Failure to access native display from a browser on port 5800

[Yat-sang Kwong]

Hello, James:

Thanks for suggestion.  I am not sure how to set the httpd parameter in 
vnc.so.  I am now starting vnc using the vncserver script file.

1)  I am not sure how to set the httpd parameter in vnc.so.  Could you 
advise how to do that?
2)  I am now starting vnc using the vncserver script file.  Could the httpd 
parameter be set in the vncserver script file?
3)  Please note that right now I can use a browser to access desktop 1 with 
http://myvncserver:5801 (after starting it with "vncserver :1").  So the 
java class files must be accessible already and since my apache web server 
is not running, these java classes must be served by the vnc builtin http 
server already.  I am puzzled as to why I cannot access desktop 0 with 
http://myvncserver:5800

Thanks.
