Thanks a lot, it works with appletviewer indeed. However,it is also supposed to work two other ways, isn't it?
- with the help of a browser
- using java HelloUniverse
There is also a general file java3d\index.html to launch all demo applications, which does not work. I think that either I have missed something in the installation process, or there is a bug I am not aware of. I also suspect that since this 3D software has been developed by the Sun Microsystems already three years ago, there should be a ready answer to these simple questions somewhere in a support website. Do you know if this support (on- or offline) exists?
Sincerely,

I have installed Java 3D API software and wanted to start some
test programs, but all of them failed. The error messages are nearly identical, indicating NoClassDefFoundError. For example, the following error appears if I try to start HelloUniverse:

"
C:\jdk1.2\demo\java3d\HelloUniverse>java HelloUniverse
Exception in thread "main" java.lang.NoClassDefFoundError:
javax/media/j3d
GraphObject
"
Any idea how this could be corrected? Assume that JDK1.2 is installed without a fault.
Thanks in advance,

I would like to draw a set of simple objects such as spheres or cubes in 3D. Is there an available java library for this, or I need to write down all these classes myself?
Thanks,

JQ+ has a website
http://enthuware.com/jqplus/
The simulator costs something like $20. at the beginning I was a bit confused to see many typos (like "seperate" everywhere), but the codes and comments are very helpful and professional.
I also heard a lot about JCertify and other codes, but never tried them, I know that they cost above $50.
If you train 1 or 2 weeks with such a simulator, taking, say, 1 exam a day and analizing and fixing ALL error answers in detail and if after this time you have above 75% on NEW mock exams (there are 8 in JQ+, smth. like 500 questions), your chances on a real exam will be substantial. It was critical for me, but if you have 10 years of C++ experience, maybe you can do without it. It depends.
One trap is RHE itself as well as most of the mock exams. You read RHE and answer all the questions in the mock tests in it and also train in open mock tests. The RHE questions are too simple compared to half of the real exam questions. Beside, once you take a test, there is no sense to take it the second time- you loose the feeling of danger. A solution which I found (at least, in my case), beside trying what is available in popular websites, is to buy one or two commercial simulators, which have some hundred test questions and tens of different exam variants. The level of comlexity is comparable or slightly(which is important) higher than that of the real test. Apart from getting used to real timing, it is a great education as well!
I have just passed the SCJP2 with 79% score. I consider it decent, having absolutely no OOP experience until 4 weeks ago. Yeah, I did some years of Fortran, but it sounds funny here, isn't it? RHE book is very good but positively insufficient to prepare for the exam. I attribute half of my score to it and another half- to all mock exams I took during last two weeks. Particularly, I used a commercial JQ+ simulator, which surely justified its price.
The exam itself was easier than most of the mocks I took the first time.
I enjoyed this forum and learned a lot from it. Good bye, guys!
I wonder if 2 "privacy statement" questions mentioned in suned website count at Java2 cert exam? If yes, what are they all about? If not, why they are included in the list?
Any idea?
Andrey
"Q. Will there be the same number of questions?
A. Yes. There will still be 61 questions, two of which are part of our privacy statement."
Could anybody tell me if there is a website informing about all conditions of SCPT2? I could not, for instance, find exact timing and passing score.
Please hlp
Andrey
I wonder if there is a mock exam covering events/awt/threads and collections approximately at the complexity level of real Certification Exam? As I understand, these topics are critical, but the exams what I checked seemed to me either too complicated or too simple on these issues.
Thanks in advance!
