Install Xvnc

Installation of Xvnc is quite straightforward; you unpack the archive and then copy the relevant files into some local

bin directory, e.g. /usr/local/bin. (Note that some modern Linux distributions  already have Xvnc installed.)

Copying of the Xvnc binaries is shown below.

[server1]$ cp vncviewer vncserver vncpasswd vncconnect Xvnc 

/usr/local/bin

Launch Xvnc

Launching Xvnc is also quite straightforward; this should be done as the user that will be running webMathematica,

for example,  the user tomcat. The first time Xvnc is launched, it asks for a password.  In the example below, the

server is launched as display :1. 

[server1]$ su tomcat

[server1]$ vncserver

You will require a password to access your desktops.

Password:

Verify:

New X  desktop is server1:1

Creating default startup script /home/tomcat/.vnc/xstartup

Starting applications specified in /home/tomcat/.vnc/xstartup

Log file is /home/tomcat/.vnc/server1.wolfram.com:1.log

Test Xvnc

Once it is launched, it is a good idea to test the server by running an application to use it, for example, the Mathemat 

ica front end. This is shown below.

[server1]$ su tomcat

[server1]$ mathematica  display :1

Of course, when this is done, you do not see an actual window on your screen; this is because it is a virtual server.

To  see  the  window  from  the  Mathematica  front  end,  you  can  run  the  vncviewer.  This  can  be  done  as  shown

below.

[server1]$ vncviewer :1

This should show you a screen with the front end window visible. You should be able to type into the front end and

see it working. At any time webMathematica is running, you can view the desktop with vncviewer.
