This is the preferred method for using new custom charsets.
You can create your own code tables for use in the JVM and activate them by applying the procedure described in Using other predefined code tables . Instead of a predefined JDK code table name, use your own code table name with the syntax jdk:<my_code_table>.
A detailed description on how to implement and deploy your own code tables in the Java runtime environment can be found in the Java documentation at
http://docs.oracle.com/javase/8/docs/api/java/nio/charset/package-summary.html
and in the BeanConnect JavaDoc for the package net.fsc.beanta.encoding.
A Java sample code is present in the BeanConnect delivery scope in the package net.fsc.beanconnect.encoding.sample.
In order to use your own code tables, you have to place the classes in the directory <JDK>/jre/lib/ext. Further information is available in "Java Extension Mechanism".
