У меня есть апплет, встроенный в страницу http. Апплет подписан (как и все jar-файлы, которые я использую) и использует новый плагин java, который позволяет встраивать апплеты в веб-страницу с помощью jnlp.
Я хотел лениво загрузить один из jar-файлов, требуемых моим апплетом, но я не могу заставить его работать.
Это мой файл jnlp:
<?xml version="1.0" encoding="UTF-8"?>
<jnlp spec="1.0+" href="/GUI.jnlp">
<information>
<title>My Applet</title>
<vendor>My Company</vendor>
</information>
<resources>
<j2se href="http://java.sun.com/products/autodl/j2se" version="1.6+"/>
<jar href="/mainGUI.jar" main="true"/>
<jar href="/external_1.jar"/>
<jar href="/external_2.jar"/>
<jar href="/external_3.jar" download="lazy"/>
</resources>
<applet-desc
name="My Applet"
main-class="com.xformation.GUIAppletMain"
width="800"
height="600">
</applet-desc>
</jnlp>
И HTML-файл:
<APPLET width="100%" height="100%" name="My App" code="CompatibilityApplet" archive="mainGUI.jar">
<param name="jnlp_href" value="GUI.jnlp">
<script type="text/javascript">
<!--
document.write('<param name="server_address" value="' + window.location.href + '">');
//-->
</script>
</APPLET>
Также в файле mainGUI.jar у меня есть правильный файл INDEX, сгенерированный ant:
<target name="-do-jar-with-manifest" depends="compile">
<jar destfile="${dist.jar}" basedir="${build.classes.dir}" index="true">
<indexjars>
<fileset dir="libs">
<include name="**/external_1.jar"/>
<include name="**/external_2.jar"/>
<include name="**/external_3.jar"/>
</fileset>
</indexjars>
</jar>
</target>
Из того, что я вижу, файл mainGUI.jar даже не загружается первым веб-браузером (на самом деле он последний), поэтому файл INDEX нельзя правильно использовать для проверки файлов, которые следует загрузить.
Есть идеи, что я делаю не так?

Одно обновление:
Поскольку я запускаю этот пример на своем собственном веб-сервере, я запустил его с помощью отладчика и просто пропустил обслуживающую библиотеку, которая должна загружаться лениво (я только что возвратил пустой файл).
Тогда я получил эту ошибку:
java.io.FileNotFoundException: http://192.168.22.124:6500/axis.jar?version-id=1.0

Строка, которая мне кажется очень подозрительной:

Так что, похоже, все ленивые загрузки просто игнорируются? Вопрос почему?
