JavaView runs on any computer and operating system which has a web browser
with a valid Java_1.1 installation. The currently downloadable browser
versions at Microsoft and Netscape are fine. For older versions see below.
The browser installation on Win/NT PCs and Macintosh computers usually do
all necessary Java installations. On UNIX systems some additional setup might
be necessary for each user, for example, a correct CLASSPATH - please,
consult your system operator.
In Case of Problems
The initial download of the JavaView archive may need some time on slow
connections. Between 300KB and 500KB must be transferred over the network
until JavaView starts. This archive is transferred once. Other JavaView
applets do not require a new download of the archive but use the version of
the browser's cache.
General Rules
If there is no applet or geometry visible after some time, try the
following steps:
- Browser Version: On MS-Windows and Unix assure that you
have a browser with version number
Microsoft Internet Explorer 4.01
and later
Netscape Navigator 4.08 and later.
On Apple Macintosh, see below in the MacOS.
If you do not know your browser's version number, go to the following
page which will list your browser
properties.
- Enable Java: If you do not see the message
"JavaView initializing ..." after some time, then your
browser could not start JavaView. Maybe Java is not enabled in your
browser, so check the menu entry
Edit-Preferences-Advanced
in Netscape or Extras-Internet Options-Advanced in
Microsoft Internet Explorer whether your browser is Java enabled.
- Security Issues: If you do not see the message
"JavaView initializing ..." after some time, there might be a
security issue. Try open the Java Console of your browser via menu
Communicator-Java
Console or Communicator-Tools-Java Console or View-Java
Console and look for the word Security. (Remark: on
MS Internet Explorer the console must be enabled in the Preferences.)
Security issues are a bit delicate for beginners to understand and you
might want to ask an expert who knows about your operating system and
the security policy. This has nothing to do with JavaView.
Windows Family
-
Important Hint on javaview.exe: On MS-Windows, if you have an
older version of the virtual machine then you will receive an error
message when executing javaview.exe. Please, either upgrade the Internet
Explorer which will also upgrade the JVM, or directly download a newer JVM
from Microsoft.
Linux:
- kaffe: for LINUX versions, we were told that the standalone version of JavaView
does not run correctly under kaffe 1.04
but it seems to run ok with kaffe 1.05.
This seems to be a bug in those implementations of Java.
- Problems with window sizes
and popup-menus:
Sun's JRE1.3.0_x and JRE1.3.1 on Linux with KDE 2.x, RedHat 7.1 or SuSE 7.2 sometimes has problems with window sizes
and popup-menus. New windows open in arbitrary dimensions and popup-menus may not
open at all or don't show any text or doesn't have any effect.
Possible solutions:
- Java Runtime: you must have the
Macintosh Runtime for Java (MRJ) 2.1 or later. For more information see the page.
