IPaq, Java & 3D Compatibility Question

Note: First off, I'm not entirely sure if this is the right forum to post this in, so I apologise if it's in the wrong place.
Basically, I creating an application that involves creating a 3D landscape via Java 3D and also runs fine on the PC, with the overall aim being to hopefully have it working on a PDA. However, because there's no Java 3D support on any of the JVMs I came across, I'm uncertain as to how to get the whole application working.
I noticed that there's possibly JSR-184, but I'm not entirely sure if it's compatible with PDAs, since I'm somewhat new to Java programming for mobile devices.
What I want to ask is are there are any Java 3D libraries or such that can work on a PDA (more specifically an iPaq rx3715, which uses Windows Mobile 2003, if that helps)?
Any help given is appreciated.

First , i can sure to tell you ,that java 3d can't use in cdc or cldc ,because the library of java 3d is too large , so the jsr-184 or M3G is build for cldc.
But i don't know wether this is compatible with cdc.
And i am from China , a coming graduate , very glad want to make a friends with you .

Just installed Forte as a Simple Server on a Digital UNIX (v4.0d) box (being
a VMSbot it was much easier than I thought). We want to use it to interface
with an existing web client. The Forte part is to provide us a scalable
access path to Oracle DBs on the VMS machine; already running Forte.
I'm having trouble finding media that contains C++ v5.4.-006 for the Unix

drama? How about v5.7 or even v6.1? We will be using extensive C++
interfacing to existing web pages!

OIM Java Compatibility Question

Hi
We have OIM 9.1.0.2 BP07 deployed in Weblogic 10.3.0 in test env. Our java version is JDK 1.6.0_10. All our adapters are compiled in this version. We are using this version of java since 1 year.
Now we are moving to production, and we are not able to get exact java version which we used in test env in internet. My question is if I install java which is certified by weblogic 10.3(i.e 1.6.0_05) then will I face any issues in OIM? is it mandatory to use exact version of java from one env to another?
Thanks

Does not make any difference with sub versions. The version compatibility comes into picture at a higher level like JDK 1.5 or JDK 1.6.
Consider the connector development team, they develop connectors on JDK 1.6 (could be any sub version) and when a customer uses that OOTB connector, they can use any of those sub-versions within JDK 1.6.
Also the fact that if its your custom adapters then you should be aware that what all java functions you are using and I assume it would be the basic ones, so the version difference should not bring in any issues. If its OOTB connector then see the certification matrix as well.

Platform compatibility question(s) from new user!

I'm confused.
I picked up Java a few days ago, with the intention of converting a long-standing JavaScript project that I have to run as an applet. I downloaded and installed the Java2 SDK (1.4) and associated runtime environment, and a simple but good IDE (JCreator 2).... and I'm happily developing applets to my heart's content. Cool language, by the way.
HOWEVER, none of my colleagues (on IE5/5.5 on Win2K/Millenium) can view my resulting efforts. Their browsers complain that they can't find the class. Works on mine, on-line, just not theirs. I've sadly made the assumption that it's because I've installed the 1.4 JRE and they haven't.
I REALLY want to use 1.4 to develop if I can. My JavaScript project that I'm converting is heavily dependant upon regular expression operations, and it would be a pity not to have them available - but platform compatibility is a must; this is a commercial project.
I'm missing something here, and I need to ask some really fundemental questions.
1. I was assuming that most browsers over 4.0 would support "Java2". Just what IS their level of support, by default. I hate new plug-ins, and the Java ones arent trivial!
2. I had thought that any flavour of Java2 (1.2/3/4) would work on the same virtual machine release, and that new features in 1.4 would simply compile to existing bytecode sequences. Am I wrong?
3. If I have to develop for maximum compatibility with earlier browsers, can I do this with 1.4 and some compiler switch, or do I have to download older SDKs?
4. If the worst comes to the worst, is there a class out there that handles regular expression "style" operations that will work on older releases of the language.
Sorry that there's a fair bit there to answer, but since I can't find this info ANYWHERE on the web, I guess I won't be the only newbie facing such issues.
Peter McKean.

