    Default Help in icosahedron file please help very urgent

    can someone help me get this obj file working
    This is the code called "Phong.java" that I am trying to run with the icosahedron object file.
    I needed to use Phong.java and the teapot input to create a icosahedron
    I have code for an isocahedron as well as a file that is supposed to be used as an object loader. I need help figuring out what is wrong with the code.
    I am not sure what is wrong but I believe it is the input file because it isn't showing me anything when I run it.
    please please please

    here is the code, need help in fixing it
    import javax.vecmath.*;
    import com.sun.j3d.utils.universe.*;

    If this is truly urgent, then why not read the forum FAQ to see how to ask questions here and how to post code so that it's readable including use of code tags? I've deleted the email address as that's not how things are done here. Please let's communicate all on the forum itself.

    Sorry for the sarcasm, but you really should avoid mentioning urgency as your question is no more important than any other question on this site. So please respect all the other folks asking questions here and leave your urgency out of the equation. Also if you format your code well with code tags, folks will be better able to read it, understand it, and help you.

    --- Update ---

    Also, you'll want to show your data file here in the forum and tell us what problems you may be having. Your post mentions nothing that would allow us to understand what's wrong or how we can help you.
