类未注册：org.apache.tomcat.dbcp.dbcp.SQLNestedException
出错频率高，持续时间短（几分钟后系统就正常了），这个问题始终未解决：
1、配置文件如下
<Resource name="x3Sys" url="jdbc:jtds:sqlserver://...:.../XXXDB"
username="XXX"
password="XXX"
maxIdle="50"
MaxActive="2000"
maxWait="5000"
removeAbandoned="true"
removeAbandonedTimeout="50"
driverClassName="net.sourceforge.jtds.jdbc.Driver"
auth="Container"
type="javax.sql.DataSource" />
2、日志文件部份内容

3、在线连接数无取查证（使用的是Tomcat服务，jconsole无法连接成功）
4、执行http://ip:port/x3/bizserver。 ... 显示http错误”
因持续时间短，最终用户反馈给我时，系统基本已经正常了，故无从取证 |