just a few points to add to the other answer :
HOWEVER, none of my colleagues (on IE5/5.5 on
Win2K/Millenium) can view my resulting efforts. Their
browsers complain that they can't find the class.
Works on mine, on-line, just not theirs. I've sadly
made the assumption that it's because I've installed
the 1.4 JRE and they haven't.
Yeah the Java support in IE is whack. The m$ JVM never got past java 1.1.4 compatability for various reasons. So unless you want users to install the java 2 pluggins, you have to code applets with the java 1.1 api. You can still do this with a java 2 sdk - you just have to watch the parts of the api you use.
>>
2. I had thought that any flavour of Java2 (1.2/3/4)
would work on the same virtual machine release, and
that new features in 1.4 would simply compile to
existing bytecode sequences. Am I wrong?Yeah you are wrong ;) . When do do:
import java.<package>.<class>
you are telling the compiler where to find the classes you are about to re-use in your code. You are not including them in your final compiled class files. So when the program runs, it looks for the classes in the classpath. If you use classes that don't exist in an older jvm, the program won't run in that jvm. (Same as if a C or C++ program is dynamically linked to dlls (in Win32) or shared objects on unix - they need to be on the system that the program is executed on.)
hope this helps...

Monitor Compatibility Question

I plan on purchasing a Mac Pro with the Radeon X1900 XT card in the near future. I have been shopping around for a good monitor, and the Dell UltraSharp 2407WFP (found here: http://accessories.us.dell.com/sna/productdetail.aspx?c=us&l=en&s=dhs&cs=19&sku= 320-4335) caught my eye. However, at the bottom of the tech specs, it lists only PC under "Compatibility." I know of other people who have used Dell monitors for their Macs, and this monitor does have DVI, so I don't see why it would not be compatible with the Mac Pro. Does anyone know definitively whether or not this monitor would work?

Hello,
You should be just fine. The majority of monitors are listed as compatible with PC's only. The simple reason is that the manufacturers don't care to test them with Macs and have all their resources devoted to supporting what they know.
If they mentioned that it would work with a Mac, then they would be stuck trying to answer your questions on the phone if you needed help. Since they don't use Macs, and don't maintain a staff of Mac trained people, it is easier to just omit official support. That way they can just tell you that they don't support Macs and hang-up the phone.
I've been using PC monitors with my Macs since before Apple even supported PC monitors at all (you used to have to buy monitors with Apple specific cables). I would just use an adapter to convert the PC connector to connect to the Mac video port.
In all my years, I've never found a PC monitor that would not work with my Mac. And, that still holds true today. I've used several low-end monitors with my current machines, and all work fine.
I've even got a bargain basement DVI monitor connected right-now, and it works perfectly.
Basically, if you want official support and a guarantee, then buy a monitor that specifically lists Mac compatibility.
But, if you are willing to accept that their phone support will avoid helping you, then go with any brand you like.
Understand that Dell is primarily interested in selling and supporting Dell computers. They have no interest in fielding calls from Mac users because they are not going to be familiar with OS X. Naturally, they will list PC compatibility because they know Windows very well.
But, you should also understand that the only difference between an Intel-based Mac and an Windows PC, is that the Intel-based Mac can also run OS X. Otherwise, they are just different brands of computers that use pretty much the same hardware.
I hope this helps.

WD Java iView Creation Question/Issue - CE 7.1 EHP 1 Trial

Hi all,
Im posting this question here seeing as that the issue has arrised on an installation of the AS JAVA and EP shipped with CE 7.1 EHP1 Trial.
When attempting to create an iView for a deployed custom WD Java app on the trial Portal I am taken straight to the iView template selection without being given the options for iView creation( ie. create from template, portal component or WD Java app). Is this by design ( WD Java iView creation has changed from previous Portal versions or is limited in Trial installation), is this an issue with the components shipped with the Trial or an issue on my installation only?
Currently my only solution for deploying WD java content is to copy the actual application and paste it as Portal content which then creates a WD Proxy page with a single WD Proxy iView (that of the copy pasted WD app). This is fine for single app scenarios but becomes an issue with multiple apps on one page and drag and relate scenarios.
Kind regards,
Willem.

