Tomcat在debian升级到squeeze后不能启动的问题

刚刚把Debian升级到sqeuuze，却发现tomcat不能启动了。
启动日志部分如下

一开始看到Network is unreachable的错误，以为是主机名设置问题。添加了主机名到IP的解析，还是不行。。。再怀疑是JDK的问题，可是无论是自己下载Sun JDK的bin安装，还是使用debian package，还是使用OpenJDK，都不行...
最后Google，终于找到问题所在，IPv6的问题。
有两个解决办法：
1、让操作系统也支持IPv4

sudo sed -i 's/net.ipv6.bindv6only\ =\ 1/net.ipv6.bindv6only\ =\ 0/' \
/etc/sysctl.d/bindv6only.conf && sudo invoke-rc.d procps restart

2、给Java定制参数选项：

JAVA_OPTS="$JAVA_OPTS -Djava.net.preferIPv4Stack=true"
