JAVA DB Related stuff (Similar to DB02)

Hi ,
Is there any way to view java DB related stuff simliar to DB02, for JAVA standalone engine.
Regards
Uday

Indeed, you can even connect DB02 from any ABAP system to your java database.

List of Conferences to publish Programming (Java) related stuff

Hi,
I have changed class file format such that rt.jar (from jdk 1.6.) size is reduced to around 80%. I have named this new format as TAK.
Note that I have:
* Not use any compression. That implies files are nor jarred or pack200 compressed, neither any other compression techniques have been used)
* Not removed any information from Class files. That implies all the debugging information, dead code etc are still present in TAK files.
* One can convert those files back to original jar file with exactly same data/format. I have not yet written code for it but I will soon support this too.
* One can reduce size ever further by using any compression technique (including jar and pack200). It is because they are not already compressed.
* One can make TAK format executable by writing a new JVM that recognize it
I think this work is publishable. However, I have two questions.
1) Can someone please tell me list of conferences where I could publish such work. I have so far never published programming related stuff and have only published protocols etc.
2) Can someone please tell me some well known Java code that I can use to produce detail results? What I need is some list Java-projects that are well-known to the community and I could show my results on them.
Looking for your reply.

I believe in asking help. For example I prefer to ask people directions instead of seeing maps unless there is no one around to ask or people are rude (do not like to help). It is because I am from a country where everyone asks and help each other. I will find answer of those questions myself, if no one helped me but first I will like to ask. Why you think this is bad?Because you are wasting our time. The time we spend answering questions that can easily be answered using a simple Google search would be spent more wisely answering questions that are harder to answer.
It's rude to waste other peoples time.
Personally I'm less than interested in alternatives like the one you claim to have created as they inevitably lead to fracturing of the platform and thus are detrimental to its adoption.I am not sure what lead you to believe that? I think it will run much faster then existing platforms, however I have to develop a JVM first to prove it.Will it? Smaller doesn't necessarily mean faster. For example I've seen formats that seemed execessively verbose but could be parsed very, very simple and efficient.
Also speed alone is not the important factor. There are problematic factors such as: backward compatibility, existing tools support, necessary investments to include that support in all JVMs (and believe me, there are plenty of JVM implementations out there).
All in all, it can be said that your model would have to give huge advantages to even be worth considering. And I personally consider saving 20% storage on class files not a huge advantages (obviously that looks slightly different on embedded or mobile devices).

A few questions about Canvas and other Image related stuff.

I am just starting to play around with Canvas in the hopes of using it to make a little game (not an applet) in my spare time. I have gotten a ball to bounce around the screen and switch colors when it bounces without too much work. (hooray for me!).
I was wondering:
1) If you always have to repaint the whole area of the canvas, or can you repaint sections of the screen?
2) Can there only be one canvas per frame, or if you can have more, like say, one for each sprite (I tried in my own simplistic way but the second canvas overrode the first when I added it to the frame) or do you have to lay out all the sprites in one canvas every time before you paint?
3) Is Canvas the best platform for rendering my animations and doing collision detection, or are other ways of presenting the images better? By better I mean lower usage of resources, higher speed, accessibility of events that occur. (I have read in the mindprod java glossary "[Canvas] receives all the raw mousing events. Panels, in contrast, see only a few.")
4) In a call to paint which tells it to display some images which are much larger than the frame the canvas is in, is time and effort spent working on those pixels that aren't displayed or does it take about the same amount of resources as for images that fit in the frame since the same amount of picture is actually displayed?
5) Is there any convenient way to layers with canvas besides just controlling the order in which the images are painted. (I will admit I haven't searched for this information yet, because I just thought about it.)
6) Is there any other information you guys would care to bestow on me?
If any of this question is ridiculous, obvious, ignorant or any other negative adjective, then I apologize. I will continue messing around in the meantime.
Thanks
--John

