带有自定义 DownloadServiceListener 的 JNLP Applet版本控制

发布于 2024-11-30 22:55:29 字数 12243 浏览 0 评论 0原文

当我同时使用带有自定义 DownloadServiceListener 的 JNLP 小程序以及版本化的 jar 文件时，我遇到了问题。

项目结构如下：

/
+ WEB-INF/
|        + lib/
|        |    + jnlp-servlet.jar
|        + web.xml
+ lib/
|    + progress-0.1.jar
|    + MyApplet-1.0.jar
|    + applet.jnlp
|    + version.xml
+ index.jsp

我的 web.xml 的内容：

<?xml version="1.0" encoding="UTF-8"?>
<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_2_5.xsd"
           version="2.5">

    <!-- JNLP download servlet-->
    <servlet>
        <servlet-name>JnlpDownloadServlet</servlet-name>
        <servlet-class>jnlp.sample.servlet.JnlpDownloadServlet</servlet-class>
        <load-on-startup>2</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>JnlpDownloadServlet</servlet-name>
        <url-pattern>/lib/*</url-pattern>
    </servlet-mapping>

</web-app>

我的 applet.jnlp 文件如下所示：

<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="6.0+" codebase="$$codebase" href="$$name">
    <information>
        <title>MyApplet</title>
        <vendor>My AG</vendor>
        <homepage href="http://www.nowhere.com"/>
        <description>XYZ</description>
    </information>
    <update check="always" policy="always"/>
    <resources>
        <j2se href="http://java.sun.com/products/autodl/j2se" version="1.6+" initial-heap-size="128m" max-heap-size="128m"/>
        <property name="jnlp.versionEnabled" value="true"/>

    <jar href="progress.jar" version="0.1" download="progress"/>
    <jar href="MyApplet.jar" version="1.0" main="true"/>

    </resources>
    <applet-desc name="MyApplet"
                 main-class="test.MyApplet"
                 width="800" height="600"
                 progress-class="progress.CustomProgress">
        <param name="bgcolor" value="28,28,28"/>
        <param name="textcolor" value="255,222,123"/>
    </applet-desc>
</jnlp>

为了显示小程序，我使用以下 JSP 文件 (index.jsp)：

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
  <head><title>Simple jsp page</title></head>
  <body style="margin: 0;">

    <object width="100%" vspace="0" hspace="0" height="100%" align="top" name="MyApplet"
            classid="clsid:CAFEEFAC-0016-0000-0026-ABCDEFFEDCBA" onerror="alert('Invalid Java Version..')">
        <param value="MyApplet" name="name">
        <param value="application/x-java-applet;jpi-version=1.6.0_26" name="type">

        <param value="true" name="mayscript">
        <param value="false" name="scriptable">
        <param value="lib/applet.jnlp" name="jnlp_href">
        <param value="true" name="progressbar">
        <param value="238,244,248" name="boxbgcolor">
        <param value="255,255,255" name="boxfgcolor">

        <param value="false" name="classloader_cache">
        <param value="true" name="separate_jvm">
        <comment>
            <embed width="100%" vspace="0" hspace="0" height="100%" align="top" separate_jvm="true"
                   classloader_cache="false" java_arguments="-Djnlp.packEnabled -Xms256m -Xmx256m"
                   boxmessage="Loading MyApplet - please wait" boxfgcolor="255,255,255"
                   boxbgcolor="238,244,248" progressbar="true"
                   pluginspage="http://java.sun.com/products/plugin/index.html#download"
                   jnlp_href="lib/applet.jnlp" scriptable="false" mayscript="true"
                   archive="lib/MyApplet-1.0.jar" code="test.MyApplet.class"
                   type="application/x-java-applet;jpi-version=1.6.0_26"
                   name="MyApplet" onerror="alert('Invalid Java version')">
        </comment>
    </object>
</body>
</html>

以及用于版本映射的文件 ( version.xml)：

<?xml version="1.0"?>
<jnlp-versions>
  <resource>
    <pattern>
      <name>MyApplet.jar</name>
      <version-id>1.0</version-id>
    </pattern>
    <file>MyApplet-1.0.jar</file>
  </resource>
  <resource>
    <pattern>
      <name>progress.jar</name>
      <version-id>0.1</version-id>
    </pattern>
    <file>progress-0.1.jar</file>
  </resource>
</jnlp-versions>

