Hello Friends
I m creating a canvas3d by using createuniverse() on Initialization.
After tht on open I m adding a scene to it by using addbranchgraph(GroupScene scene).

Now one object is loaded means a scene is added.When Again I tries to open a new file or object then it is also added.I want to clear the old file from scene.I tried cleanup() fn also.But no Luck.

Is there any other Idea to clear the old scene?
Thanks In Advance.

Regards
Yogesh

Jar File Not working properly

002comp21-Dec-09 21:12

21-Dec-09 21:12

Hello Friends
I m creating a swing based application that loads some 3d Object.
When I run that thru NetViewer then It is working properly .Its opening and when I m loading any file it is coming Fine.
But If I Executes Jar file separately then Its opening but when I tries to open file then It is not opening.

Is it bcoz of some heap size that doesnt get load at run time?Or some other thing?
Any Ideas??

Thanks & Regards
Yogesh

I cannot begin to guess from your description what may be happening. Look at your code and see what it is doing after the Open call. You may need to run it through the debugger to check variable values etc.

Is Google broken today? Try using it and you will be amazed how much good information you will find. Alternatively go to the Java home page where you will find links to everything you need to become an expert java programmer.

Use eclipse for your first projects, write the code by yourself and if you have any problems come back and ask.

Not really the right forum, but at least you're polite about it.

Wink | ;)

It all depends on what you're interested in doing. Java is useful for both desktop apps and web apps; if you're interested in learning more about Java, I'd recommend 'Core Java' for Java SE6, by Horstmann and Cornell. Java's big selling point is that you can build cross-platform apps - that is, you can, for instance, write a desktop app that'll run on Linux, Mac OsX and Windows. Another main platform for web development, and a popular platform for desktop development on Windows, is .Net. (You may have heard of it around here. Wink | ;)

) If you're interested in working with .Net, and perhaps learning C#, pick up a good book on .Net basics and start with it. I really can't recommend a current one; the last one I bought was 'Programming .Net', by Jeff Prosise, but it's way out of date.

Do yourself a favor. Pick a language/platform, buy a good book, and read it cover to cover; not necessarily one of the ones I've mentioned, but a good one. Don't get some 'programming for dummies' type book... unless you consider yourself to be one, of course. Take the time to plow through it. It won't be easy, but nothing worthwhile is, right? If you work at it, it'll show, and people won't torch you for asking questions.

Thanks Lunatic.
My some doubts are clear ,but If I'm a beginner so how can I start with...
C# or Java or .Net

Buy a good book about the subject. That's always the best option when starting something new and it is far more efficient than learning from some tutorials on the web.

JAVA is cool - definitly an point to start from. It has a lot in common with other languages and is base of some of the hot new stuff out there.

U r right but i think start with c sharp..... what's your opinion?
Java or C#.
I want to be a developer... just help me..

TorstenH.21-Dec-09 2:13

no, i don't like C# to be the first language learned. One simple point is the visual editor. It makes it easy to create a User Interface, supports you in building your app - but you do not learn how to write this stuff!

start from a really simple point, do some small projects with simple text output, and buy a good book to read all about the methods you try to use. Those books do not need to be expensive [check this]. But you need to read in them, not just stuff them into your bookshelf.

Java is non-commercial - you can get all the stuff you need for free. And most of the new languages are based on java. Google uses it much - check out the GWT[^] for example. (dont use it yet, it's much to complicated without knowledge!)

You choose, it doesn't really mater.

I will chip in with saying BUY A BOOK. Make that 2 books.

Even though printed material goes out of date, it has one big advantage that you can make notes on it and read, and re-read, to your heart's content.

Learn the theory, understand the differnce between primative data types and objects. Use an easy to learn language - both C# and java are suitable - to practice. But if you really want to learn and do well, understand the basics and learn to walk before you try to run.

You can learn C# from Charles Petzold's excellent introduction[^]. You can use Microsoft's Visual C# 2008 Express Edition[^] for free, and learn the basics for no cost. You can do the same with Java[^] of course. In the end it is up to you to decide which language to focus on, but you may like to compare the number of C# articles to the number for Java on this site, as a guide to which language is more popular.
