Pointer to an unanswered j2ee question

This is just a pointer to a question posted on j2ee that remains unanswered; hopefully someone here can help - I'm attempting to get into j2ee stuff, obviously.

Two books:
(1) "Database Modeling and Design" by Toby Teorey,
(2) "Patterns of Enterprise Application Architecture" by Martin Fowler.
You'll want to know about SQL and normalization. The Teorey book is good for both. Fowler's book will help with writing that data access layer in Java. - MOD

J2EE questions with thick client

I�m trying to move from an existing client-server Swing application (currently talks directly to a database via JDBC) to a 3-tier J2EE model. This is primarily so that I can use HTTP web services on port 80 to bypass firewalls, and to allow for future architectural expansion beyond the current Swing client. I am experienced with Java and Swing, but very new to J2EE, so I'm hoping that there are some obvious points that I am missing.
I am surprised by the lack of 'thick client' examples, tutorials, and documentation that I see with J2EE - almost everything is oriented towards HTML web applications. Here are some questions that I have for using J2EE with a thick client (specifically Swing):
* Where are business logic methods executed? On the client or the server? I get the impression that with J2EE and EJB, all business logic is executed on the server via RPC. Can I choose to have this done in the client instead? If so, how?
* My Swing applications depend heavily on PropertyChangeEvents being fired from the data objects in order for me to update my UI. If the answer to the previous question is that all business logic is executed on the server, then is there a way for my client listeners to receive these change events? If not, how do I know when to update my UI?
* If all business methods are executed on the server, what about accessor methods? Do those need to make a round trip for every call? I've read a little bit about Data Transfer Objects (DTO's) to solve this, but I don't completely understand the concept - if DTO's have no embedded business logic, then how do I know whether a particular getXXX() method has business logic attached to it, and therefore whether to reference the DTO or the server EJB object?
Thanks for answers to these questions. Googling for 'J2EE' and 'thick client' came up with no useful information; I'm hoping to post a HOWTO that will help others after I get this running.

The petstore sample application from blueprints (java.sun.com/blueprints) has an admin module which is a Java Webstart enabled "thick client" that gets business logic processing done on the server. Also the client chapter for the "designing enterprise apps with J2EE" book (also available as html from the same link) gives some tips on designing clients. These may be of help to you

Assign points to quiz slides using Question Pools Manager

Is it possible to assign the points to be reported for a slide when using the Question Pools Manager?
If one slide, for example, has 10 points, and another slide has 5 points, when they are both added to a question pool, do their loose their original number of points and get assigned whatever number of points chosen when a random slide is added to the pool?
I hope someone can clarify. Thanks.

I just checked in Captivate 5 and it looks like the scoring is associated with the Question Pool slide, not the Question slide that gets randomly inserted.
If you're trying to achieve a result where the difficulty of the question matched the number of points awarded for getting it right, you might need to set up a number of question pools. E.g. one pool for easy questions, another for medium difficulty, and a third for really difficult ones. Assign 1 or 2 points as the default for the easy ones, maybe 5 for medium, and 10 points for hard ones.
This is what I do in fact.

J2ee Questions

Hi;
I have same questions concerning J2ee platform :
Q1: I have of the performance problem with EJB entity and would like to use mapping Objects/Tables => so its a good solution or not ? which tool I must to use ?
Q2: how realized a identification of users with diffirents profils (the better solution ?).
Q3: which is your opinion on struts plateform (performance, complexity, ...).
Best regards

Hi;
I'am sorry I have implemented CMP 2.0 EJB under Websphere 5.0 and its very catastrophic for the performance because I manage a big database on DB2.
I have realized of the performance tests with a architecture Mapping objects/Tables (JDO) and its better.
Q2: I will realize a web application (Intranet) and my question : JAAS its a good solution for the indentification or there are another solution ?

Continuously unanswered importing question/consolidating library

I have seen this questions asked multiple times with no answer. Does anyone know how to have Itunes scan library for other music. Also when using the consolidating library feature which "can't be undone" does it convert all your MP3 to proprietary Itune files?
Please help I have been all over this website and the ipod manual!!!!

