType.APPLICATION_JSON })
public Node getNode(#PathParam("ID") String id) {
GraphManagement gm = new GraphManagement();
Node node = gm.getClientNode(id);
return node;
}
#Path("/test")
#GET
#Produces(MediaType.TEXT_PLAIN)
public void afficher() {
System.out.println("test");
}
}
the error that I get is "the Servlet jersey-serlvet is not available".
I have the impression that I have-perhaps- a problem with a specific JAR or Tomcat, but I coudn't find the cause of this problem. So, can anyone help me please because I tried a loooong time with this!
