Transformation between projections doesn’t work – www.scriptscoop.net

I am trying to make a transformation between two different projections using openlayers but I can not make it work. I am sure that my source projection is EPSG:2100 and I need to transform it to my maps Projection which is the Spherical Mercator. I think that you have to declare your projection first (EPSG:2100). You can use proj4js Library to do that. And something else: EPSG:4326 is not Spherical Mercator it is the code for WGS84. For Sperical Mercator you have to use: EPSG:900913 or EPSG:3857.

One layer is NAD83 and the other is NAD27. When importing the NAD27 csv file, I specified it was NAD27. Then I used. Toolbox->, Data Management ->, Projections and Transformations ->, Project and I projected from the input coordinate system of NAD27 to the output coordinate system of NAD83. I have multiple datasets in my ArcGIS, each having different map projections. All of them are vectors. Some are using Sphere Mercator, others using WGS84. I cannot perform the reprojection function in ArcGIS as I do not have the formula for geographic transformation. I am stuck and cannot proceed to make a map due to this issue. Source.
