Download Java

Download Java version 8 (it's free). You can use either

  • Java SE Runtime Environment
     if you want just the minimum necessary to run Java with APL
     you do not have to write any Java to use the new features
  • Java SE Development Kit
     if you also want to write and compile your own Java tools for use with APL
       just write a static Java method according to the interface procedures
       compile it
       include the directory with the *.class in the APL preferences in the Java Class Path(s) (see below)


  • Install Java from the downloaded file
 note the name of the directory where you installed Java, like
   C:\Program Files\Java\jre1.8.0_151

  • Install the version of NARS2000 APL with support for Java
 note the name of the directory where you installed APL, like
   C:\Program Files\NARS2000\AplJava

Start Up

Start APL, and enable support for Java Three locations will need to be specified in the preferences

 1 under the Java installation directory
   containing the file jvm.dll
     this depends on whether you installed the JRE or the JDK, like either
       C:\Program Files\Java\jre1.8.0_151\bin\server\jvm.dll
       C:\Program Files\Java\jdk1.8.0_151\jre\bin\server\jvm.dll
 2 under the APL installation directory
     Java Preferences
       Select a version #
       Enter the Path to ... JVM.DLL ...
         C:\Program Files\Java\jre1.8.0_141\bin\server\jvm.dll
       Enter the Java Class Path(s) ...
         C:\Program Files\NARS2000\AplJava\sm
       Enter the Java Session Manager Path.
         C:\Program Files\NARS2000\AplJava\session
       check  Use Java-based Session Manager
   click either OK or Apply
     the new Session Manager should start
       you can leave either by
         closing the old Session Manager window

The next time you start APL, the new session manager will automatically start.
