Hi There,
I'm having some problems printing a
java applet that uses a jar file. I have signed and verified signing
with verisign certificate. When I try to print the applet I get the following error in the IE java console
window:
got frame

One site I read said that I has to convert my HTML files using Sun's html converter so I tried this
but now when I try to print I the printer dialog box comes up but I get the following error in the Java
console window and a blank page is printed (you can see here it's not even getting the frame)
Exception occurred during event dispatching:

Please help!! I have to use 1.1.8 in this example and this code also has to work on the MAC. Am
I going to have to use a Java Plugin and is there one available for the MAC? Any information/help
you can provide will be greatly appreciated. Here is my
test code:
public class testapp extends Applet implements ActionListener {
private Button print;
public void init() {
print=new Button("print");
print.addActionListener(this);
add(print);
}
//get the browser frame (to use as the owner when creating a dialog)
private Frame getBrowserFrame() {
Container c = this.getParent();
while (c != null) {
if (c instanceof Frame) {
System.out.println("got frame");
return((Frame)c);
}
c = c.getParent();
}
return ((Frame)c);
}
public void actionPerformed(ActionEvent e) {
PrintJob pj = getToolkit().getPrintJob(getBrowserFrame(), "printing" , null);
if (pj != null) {
System.out.println("got print job");
Graphics pg = pj.getGraphics();
System.out.println("after got graphics");
if (pg!=null) {
System.out.println("got graphics");
printComponents(pg);
System.out.println("printed components");
pg.dispose();
System.out.println("dispose graphics");
} else {
System.out.println("graphics is null");
}
pj.end();
} else {
System.out.println("printjob is null");
}
System.out.println("ending printing");
}
}
Thanks,
Naomi
