Java Database Connectivity (JDBC)

Hey,

Okay I am gettting the following error message:
SQLException: 17002 Io exception: Bad packet type
When trying to connect to a oracle db using jdbc and I am running a tomcat server.
I looked all over the inet for a solution - nothing. Some please help me.

Here is the code:

		String url= "jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)"+
		"(HOST=localhost)(PORT=5500))(CONNECT_DATA=(SID=COCKYJOB)(SERVER=DEDICATED)))";
		
		try 
		{
		    DriverManager.registerDriver (new oracle.jdbc.driver.OracleDriver());
		    con = DriverManager.getConnection(url, "scott", "tiger");	
		    //stmt = con.createStatement();	
		} 
		catch(SQLException ex) 
		{
		    System.out.println("SQLException: " + ex.getErrorCode() + " " + ex.getMessage());
		}	

And the error again is:
SQLException: 17002 Io exception: Bad packet type

Thanks for any responses and help in advance.
