technical help

I am using jdk 1.1.5,i have written a Timer class in an Applet.
I am passing the parameter from the html file,

I want the arrow to take the path specified as follows

arr_pathx1=170;
arr_pathy1=30;

arr_pathx2=200;
arr_pathy2=100;

I have written the following program for this

The value given from the html file for arrow path is in Pixels,but that
is not taken into account in my program.

So please tell me where i am going wrong
