tomcat5.0与tomcat5.5连接池数据源的配置区别
问题：
当出现如下错误：
Cannot create JDBC driver of class '' for connect URL 'null'
应该考虑如下两种不同导致的错误。
?1、?tomcat5.5的配置方式
?
????? <Context path="/ggsbase"?? debug="0" reloadable="true" crossContext="true">
??????? <Resource name="jdbc/hiDataSource2" auth="Container" type="javax.sql.DataSource"
?????????????? maxActive="10" maxIdle="5" maxWait="10000"
?????????????? username="ggsbase" password="abc" driverClassName="com.oscar.Driver"
?????????????? url="jdbc:oscar://172.24.186.17:2003/OSRDB"/>
??????? <Resource name="jdbc/hiDataSource3" auth="Container" type="javax.sql.DataSource"
?????????????? maxActive="10" maxIdle="5" maxWait="10000"
?????????????? username="ggsbase" password="hgjhgj" driverClassName="com.oscar.Driver"
?????????????? url="jdbc:oscar://172.24.186.17:2003/OSRDB"/>
?
?????? </Context>

2、tomcat5.0
?<Context path="/ggsbase" debug="0" reloadable="true" crossContext="true">
<Resource name="jdbc/hiDataSource2" auth="Container" type="javax.sql.DataSource"/>
<ResourceParams name="jdbc/hiDataSource2">
<parameter>
<name>driverClassName</name>
<value>com.oscar.Driver</value>
</parameter>
<parameter>
<name>maxActive</name>
<value>50</value>
</parameter>
<parameter>
<name>maxIdle</name>
<value>5</value>
</parameter>
<parameter>
<name>maxWait</name>
<value>10000</value>
</parameter>
<parameter>
<name>username</name>
<value>hgj</value>
