Tomcat 5.5 下配置root context

被折腾了半天，把结果备忘下:

 

    <!-- Global JNDI resources -->
    <GlobalNamingResources>

        <!-- Test entry for demonstration purposes -->
        <Environment name="simpleValue" type="java.lang.Integer" value="30"/>

        <!-- Editable user database that can also be used by
    UserDatabaseRealm to authenticate users -->
        <Resource name="UserDatabase" auth="Container"
                  type="org.apache.catalina.UserDatabase"
                  description="User database that can be updated and saved"
                  factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
                  pathname="conf/tomcat-users.xml"/>

        <Resource name="jdbc/portal" auth="Container"
                  type="javax.sql.DataSource" driverClassName="oracle.jdbc.driver.OracleDriver"
                  url="jdbc:oracle:thin:@172.18.33.211:1521:urpdb"
                  username="gzgz" password="gaga" maxActive="20" maxIdle="10"
                  maxWait="-1"/>

    </GlobalNamingResources>

 

 

 

 <Host name="localhost" appBase="webapps"
                  unpackWARs="true" autoDeploy="true"
                  xmlValidation="false" xmlNamespaceAware="false">        
                 
                 
                          <Context path="" docBase="/opt/apache-tomcat-5.5.28/cmstar"  debug="0" reloadable="true" crossContext="true">
    <ResourceLink
   name="jdbc/portal"
   type="javax.sql.DataSource"
   global="jdbc/portal"/>  
</Context>

 

</Host>

 

上面的context只能在server.xml配置，配置在conf/Catalina/localhost/ROOT.xml下无效（有人提到这种配置办法，但我试了不行，居然还会报数据源相关的错误）

 

把webapps下的ROOT目录干掉，并且应用中web.xml：

 

    <resource-ref>
        <description>Database for Portal</description>
        <res-ref-name>jdbc/portal</res-ref-name>
        <res-type>javax.sql.DataSource</res-type>
        <res-auth>Container</res-auth>
        <res-sharing-scope>Unshareable</res-sharing-scope>
    </resource-ref>
