Simple opinion question from a newbie about IDE's

I have been looking around for the best architecture for a n-tier client server app. I have been using the jsp/servlet architecture for a while, and have recently found out about web-start . There seems to me to be a great advantage to be able to maintain state on the client, as opposed to having multiple roundtrips to the server.
My questions are:
1) What is the easiest (i.e., any open source tools/ide's?) way to build a full featured gui for a desktop application that will connect to servlets or web services and can be deployed via web-start? I would prefer a gui builder with many available widgets - are there any out there?
2) what is the difference between JNLP and web-start?
3) How do you bind gui controls (swing/swt/whatever) to the data? I.E., I used to work in Borland c++ builder and there were data-aware controls. Does java have any similar controls that can be bound to a datasources?

1. I'm sure there are a few out there, but the ones I've tried created crap code, so I usually roll my own.
2. Java WebStart is the name of the JNLP implementation that comes with Sun's JRE (but the two are often used as synonyms). There are other JNLP projects, but most of them seem to be dead.
3. I'll leave this to someone else.

Question from Mac newbie about system and startup programs

I recently switched from an old Win 98 computer and LOVE this macbook! Could someone please explain a couple of things to me?
Two windows now suddenly appear when I restart my computer - one is a window with all the files and folders stuff from when I installed my Canon MP500 printer last week. Why is this box opening at startup, and can I get it to stop?
The other suddenly opening at restart is a simple Finder window showing my hard drive and network. (I am not connected to a network). What's the source of these things starting up? How can I fiddle with this setting? These things are not listed when I go to System Preferences-Accounts-Login items.
On Windows you can hit CtrlAltDelete and see all the running programs, even background programs. How do I do it on the Mac?
Thanks,
-Alden

Charles I'll start from your last question. You'll find "Activity Monitor" in the Utilities folder (inside Applications folder) that's the equivalent to the Task Manager in Windows. you can leave it in the dock to have it handy.
About the Canon printer window showing when you start; see if it has an open icon on the dock when it's open. Click and maintain clicked on that icon (if there is one) and uncheck "Open at Login".
Finder Window usually opens at login if it was open when you logged out
Oh, and Welcome to the forums!

Question from a Newbie wireless user

Please excuse the naivete of this question. I'm completely ignorant on everything pertaining to wireless internet. My old Powerbook 400mHz G4 Titanium has never had wireless of any kind until this week when I bought a PCMCIA wireless adapter. Never used wireless, don't know anything about it.
I started following the instructions on the PCM adapter this morning to get it all set up. I plan to toggle back and forth between wired internet at home and the wireless adapter when I'm out on the road.
I was surprised when I saw the window where I enter my settings that there were no less than ten different internet services flying around the room in my house! I guess I have a lot of wireless neighbors and I could easily access their bandwidth.
I imagine the same would go when I'm in town sitting in the library. They welcome you to use their internet access, but it's in a busy end of town and I'm sure I'll see numerous services available there too.
So I'm clueless on this topic. Again, I've never used wireless internet before - but I've read about these guys who've been arrested in front of coffee houses for stealing bandwidth at WiFi hotspots when they weren't paying customers.
What's the deal with sitting in your living room and using your neighbor's internet access? I know it's not ethical and we should all get our own, but what are legalities? And say I hopped on to someone's internet access +quite accidentally+...how does one get caught if you do it quietly? And have people actually gotten into trouble beyond these two guys that made national news?
I guess my main question is exactly how careful do I need to be to set the correct access service when there are ten immediately available in a public place? Can I just click on whatever signal is strongest and log on without fear of being caught?
I hope somebody knowledgeable can set me straight on this.
Thanks.
-JOHN
ps. Here's the news item on these guys stealing wireless internet access:

You may find this technical article I've written helps you:

Four questions from a newbie!

Hey, I have a few questions to ask actually about my macbook pro...
When I bought my MBP, I ordered one with 120 GB, but when I got it and checked the hard drive, it said it has 111.5 in total. Am I missing something or did they just happen to forget to put 9.5 GB in my hard drive? I don't know if this is a normal issue or otherwise. There also seems to be a flux in hard drive space even though I haven't installed anything (even automatic updates).
Also, I'm moving away for college so I'll be an ocean away from my house. In case I wanted to repair my MBP, should I bring the box it was delivered in? I really don't know the process, but that box is quite unwieldy, and space is an issue on the plane...so I need to know if its necessary to take that box with me for a repair service.
I also have this buzzing noise emitting from the left speaker whenever I plug in the power adapter. I know this is a prevalent problem (from what I've read) in older MBPs, and since I just got mines this week, I don't know if it's normal or what. Also is heating an issue? Whenever I leave the laptop on my lap, the area in which the battery is placed (as well as the entire back and speaker area) heats up. I don't know if it's a common thing or not...
I know I asked a lot of questions but thanks in advance!

