 The JNI library for JAVA is built automatically if required JNI header files are detected by the [[configure]] script. Make sure that the [[javac]] command is included in the [[PATH]] environment variable. The JAVA class files are built with the [[javac]] command detected as well. The {ant,http://ant.apache.org} utility from the Apache Software Foundataion can be used to build the java class files. The [[build.xml]] file is provided at the top-level directory.