"when using the consolidating library feature which "can't be undone" does it convert all your MP3 to proprietary Itune files?"
Cnsolidation does not convert songs. When you consolidate, any files in the iTunes Library that are not in the iTunes Music Folder will be copied to the Music Folder and the Library will be updated to point at those new files. Files already in the iTunes Music Folder have no changes made to them.

502 - Web server received an invalid response while acting as a gateway or proxy server
There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server.
This is my web.config for the service and I am guessing there is something wrong with it .It is working just fine on local IIS so I am not sure what exactly is causing the issue.Can someone please have a look and see if they can find something or point me to
a direction.

Unanswered Xgrid question...

Hi everyone,
No responses to my first question. If I am asking a stupid question, just tell me.
I'd like to get a mac pro and connect it to my laptop when I'm home using the xgrid software and a spare ethernet cable, to take advantage of the extra processing speed. Here are my questions:
1: Is this possible without going through a program's source code and parallelizing it line-by-line or something?
Or, for example, can it speed up firefox, etc... instantly?
2: Can I do this under Windows?

I was wondering basically the same thing tonight, as I saw my old Mirrored Drive Doors dual G4 slow to a crawl as I tried to keep several dozen web pages open in Safari and Camino. I checked Apple's and Wikipedia's pages on XGrid, and learned it can't be used to speed up OS X itself, or normal applications (web browsers, etc.) on any of the Macs on the network.
I suspect a similar reason is why jknilinu wanted to try XGrid. With all the little java apps, animations, etc. running in some web pages (across several dozen web pages, it adds up to a lot of them), it would be nice to be able to use an old networked Mac to get more processing power. Add to that the extra slowdown caused by running low on RAM, as all that junk eats it up, causing the Mac to rely on virtual RAM off the hard drive, and things get really slow. Best thing I'd recommend, when you can't add more processors, is the old advice to max out the RAM.

Hello All,
I have searched the entire NI forum to get the answer of the following question. But still I couldnot get the answer.
Which of the following only plots data in evenly distributed intervals along the x-axis? A) Waveform GraphB) Waveform ChartC) XY GraphD) Both A. and B. E) Both B. and C.
The confusion is whether option A or option D. But I guess the answer is option A, since Waveform Chart can plot a single value which is not evenly distributed
Please verify and give your comments.

The answer is obvious once you realize that the person who wrote that question did NOT know that a chart that has a data type of of "Waveform" would use the "t0" value of the waveform to plot that data (provided "ingnore attribute" is NOT set).
So forget about using a waveform data type and then try to answer the question.

J2EE question.. ftp in a session bean

Hi guys,
pretty new to j2ee. I need to make a system that retrieves some files using ftp and manipulate teh files and return to a servlet the link to file (which will live on a webserver).
I read that java.io package should not be used with ejb's. the MDB thats using the ftp api that i created seems to run fine, with no errors. However the files aren't showing up. Am i missing something here?
I give an absolute path to where the files should be downloaded. all i know is that the files don't show up there and that tehre are no exceptions. Could weblogic be storing the files somewhere else?
can ejb's give make directories adn files on the server where they're running?
where does "/" refer to when given in a ejb? is it the root of the file
system or some other location?

grr.. never mind.. its working
sorry!

JMS J2EE question

I am using 6.40, and am running JMS queue tests.
The J2EE engine dies frequently, I have to re-install about once a day.
However, I have consistently increased the size of the Data Volume when I install, and as I do this, the time between crashes increased from about 1 day to every 2 to three days. Now I only have to re-install about every 2 to 3 days.
I guess that means I am filling up the data logs or something. The default is about 400 MG, and I have currently set it to 9000 mg and am getting better response. IN fact I am not sure I will have to reinstall this latest implementation, the 9000 mg install seems to be hanging in there so far.
By the way, the crash behavior is that the broker will not accept send or receive JMS messages, and the J2EE engine will not come up, even if I restart the SAP System from the MMC.
Is there any way to periodically flush the data volume or the logs so it will never crash ?
Is there any way to do this in an automated manner?
Thanks, John

Hi John,
You should enable the "overwrite" mode for the log area. Open the Database Manager, go to Configuration -> Log Settings and choose the Overwrite Mode for the Log Area option.
Hope that helps!

