Did you want Geodesic lines? – CaptDragon Mar 14 '12 at 19:18

You mean you will pass two coordinates and color of the line? Intead of "i will pass no of lines and color of the line"? – CaptDragon Mar 14 '12 at 19:52

This demo takes in two coordinates and a color and will create a Geodesic line between them.

DEMO LINK

enter image description here

You can add lines by entering information into the form, OR programmatically like so:

//Taj Mahal to Venice (San Marco)
AddLineProgrammatically(new OpenLayers.LonLat(78.0447, 27.17461), new OpenLayers.LonLat(12.34014, 45.43338), "#006633");
//Roman Coliseum to Mecca
AddLineProgrammatically(new OpenLayers.LonLat(12.49249, 41.89014), new OpenLayers.LonLat(39.8261238221, 21.4225222672), "#feadc8");
// Mecca to Statue of Liberty
AddLineProgrammatically(new OpenLayers.LonLat(39.8261238221, 21.4225222672), new OpenLayers.LonLat(-74.04457, 40.68927), "#3366cc");

This demo is based off of Mr. Wippermann great circle example.

Update per comment:

Simply comment out this line: vectorLayer.addFeatures([pointFeature, pointFeature2]); in the AddLine and AddLineProgrammatically functions if you don't want the markers.
