Most people use the Java compiler (javac) provided by Sun Microsystems (or, on some Linux distros, the Blackdown one (
http://www.blackdown.org)) instead of GCJ shipped by GNU which lacks a lot of things at present.
You can find the official Java compiler from java.sun.com. Or better still you may have a RPM for the Java SDK including javac shipped by Red hat. Search for it and install it.
Then just
javac MyClass.java
as usual. If you know Java this should not look foreign to you.

DACS.JAVA(7) DACS Miscellaneous Information DACS.JAVA(7)
NAME
dacs.java - DACS Java support
DESCRIPTION
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 dacs.install(7)[1].
Note
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 allocation.
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
DIAGNOSTICS
The return codes are as documented in the command's manual page.
