ant demo.start - Could not create connection to database

[perl]

Hello,

I am missing an detailed INSTALL procedure, however I tried to follow these steps to set up an demo instance:
http://activiti.org/userguide/index.html#demo.setup

OS is  Debian Testing amd64 on ESX.
# java -version
java version "1.6.0_22"
Java(TM) SE Runtime Environment (build 1.6.0_22-b04)
Java HotSpot(TM) 64-Bit Server VM (build 17.1-b03, mixed mode)

tomcat version 6.0.28-9 is running and listening on port 8080

mysqld version 5.1.49-3 is running and listening on  127.0.0.1:3306
User activiti created with access to db activiti

| GRANT USAGE ON *.* TO 'activiti'@'localhost' IDENTIFIED BY PASSWORD '*D5467AF2C8A3ECE7ACF4EFE59E829CF76B8ABB05' |
| GRANT ALL PRIVILEGES ON `activiti`.* TO 'activiti'@'localhost'                                                  |

libmysql-java 5.1.10+dfsg-2 installed.

I unziped activiti-5.0.zip to /root/activiti2 and changed to directory setup
and modified properties

# egrep -v "^#|^ *$" build.properties
db=mysql
tx=standalone
tomcat.version=6.0.28
feature.cycle=enabled
feature.modeler=enabled

# egrep -v "^#|^ *$" build.mysql.properties
db=mysql
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/activiti?autoReconnect=true
jdbc.username=activiti
jdbc.password=activiti

I did not set JAVA_HOME and ANT_HOME environment variables since I have no clue what they should be set to.
Now I get this error:

# ant demo.start

I have no idea why this happens because "mysql -h 127.0.0.1 -u activiti -pactiviti activiti" just works fine.
If I do the "ant demo.start" I do not see any connections attemps to 127.0.0.1:3306

Help is much appreciated

Found the problem, activity was trying to access mysql using ipv6
but mysql is not listening to ipv6

Disabling of ipv6 by

sysctl -w net.ipv6.conf.all.disable_ipv6=1"

helped.
