<h2>Installing the Java Plug-in</h2>
|
|
<br>
|
|
<p>
|
|
|
|
The Laj and Maj applets are written for Java 1.2 (a.k.a.
|
|
J2SE 1.2), and theoretically any web browser that fully supports
|
|
this (or any higher version) should work. However, for best
|
|
compatibility we recommend that you download and install the official
|
|
<b>Java Plug-in</b> software from Sun Microsystems.
|
|
This plug-in generally works with a variety of web browsers,
|
|
including Internet Explorer, Netscape, and Mozilla.
|
|
<p>
|
|
The main overview page for the Java Plug-in product is
|
|
<a href="http://java.sun.com/products/plugin/">
|
|
http://java.sun.com/products/plugin/</a>, and an assortment
|
|
of download links is available at
|
|
<a href="http://java.sun.com/j2se/downloads/">
|
|
http://java.sun.com/j2se/downloads/</a>.
|
|
Sun also provides a simplified download facility (latest version
|
|
only), which is accessible via the "Download NOW" button at
|
|
<a href="http://java.com/">http://java.com/</a>.
|
|
For details about exactly which platforms are supported, see
|
|
<a href="http://java.sun.com/j2se/1.5.0/system-configurations.html">
|
|
http://java.sun.com/j2se/1.5.0/system-configurations.html</a>.
|
|
<p>
|
|
The plug-in is
|
|
usually bundled with the Java 2 Runtime Environment (JRE) and the
|
|
Java 2 Software Development Kit (JDK/SDK). If you are given a choice
|
|
between these, either will do; the JRE is smaller because it
|
|
doesn't include developer tools, but both of them contain the
|
|
plug-in. Note that even though Laj does not currently use any Java
|
|
features beyond 1.2, as of this writing it is compiled with version
|
|
1.3.1 of Sun's SDK, so running it with the corresponding version
|
|
(or higher) of the plug-in is recommended. We have, however,
|
|
observed some drawing anomalies with the 1.4.x series on some
|
|
platforms (including "phantom repeats" in the symbol panel and
|
|
failure to draw the zoom box and crosshairs), so you may want to
|
|
stick with 1.3.x or 1.5.x.
|
|
<p>
|
|
Each download should come with installation instructions
|
|
(read them!), but here are some additional platform-specific
|
|
tips.
|
|
<p>
|
|
|
|
<h3>Windows</h3>
|
|
<p>
|
|
We recommend that you <b>delete any previously installed versions</b>
|
|
of the plug-in, JRE, JDK, and/or
|
|
SDK before you install the new one, to avoid getting them mixed.
|
|
For example, in Windows 98 you can do this by opening the Start
|
|
menu and choosing Settings - Control Panel - Add/Remove Programs,
|
|
then selecting from the list the items you want to uninstall.
|
|
After the new installation is complete, you may need to close
|
|
and restart your browser to make it recognize the new plug-in,
|
|
or even reboot your computer.
|
|
<p>
|
|
Note that versions of Sun's Java above 1.3.x will not work on
|
|
Windows 95.
|
|
<p>
|
|
|
|
<h3>Macintosh</h3>
|
|
<p>
|
|
Currently Sun does not have a Java Plug-in for Macs, but Mac OS X
|
|
ships with a sufficiently recent version of Java already included,
|
|
and further updates may be available via Apple's Software Update
|
|
mechanism (depending on your version of OS X). We have observed
|
|
display anomalies in some versions (e.g., red circle has a black
|
|
background), but Laj et al. should still be usable.
|
|
For Mac OS Classic, Apple has a Java runtime called MRJ 2.2.5, but
|
|
unfortunately it only supports Java 1.1.8 (not Java 1.2) and thus
|
|
will not work with our applets.
|
|
<p>
|
|
For more information about Java on the Mac, see
|
|
<a href="http://www.apple.com/java/">
|
|
http://www.apple.com/java/</a> and
|
|
<a href="http://developer.apple.com/java/">
|
|
http://developer.apple.com/java/</a>.
|
|
<p>
|
|
|
|
<h3>Linux</h3>
|
|
<p>
|
|
Sun now provides versions of the Java Plug-in for Linux, in
|
|
either RPM or self-extracting binary format.
|
|
Be sure to read the installation notes first,
|
|
for system requirements and detailed instructions.
|
|
<p>
|
|
|
|
<h3>Solaris</h3>
|
|
<p>
|
|
Note that Solaris 8 already includes Java 1.2, though you may
|
|
want to install a newer version. Sun provides versions of the
|
|
Java Plug-in for Solaris on both Sparc and x86 processors.
|
|
Be sure to read the installation notes first,
|
|
for system requirements and detailed instructions. In particular,
|
|
note that you may need to apply some Solaris patches to your
|
|
system before installing Java, and possibly obtain additional
|
|
fonts. You might also want to uninstall any previous versions of
|
|
the plug-in, JRE, JDK, and/or SDK to avoid getting them mixed. After
|
|
the installation, you may need to close and restart your browser
|
|
to make it recognize the new plug-in.
|
|
<p>
|
|
One last bit of advice: at one point during our installation,
|
|
we were instructed to enter the command <tt>xhost +</tt> ,
|
|
but this is a <b>bad idea</b> because it seriously compromises your
|
|
system security. If this message appears, we recommend using proper
|
|
security protocols instead.
