首先要编辑/etc/apt/source，添加网络镜像以下载最新的包。
例如：
deb http://ftp.gtlib.gatech.edu/debian/ lenny main contrib non-free
deb-src http://ftp.gtlib.gatech.edu/debian/ lenny main contrib non-free
接下来安装JDK6，因为debian使用了里外的java虚拟机，因此需要配置一下系统。

debian-lenny:/home/fxu# /usr/sbin/update-alternatives --config java
There are 4 alternatives which provide `java'.
Selection Alternative
-----------------------------------------------
1 /usr/bin/gij-4.3
+ 2 /usr/lib/jvm/java-gcj/jre/bin/java
3 /usr/bin/gij-4.1
4 /usr/lib/jvm/java-6-sun/jre/bin/java
Press enter to keep the default[], or type selection number: 4
Using '/usr/lib/jvm/java-6-sun/jre/bin/java' to provide 'java'.
debian-lenny:/home/fxu# /usr/sbin/update-alternatives --config javac
There is only 1 program which provides javac
(/usr/lib/jvm/java-6-sun/bin/javac). Nothing to configure.
debian-lenny:/home/fxu# java -version
java version "1.6.0_07"
Java(TM) SE Runtime Environment (build 1.6.0_07-b06)
Java HotSpot(TM) Client VM (build 10.0-b23, mixed mode, sharing)
我使用了如下的软件（版本可能会不同）：
jdk-6u7-nb-6_1-linux-ml.sh
sjsas-9_1_01-mysql-linux.bin
sailfin-installer-v1-b37i-linux.jar
将jdk-6u7-nb-6_1-linux-ml.sh，sjsas-9_1_01-mysql-linux.bin添加可执行属性，chmod u+x filename。然后运行 ./filename就可以了。
因为我在虚拟机上操作，在安装sailfin的时候出现如下错误：
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
这时候需要用如下命令：
java -Xms32m -Xmx400m -jar sailfin-installer-v1-b37i-linux.jar
期间还需要安装libstdc++5：
apt-get install libstdc++5
至此，一套环境算是构建完毕，可以用Java进行SIP开发了。
