Installing the Java Plug-in
The Laj and Maj applets are written for Java 1.2 (a.k.a.J2SE 1.2), and theoretically any web browser that fully supportsthis (or any higher version) should work. However, for bestcompatibility we recommend that you download and install the officialJava Plug-in software from Sun Microsystems.This plug-in generally works with a variety of web browsers,including Internet Explorer, Netscape, and Mozilla.The main overview page for the Java Plug-in product ishttp://java.sun.com/products/plugin/, and an assortmentof download links is available athttp://java.sun.com/j2se/downloads/.Sun also provides a simplified download facility (latest versiononly), which is accessible via the “Download NOW” button athttp://java.com/.For details about exactly which platforms are supported, seehttp://java.sun.com/j2se/1.5.0/system-configurations.html.The plug-in isusually bundled with the Java 2 Runtime Environment (JRE) and theJava 2 Software Development Kit (JDK/SDK). If you are given a choicebetween these, either will do; the JRE is smaller because itdoesn”t include developer tools, but both of them contain theplug-in. Note that even though Laj does not currently use any Javafeatures beyond 1.2, as of this writing it is compiled with version1.3.1 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 someplatforms (including “phantom repeats” in the symbol panel andfailure to draw the zoom box and crosshairs), so you may want tostick with 1.3.x or 1.5.x.Each download should come with installation instructions(read them!), but here are some additional platform-specifictips.
You are watching: No java 2 sdk, standard edition v 1.5 support for applet.
We recommend that you delete any previously installed versionsof the plug-in, JRE, JDK, and/orSDK before you install the new one, to avoid getting them mixed.For example, in Windows 98 you can do this by opening the Startmenu 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 closeand restart your browser to make it recognize the new plug-in,or even reboot your computer.Note that versions of Sun”s Java above 1.3.x will not work onWindows 95.
Currently Sun does not have a Java Plug-in for Macs, but Mac OS Xships with a sufficiently recent version of Java already included,and further updates may be available via Apple”s Software Updatemechanism (depending on your version of OS X). We have observeddisplay anomalies in some versions (e.g., red circle has a blackbackground), but Laj et al. should still be usable.For Mac OS Classic, Apple has a Java runtime called MRJ 2.2.5, butunfortunately it only supports Java 1.1.8 (not Java 1.2) and thuswill not work with our applets.For more information about Java on the Mac, seehttp://www.apple.com/java/ and http://developer.apple.com/java/.
Sun now provides versions of the Java Plug-in for Linux, ineither RPM or self-extracting binary format.Be sure to read the installation notes first,for system requirements and detailed instructions.
Note that Solaris 8 already includes Java 1.2, though you maywant to install a newer version. Sun provides versions of theJava 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 yoursystem before installing Java, and possibly obtain additionalfonts. You might also want to uninstall any previous versions ofthe plug-in, JRE, JDK, and/or SDK to avoid getting them mixed. Afterthe installation, you may need to close and restart your browserto make it recognize the new plug-in.One last bit of advice: at one point during our installation,we were instructed to enter the command xhost +,but this is a bad idea because it seriously compromises yoursystem security. If this message appears, we recommend using propersecurity protocols instead.Cathy Riemer, December 2005
