Why is getWindow() not able to be resolved?

问题:

I can't resolve the getWindow(); method for some reason...

import java.applet.Applet;

import netscape.javascript.JSObject;

public class Class466 {
public static void method6020(Applet applet, String string, int i)
        throws Throwable {
    try {
        JSObject.getWindow(applet).eval(string);
    } catch (RuntimeException runtimeexception) {
        throw Class346.method4175(runtimeexception, new StringBuilder()
                .append("tf.a(").append(')').toString());
    }
}

public static Object method6021(Applet applet, String string, short i)
        throws Throwable {
    try {
        return JSObject.getWindow(applet).call(string, null);
    } catch (RuntimeException runtimeexception) {
        throw Class346.method4175(runtimeexception, new StringBuilder()
                .append("tf.f(").append(')').toString());
    }
}

public static Object method6022(Applet applet, String string,
        Object[] objects, byte i) throws Throwable {
    try {
        return JSObject.getWindow(applet).call(string, objects);
    } catch (RuntimeException runtimeexception) {
        throw Class346.method4175(runtimeexception, new StringBuilder()
                .append("tf.b(").append(')').toString());
    }
}

Class466() throws Throwable {
    throw new Error();
}
}

In jdk1.7.0_11 I noticed that there are two separate jars within ../jre/lib/ that contain the netscape.javascript.JSObject.class, namely jfxrt.jar and plugin.jar. In the case of my IDE (IntelliJ), when I created a project SDK for Java it added both the jfxrt and the plugin jars to the classpath. As the jfxrt.jar appears alphabetically before plugin.jar in the classpath, my application code was not resolving JSObject.getWindow(...) properly. As we're not using JavaFX within our application I simply removed the jfxrt.jar from my projects Java SDK classpath.

Is the "MAYSCRIPT" applet tag parameter declared ?

<APPLET code="XYZApp.class" codebase="html/" align="baseline"
 width="200" height="200" MAYSCRIPT>

I think you have to add:

import java.awt.Window;
import java.awt.event.WindowEvent
