1, with database software (such as: MySQL) to create a database, the database registered with the database name is just the data created
Library, if it is a data source name, ODBC configuration is required.
2, the driver will be placed in the D:/tomcat 5.5/common/lib or the corresponding development tools of the LIB,
For D:/tomcat 5.5/conf/web.xml modifications, open Web.xml, add the following in front of </web-app>:
<resource-ref>
<description>db connection</description>
<res-ref-name>jdbc/mysql</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
Navigate through the folder to D:/tomcat 5.5/conf/catalina/localhost, and find your Web application corresponding to the. XML text
Pieces, such as Root.xml, and add code to the bottom of this file:
