struts 链接sqlserver2000数据库出了些问题，请大家帮忙解决一下。

Question

就是在运行到DBUser的connect = dataSource.getConnection();这一步时卡在那里运行不下去了。Console栏里一直反复的出现这种信息：
2006-4-10 16:10:15 org.apache.struts.legacy.GenericDataSource getConnection
信息:    Check for timeout, activeCount=0, useCount=0
2006-4-10 16:10:15 org.apache.struts.legacy.GenericDataSource getConnection
信息:    Sleep until next test   
.......

Answer 1

我怀疑是这个的问题
key="org.apache.struts.action.DATA_SOURCE"

Answer 2

<data-source　中也没指定type属性及其值

Answer 3

data-source 的设置问题  你自己好好看看API
我现在在网吧 没有API可查

Answer 4

现在我在<data-source key="org.apache.struts.action.DATA_SOURCE">中加上了 type="org.apache.commons.dbcp.BasicDataSource"变成
<data-source key="org.apache.struts.action.DATA_SOURCE" type="org.apache.commons.dbcp.BasicDataSource">
在lib中也加上了commons-dbcp-1.2.1.jar包，可是运行后显示如下错误：exception javax.servlet.ServletException: Servlet.init() for servlet action threw exception
