i didn't fix what i ask first，bu do get understand why the errors come out.
java3d 1.6 was not an oracle release any more，i tried 3 whole days with no progress at 1.5，and what's worse was that there'@ very limited resourse for
 java 3d. so i start thinking to update to 1.6(or even 1.7). at that time i have no idea about jogl at all，so i got these errors.
the mtl issue was fixed just because i turned out to jogl，it's quiet obvious that i can google a lot more than java3d.
