Bad packet error when link oracle

Question

Need help! Please give me your hand.
Error java.sql.SQLRecoverableException: Io Exception: Bad packet type occurs when I run the application. Here are details:
I worked under Red Hat Enterprise linux 5, Jdk1.6.0_10, Oracle 10.2.0.1. I had downloaded ojdbc6.jar, put it in _/usr/java/jdk1.6.0_10/lib/_, and changed my /etc/profile:
JAVA_HOME=/usr/java/jdk1.6.0_10
PATH=$JAVA_HOME/bin:$PATH
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:*$JAVA_HOME/lib/ojdbc6.jar*
export JAVA_HOME
export PATH
export CLASSPATH
Part of my java application:
import java.awt.*; import java.awt.event.*; import javax.swing.*; import java.sql.*; import oracle.jdbc.driver.*; try{ Class.forName("oracle.jdbc.driver.OracleDriver"); conn=java.sql.DriverManager.getConnection("jdbc:oracle:thin:@localhost.localdomain:1158:orcl","system","zhonghuafy"); /* other code--I had already annotated it */ JOptionPane.showMessageDialog(null,"conn Succeed!","Welcome",JOptionPane.INFORMATION_MESSAGE); } catch(Exception e){ JOptionPane.showMessageDialog(null,"Database Link Error! \n"+e,"ERROR",JOptionPane.ERROR_MESSAGE); }
But when I run it, it seemed that something was wrong:
oracle@localhost ~$ javac testoracle.java
oracle@localhost ~$ java testoracle
errorjava.sql.SQLRecoverableException: Io Exception: Bad packet type
I don't know what's wrong. Please do me a favor!
Thank you!

Thanks for your kindness! It worked! Yeah... I was confused by those ports. I thought the port using in url in jdbc is the one in em. The em address is http://localhost.localdomain:1158/em for orcl instance. Oh my God!
Thank you!