Java reflection (interesting question)

hi folks,
class A {
void foo() {
Class B overrides method foo() in A
class B extends A {
void foo() {
Now i create a object of class B and assign to A
A aref = new B();
aref.foo() will call method foo()of class B. //polymorphism
Using reflection, is it possible to call method foo() of class A using the handle aref.
thanks
venkat

hi bondvenky,
What abt the answer for my original question. How to
access the base class methods using the handle for
child class object using reflection ?as far as i know, this isn't possible - your next question is probably going to be "why". It certainly seems slightly surprising that you can't do this, but you can access private methods. Unless you consider the latter a weaker way of breaking encapsulation (!?).
what was the sun's purpose behind allowing access to
the private methods of an object using Java
Reflection? good question.. its very useful but on the other hand i can't think of a time i've used it that couldn't be classed as a hack.
Is it not a security threat to java security model?it doesn't break anything - ie its not a security loophole. It links in with your question above though - would it have been possible/useful to not allow it period?
sorry for the vague answers :(

Java/OO Design question. Please help!

Brian,
I'd say your better off trying the
weblogic.developer.interest.ejb newsgroup
or alternatively try the discussion forums in
www.theserverside.com
or
http://forum.java.sun.com/
For what its worth I'd return an empty array rather than an exception as I associate
exceptions with real errors whereas a search that happens to return nothing is a
valid result.
Cheers,

I'm certain this is not the best forum for my question, but I didn't any

I have a design issue/ OO question. Our system has the very common requirement
of searching. We have build a session EJB which actually performs the search
and returns a collection of Value Objects back to the client. My question
is
this: If the search EJB finds no matching records, what is the correct
strategy
for dealing with it?
1) Throw an application exception, such as "NoDataFound", which the client
can
catch and handle appropriately
2) Simply return a null collection. In which case, the client will have
to check
for null, and redirect program appropriately.
3) Simple return type, such as boolean, for the method -- indicating success
or
failure (meaning no records found).
4) Something entirely different. If so, what?
Your thoughts on this subject would be greatly appreciated!
Thanks!

AutoVue for Agile PQM - Java Runtime Environment Question

Greetings,
An end user is attempting to view/open attachments within Agile Product Quality Management (PQM); we use Agile PQM 9.3.1.
When clicking on an attachment file, a pop-up screen opens with a javascript alert, prompting the user with, "Please Install Java Runtime Environment." After clicking "OK", user is redirected to java download website. User downloads and installs the update.
After rebooting the machine, we attempt to access the attachment file again within PQM and receive the same error message, "Please Install Java..."
After installing the first java update, the user is now on the following java version:
Java Plug-in 10.55.2.14
Using JRE version 1.7.0_55-b14 Java HotSpot(TM) Client VM
Do we need to install the second update to be able to view attachments within Agile PQM via AutoVue?
I can't test the java updates myself because there are some legacy Oracle apps that I won't be able to support if I update my java.
Thanks in advance,
William

You might want to post the question to the Agile forum
The popup you see seems to be tied to Agile code itself and not AutoVue
AutoVue will work on Java 7u55
But you are running Agile, so you will need to make sure the rest of the apps are confirmed with 7u55
You also need to review Java update guidelines, by default you will be always prompted to install the latest java update

Java Usage Concept Questions

I have a java Command line running program. Which allow input/edit data of clients and store them into a Flat file. The problem is that i have to make a GUI, ( a thin web based client ) and using only HTML and Javascript.
The next step is the db should be frontended by servlet or JSP that interact with thin client to perform the database retrievals.
Now my concept Questions:
1. Is it possible to communicate to a Java Program using HTML and Javascript? If so, any exampler, pointers?
2. I was thinking of using HTML and Javascript to directly modify the Database. ( Since it is a flat file therefore nothing more than a txt file ) But isn't this side stepping the problem?
3. If i could modify the Flat file using HTML and Javascript only. Why would i need JSP and Servlets? And if i could do it with JSP and Servlets only why would i need the think client ( HTML bit )?
If all of above 3 are correct ( conceptialy ), what is the orginal command line java program for?
The last question is why i think i have the concept wrong. Please i am new to web programming so feel free to point out any error.

Hello,
You a little off on a few things. let me explain what each is used for to give you a better idea what each i used for.
HTML - Used to format data. Is static and can't do any File I/O and such
Javascript - Is usaually used for client side validation and some cool effects.
JSP - Is a scripting language that allows you to execute code on the server to create dynamic content and server side stuff like saving to a DB or a file
Servlets - Kinda like JSP but gives you more control over a few things. Usaually used for form processing and Servlet/Applet communication
for you application i would probably embed HTML/JavaScript for layout and validation into a JSP page for your display pages.. then build JSP pages to handle all you business logic and processing.

