tomcat下JNDI配置

前两天在tomcat配置jndi上花费了挺长时间，后来才发现原来很简单，只是自己在获取Connection连接时方法不对，汗~~

 

1.在server.xml中的配置：

    

  <GlobalNamingResources>   
	<Resource
      auth="Container"
      description="User database that can be updated and saved"
      name="UserDatabase"
      type="org.apache.catalina.UserDatabase"
      pathname="conf/tomcat-users.xml"
      factory="org.apache.catalina.users.MemoryUserDatabaseFactory"/>
  </GlobalNamingResources>

 

   

<Host appBase="webapps" autoDeploy="flase" name="localhost" unpackWARs="true" xmlNamespaceAware="false" xmlValidation="false">
      	<Context
            docBase="E:\workspace\**\webapp"
            path="/echannel"
            reloadable="true"
            debug="5" 
            crossContext="true">
          <Resource
                  name="jdbc/ds0"
                  type="javax.sql.DataSource"                  
                  driverClassName="oracle.jdbc.driver.OracleDriver"
                  maxIdle="2"
                  maxWait="5000"
                  username="test"
                  password="test"
                  url="jdbc:oracle:thin:@192.168.1.103:1521:orcl"
                  maxActive="4"/>  		
           <Resource
                  name="jdbc/ds1"
                  type="javax.sql.DataSource"                  
                  driverClassName="oracle.jdbc.driver.OracleDriver"
                  maxIdle="2"
                  maxWait="5000"
                  username="test1"
	  password="test1"
                  url="jdbc:oracle:thin:@192.168.1.104:1521:orcl"
                  maxActive="4"/>    		
        </Context>
</Host>

 

 

2.页面中获取连接：

 

 

Context initContext = new InitialContext();
Context envContext  = (Context)initContext.lookup("java:/comp/env");
DataSource ds = (DataSource)envContext.lookup("jdbc/ReportTest");
Conection conn = ds.getConnection();