Okay, well I got it to work by drawing them both to the same canvas. duh I guess.
Can you have more than one canvas in a frame? How do you set the size if so.
How do I implement the z-order? I thought of doing it manually by sending the paint method a list of objects to paint and manually managing the order of that list. Would that be an acceptable way to do it?
Should I only be trying to paint to one canvas? What I would like to do is have several canvases with transparent backgrounds so that I can draw different layers in the same frame. That way flying stuff would be painted on a different canvas than stuff on the ground, and then putting it all in a frame would tie the pictures together into a scene. Kind of like how they do distance in animation by having different layers of drawings on clear plastic that they can move at different speeds to give the illusion of depth.
Any advise? Sorry for the douba-post
Thanks

Java blocking related problem

This question is related to other questions in this discussion thread, but about a different aspect.
The program on my QNAP NAS uses Java to bring up the dialog for the selection of files to upload. Each time Java is updated this code has the problem that it doesn't find Java activated. Some other programs seem to do this themselves, but alas the QNAP code does not. A workaround is usually not to use Safari but Firefox. However, today even that didn't do the trick. Only after accessing a site whose code does activate Java itself, is the QNAP code satisfied. As I have no control over QNAP's code (and content with the current version of its system) I would like to know if there is another way to do the Java activation. Once done, I guess it will stay that way until the next Java update. Perhaps something in Terminal? I am not afraid to use that.
By the way: I have the Safari Preferences Security tab checked on "Enable JavaScript" (change and change back doesn't solve the problem, not even after quit and reopen). In the Internet plug-ins tab checkbox "Allow Java" under the button "Manage Website Settings ..." the website of the NAS is listed as having full allowances. More settings relevant to the problem I cannot find. Using the latest MacOSX.
A side note: In "Manage Website Settings ... there are four possibilities, under which "Allow Always". The strange thing here is that in contrast always an alert comes up, asking if I want to block or not. But that is the behaviour I should expect instead from selecting "Ask before Using". Is there an explanation for this? Allthough it is not so much a hindrance, I find it strange behaviour given the label.
Thanks in advance for your contributions on the solution of this problem.

You could try installing the Phony extension and set it to Desktop Firefox. If that allows you to connect to the server then your company's server is doing a bad job of detecting Firefox browsers.

If that does not work then I don't know of anything else we can do to assist as this is a privately controlled server.

Java Lottery - relating arrays to each other

Hello all and thank you for taking the time to read my problem.
I am trying to create a program that asks the user for their name, then how man tickets they would like, then they enter 6 numbers for each ticket.
The maximum amount of 6 number tickets that can be bought is 20.
So for example user1 could get three tickets, user2 could get 10 tickets and user3 could get 7 tickets (20 in total).
My main headache is how to relate the ticket numbers entered with the persons username.
I assume that if user1 gets three tickets these are stored in an array [6] [20] but then when user2 puts their lines on how do I print out at the end who has which tickets?
Also the maximum array size for tickets is [6] [20]...but what if only one user buys 3 tickets and does not use up the remaining 17 tickets, does this affect how I define the array?
Thanks again, all help welcome!

This is sort of what they were talking about, this is an object oriented approach.
There should be no 2D arrays, just arrays of Objects that contain data about themselves or perhaps more Objects.
Try to make your code look more like this.
import java.util.*;
public class Lottery {
 private LinkedList<Person> line = new LinkedList<Person>();
 public Person nextInLine() {
 line.add( new Person() );
 return line.getLast();
 public void showTicketsPurchased() {
 System.out.println( "\nTickets Purchased:");
 for( Person p: line ) {
 p.showTicketsPurchased();
 class Person {
 private LinkedList<Ticket> tickets= new LinkedList<Ticket>();
 void buyTicket( int num1, int num2, int num3, int num4, int num5, int num6 ) {
 try {
 tickets.add( Ticket.sellTicket( num1, num2, num3, num4, num5, num6 ) );
 System.out.println( "Bought Ticket: " + tickets.getLast() );
 } catch (NoSuchElementException nsee) {
 System.out.println( nsee.getMessage() );
 System.out.println( "Could not buy ticket, it's sold out");
 public void showTicketsPurchased() {
 for ( Ticket t: tickets ) {
 System.out.println( t );
 public static void main( String[] args ) {
 Lottery lottery = new Lottery();
 Person servingThisPerson;
 //First person in line
 servingThisPerson = lottery.nextInLine();
 servingThisPerson.buyTicket( 1,2,3,4,5,6 );
 servingThisPerson.buyTicket( 2,3,4,5,6,7 );
 //Second person in line
 servingThisPerson = lottery.nextInLine();
 servingThisPerson.buyTicket( 10, 20, 30, 40, 50, 60 );
 servingThisPerson.buyTicket( 20, 30, 40, 50, 60, 70 );
 lottery.showTicketsPurchased();
import java.util.*;
public class Ticket {
 public static final int MAX_NUM_TICKETS = 20;
 private static int numTicketsSold = 0;
 private int[] numbers;
 private Ticket( int num1, int num2, int num3, int num4, int num5, int num6 ) {
 numbers = new int[]{ num1, num2, num3, num4, num5, num6 };
 numTicketsSold++;
 public static Ticket sellTicket( int num1, int num2, int num3, int num4, int num5, int num6 ) {
 if( numTicketsSold < MAX_NUM_TICKETS ) {
 return new Ticket( num1, num2, num3, num4, num5, num6 );
 } else {
 throw new NoSuchElementException("Tickets sold out");
 * Don't want people to change the tickets numbers after it has been created.
 * @return copy of tickets numbers, not the original array
 public int[] getTicketNumbers() {
 return Arrays.copyOf( numbers, numbers.length );
 public String toString() {
 return Arrays.toString( numbers );

