eclipse+myeclipse+mysql+tomcat配置数据源
1 1.配置数据源（Tomcat 5.0\conf\server.xml）在</Host>添加

84 2. 修改web.xml
85
86 打开%TOMCAT_HOME%\conf\web.xml,在</web-app>的前面添加以下内容：
87
88 <resource-ref>
89 <description>DB Connection</description>
90 <res-ref-name>jdbc/mysql</res-ref-name>
91 <res-type>javax.sql.DataSource</res-type>
92 <res-auth>Container</res-auth>
93 </resource-ref>
94
95 3. JDBC驱动程序mysql-connector-java-3.0.15-ga-bin.jar放置在%TOMCAT_HOME%\common\lib和应用的WEB-INF\lib下
96
97 启动服务器前，把你的tt部署到C:\Tomcat 5.0\webapps
98 一切OK，启动你的猫猫
