我正在开发eclipseide并创建一个web服务程序。ide在导入时出错
import javax.jws.WebService; import javax.jws.WebMethod; 错误显示无法解析导入javax.jws

import javax.jws.WebService;
import javax.jws.WebMethod;

@WebService
public class Hello {
    private final String message = "Hello, ";

    public Hello() {
    }

    @WebMethod
    public String sayHello(String name) {
        return message + name + ".";
    }
}
