私は MyClass が javax.servlet.Servlet 警告ではなく、jetty サーバーにデプロイしている間アプリケーションが起動しないことに直面しています。

以前は jdk8 と weblogic で実行していたときは正常に動作していました。jdk8からopenjdk11に、weblogicからjettyに移行しているときに、この問題に直面しています。

私の web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"     xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee                   http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="WebApp_ID" version="2.5">
<display-name>SomeName</display-name>
<listener>
    <listener-class>StaticQueueConnectionServlet</listener-class>
</listener>
<servlet>
    <servlet-name>Soap11HttpPort</servlet-name>
    <servlet-class>MyClass</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>


<servlet>
    <servlet-name>SchedulerServlet</servlet-name>
    <servlet-class>SchedulerServlet</servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>Soap11HttpPort</servlet-name>
    <url-pattern>/Soap11HttpPort</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>SchedulerServlet</servlet-name>
    <url-pattern>/SchedulerServlet</url-pattern>
</servlet-mapping>

私のWebサービスクラス

@javax.jws.WebService(serviceName = "XXXXXX", 
name = "Soap11HttpPort", 
targetNamespace = "xxxxxxx", 
endpointInterface = "MyInterface")
public final class MyClass implements MyInterface {

@javax.annotation.Resource
private WebServiceContext context;

public Resp ping(final Request request) throws Exception {

    return pesponse;
}

public Response printDocument(
        final Request request) throws Exception {

    try {
        final MessageContext ctx = context.getMessageContext();
        final HttpServletRequest request = (HttpServletRequest) ctx.get(MessageContext.SERVLET_REQUEST);

        return response;

    } catch (Exception exc) {

    }

}

}
