JAX-WS multiple endpoints Not Found: Invalid Request

Question

I'm trying implement a web service for two endpoints and getting this error "404 Not Found: Invalid Request" when tried accessing the service after deploying onto the apache toncat 8.

Below are my web service implementation classes, sun-jaxws.xml and web.xml

WebImplementation1.java

package com.ws.soap.services;
import javax.jws.WebService;

@WebService(endpointInterface = "com.ws.soap.services.WebServiceImpl1")
public class WebServiceImpl1  {

    public String printMessage() {
        return "Hello from WebServiceImpl1 ";
    }
}

WebServiceImplementation2.java

package com.ws.soap.services;

import javax.jws.WebService;

@WebService(endpointInterface = "com.ws.soap.services.WebServiceImpl2")
public class WebServiceImpl2 {

    public String displayMessage() {
        return "Hello from WebServiceImpl2 ";
    }
}

sun-jaxws.xml

<?xml version="1.0" encoding="UTF-8"?>
<endpoints xmlns="http://java.sun.com/xml/ns/jax-ws/ri/runtime"
    version="2.0">
    <endpoint name="WebServiceImpl1" implementation="com.ws.soap.services.WebServiceImpl1"
        url-pattern="/impl1" />
    <endpoint name="WebServiceImpl2" implementation="com.ws.soap.services.WebServiceImpl2"
        url-pattern="/impl2" />
</endpoints>

web.xml

Answer 1

Using the exact code supplied (plus the JAX-WS RI jars downloaded from https://jax-ws.java.net/), I was able to create a webapp and successfully access the service endpoints /impl1 and /impl2. Be advised the <url-pattern> and <endpoint ... url-pattern="/impl1"> directives state the resource path to the JAX-WS endpoints within the context path of the enclosing web application.

So, if the name of the webapp is MyWebServices (MyWebServices.war with no other files/code than described in the post, deployed to Tomcat 8) and you have <url-pattern>/impl1</url-pattern> in web.xml, and with a default Tomcat instance listening on port 8080, your web service endpoint would be http://localhost:800/MyWebServices/impl1 with the WSDL available via http://localhost:800/MyWebServices/impl1?wsdl

If you want to customize your context path of your webapp (e.g. you don't want /MyWebServices/... you can use the techniques described in this SO question.

For example, my local Tomcat 8 is running on port 8081:
