Never mind. I finally figure out what was wrong!

Turns out that the shader was not being compiled. I
had to use this code to check if the shader had compiled
successfully:

        {
                int[] out={3};
               
                gl.glCompileShader(vShader);
                gl.glGetShaderiv(vShader, GL3.GL_COMPILE_STATUS, out, 0);//the zero is the array offset, where the function should start storing the information
                Log.printDebugMsg("out="+out[0]);
                int result=out[0];
                if(result==GL3.GL_TRUE)
                        Log.printDebugMsg("Everything is good");
                else if(result==GL3.GL_FALSE)
                        throw new Error("Shader not compiled correctly");
                else
                        throw new Error("Should not be here");
               
        }


After it returned false then I check the shading code
and changed the version to #version 150 and that did the trick.
I guess my computer does not support version 430.