DownloadServiceListener 的实现（+/- Sun（或 Oracle）示例的精确副本（除了不使用图像）：

package progress;

import javax.jnlp.DownloadServiceListener;
import java.awt.Container;
import java.awt.Color;
import java.awt.BorderLayout;
import javax.swing.*;
import java.net.URL;
import java.applet.AppletStub;

public class CustomProgress implements DownloadServiceListener {
    Container surfaceContainer = null;
    AppletStub appletStub = null;
    JProgressBar progressBar = null;
    JLabel statusLabel = null;
    boolean uiCreated = false;

    public CustomProgress(Object surface) {
       init(surface, null);
    }

    public CustomProgress(Object surface, Object stub) {
        init(surface, stub);
    }

    public void init(Object surface, Object stub) {
        try {
            surfaceContainer = (Container) surface;
            appletStub = (AppletStub) stub;
        } catch (ClassCastException cce) {
            cce.printStackTrace();
        }
    }

    public void downloadFailed(java.net.URL url, java.lang.String version) {        
    }

    public void progress(URL url, String version, long readSoFar, long total, int overallPercent) {
        // check progress of download and update display
        updateProgressUI(overallPercent);

    }

    public void upgradingArchive(java.net.URL url, java.lang.String version, int patchPercent, int overallPercent) {
        updateProgressUI(overallPercent);
    }

    public  void validating(java.net.URL url, java.lang.String version, long entry, long total, int overallPercent) {
        updateProgressUI(overallPercent);
    }

    private void updateProgressUI(int overallPercent) {
        if (!uiCreated && overallPercent > 0 && overallPercent < 100) {
            // create custom progress indicator's UI only if 
            // there is more work to do, meaning overallPercent > 0 and < 100
            // this prevents flashing when RIA is loaded from cache
            create(); 
            uiCreated = true;            
        }
        if (uiCreated) {
            progressBar.setValue(overallPercent);
        }
    }

    private void create() {
        JPanel top = createComponents();
        if (surfaceContainer != null) {
            // lay out the loading progress indicator UI in the given Container
            surfaceContainer.add(top, BorderLayout.NORTH);
            surfaceContainer.invalidate();
            surfaceContainer.validate();
        }
    }

    private JPanel createComponents() {
        JPanel top = new JPanel();
        top.setBackground(Color.WHITE);
        top.setLayout(new BorderLayout(20, 20));

        // get applet parameter using an instance of the AppletStub class
        // "tagLine" parameter specified in applet's JNLP file
        String tagLine = "";
        if (appletStub != null) {
            tagLine = appletStub.getParameter("tagLine");
        }
        String lblText = "<html><font color=red size=+2>JDK Documentation</font><br/>" +
                            tagLine + " <br/></html>";
        JLabel lbl = new JLabel(lblText);
        top.add(lbl, BorderLayout.NORTH);

        // use JSObject.getWindow(null) method to retrieve a reference to
        // the web page and make JavaScript calls. Duke logo displayed if
        // displayLogo variable set to "true" in the web page
//        String displayLogo = "true";
//        if (displayLogo.equals("true")) {
//            lbl = new JLabel();
//            ImageIcon logo = createImageIcon("images/DukeWave.gif", "logo");
//            lbl.setIcon(logo);
//            top.add(lbl, BorderLayout.EAST);
//        }

        statusLabel = new JLabel("<html><font color=green size=-2>Loading applet...</font></html>");
        top.add(statusLabel, BorderLayout.CENTER);

        progressBar = new JProgressBar(0, 100);
        progressBar.setValue(0);
        progressBar.setStringPainted(true);
        top.add(progressBar, BorderLayout.SOUTH);

        return top;
    }

    /** Returns an ImageIcon, or null if the path was invalid. */
    protected static ImageIcon createImageIcon(String path, String description) {
        java.net.URL imgURL = CustomProgress.class.getResource(path);
        if (imgURL != null) {
            return new ImageIcon(imgURL, description);
        } else {
            System.err.println("Couldn't find file: " + path);
            return null;
        }
    }
}

最后但并非最不重要的是，我的（非常基本的）小程序

package test;

import javax.swing.*;

public class MyApplet extends JApplet {
    @Override
    public void init() {
        add(new JLabel("This is an applet .. "));
    }
}

：你可以看到，一切都保持原样尽可能简单.. :)

现在，如果我部署 Web 应用程序，然后访问文件 index.jsp，则会发生以下情况： 有两个可用的 java 控制台，一个用于“DownloadServiceListener”，另一个用于“真正的”小程序。 在第一条上，人们可以找到以下消息：

