Hello,

I can't make method showDocument to work.

This works:
applet.getAppletContext().showDocument(new
URL("http://www.google.com"), "_self");

But I want to show page from my disk:
applet.getAppletContext().showDocument(new URL(getCodeBase() +
"PanoramaTrain.html"), "_self");
This does not work, it just don't show any page.

Please help, i am in hurry :(

What with pop-up blockers, you simply cannot
rely on showDocument to work out on the real
World Wide Web at all.

Did you check the Java console of your browser?

Please pay money for consultancy if it is urgent.
OTOH, this is usenet, so 'cool your jets, Sparky'.

Andrew's warning is a good one - he and I spent a lot of time dealing with
the pop-up blocker issue. Since I use signed applets I was able to find a
good workaround, but otherwise it is hard to rely on using showDocument.

I can think of two possible problems:
1. File name format - your form may be right but be sure to check.
2. Sometimes you need "Mark of the Web" in your files, which requires a
line like:

to be placed at the start of your HTML file that you want to pop up (the
0028 is the total of characters in the string so if the URL is longer it
needs to be a higher number). I forget when you really need this but this
was one of the workarounds that people needed for some situations when
Windows XP SP2 came out. Searching on "Mark of the Web" should give more
details.

hello,

i just can't figure it out. Is there maybe another method to change
document in a browser?

Greetings

No other method is necessary for *your* browser. The problem here
is almost certainly security, since your applet (in your browser) can
showDocument a page on the net without problems.
