Tomcat6用JNDI连接Sql2005

在tomcat6与tomcat5下是不同的。tomcat5下的网上到处都是,不说了。呵呵
1.在项目的WebRoot/META-INF/下建立 content.xml文件
文件内容为:<Context reloadable="true">
 <Resource name="jdbc/test" auth="Container"
              type="javax.sql.DataSource" driverClassName="net.sourceforge.jtds.jdbc.Driver"
              url="jdbc:jtds:sqlserver://localhost:1433;instance=SQLEXPRESS;DatabaseName=test"
              username="sa" password="123456" maxActive="200" maxIdle="30"
              maxWait="-1"/>
</Context>
2.在Dao中这样调用就可以了:

import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.sql.DataSource;


private DataSource dataSource;
Context ctx;
  try
  {
   ctx = new InitialContext();
   dataSource=(DataSource)ctx.lookup("java:comp/env/jdbc/test");
  }
  catch (NamingException e)
  {
   e.printStackTrace();
  }
Connection conn=null;
  PreparedStatement pstmt=null;
  ResultSet rs=null;
  try
  {
   conn=getDataSource().getConnection();
}
  catch (SQLException e)
  {
   throw e;
  }
  finally
  {
   closeResultSet(rs);
   closePreparedStatement(pstmt);
   closeConnection(conn);
  }