Java Internet related projects ??

I am looking at a project to develop various Internet related applications/applets. However I am having trouble finding beginner type tutorials and such. I have decided to go for a port scanning app mainly because I cannot think of anything else to do in this area of programming. Just wondering if anyone knew of any sites/tutorials for this type of this stuff.
I have just finished reading exactly how the Internet works which has I'm sure will help me.
However I also need advice on what to go for in terms of a simple project and then building on that.
I was thinking of an IP address utility, port scanner but what else is there? Peer to peer perhaps?
Any advice on this area would be very grateful as my searches have come up fruitless on the various search engines although I got some decent code for a port scanner but not where to begin writing one yourself.
I apologise in advance if this is in the wrong area, I am guessing it is the correct one though :)
Paul.

Just select a 'real application' - something that you personally want to do - otherwise projects in the abstract never work.

Hi,
I am not using OID. I am using only JAZN. I copied is_config.xml and wf_config.xml to classes folder where i am running standalone application and also i referred this to the classpath. Kindly do the needful.. I am struggling with this issue for past 3 days.
Another thing is if i am giving the user name as "jcooper" it is throwing the error. If i give "oc4jadmin", then the issue resolved.
kindly tell me what should i do inorder to login as jcooper instead of oc4jadmin
Thanks,
Gomathi

Simple java date related question

Hi Friends,
I have written this custom date class that compares two dates. The user can enter any number of days,and it should calculate the next date,is that possible???
public class Date implements Comparable {
 private int month, day, year;
 public Date(int m, int d, int y) {
 month = m;
 day = d;
 year = y;
 public int compareTo(Object o) {
 Date a = this;
 Date b = (Date) o;
 if (a.year < b.year) return -1;
 if (a.year > b.year) return 1;
 if (a.month < b.month) return -1;
 if (a.month > b.month) return 1;
 if (a.day < b.day) return -1;
 if (a.day > b.day) return 1;
 return 0;
 public String toString() {
 return month + "/" + day + "/" + year;
 public static void main(String[] args) {
 Date d1 = new Date(21, 03, 2007);
 int days = Integer.parseInt(args[0]);
 System.out.println("New date is:"); // Need to print new date
Expected output:
java Date 30
New date is: 04/20/2007If this is not possible with this class,how can we do this, any ideas.
Your help would be appreciated.
Thanks

}I have swapped the day and month around from mm/dd/yyyy to dd/mm/yyyy
but otherwise its still the same basic code

Compiling the java file related to Servlet and Core java files in heirarchy

I am working in Jakarta-Tomcat 4.0.4 with j2sdk1.4.1_01 and i have put all servlet files in package "com.java.servlet"
and other core java files in package "com.java.action" . Also I am imorting java files in package
"com.java.action" to the package "com.java.servlet".
But when I am compiling the servlet files in package "com.java.servlet"
then the servlet files are not compiling because it cannot able to import
java files in package "com.java.action" . I have tried all the options.
If anybody has solution then please respond immediately.

