| 10 | <h2>Installing the Java Plug-in</h2> |
|---|
| 11 | <br> |
|---|
| 12 | <p> |
|---|
| 13 | |
|---|
| 14 | The Laj and Maj applets are written for Java 1.2 (a.k.a. |
|---|
| 15 | J2SE 1.2), and theoretically any web browser that fully supports |
|---|
| 16 | this (or any higher version) should work. However, for best |
|---|
| 17 | compatibility we recommend that you download and install the official |
|---|
| 18 | <b>Java Plug-in</b> software from Sun Microsystems. |
|---|
| 19 | This plug-in generally works with a variety of web browsers, |
|---|
| 20 | including Internet Explorer, Netscape, and Mozilla. |
|---|
| 21 | <p> |
|---|
| 22 | The main overview page for the Java Plug-in product is |
|---|
| 23 | <a href="http://java.sun.com/products/plugin/"> |
|---|
| 24 | http://java.sun.com/products/plugin/</a>, and an assortment |
|---|
| 25 | of download links is available at |
|---|
| 26 | <a href="http://java.sun.com/j2se/downloads/"> |
|---|
| 27 | http://java.sun.com/j2se/downloads/</a>. |
|---|
| 28 | Sun also provides a simplified download facility (latest version |
|---|
| 29 | only), which is accessible via the "Download NOW" button at |
|---|
| 30 | <a href="http://java.com/">http://java.com/</a>. |
|---|
| 31 | For details about exactly which platforms are supported, see |
|---|
| 32 | <a href="http://java.sun.com/j2se/1.5.0/system-configurations.html"> |
|---|
| 33 | http://java.sun.com/j2se/1.5.0/system-configurations.html</a>. |
|---|
| 34 | <p> |
|---|
| 35 | The plug-in is |
|---|
| 36 | usually bundled with the Java 2 Runtime Environment (JRE) and the |
|---|
| 37 | Java 2 Software Development Kit (JDK/SDK). If you are given a choice |
|---|
| 38 | between these, either will do; the JRE is smaller because it |
|---|
| 39 | doesn't include developer tools, but both of them contain the |
|---|
| 40 | plug-in. Note that even though Laj does not currently use any Java |
|---|
| 41 | features beyond 1.2, as of this writing it is compiled with version |
|---|
| 42 | 1.3.1 of Sun's SDK, so running it with the corresponding version |
|---|
| 43 | (or higher) of the plug-in is recommended. We have, however, |
|---|
| 44 | observed some drawing anomalies with the 1.4.x series on some |
|---|
| 45 | platforms (including "phantom repeats" in the symbol panel and |
|---|
| 46 | failure to draw the zoom box and crosshairs), so you may want to |
|---|
| 47 | stick with 1.3.x or 1.5.x. |
|---|
| 48 | <p> |
|---|
| 49 | Each download should come with installation instructions |
|---|
| 50 | (read them!), but here are some additional platform-specific |
|---|
| 51 | tips. |
|---|
| 52 | <p> |
|---|
| 53 | |
|---|
| 54 | <h3>Windows</h3> |
|---|
| 55 | <p> |
|---|
| 56 | We recommend that you <b>delete any previously installed versions</b> |
|---|
| 57 | of the plug-in, JRE, JDK, and/or |
|---|
| 58 | SDK before you install the new one, to avoid getting them mixed. |
|---|
| 59 | For example, in Windows 98 you can do this by opening the Start |
|---|
| 60 | menu and choosing Settings - Control Panel - Add/Remove Programs, |
|---|
| 61 | then selecting from the list the items you want to uninstall. |
|---|
| 62 | After the new installation is complete, you may need to close |
|---|
| 63 | and restart your browser to make it recognize the new plug-in, |
|---|
| 64 | or even reboot your computer. |
|---|
| 65 | <p> |
|---|
| 66 | Note that versions of Sun's Java above 1.3.x will not work on |
|---|
| 67 | Windows 95. |
|---|
| 68 | <p> |
|---|
| 69 | |
|---|
| 70 | <h3>Macintosh</h3> |
|---|
| 71 | <p> |
|---|
| 72 | Currently Sun does not have a Java Plug-in for Macs, but Mac OS X |
|---|
| 73 | ships with a sufficiently recent version of Java already included, |
|---|
| 74 | and further updates may be available via Apple's Software Update |
|---|
| 75 | mechanism (depending on your version of OS X). We have observed |
|---|
| 76 | display anomalies in some versions (e.g., red circle has a black |
|---|
| 77 | background), but Laj et al. should still be usable. |
|---|
| 78 | For Mac OS Classic, Apple has a Java runtime called MRJ 2.2.5, but |
|---|
| 79 | unfortunately it only supports Java 1.1.8 (not Java 1.2) and thus |
|---|
| 80 | will not work with our applets. |
|---|
| 81 | <p> |
|---|
| 82 | For more information about Java on the Mac, see |
|---|
| 83 | <a href="http://www.apple.com/java/"> |
|---|
| 84 | http://www.apple.com/java/</a> and |
|---|
| 85 | <a href="http://developer.apple.com/java/"> |
|---|
| 86 | http://developer.apple.com/java/</a>. |
|---|
| 87 | <p> |
|---|
| 88 | |
|---|
| 89 | <h3>Linux</h3> |
|---|
| 90 | <p> |
|---|
| 91 | Sun now provides versions of the Java Plug-in for Linux, in |
|---|
| 92 | either RPM or self-extracting binary format. |
|---|
| 93 | Be sure to read the installation notes first, |
|---|
| 94 | for system requirements and detailed instructions. |
|---|
| 95 | <p> |
|---|
| 96 | |
|---|
| 97 | <h3>Solaris</h3> |
|---|
| 98 | <p> |
|---|
| 99 | Note that Solaris 8 already includes Java 1.2, though you may |
|---|
| 100 | want to install a newer version. Sun provides versions of the |
|---|
| 101 | Java Plug-in for Solaris on both Sparc and x86 processors. |
|---|
| 102 | Be sure to read the installation notes first, |
|---|
| 103 | for system requirements and detailed instructions. In particular, |
|---|
| 104 | note that you may need to apply some Solaris patches to your |
|---|
| 105 | system before installing Java, and possibly obtain additional |
|---|
| 106 | fonts. You might also want to uninstall any previous versions of |
|---|
| 107 | the plug-in, JRE, JDK, and/or SDK to avoid getting them mixed. After |
|---|
| 108 | the installation, you may need to close and restart your browser |
|---|
| 109 | to make it recognize the new plug-in. |
|---|
| 110 | <p> |
|---|
| 111 | One last bit of advice: at one point during our installation, |
|---|
| 112 | we were instructed to enter the command <tt>xhost +</tt> , |
|---|
| 113 | but this is a <b>bad idea</b> because it seriously compromises your |
|---|
| 114 | system security. If this message appears, we recommend using proper |
|---|
| 115 | security protocols instead. |
|---|
