使用 JNLP 启动具有 Java3D 依赖项的小程序时出现问题

正如标题所述,目前正在尝试使用 JNLP 作为为系统上未安装 Jave3D 的任何用户启动具有 Java3D 依赖项的小程序的方法。不幸的是,当小程序尝试启动时,出现与未找到“subapplet.classname”值有关的错误。

java.net 网站 FourByFour Demo 上提供的示例无法正常工作,这一事实使问题变得更加复杂。因未找到类的相同问题而失败。

带有四乘四演示的 Java JNLP 网页:

java.net FourByFour 演示

已尝试过Firefox 和IE 浏览器没有区别。java.net

网站上使用的代码示例:

<applet code="org.jdesktop.applet.util.JNLPAppletLauncher"
        width=800 height=400
        archive="http://download.java.net/media/java3d/webstart/test/j3d-examples.jar,
                 http://download.java.net/media/applet-launcher/applet-launcher.jar,
                 http://download.java.net/media/java3d/webstart/release/j3d/latest/j3dcore.jar,
                 http://download.java.net/media/java3d/webstart/release/j3d/latest/j3dutils.jar,

                 http://download.java.net/media/jogl/builds/archive/jsr-231-webstart-current/jogl.jar,
                 http://download.java.net/media/gluegen/webstart/gluegen-rt.jar">
    <param name="codebase_lookup" value="false">
    <param name="subapplet.classname" value="org.jdesktop.j3d.examples.four_by_four.FourByFour">
    <param name="subapplet.displayname" value="Java 3D Four by Four Applet">
    <param name="jnlpNumExtensions" value="1">
    <param name="jnlpExtension1" value="http://download.java.net/media/java3d/webstart/release/java3d-latest.jnlp">
    <param name="progressbar" value="true">
    <param name="noddraw.check" value="true">
</applet>

As title says currently trying to use JNLP as a means of launching an applet with Java3D dependenices for any user who may not have Jave3D installed on their system. Unfortunately getting an error to do with the 'subapplet.classname' value not being found, while the applet tries to launch..

This problem is compounded by the fact that the example supplied on the java.net website FourByFour Demo isn't working and fails with the same problem of class not found.

Java JNLP webpage with Four by Four Demo:

Have tried with both Firefox & IE browsers with no difference..

Sample of the code used on the java.net website:

<applet code="org.jdesktop.applet.util.JNLPAppletLauncher"

Java 3D applet 示例仍然使用“org.jdesktop.applet.util.JNLPAppletLauncher”。自 JRE 版本 1.6.0_21-b07 起,此启动器无法正常工作并且不再维护。

遵循“Java 教程:使用 Applet 标签进行部署”h ttp://download-llnw.oracle.com/javase/tutorial/deployment/applet/html.html 我切换到 applet 标签和相应的 jnlp 文件在我的网页上。这需要 JRE 6u10+。以下示例是实时的,可以从此处启动:

Applet incl。加载 Java 3D

<applet codebase="webstart/" width="1200" height="800" align="middle">
 <param name="jnlp_href" value="propellerUniverseAPP1.0_J3D.jnlp">
</applet>

JNLP

<?xml version="1.0" encoding="UTF-8"?>
<!-- InteractiveMesh.org TestSpace PropellerUniverse 1.0 Applet J3D -->

<jnlp spec="1.0+" codebase="http://www.interactivemesh.org/testspace/webstart/" 
    href="propellerUniverseAPP1.0_J3D.jnlp">

        <description>PropellerUniverse 1.0</description>
        <!-- icon href=""/ -->
    </information>

    <security> </security>

    <update check="always" policy="always"/>

    <resources>
        <j2se version="1.6+"/>
        <extension href="http://download.java.net/media/java3d/webstart/release/java3d-latest.jnlp"/>
        <jar href="propellerUniverse1.0.jar" main="true"/>
        <jar href="jim_j3d-vrml97_v2.1.jar"/>
        <jar href="orbitbehaviorinterim2.1.jar"/>
        <property name="sun.awt.noerasebackground" value="true"/>  
        <property name="sun.awt.erasebackgroundonresize" value="true"/>  
        <property name="sun.java2d.noddraw" value="true"/>  
    </resources>
    <applet-desc  main-class="com.interactivemesh.j3d.testspace.canvas3d.PropellerUniverseJApplet"
                  width="1200" height="800" name="PropellerUniverse">
    </applet-desc>
</jnlp>

另请参阅:

the Java 3D applet examples still use the 'org.jdesktop.applet.util.JNLPAppletLauncher'. Since JRE-Version 1.6.0_21-b07 this launcher doesn't work properly and is no longer maintained.

Following the 'The Java Tutorial : Deploying With the Applet Tag' h ttp://download-llnw.oracle.com/javase/tutorial/deployment/applet/html.html I switched to the applet-tag and a corresponding jnlp-file on my webpages. This requires JRE 6u10+. The following sample is live and can be launched from here:
