编译不能通过，求助！

[doctorzw]

下面是我编写的一个bean，主要功能是从连接池中取一个connection
tomcat5服务器
连接池配置绝对没有问题，已经测试通过
我在编译的时候报错
程序如下：

package DBConnectionPool;

import java.sql.*;
import javax.sql.*;
import javax.naming.*;

public class ConPool
{
private DataSource ds=null;

public ConPool()
{
InitialContext ctx=new InitialContext();
ds=(DataSource)ctx.lookup("java:comp/env/jdbc/mssql");
}

public Connection getCon()
{
return ds.getConnection();
}

public void deleteCon(Connection con)
{
con.close();
}
}


错误信息：
--------------------Configuration: <Default>--------------------
D:\Java\Tomcat\jakarta-tomcat-5.0.16\webapps\ROOT\ConPool.java:13: unreported exception javax.naming.NamingException; must be caught or declared to be thrown

D:\Java\Tomcat\jakarta-tomcat-5.0.16\webapps\ROOT\ConPool.java:24: unreported exception java.sql.SQLException; must be caught or declared to be thrown
con.close();
^
4 errors

这是为什么啊

[nanjia]

没有Exception的处理

ConPool throws Excetion{


}

[icy_csdn]

分别catch
javax.naming.NamingException
java.sql.SQLException

[onelifeonelove]

"unreported exception javax.naming.NamingException"
一看就知道没有做扑或异常处理

[trumplet]

这个问题发了几个贴呀？

try {
InitialContext ctx=new InitialContext();
ds=(DataSource)ctx.lookup("java:comp/env/jdbc/mssql");
return ds.getConnection();
con.close();
}
catch (Exception e) {
//异常处理
}
