resin连接池配置

resin的conf下有一个配置文件resin.conf，里面有一个接连池的例子，是连MySql的。我用的是SQL Server，所以就在例子上做了点改动，改动后内容如下：
<!--
- Sample database pool for SQL Server
- The JDBC name is java:comp/env/jdbc/sql
-->
<database>
<jndi-name>jdbc/sql</jndi-name>
<driver type="com.microsoft.jdbc.sqlserver.SQLServerDriver">
<url>jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=test</url>
<user>sa</user>
<password></password>
</driver>
<prepared-statement-cache-size>8</prepared-statement-cache-size>
<max-connections>20</max-connections>
<max-idle-time>30s</max-idle-time>
</database>
然后建一个测试网页test.jsp
<%@ page import="java.sql.*"%>
<%@ page import="javax.sql.*"%>
<%@ page import="javax.naming.*"%>
<%
    DataSource ds = null;
    try{
    InitialContext ctx=new InitialContext();
    ds=(DataSource)ctx.lookup("java:comp/env/jdbc/sql");
    Connection conn = ds.getConnection();
    Statement stmt = conn.createStatement();
    String strSql = " select * from test";
    ResultSet rs = stmt.executeQuery(strSql);
    while(rs.next()){
       out.println(rs.getString(1)+"<br>");                
      }
  
    rs.close();
    stmt.close();
    conn.close();
    }
    catch(Exception ex){
     ex.printStackTrace();
     out.print(ex.getMessage());
    }
%>
测试成功，相当顺利！
再配一个连接Oracle的连接池：
<!--
- Sample database pool for Oracle
-
- The JDBC name is java:comp/env/jdbc/ora
-->
  <database>
    <jndi-name>jdbc/ora</jndi-name>
    <driver type="oracle.jdbc.driver.OracleDriver">
      <url>jdbc:oracle:thin:@10.32.88.88:1521:ckkh</url>
      <user>ckkh</user>
      <password>ckkhdba</password>
     </driver>
     <prepared-statement-cache-size>8</prepared-statement-cache-size>
     <max-connections>20</max-connections>
     <max-idle-time>30s</max-idle-time>
   </database>
