Tomcat5.0数据源的配置

第一：如果应用没有发布到tomcat的webapps目录下，可以先在conf的server.xml下注册全局的数据源

<?xml version='1.0' encoding='utf-8'?>
<Server>
<Listener className="org.apache.catalina.mbeans.ServerLifecycleListener"/>
<Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener"/>
<GlobalNamingResources>
<Environment name="simpleValue" type="java.lang.Integer" value="30"/>
<Resource auth="Container" description="User database that can be updated and saved" name="UserDatabase" type="org.apache.catalina.UserDatabase"/>
<Resource name="DJPTDataSource" type="javax.sql.DataSource"/>

<ResourceParams name="UserDatabase">
<parameter>
<name>factory</name>
<value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
</parameter>
<parameter>
<name>factory</name>
<value>org.apache.catalina.users.MemoryUserDatabaseFactory</value>
</parameter>
<parameter>
<name>pathname</name>
<value>conf/tomcat-users.xml</value>
</parameter>
</ResourceParams>

<ResourceParams name="DJPTDataSource">
<parameter>
<name>factory</name>
<value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
</parameter>
<parameter>
<name>driverClassName</name>
<value>oracle.jdbc.driver.OracleDriver</value>
</parameter>
<parameter>
<name>url</name>
<value>jdbc:oracle:thin:@127.0.0.1:1521:oracle</value>
</parameter>
<parameter>
<name>username</name>
<value>djpt</value>
</parameter>
<parameter>
<name>password</name>
<value>djpt</value>
</parameter>
<parameter>
<name>maxActive</name>
<value>20</value>
</parameter>
<parameter>
<name>maxIdle</name>
<value>10</value>
</parameter>
<parameter>
<name>maxWait</name>
<value>10000</value>
</parameter>
</ResourceParams>

</GlobalNamingResources>
<Service name="Catalina">
<Connector acceptCount="100" connectionTimeout="20000" disableUploadTimeout="true" port="8800" redirectPort="8443" maxSpareThreads="75" maxThreads="150" minSpareThreads="25">
</Connector>
<Connector port="8009" protocol="AJP/1.3" protocolHandlerClassName="org.apache.jk.server.JkCoyoteHandler" redirectPort="8443">
</Connector>
<Engine defaultHost="localhost" name="Catalina">
<Host appBase="webapps" name="localhost">
<Logger className="org.apache.catalina.logger.FileLogger" prefix="localhost_log." suffix=".txt" timestamp="true"/>
</Host>
<Logger className="org.apache.catalina.logger.FileLogger" prefix="catalina_log." suffix=".txt" timestamp="true"/>
<Realm className="org.apache.catalina.realm.UserDatabaseRealm"/>
</Engine>
</Service>
</Server>
然后在conf/Catalina/localhost下建立与应用同名的.xml文件进行数据源的引用

内容如下：

<?xml version='1.0' encoding='utf-8'?>
<Context displayName="DJPT" docBase="E:/mye6.0_workbench/DJPT/WebRoot" path="/DJPT" privileged="true" reloadable="true" workDir="work/Catalina/localhost/DADJPT">
<ResourceLink global="DJPTDataSource" name="DJPTDataSource" type="javax.sql.DataSource"/>
</Context>

第二:如果采用发布形式，则在conf目录下的context.xml文件里

<?xml version='1.0' encoding='utf-8'?>
<Context>
<WatchedResource>WEB-INF/web.xml</WatchedResource>

<Resource name="DJPTDataSource"
auth="Container"
type="javax.sql.DataSource"
driverClassName="oracle.jdbc.driver.OracleDriver"
url="jdbc:oracle:thin:@127.0.0.1:1521:ORCL"
username="djpt"
password="djpt"
maxActive="50"
maxIdle="10"
maxWait="5000" />

</Context>
