PoolMan怎样配置啊，有没有人会啊？？？(88分)

我把POOLMAN目录放到D盘，把poolman.jar和poolman.props、jdbc2_0-stdext.jar都放到classpath中，在poolman.props中加入如下代码：
##mssqlserver distribution
db_name.5=mssqlserver
db_driver.5=com.inet.tds.TdsDriver
db_url.5=jdbc:inetdae:127.0.0.1:1433?database=JSP&charset=GB2312&sql7=true
db_username.5=sa
db_password.5=
initialConnections.5=3
enableCache.5=true
cacheSize.5=5
cacheRefresh.5=10000
connection_timeout.5=15000
checkfrequency.5=30000
usertimeout.5=10000
maximumsize.5=20

其中db_url.5=jdbc:inetdae:127.0.0.1:1433?database=JSP&charset=GB2312&sql7=true 的JSP是我的数据库名，不知道我这样配置对吗，但我执行
java com.codestudio.sql.PoolMan "mssqlserver"时出现错误：
Attemption to connect to mssqlserver... could not find 'poolman.props' --now attemptiong to read deprecated file name 'pool.props'...failed.
FAILED.
Test Failed with the following error:
java.sql.SQLExcetpion:

到底错哪了，poolman.props已经加到classpath中了，还要配置其他的吗，急死了，帮帮忙了啊？？？？？？

poolman.props的问题解决了，现在的问题是：
Attemption to connect to mssqlserver... failed.
Test Failed with the following error:
java.sql.SQLException:ERROR:Unable to use the specified initial connections
at com.codestudio.sql.PoolMan.connect(PoolMan.java:140)

Exception in thread "main" java.lang.NullPointerException at com.codestudio.sql.PoolMan.main(PoolMan.java:63)

是连接不上数据库，是poolman.props有问题？？
