Hi All
I want to set parameters of an applet (Applet2) and I don't want to use
HTML tags to do this. I want to load "Applet2" from "Applet1" and
everything is Ok but I can't find a way to pass parameters from Applet1
code to Applet2. If there were a setParameter(key,val) htere was no
problem ....
Can anybody help me please ?

Why not? What have you got against HTML?

>..I want to load "Applet2" from "Applet1"

In the same web page?

In different frames of the same web page?

In different browsers - coming off different sites -
displayed on different computers?

Have you checked the API docs? They are often helpful
in circumstances such as this.

Possibly.. that depends on you and how hard
you are prepared to work.

[ Of course, anybody else can feel free to jump in and
help you here - but if it is me - ..you have a lot of work
ahead of you. And you'll need to direct your questions to
c.l.j.help. ]

HI dear Andrew
I work for a company and this company has applets written before and
dont want others to download this .class files and work offline with
them.
My task is writing an applet that can load those applets . because of
this security restrictions I cant easily load the HTML files of main
applets ( using getAppletContext().showDocument(URL) ) because popel
can download main classes from source of their HTMLs this way....

I used this code to do this :

Applet app = (Applet) Class.forName("mainClass").newInstance();
add(app);
app.setStub(this);
app.resize(getWidth(),getHeight());
app.init();
app.start();

It works fine for applets that haven't parameters
My problem is extending this code to set parameters from my applet code
for main applets
Thank U a lot 4 Ur attention

There is no solution. If you can load the applet, you can save it
and dissect it at leisure.

If both applet are willing to co-operate, applet A can call methods of
Applet B once it finds it.

It can find it either by doing a new SomeOtherApplet or if it already
running somewhere else on the page you write code like this which
comes from CurrCon. The applets share information about what currency
the user likes and all update to his latest choice.

for ( Enumeration other=getAppletContext().getApplets();
other.hasMoreElements(); )
{
Object otherApplet = other.nextElement();
{ if ( otherApplet instanceof CurrCon )
{
CurrCon otherCurrConApplet = (CurrCon) otherApplet;
// I suspect Applets will be on this list that have not
finished
// executing init.
otherCurrConApplet.currencyChangeListener();
}
}
}
