That is not sufficient, for example the tilesOrigin will create problems. You can try setting it to -180.0,-90.0, but there could be other problems as well.
I repeat my suggestion to look at the source of the URL I gave you. My experience is that it's much easier to tweak a working copy than to fix one with broken tile alignment.

Hello Arne, Thanks for the fast answer...
I changed the EPSG , as you recommended:
var wms = new OpenLayers.Layer.WMS(
"Univ",
"http://localhost:8080/geoserver/wms?",
{
layers: 'tiger-ny',
styles: '',
srs: 'EPSG:900913',
format: 'image/png',
tiled: 'true',
tilesOrigin : "143.60260815000004,-43.851764249999995",
transparent: true
},
{
'opacity': 0.75, 'isBaseLayer': false, 'wrapDateLine': true
}
);
But it stills come away from the target, as you can see in attach.
Do I need to reproject it? If yes, what is the best software for that?
