VRML and JAVA

i�m working with vrml and i wanna make a script in java to send messages with sockets and stuff. to connect vrml and java i need the vrml package, can someone send it to me or tell me where can i dowload it?
thanks

you need to find a 3d library, or use java3d.
the VRML file is describing for example draw a sphere with size that, and that position, with that texture.
a list of such, describes a world.
I think it is possible if you find a 3d library a piece of cake to do it in 180 hours.

when i complie the file contain this, the complier said that there haven't this files or function, how can i use this function? where can download this?
Thank you

when i complie the file contain this, the complier
said that there haven't this files or function, how
can i use this function? where can download this?There are no packages called vrml.* in the jdk. What do you want to do with the files? If you want to visualise the models you could have a look at Java3D, they have some preprogrammed model loaders for VRML if I remember correctly. If you just want to manipulate the markup you can also use the DOM or SAX parsers.

Problems of VRML calling JAVA !!!!

I have created a vrml file which will call a java class. I compiled the class with vrml package found in cosmoplayer 's folder. The class is complied successful, but when i run the vrml file, the cosmoplayer stated that the class can't be found ! But i have put them in the same directory. I tried many examples, all got same result. Hope someone can help me to solve this problem.
Also, i want to ask is that possible to embed the vrml file into an applet panel ?
Thank you for help !!

Hi Ravi,
Thks for helping me to embed vrml into a applet panel, i will try it later. Since i am not familiar with java3d now.
Also, i wonder that why my vrml file can't load the class, the error shown in cosmoplayer browser is can't find the changeColor.class. The program is very simple, just used java program to change color of the vrml objects and i am sure they are in same folder.
Here is my vrml code and java code:
changeColor.wrl:

Whats is difference between Java JRE and Java SDK

Hi,
what is the difference between Java JRE and Java SDK...
i think both of them have the same set of files to be installed...
I am not able to understand where they differ

The JRE (Java runtime Environment) contains just the stuff necessary to run Java and the SDK (System Development Kit) contains the extra stuff necessary (and also helpful) to develop in Java.

What is difference between C# Gzip and Java swing GZIPOutputStream?

Hi All,
I have a Java swing tool where i can compress file inputs and we have C# tool.
I am using GZIPOutputStream to compress the stream .
I found the difference between C# and Java Gzip compression while a compressing a file (temp.gif ) -
After Compression of temp.gif file in C# - compressed file size increased
while in java i found a 2% percentage of compression of data.
Could you please tell me , can i achieve same output in Java as compared to C# using GZIPOutputStream ?
Thank a lot in advance.

Does java provides a better compression than C#?no idea, i don't do c# programming. and, your question is most likely really: "does java default to a higher compression level than c#".
Btw what is faster compression vs. better compression?meaning, does the code spend more time/effort trying to compress the data (slower but better compression) or less time/effort trying to compress the data (faster but worse compression). most compression algorithms allow you to control this tradeoff depending on whether you care more about cpu time or disk/memory space.

What is the diffrence between package javax.sql and java.sql

Is javax designed for J2EE?
And when to use package javax?

Hi,
What is the diffrence between package javax.sql and java.sql?The JDBC 2.0 & above API is comprised of two packages:
1.The java.sql package and
2.The javax.sql package.
java.sql provides features mostly related to client
side database functionalities where as the javax.sql
package, which adds server-side capabilities.
You automatically get both packages when you download the JavaTM 2 Platform, Standard Edition, Version 1.4 (J2SETM) or the JavaTM 2, Platform Enterprise Edition, Version 1.3 (J2EETM).
For further information on this please visit our website at http://java.sun.com/j2se/1.3/docs/guide/jdbc/index.html
Hope this helps.
Good Luck.

What is the diffrence between My Runnable Interface and Java Runnable

Hi folks
all we know that interfaces in java just a decleration for methods and variables.
so my Question is why when i create an interface its name is "Runnable" and i declared a method called "run" inside it.then when i implements this interface with any class don't do the thread operation but when i implement the java.lang.Runnable the thread is going fine.
so what is the diffrence between My Runnable Interface and Java Runnable?
thnx

Hi folks
all we know that interfaces in java just a decleration
for methods and variables.
so my Question is why when i create an interface its
name is "Runnable" and i declared a method called
"run" inside it.then when i implements this interface
with any class don't do the thread operation but when
i implement the java.lang.Runnable the thread is going
fine.
so what is the diffrence between My Runnable Interface
and Java Runnable?
thnxClasses and interfaces are not identified by just their "name", like Runnable. The actual "name" the compiler uses is java.lang.Runnable. So even if you duplicate the Runnable interface in your own package, it's not the same as far as the compiler is concerned, because it's in a different package.
Try importing both java.util.* and java.awt.* (which both have a class or interface named List), and then try to compile List myList = new ArrayList();

Java SE and Java EE

I am a IT graduate and I still need some clarification on the relationship between Java SE and Java EE API. Does EE include SE?
For application development, I know I can use only SE without the EE, but can I use EE alone without SE?
Any good articles addressing my questions?
Thank you very much
R

Java EE in fact extends java SE, its primarily aim is to simplify developing multitier enterprise applications (Java SE provides all the necessary basic libraries etc.)
Because Java EE is an extension of Java SE, you cant use EE without SE - without SE there is no EE.

