java.net.BindException: Address Already in use:connect

[BB]

In several of my JSP pages I get this error:-

java.net.BindException: Address Already in use:connect

I cant think why, I close off my database connections
when finished, the code I use to connect is: -

public Connection getConn()
{
try
{
Class.forName("org.gjt.mm.mysql.Driver");
return(DriverManager.getConnection(url, us, pas));
}
catch(Exception e)
{
e.printStackTrace();
return null;
}
}
Thanks
