c3p0使用
我想在java se的环境里面使c3p0连接池！！ 当时从官方下载下来的里面的xml配置文件是
<server>
<mbean code="com.mchange.v2.c3p0.mbean.C3P0PooledDataSource"
name="jboss:service=C3P0PooledDataSource">
<attribute name="JndiName">java:PooledDS</attribute>
<attribute name="JdbcUrl">jdbc:oracle:thin:@localhost:1521:orcl</attribute>
<attribute name="DriverClass">oracle.jdbc.driver.OracleDriver</attribute>
<attribute name="User">scott</attribute>
<attribute name="Password">123456</attribute>
<depends>jboss:service=Naming</depends>
</mbean>
</server>
请问第一个参数和最后一个参数怎么配置！！ java se的环境是不是不要配置最后一个参数！！
里面的源码的例子是：
String jndiName = args[0];
DataSource unpooled = DataSources.unpooledDataSource(
"jdbc:oracle:thin:@localhost:1521:orcl", "scott", "123456");
DataSource pooled = DataSources.pooledDataSource(unpooled);
InitialContext ctx = new InitialContext();
ctx.rebind(jndiName, pooled);
我要是不配置就报Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
这个错！！
请问下这个jndiName是个什么东西！！
import java.sql.*;import javax.naming.*;import javax.sql.DataSource;/** * This example shows how to programmatically get and directly use an unpooled * DataSource */public final class UseJndiDataSource { public static void main(String[] args) { try { String jndiName = args[0]; InitialContext ctx = new InitialContext(); // acquire the DataSource... this is the only c3p0 specific code // here DataSource ds = (DataSource) ctx.lookup(jndiName); // get hold of a Connection an do stuff, in the usual way Connection con = null; Statement stmt = null; ResultSet rs = null; try { con = ds.getConnection(); stmt = con.createStatement(); rs = stmt.executeQuery("SELECT * FROM foo"); while (rs.next()) System.out.println(rs.getString(1)); } finally { // c3p0 DataSources will properly deal. attemptClose(rs); attemptClose(stmt); attemptClose(con); } } catch (Exception e) { e.printStackTrace(); } } static void attemptClose(ResultSet o) { try { if (o != null) o.close(); } catch (Exception e) { e.printStackTrace(); } } static void attemptClose(Statement o) { try { if (o != null) o.close(); } catch (Exception e) { e.printStackTrace(); } } static void attemptClose(Connection o) { try { if (o != null) o.close(); } catch (Exception e) { e.printStackTrace(); } } private UseJndiDataSource() { }}