"Can you list me some features of the java language"(Interview question )

Hi,
This was a question I got yesterday in an interview, exactly as the interviewer said it.
I listed off it's cross platform feature... what else would you have added?
Question 2. He also looked for #2the differences between java and C++"

It does if you put <sarcasm> tags in/Too easy, and that wasn't the point back then anyway. :)
Look at this forum sometime and see how many people
cram procedural code into a main and still call
themselves "Java programmers". Yepp. I dare to say that I do much better design, yet I don't call myself a programmer, even though I get paid for coding.
Java doesn't enforce
it, either. There's no way to mandate O-O thought.Yes and no. IIRC (it's been a very long time, and I mostly did C, anyway), you can write C++ code without ever creating one class. You can't do that in Java. So It's be a bad OOD, but never a good structural design, as structural design doesn't know classes.

Having a problem with Java Cryptography Extension (JCE)
Author: dnhll23 Jul 6, 2002 2:11 AM
Hi, this is my first attempt at using the JCE. I'm using JCE 1.2.1
and basically all I'm trying to do at this point is encrypt a
FileInputStream object using the DES standard, with the JCE
classes. Here is my code Fragment.
protected FileOutputStream encriptFile(FileInputStream baseFile,
File encFileName) throws IOException
try
// Create the output file for the encrypted document
FileOutputStream encriptedFile = new FileOutputStream
(encFileName);
// Must register the provider that implements the algorithm
Provider sunJce = new com.sun.crypto.provider.SunJCE();
Security.addProvider(sunJce);
char[] pbeKeyData = password.toCharArray();
PBEKeySpec pbeKeySpec = new PBEKeySpec(pbeKeyData);
SecretKeyFactory keyFactory = SecretKeyFactory.getInstance
("DES");
SecretKey pbeKey = keyFactory.generateSecret(pbeKeySpec);
Cipher pbe = Cipher.getInstance("DES"); // Same as above.
pbe.init(Cipher.ENCRYPT_MODE, pbeKey);
CipherOutputStream cout = new CipherOutputStream
(encriptedFile, pbe);
// Use a byte array to write the file output in blocks of 64
bytes.
byte[] buffer = new byte[64];
while (true)
int bytesRead = -1;
bytesRead = baseFile.read(buffer);
if (bytesRead == -1) break;
cout.write(buffer, 0, bytesRead);
cout.flush();
cout.close();
baseFile.close(); // Close the input file.
catch (java.security.NoSuchAlgorithmException nsA)
System.err.println(nsA);
nsA.printStackTrace();
catch (java.lang.ExceptionInInitializerError eIIE)
System.err.println(eIIE);
eIIE.printStackTrace();
catch (Exception e)
System.err.println(e);
e.printStackTrace();
My problem arises with the line "SecretKeyFactory keyFactory =
SecretKeyFactory.getInstance("DES");" This line throws an
ExceptionInInitializerError and the catch block tells me this
java.lang.ExceptionInInitializerError
java.lang.ExceptionInInitializerError: java.lang.SecurityException:
Cannot set up certs for trusted CAs
(The rst of the stackCall here)...
From what I've read in the documentation, I need to have a provider
set up that handles the SecretKeyFactory and encryption algorithms,
but the documentation also says that the SunJCE provider that I set
up near the start of my method should have been able to handle this.
Is there anyone out there with expeience doing this kind of thing
that can help.
Thanks

Have you figured out an answer to this problem yet? I'm having a very similar problem. I'm running an applet that needs to decrypt information that it is retrieving from CORBA and I'm getting the following exception:
java.lang.ExceptionInInitializerError

... 3 more
I'm using JDK 1.4 so, there's no need for my code to have the two Provider setup lines, but otherwise my code looks much the same as yours. The code works fine when run in a test app on the server, but not in the Applet. The file that it's looking to verify (local_policy.jar) does not exist, and I don't want to create one manually, because my users would have to do that then too, which is unacceptable. I am using a trusted applet, so I'm not sure what more I can do to grant the applet the proper permissions. Does anyone have any ideas what we need to do here?
Thanks.
