Tomcat5.0安装版数据源的配置

在Tomcat5.0的配置中我们可以通过Admin的后台来手动配置JNDI数据源也可以通过修改配置文件的方式来实现数据源的配置，在conf目录下修改server.xml文件在<Host>标签中加入数据源的配置信息

   <Context path="/ycportal" docBase="ycportal" debug="0" reloadable="true" crossContext="true">
     
     
        <Logger   className="org.apache.catalina.logger.FileLogger"  
         prefix="localhost_DBTest_log."   suffix=".txt"  
         timestamp="true"/>  
      
        <Resource name="jdbc/webpublish" auth="Container" type="javax.sql.DataSource"/>
      
        <ResourceParams name="jdbc/webpublish">
      
        <parameter>
      
        <name>maxActive</name>
      
        <!-- Maximum number of DB connections in pool.Set to 0 for no limit. -->
      
        <value>10</value>
      
        </parameter>
      
        <parameter>
      
        <name>maxIdle</name>
      
        <!-- Maximum number of idle DB connections to retain in pool.Set to 0 for no limit. -->

        </parameter>
      
        <parameter>
      
        <name>maxWait</name>
      
        <!-- Maximum time to wait for a DB connection to become available in ms.An exception is thrown if this timeout is exceeded.Set to -1 to wait indefinitely. -->
      
        <value>10000</value>
      
        </parameter>
      
        <parameter>
      
        <name>removeAbandoned</name>
      
        <!-- Abandoned DB connections are removed and recycled -->
      
        <value>true</value>
      
        </parameter>
      
        <parameter>
      
        <name>removeAbandonedTimeout</name>
      
        <!-- Use the removeAbandonedTimeout parameter to set the number of seconds a DB connection has been idle before it is considered abandoned. -->
      
        <value>60</value>
      
        </parameter>
      
        <parameter>
      
        <name>username</name>

        <value>net.sourceforge.jtds.jdbc.Driver</value>
      
      
        </parameter>
      
        <parameter>
      
        <name>url</name>
      
        <!-- Database Address -->

      
        <value>jdbc:jtds:sqlserver://localhost/webdb</value>
      
      
        </parameter>
      
        </ResourceParams>
      
       </Context>

把应用需要的数据库的驱动Drivers包，和启动时需要的jar报拷贝到common目录下的lib目录中就可以了，因为Tomcat的版本不同数据源的配置上存在很大差异，不能一概而论，我这里是使用的Tomcat5.0的安装版本，JDK为1.5。