SSO between Portal and Java WD application

Hi Experts,
I am using CE 7.2 on localhost and I am very new to SAP.
I need to know how can I get SSO between Portal and Java WD. I have a WD application that displays the logged in user using "IUser currentUser = WDClientUser.getCurrentUser().getSAPUser()", as well I can use "IUser user = UMFactory.getAuthenticator().getLoggedInUser()". Both work.
Q1. What is the difference in the 2 above?
Q2. My WD application is set to authenticate user. The WD application is in URL iView. I need SSO between Portal and WD application. Is there a way to get this SSO without SAP Backend (ECC), for now I just need SSO between Portal and Java WD appl.
Everything is in localhost.
Please advice. Thanks.

> need to know how can I get SSO between Portal and Java WD.
Then I suggest you ask your question in the Web Dynpro Java forum instead of the Web Dynpro ABAP one.

J2me and java card, need help to communicate

we are trying to put together a reader to read smartcards using j2me and we figure that it would be easiest if we could develop it to work with java cards rather than standard smart cards, the problem is we get garbage when we communicate to it, the chip sends us crap, any suggestions what might be wrong, any calls we might be missing, has anyone worked with j2me and java cards or smart cards, any help would be appreciated.
einar

.... reader app and the ME behind it .... smells like mobile ....
First of all - if you want to have one mobile application running on this just make sure that whatever is written in ME can use drivers from the reader chip ....
Workin on the PC is something completely different. There was one good example how to develop one host application in Java provided with the JCOP tools long ago ... I don't know if this is now in the new Eclipse tools.
But - there was a small API provided that can give you good hints what to do - and - once you have it on the reader side - you can easily integrate ME methods with this ...

Problem with win2000sp3 and Java web start

I have JRE and Java web start (1.2.0_01, build b01) which come downloading file j2re-1_4_1_01-windows-i586-i.exe from sun.
I have win2000pro running on my PC.
I had updated win2000 to service pack 2 and everything was fine.
Now i decided to update to service pack 3 (in the process I also updated other components) from Microsoft and:
1) Java applets seem to be running fine within i.e.
2) If i try to run an application from java web start my PC freezes and I have to restart it.
3) Staroffice 6.0, which runs on Java, seems to be fine.
I reinstalled both sp3 and jre etc, with no result.
Is this a known problem?
Thanks to all.
Maurizio

I suspect that you have hit a known problem with Swing on Java 1.4.1 with buggy video drivers. Do you have an ATI card? They are the worst offenders. ATI released new drivers for its Radeon line today. They fix the problem.

You need to elaborate "not working" in developer's perspective instead of in user's perspective.

Report Script returns no data and "java.io.FileNotFoundException" error

When attempting to write to a new file (Eg: C:\TEST.txt), Report Script returns no data and "java.io.FileNotFoundException" error occurs.
This error occurs only in Essbase 9.3.1.3 release, however it works fine in release 9.3.1.0.
After running the report the script, it pops up the follwing message:
"java.io.FileNotFoundException: ..\temp\eas17109.tmp (The system cannot find the file specified): C:\TEST.txt"
When checked the TEST.txt, it was empty.

Sorry folks, I just found out the reason. Its because there was no data in the combination what I was extracting.
but is this the right error message for that? It should have atleast create a blank file right?

I continually get a Java error. I've uninstalled and reinstalled firefox and nothing has helped. I've updated flash and Java.

I have used Firefox as my default browser for many years. I've recently started getting a Java error message. It pops up continually. I have updated flash and java. I have uninstalled and re-installed Firefox and nothing has helped. I have had to start using Chrome instead of Firefox which I don't care for but I don't have the java error with Chrome. How do I fix this problem? The error reads as follows:
Java Script Application
Error: syntax error

Your '''JavaScript''' error has nothing to do with the Java plugin . It is likely caused by an added extension (the earlier forum threads [/questions/944619] and [/questions/943088] mention disabling or updating the Social Fixer extension will resolve the problem).
