Hi,
Here is part of my serer.xml:
<Context ...>
<Resource name="jdbc/MyDB" auth="Container"
type="javax.sql.DataSource"/>
<ResourcesParams name="jdbc/MyDB">
<parameter>
<name>driverClassName</name>
<value>com.microsoft.jdbc.sqlserver.SQLServerDriver</value>
</parameter>
...
</ResourcesParams>
</Context>
when I try to use the datasource in my servlet, I got:
java.sql.SQLException: Cannot load JDBC driver class 'null' at
