从我读过的所有内容来看，applet 可以调用它自己的服务器提供的任何服务。这就是为什么我编写并启动了一项服务（在 netbeans 中），我可以在我的浏览器中看到它

http://localhost:12345/server?wsdl

为了连接到服务，我使用了 wsimport 并将文件放在我的小程序目录中，然后我清理并构建了项目。

如果我同时启动（服务+小程序）它工作正常，当我删除策略文件时，它不会。

Caused by: java.security.AccessControlException: access denied                       
("java.util.PropertyPermission" "xml.catalog.ignoreMissing" "read")

我在 Netbeans 中启动了服务并将小程序放在我的本地服务器（xampp）上，我可以通过它访问它

http://localhost/sql/mainapplet.html

但什么也没发生。我做错了什么？

这是代码：

服务器项目：

CP.java

import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;

@WebService(targetNamespace = "GUI")
@SOAPBinding(style = Style.RPC)
public class CP {
public String getResults(String u, String p, String s, String se, String q) {
  ...
 }
}

服务器.java

public class Server {
public static void main(String[] args) {
    CP server = new CP();
    Endpoint e = Endpoint.publish("http://localhost:12345/server", server);
 }
}

客户项目：CP.java

package gui;

import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.xml.ws.Action;


/**

 * JAX-WS RI 2.2.4-b01

 */
@WebService(name = "CP", targetNamespace = "GUI")
@SOAPBinding(style = SOAPBinding.Style.RPC)
public interface CP {


/**

 * @param arg4
 * @param arg3
 * @param arg2
 * @param arg1
 * @param arg0
 * @return
 *     returns java.lang.String
 */
@WebMethod
@WebResult(partName = "return")
@Action(input = "GUI/CP/getResultsRequest", output = "GUI/CP/getResultsResponse")
public String getResults(
    @WebParam(name = "arg0", partName = "arg0")
    String arg0,
    @WebParam(name = "arg1", partName = "arg1")
    String arg1,
    @WebParam(name = "arg2", partName = "arg2")
    String arg2,
    @WebParam(name = "arg3", partName = "arg3")
    String arg3,
    @WebParam(name = "arg4", partName = "arg4")
    String arg4);

}

问题已解决：我必须像这样嵌入小程序

<applet archive="client.jar" code="gui.MainApplet" width="1600" height="1400"></applet>

我不得不签署我的小程序（仍然不知道为什么）。
