The preparations are as follows:
Download

http://jaist.dl.sourceforge.net/sourceforge/jython/jython_installer-2.2.1.jar
http:// mmmysql.sourceforge.net/dist/mm.mysql-2.0.4-bin.jar
installation (jdk/jre needs to be installed?)
java -jar jython_installer-2.2.1.jar Install to C:jython2.2.1
to install zxJDBC Unzip .jar to c:tmp
Copy mm.mysql-2.0.4-bin.jar to c:tmp
C:jython2.2.1>set CLASSPATH=c:tmpmm.mysql-2.0.4- bin.jar;c:tmpzxJDBC.jar;%CLASSPATH%
Start the mysql server C:mysql51>cd bin
C:mysql51bin>mysqld --console
And create the database C:mysql51bin>mysql -u root

You need to use jython's own encapsulated dbexts library
and finally edit a file named dbexts.ini and save it to c:jython2.2.1lib
[default]
name=mysqltest
[jdbc]
name=mysqltest
url=jdbc:mysql://localhost/test
user=root
pwd=
driver=org.gjt.mm.mysql.Driver
Enter jython
>>> from dbexts import dbexts
>>> mysqlcon = dbexts("mysqltest", "c:jython2.2.1libdbexts.ini
>>> mysqlcon.table()
