Question

我需要通过applet打印一些信息。我的applet来自签名的qds-client.jar：

public class PrintText extends Applet  implements Printable {

 private ClientAccount clientAccount;

 public ClientAccount getClientAccount() {
     return clientAccount;
 }

 public void setClientAccount (ClientAccount clientAccount) {
     this.clientAccount = clientAccount;
 }

 public void setClientAccountFromJSON(String json) {
     this.clientAccount = toClientAccountFromJSON(json);
     System.out.println("------------------------------SetClient");
 }

 public int print(Graphics g, PageFormat format, int page) throws
         ...
 }

 public void printText() throws PrinterException {
     ...
 }

 private String getTextToPrint(ClientAccount clientAccount) throws PrinterException {
     ...
 }

 private ClientAccount toClientAccountFromJSON(String json) {
     return JsonUtils.fromJson(ClientAccount.class, json);
 }

 public void startPrint () {
     System.out.println("------------------------------------------Start");
 }
}

Accordinng JNLP：

<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="1.5+" codebase="http://localhost:10099/partials/" href="print.jnlp">
    <information>
       ....
    </information>

<resources>
    <jar href="/partials/qds-client.jar"/>
    <jar href="/partials/core-3.2.1.jar"/>
    <jar href="/partials/gson-2.3.1.jar"/>
</resources>

<applet-desc name="printText" main-class="com.qdsrest.utils.printer.PrintText" width="500" height="200"></applet-desc>

<update check="background"/>
<security>
    <all-permissions/>
</security>

和HTML标记：

<applet name="printApplet" jnlp_href="/partials/print.jnlp" width="10" height="10">
<param name="permissions" value="all-permissions"/>
</applet>

当我从js文件中调用applet的方法时：

document.printApplet.setClientAccountFromJSON({/not empty/});

我得到了

Error: Error calling method on NPObject!

在Mozilla和

Java控制台和方法中的

不起作用。为什么我会“再试一次......”？这是什么意思？方法toClientAccountFromJSON使用GSON lib gson-2.3.1.jar将JSON对象完全反序列化为Java对象。我做了什么错事？请告诉我一个正确的思考方式。

我不记得当前的细节，但很久以前，在第一次浏览器大战时，曾经有一个属性using HP.LFT.SDK.WPF;，你的applet需要与javascript交谈。

哦，参数需要是字符串：

mayscript

从JavaScript调用applet的方法
