Java y oracle

[polaco83]

esta es mi conexion:

void conexion(String sqls)
{
Statement sql;
String DBURL = "jdbc:oracle:thin:@<ip>:1521:base";
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
}catch(ClassNotFoundException e) {JOptionPane.showMessageDialog(null,"No se pudo cargar el controlador");}
try{
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
con=DriverManager.getConnection DBURL,"usrwebtrack","usrwebtrack");
sql=con.createStatement();
rs=sql.executeQuery(sqls);
while( rs.next()){
cmb_excepcion.add(rs.getString("par_codint").trim( )+" - "+rs.getString("par_descripcion").trim());
}
rs.close();
}catch(SQLException evxc){JOptionPane.showMessageDialog (null,"Error al Conectar con la Base");}

}



al compilar no aparece ningun error, pero al tratar de ejecutarlo, con el: appletviewer app.html, aparece el siguiente error:
