SSH 框架中，连接DB2 数据库的问题
具体的配置如下
<bean id="dataSource"
class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName"
value="COM.ibm.db2.jdbc.app.DB2Driver">
</property>
<property name="url" value="jdbc:db2:db_wsc"></property>
<property name="username" value="db2admin"></property>
<property name="password" value="db2admin"></property>
</bean>
运行TOMCAT，出现如下错误

上网查了一下午，各种方法都试遍了，比如将db2javajar拷到TOMCAT/LIB下，将db2jdbc.dll栲到jdk/bin目录下，都试了，就是出现这个错误，希望哪为大虾帮帮小弟吧，郁闷啊~~
[解决办法]
你在客户端安装db2 的客户端了？
jdbc:db2:db_wsc 这样写是用的type2。
[解决办法]
driverClassName="com.ibm.db2.jcc.DB2Driver"
url="jdbc:db2://xx:50000/db_wsc
用这个试一下
