Oracle Weblogic: Das root-element web-app fehlt in der Anwendungsdeskriptordatei

Ich bin versucht, JAX-RS zur Erstellung eines web service gehostet wird auf einem Oracle Weblogic server. Ich bin neu in diese Technologie, so folgte ich nur tutorials da von meinem Lehrer. Hier ist mein code:

WebContent/WEB-INF/web.xml

<servlet> 
    <servlet-name>Jersey REST Service</servlet-name> 
    <servlet-class> 
    com.sun.jersey.spi.container.servlet.ServletContainer 
    </servlet-class> 
    <init-param> 
        <param-name>com.sun.jersey.config.property.edu.cs157b.restful </param-name> 
        <param-value>AssignmentTwo</param-value> 
    </init-param> 
    <load-on-startup>1</load-on-startup> 
    <servlet-mapping> 
        <servlet-name>Jersey REST Service</servlet-name> 
        <url-pattern>/api/*</url-pattern> 
    </servlet-mapping>
</servlet>

WebContent/WEB-INF/weblogic.xml

<?xml version="1.0" encoding="UTF-8"?>
<wls:weblogic-web-app xmlns:wls="http://xmlns.oracle.com/weblogic/weblogic-web-app" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd http://xmlns.oracle.com/weblogic/weblogic-web-app http://xmlns.oracle.com/weblogic/weblogic-web-app/1.5/weblogic-web-app.xsd">
    <wls:weblogic-version>12.1.2</wls:weblogic-version>
    <wls:context-root>AssignmentTwo</wls:context-root>
</wls:weblogic-web-app>

Hier ist der Fehler, ich bin immer

Root-element web-app fehlt in der Deskriptor-Datei

Ihre web.xml fehlt das root-element <web-app>. Die Verschachtelung ist auch falsch. Die <servlet-mapping> element ist ein element der obersten Ebene wie die <servlet> element nicht geschachtelt ist drin.

Ihre web.xml sollte eine Struktur haben, ähnlich wie diese:

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
      version="3.0"> 

    <servlet>
       <servlet-name>Jersey REST Service</servlet-name> 
       <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class> 
       <init-param> 
           <param-name>com.sun.jersey.config.property.edu.cs157b.restful </param-name> 
           <param-value>AssignmentTwo</param-value> 
       </init-param> 
       <load-on-startup>1</load-on-startup> 
    </servlet>

    <servlet-mapping> 
        <servlet-name>Jersey REST Service</servlet-name> 
        <url-pattern>/api/*</url-pattern> 
    </servlet-mapping>

</web-app>

Wenn Sie eine IDE (wie Netbeans, Eclipse), wenn Sie erstellen eine Web-app erzeugt es einen gültigen web.xml für Sie. Wenn Sie beim erstellen eines REST-web-service wird es wahrscheinlich sogar so konfigurieren, dass eine JAX-RS web.xml für Sie.
