这里出了什么问题？

The ResourceConfig instance does not contain any root resource classes.

SEVERE: Exception occurred when intialization

过滤:

我想使用嵌入式码头和JAX-RS(无论是resteasy还是jersey)制作RESTful服务.我正在尝试使用maven/eclipse设置创建.如果我尝试关注http://wikis.sun.com/pages/viewpage.action?pageId=21725365链接我无法解决来自ServletHolder sh = new ServletHolder(ServletContainer.class);

public class Main {

    @Path("/")
    public static class TestResource {

        @GET
        public String get() {
            return "GET";
        }
    }

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) throws Exception {
        ServletHolder sh = new ServletHolder(ServletContainer.class);

        /*
         * For 0.8 and later the "com.sun.ws.rest" namespace has been renamed to
         * "com.sun.jersey". For 0.7 or early use the commented out code instead
         */
        // sh.setInitParameter("com.sun.ws.rest.config.property.resourceConfigClass",
        // "com.sun.ws.rest.api.core.PackagesResourceConfig");
        // …

编辑:我没有意识到所有请求首先进入"Apache",然后被重定向到Tomcat.我在apache2.conf文件中添加了一个新的重定向.请参阅接受的答案了解详情.

我遇到与这个问题完全相同的问题. Jersey REST ResourceConfig实例不包含任何根资源类 但是用户从未回答过问题.

我正在使用Tomcat,没有maven.我按照本教程. http://www.ibm.com/developerworks/web/library/wa-aj-tomcat/index.html

我根据文章对web.xml进行了更改,
即使用正确的包名创建了新的servlet和servlet映射.

<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.packages</param-name>
    <param-value>sample.hello.resources</param-value>
  </init-param>
  <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
  <servlet-name>Jersey REST Service</servlet-name>
  <url-pattern>/rest/*</url-pattern>
</servlet-mapping> 

我已将以下jar部署到tomcat

asm.jar
jersey-server.jar
jersey-core.jar
jsr311.jar

tomcat启动日志具有以下例外.

    com.sun.jersey.api.core.PackagesResourceConfig init

      sample.hello.resources

   com.sun.jersey.api.core.ScanningResourceConfig logClasses