Getting to the point - A long unanswered quest

Alright, I've seen it asked many times, as I've search for it on these forums to make sure I wasn't asking for an already fixed problem.
But everywhere I've looked, the thread died and was left unanswered.
Here's the problem:
I've tried every other fix available, and nothing is in full working order as of yet.
I have Creative SBLi've! 5. with Quadrophonic speakers on Windows XP SP2. All of my speakers are in full working order as of the reply from my contact e-mail to Creative Support, where in that e-mail I described how my back speakers were the only ones that worked and so on.
Now, I'm a musician, and I like to make music, that being what I do, but I need to use AudioHQ to install my SoundFont devices. The problem is, AudioHQ will not work, and I am given the error of "Cannot Initialize Audio Driver. Reinstall Audio Driver."
So, I uninstalled and reinstalled the audio Driver... same error, so I looked on the site and found an upgrade, which, while seeming to not quite match what I was looking for, I tried it anyway... now... AudioHQ works, but I'm back to only having sound out of my back speakers. I uninstalled everything, and reinstalled the original drivers, and now everything works fine again, except I'm again getting the error from AudioHQ.
So, to conclude, if someone could possible find a way to patch or fix their produt so that both AudioHQ and all of my speakers work, that would be grand. I would really like to be able to use this product for the purpose which I bought it for.

I had some issues with drivers for SBLi've 5. Digital and Windows XP quite a while ago. What I did to fix it was to download 377 MB file from Compaq FTP which contained (at that time new) unified drivers for SBLi've and Audigy cards for Windows XP. These were the only drivers that worked for me without any problems.
UPDATE:
Here is the link to that file on Compaq FTP:
ftp://ftp.compaq.com/pub/softpaq/sp2050-2000/SP20920.exe
NOTE:
Before burning the contents of that self-extracting file to the CD, you will have to remove Compaq custom configuration file (CTOEM). If you don't, it will prevent you from installing the drivers and applications on non-Compaq computers and cards.
DISCLAIMER:
These drivers worked for me and my SBLi've 5. Digital under Windows XP. AFAIK, these drivers are the best you can get for that purpose. If you don't get the same satisfactory result please don't blame me or the Compaq.Message Edited by Igor_Levicki on 03-5-2005 02:7 AM

Unanswered quality question

Hi, last year I bought an imac and a wonderful Panasonic PV-GS320 mini DV camcorder to go along with it. I can't tell you how many hours I've spent trying to solve my problems with video quality.
The Problem: Whenever I import DV footage into imovie HD 6.0.4 I lose quality. Now, I know it is theoretically impossible to lose quality on miniDV footage because there are no compressions or conversions on import, but I swear it is happening.
To prove it: I imported a thirty minute video into imovie HD and sent it directly to iDVD without editing a single thing. I then burned directly to a DVD. I played the DVD on a high def, wide screen tv and simultaneously plugged in my camcorder to the TV. I proceeded to flip between the two inputs to compare quality. It is noticeably different. There is a lot more noise and the colors are faded on the DVD, whereas the picture directly from the mini DV tape is brilliant.
The quality loss is apparent the moment I import the DV footage from the camera. How is this possible? Can anyone help me?

What you see in iMovie is a Preview. While you can set the iMovie Preferences to select from 3 quality levels, the Highest level is still not equal to the total video quality that iMovie has imported. To see your DV quality movie from within iMovie, you can connect your iMac to your camcorder and your camcorder to a TV, then select to play the movie through to DV camera. What you see on the TV screen should match the original quality of the DV tape.
Regards.
