Description

Java(TM) Plug-in:Version 1.4.0
Using JRE version 1.4.0-beta2 java HotSpot(TM) Client VM
JEditorPane cannot render even the simplest HTML from a URL in the merlin-beta2.
Put the class files, HTML loader & simple.htm on a web server & try under 1.3.X
and the latest 1.4 beta2... Yields link text of simple.htm under 1.3.X and file not
found under 1.4.0 Beta2 - b77...

The HTML is not quite correct. The closing </COMMENT> tag appears to
be in the wrong place. Perhaps that is part of the problem.

I just tested on Solaris and Window NT platform, using merlin B79 and B70, both works fine without any problem. I am using Netscape 4.75
You can try it to hit my web server at following URL:
http://sarcasm.east:8888/dennis/bug/4504372/HTMLinJEP.html
The class file HTMLinJEP.class must be in the same directory as HTMLinJEP.html and simple.htm, this probably a user error.

This is a bug in Java plugin 1.4
It only happened when you put your HTML file diretly under DocumentRoot dir of your web server. getCodeBase() didn't return correct vlaue.
I have put a fix in AppletViewer.java file. It will solve the problem.

I'm thinking it might not be related to 4456393 because you
can substitute:
sampleURL = new URL(getCodeBase()+"simple.htm");
with a hard-coded URL (no codebase ref) of your choice,
provide the applet the appropriate rights, and HTML will
still not render in the JEP. Also, my tests show that
plaintext files, eg:
sampleURL = new URL(getCodeBase()+"sample.txt");
render fine in the JEP... Think its more of a central HTML
rendering issue...

Re: "The HTML is not quite correct. The closing </COMMENT>
tag appears to be in the wrong place. Perhaps that is part
of the problem." - OK, but that's in the applet calling
HTML & not the HTML to be rendered... When you fix the
COMMENT problem does the bug go away?
PLEASE NOTE: JDK6 is formerly known as Project Mustang
