Hola Juan Carlos,

sorry, I'm not sure how up to date CVS is. I suppose, there have been left old files. With the very 
latest version, you will not need hmiFake or hmiFake2.java. The "fake features" have been moved 
into hmiFakeCI.java.
hmiD.java has been replaced by hmiDesigner.java. 
Please adapt your Makefile/script for not to compile the obsolete targets.

Some demos are NOT up to date, e.g. hmiInput.html.
But hmiLinearDial is, so you may use these lines from it as an example how it should look:

<applet code="hmiViewer.class" codebase="./" width=640 height=480>
<param name="communicator" value="hmiFakeCI">
This will use the fakeCI that fakes values for my demo pages on visual.sourceforge.net

Alternatives are:
<param name="communicator" value="hmiVisualCI">
This is used to really communicate with VISUAL's server.
<param name="communicator" value="hmiNoCI">
This is to be used with hmiDesigner. It just creates a variable for each variable/coodinate 
requested by the widgets and sets it's value to zero. Value can be changed by connecting a 
potentiometer to the same variable.

There must be something new in JAVA 1.4???
I do not have it at hand. Try to insert an empty method like:
void setStream(java.lang.String S,java.io.InputStream IS) {
}
and see what it does or does not.

About pageViewer and later versions PV2 and PV3:
They are very experimental. 
You do not need them if you use the applets in a browser or with an appletviewer. They are trial 
versions to make links work via the showDocument method without using a browser. appletviewer 
does not implement showDocument.
Further, appletviewer opens a new frame for each applet if called with multiple applets in the 
same HTML file.
My aim with these things is to provide a lightweight extended appletviewer which can change 
pages, display multiple applets in a common window and maybe display text and a subset of html 
tags from the HTML page.
This could eliminate the need for a browser on small systems.
I just took the code from Kaffe's (www.kaffe.org) appletviewer and modified it.
I'm using JDK 1.1.8 mostly.

I will update CVS this weekend, I hope.
HTH
Thomas