生成自定义进度时出错：java.lang.ClassNotFoundException： 进度.CustomProgress

第二个控制台为空，小程序正确显示，显示文本：“这是一个小程序..”。

我的访问日志中有以下条目： （请注意，在每次测试之前，整个 java 缓存已被清除）。

当我查看“Java 控制面板”时，会出现小程序“MyApplet”，并且所有 jar 文件均按预期加载。

当我删除“jnlp.versionEnabled”属性、跳过 jar 条目的版本参数并将版本号添加到 jar 文件名时，自定义 DownloadServiceListener 可以完美运行。

这两个东西（版本化的 jar 文件和自定义 DSL）是否有可能不能一起使用？ 我错过了什么吗？有什么想法吗？

原文

I encountered a problem, when using a JNLP applet with custom DownloadServiceListener as well as versioned jar files at the same time.

The project structure is as follows:

/
+ WEB-INF/
|        + lib/
|        |    + jnlp-servlet.jar
|        + web.xml
+ lib/
|    + progress-0.1.jar
|    + MyApplet-1.0.jar
|    + applet.jnlp
|    + version.xml
+ index.jsp

The contents of my web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<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_2_5.xsd"
           version="2.5">

        <servlet-name>JnlpDownloadServlet</servlet-name>
        <url-pattern>/lib/*</url-pattern>
    </servlet-mapping>

</web-app>

My applet.jnlp file looks as follows:

<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="6.0+" codebase="$codebase" href="$name">
    <information>
        <title>MyApplet</title>

        <param name="textcolor" value="255,222,123"/>
    </applet-desc>
</jnlp>

To display the applet, I use the following JSP-File (index.jsp):

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
  <head><title>Simple jsp page</title></head>
  <body style="margin: 0;">

                   type="application/x-java-applet;jpi-version=1.6.0_26"
                   name="MyApplet" onerror="alert('Invalid Java version')">
        </comment>
    </object>
</body>
</html>

And the file for the version mapping (version.xml):

<?xml version="1.0"?>
<jnlp-versions>
  <resource>
    <pattern>
      <name>MyApplet.jar</name>
      <version-id>1.0</version-id>
    </pattern>
    <file>MyApplet-1.0.jar</file>
  </resource>
  <resource>
    <pattern>
      <name>progress.jar</name>
      <version-id>0.1</version-id>
    </pattern>
    <file>progress-0.1.jar</file>
  </resource>
</jnlp-versions>

The implementation of the DownloadServiceListener (which is +/- an exact copy of the Sun (or Oracle) example (except that no image is used):

package progress;

import javax.jnlp.DownloadServiceListener;
import java.awt.Container;
import java.awt.Color;
import java.awt.BorderLayout;
import javax.swing.*;
import java.net.URL;
import java.applet.AppletStub;

public class CustomProgress implements DownloadServiceListener {
    Container surfaceContainer = null;
    AppletStub appletStub = null;
    JProgressBar progressBar = null;
    JLabel statusLabel = null;
    boolean uiCreated = false;

    public CustomProgress(Object surface) {
       init(surface, null);
    }

    public CustomProgress(Object surface, Object stub) {
        init(surface, stub);
    }

    public void init(Object surface, Object stub) {
        try {
            surfaceContainer = (Container) surface;
            appletStub = (AppletStub) stub;
        } catch (ClassCastException cce) {
            cce.printStackTrace();
        }
    }

And last but not least, my (very basic) applet:

package test;

import javax.swing.*;

public class MyApplet extends JApplet {
    @Override
    public void init() {
        add(new JLabel("This is an applet .. "));
    }
}

As you can see, everything is kept as simple as possible.. :)

Now, if I deploy the web application, and then access the file index.jsp, the following happens:
There are two java consoles available, one for the "DownloadServiceListener", and another for the "real" applet.
On the first, one can find the following message:

Error generating custom progress : java.lang.ClassNotFoundException:
progress.CustomProgress

The second console is empty, and the applet is correctly displayed, showing the text: "This is an applet ..".

There are the following entries in my access-log:
(Note that the whole java cache has been cleared before every test).

When I look in the "Java Control Panel", the applet "MyApplet" appears, and all jar-files were loaded as expected.

When I remove the "jnlp.versionEnabled"-property, skip the version parameters of the jar-entries, and add the version number to the jar-file-names, then the custom DownloadServiceListener works perfectly.

Is it possible, that the two things (versioned jar-files & custom DSL) can not be used together?
Did I miss something? Any ideas?