I agree with the previous poster, this sounds like a generic compiling problem. FYI: I do not think that packages that start with "com.java." are special or reserved in any way.
You are making a servlet, not a JSP, right? Since this is merely about compiling, you might want to re-post to "Java Programming".

Need Advice about AVCHD related stuff

I just bought a canon HF-S100 AVCHD camcorder. I will be using it entirely for family and casual stuff. I would like to watch the footage over my HD tv via apple tv. Needless to say I would love to watch the footage at full HD (1980x1080i) or (p, if possible). I would also like to burn DVD's of this HD footage for use via a DVD player...
I have downloaded my first recording using iMovie and it went ok. Only problem is that the movie could be exported in a max resolution of 1280x720. I had to save it as apple tv format and was able to watch it. BUT I want to watch it in FULL HD. 1080 res.
My question is how to do it? What software do I need? Final cut express or pro. I use an imac 24 inch with a 2.4ghz intel core 2 duo. It has 4mb RAM. I intend to purchase a 2TB lacie drive to store the media files. This is going to be my first attempt at video stuff.... In the past I have played with imovie and my old DV camcorder and managed to get decent footage. But the key is to get that crisp HD footage of the family....
thanks for the advice.
Ragz

There is no need for bootcamp, windows, or nero to do what you want. Here's the deal:
You've got two simple options - and more expensive ones.
Option #1 is to go with AVCHD or Blu-ray disks. Either way, you'll want a blu-ray player. You'll also want to purchase Toast 10. Toast will allow you to author AVCHD or Blu-ray disks (AVCHD disks are blu-ray compatible HD disks that are stored on regular DVDs or DVD+DLs.) You can either take completed FCE projects and export them as a simple QuickTime file and let Toast encode them, or you can take your raw footage (stored as .mts files on your camera or memory card) and place the individual files into a Blu-ray project. Toast will then burn without re-encoding. For more complex projects you can mess around with Adobe Encore but I'm guessing you're not going to want to - Toast does an acceptable job.
Option #2 is to pursue digital formats. There are a number of devices that will play digital media, either streamed off a network or from physical attached storage. An example of this is the WDTV from Western Digital. In this case you can take your completed project in FCE and encode it (using QuickTime conversion) into a .mov or .mp4 and then stick it on your network or on a flash drive where the file can then be played by you digital media device. The advantage here being cost - no new blu-ray player, no new software. The downside - it's not quite as simple and quick as inserting a disk into a player, something people are very comfortable with.

Java object related doubt

Hi All,
I have a doubt. Does the code segment of a java class get repeated in all the objects created from that class ? Or the single code segment is used by all objects created from a single class ?
Regards,
Sourav

No, code is associated with a class, and there is a single copy of a class within a process for each class loader that loads it (usually just one).

While using safari, all quicktime related stuff revealed as a question mark

just got my new macbook today. i know i have quicktime, but many webpages i have looked show parts of it with a quicktime icon and a question mark. i am sure there is something i need to reconfigure, but i cannot seem to find out where to start.

This setup should enable you to view/hear pretty much everything:
Assuming you already run OS 10.4.9 or above and have Quicktime 7.2, and are using Safari 2 or 3, download and install (or re-install even if you already had them) the latest versions, suitable for your flavor of Mac, of:
RealPlayer from http://uk.real.com/player/
Flip4Mac WMV Player from http://www.microsoft.com/windows/windowsmedia/player/wmcomponents.mspx (Windows Media Player for the Mac is no longer supported, even by Microsoft)
Perian from http://perian.org/
Adobe FlashPlayer from http://www.adobe.com/shockwave/download/download.cgi?P1ProdVersion=ShockwaveFlash
In Quicktime Preferences, under advanced, UNcheck Enable Flash, and under Mime settings/Miscellananeous only check Quicktime HTML (QHTM).
In Macintosh HD/Library/Quicktime/ delete any files relating to DivX (Perian already has them).
Now repair permissions and restart.
The world should now be your oyster!
You should also have the free VLC Player from http://www.videolan.org/ in your armory, as this plays almost anything that DVD Player might not.
