NAME - DACS Java support


       This document describes support for Java provided by DACS.

       To enable Java support, DACS must be configured using the --enable-java flag. It may also
       be necessary to specify the location of the Java commands and include files. See

           Java support is currently very limited and should be considered experimental. It is
           currently only possible to call dacsauth(1)[2] and dacscheck(1)[3] using the Java
           Native Interface (JNI) provided. The command line arguments to both of these commands
           are exactly as documented in their manual pages. Each argument is passed as a String.

           The code is not thread-safe and is probably not suitable for being called many times
           within a particular process due to assumptions it makes about dynamic memory

           There are no immediate plans to improve or extend Java support. Using the existing
           capability to build the JNI layer, however, it should not be difficult for an
           experienced Java programmer to build upon the example Java code provided.

       With Java support enabled, building DACS will copy the JNI shared library and a .jar file
       to the library directory (default: /usr/local/dacs/lib), and the JNI include files to the
       include directory (default: /usr/local/dacs/include).

       The tools/java/jni distribution directory contains a simple script called javarun that
       demonstrates how to run dacsauth or dacscheck as a Java application. For example, to
       validate the Unix password for user somebody, run (as root):

           ./javarun dacsauth -m unix suff -user somebody -prompt


       The return codes are as documented in the command's manual page.
