以MS SQLServer2000为例
1.先把JDBC驱动拷贝到tomcat的common\lib目录下.
2.在tomcat的conf目录下,打开server.xml文件,找到</Host>,在它上面添加以下内容:
<Context path="/app" docBase="E:\workspace3.0\mypro\web" debug="5" reloadable="true" crossContext="true">
<Logger className="org.apache.catalina.logger.FileLogger" prefix="localhost_DBTest_log." suffix=".txt" timestamp="true"/>
<!-- Oracle -->
<Resource name="jdbc/bn" auth="Container" type="javax.sql.DataSource"/>
<ResourceParams name="jdbc/bn">
<parameter>
<name>factory</name>
<value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
</parameter>
<parameter>
<name>driverClassName</name>
<value>com.microsoft.jdbc.sqlserver.SQLServerDriver</value>
</parameter>
<parameter>
<name>url</name>
<value>jdbc:microsoft:sqlserver://127.0.0.1:1433;DatabaseName=mypro</value>
</parameter>
<parameter>
<name>username</name>
<value>sa</value>
</parameter>
<parameter>
<name>password</name>
<value></value>
</parameter>
<parameter>
<name>maxActive</name>
<value>20</value>
</parameter>
<parameter>
<name>maxIdle</name>
<value>10</value>
</parameter>
<parameter>
<name>maxWait</name>
<value>1</value>
</parameter>
</ResourceParams>
</Context>
相信都看的懂的!
3 新建一个JSP文件,添加以下代码:
<%@ page import="javax.naming.Context" %>
<%@ page import="javax.sql.DataSource"%>
<%@ page import="javax.naming.InitialContext"%>
<%@ page import="java.sql.*"%>
<%
DataSource ds = null;
try{
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
ds = (DataSource)envCtx.lookup("jdbc/myoracle");
if(ds!=null){
out.println("Connection is OK!");
Connection **=*s.getConnection();
if(cn!=null){
out.println("cn is Ok!");
Statement stmt = cn.createStatement();
ResultSet rst = stmt.executeQuery("select * from BOOK");
out.println("<p>rst is Ok!" + rst.next());
while(rst.next()){
out.println("<P>BOOK_CODE:" + rst.getString(1));
}
cn.close();
}else{
out.println("rst Fail!");
}
}
else
out.println("Fail!");
}catch(Exception ne){ out.println(ne);
}
%>
最后，进入测试。运行tomcat.bat,打开IE在地址栏中输入：http://localhost:8080\myapps\test.jsp
数据库连接池配置完毕!
