запуск апплета через муравья из затмения

/ 11 августа 2010

Я хотел бы запустить апплет в build.xml, например так: 

<java classname="sun.applet.AppletViewer" classpath="${libraries}">
</java>

(по крайней мере, так работает в netbeans)

но я получаю сообщение об ошибке: 

 [java] JVM args ignored when same JVM is used.
 [java] Could not find sun.applet.AppletViewer. Make sure you have it in your classpath

 [java] Java Result: -1

похоже, что аргумент classpath = "..." переопределяет путь по умолчанию для eclipse-ant. к сожалению, мне действительно нужно указать дополнительный путь к классу.

Попробуйте использовать параметр fork. 

<java classname="sun.applet.AppletViewer" classpath="${libraries}" fork="true">

Создаст новый процесс JVM и запустит ваш апплет.

Это прекрасно работает: 

<project default="test">

<target name="test">
    <java classname="sun.applet.AppletViewer">
        <arg value="http://java.sun.com/applets/jdk/1.4/demo/applets/BarChart/example1.html"/>
    </java>
</target>

</project>
