求sqlserver 2005 数据库连接解决问题。

现在我的本机是用的sqlserver2000版本的(可以正常的连接)。数据连接如下：proxool.xml
XML code:

<?xml version="1.0" encoding="UTF-8"?>
<something-else-entirely>
<proxool>
<alias>aaa</alias>
<driver-url>jdbc:jtds:sqlserver://localhost:1433/aaa</driver-url>
<driver-class>net.sourceforge.jtds.jdbc.Driver</driver-class>
<driver-properties>
<property name="user" value="sa"/>
<property name="password" value="sa"/>
</driver-properties>
<minimum-connection-count>10</minimum-connection-count> <!-- default 5 -->
<maximum-connection-count>100</maximum-connection-count> <!-- default 15 -->
<prototype-count>5</prototype-count> <!-- default 0 -->
<maximum-active-time>300000</maximum-active-time> <!-- default 300000 -->
<house-keeping-sleep-time>60000</house-keeping-sleep-time> <!-- default 30000 -->
<house-keeping-test-sql>select getdate()</house-keeping-test-sql>
</proxool>
</something-else-entirely>


现在我要把该连接改一下，升级到