I'll try to answer as best as I can....
1. This is normal, the "missing" space is taken up by the operating system and various system components... even when you format the drive, there will be some missing, it is completely normal.
2. You do not need to bring the box, apple will send you a shipping box if you need to send it in, or you can bring it to the apple store closest to you. Do however, bring your system disks that came with the computer, as those are always good to have.
3. This may be the whine that is common, there are a couple variants of the whine, read through here and see which one is yours and then the repair option would vary from that. You could always return your MBP for a new one though since you are within the 14 days... The MBPs do run how, you might want to invest in one of the products such as iLap that help with that, however, if you can handle it, then it should be fine. This is common with these units.
4. AppleCare is auto enrolled, they used to send you a little license agreement and CD with techtools on it, but I don't think they do that anymore since the box that you buy in the store has a non-intel CD inside.. you are enrolled if it says you are enrolled, and thats all that really matters, after all, you can always call apple for questions.. If you do exchange your MBP though, be sure to have them transfer the apple care to the new serial number as well...
Hope this helps!

I Have a question from a Customer about ONLINE OPTION

Hi all,
I have the below question from one of my customers, and non being a DB expert I am not able to answer or even where to find a documentation supporting the answer.
"We need to know how the "Online Option" to reorg indexes or tables is safe to be used, this way:
- Alter table ... Move .. online;
- Alter table ... Rebuild .. online;
to understand if the technique can be used to maintain the DB without stopping service to end users.
The DB is in 11gR2. I do not want notes or PDF's but just answers on:
- It's Safe ? yes/No or Yes with some tricks, Best practices (which?)
- Any known issues or bugs or patches to be applied (or Service Packs)"
I was planning to setup a Bug Review with my ACS Service Engineers but they would like a quick preliminary answer to the fist question before starting the full Bug Review.
In my understanding, the Online option is to reorg indexes and not tables... am I right?
Which can be a documentation page or community discussion or any additional link you can share ?
Or may be you just have a full answer :)
Thank you
Kind regards
Chiara
Edited by: Chiara Scarafiotti on Jun 7, 2013 2:35 AM

Rebuilding an index online will lock the base table at the start and end of the rebuild, this can cause issues if there are active transactions see http://richardfoote.wordpress.com/2008/02/11/index-create-and-rebuild-locking-improvements-in-11g-ch-ch-ch-changes/
alter table move online will make any associated indexes unusable and these will need to be rebuilt after the table is moved.
Two other options:-
for indexes a coalesce is generally faster and requires less space.
For everything dbms_redefinition has more options and is less intrusive at the expense of being more complex.
Also probably the biggest risk is you move tables rebuild indexes charge your customer for all this work and it fails to improve anything (or actually makes things worse)

Miscellaneous - Questions from a Newbie

I just got my iPhone this week and some questions popped up. I know that some of them might fit better in other categories than "basics"...
1. Sync with Outlook - I was under the impression that the iPhone syncs up with Outlook but:
a) How can you mark an Outlook Appointment as "privat" so not everyone in your company who has access to you calender can read it?
b) Why are no documents synced, which are in a Calender Appointment save in Notes? (The Text in Notes will sync, but no PDFs for example...)
c) When I reply to an E-Mail, the info that an when I replyed is not saved in Outlook
d) in Outlook I can mark e-mails with priorities... this is not shown on the iPhone
e) can the Auto-reply or Out-of-the-Office message set or changed from the iPhone?
2. Mail
a) I have differnt E-Mail accounts and would like to use different signitures for each account... the is an App, but thats too complicated. Is there a way to have an automated signature for each acount (this should be a basic feature!!!)
b) Can I save e-mail attachments in specific folders? (eg a word doc)
3. Media
a) How can i created different Folders in the photoalbum, so I can sort them and don't have to scroll for ages...
b) Can I get access to the Folders on the iPhone, so I can copy (for example Music) for differnt sources to the iPhone?
c) Is there another Sync programm than iTunes?
d) Can I delete Apps which I don't use (eg. Weather, Stockmarket...), but which are allready installed when i bought it
4. Sounds and Alerts
a) Can i create my own ringtones (eg an mp3)?
b) Can I add other alert sounds (for E-mails for example)
c) How can I change sounds for different Events (New Mail, Alert...)?

b) Can I use the iPhone as a modem for my laptop? how?
c) If stolen, can I remotely delete it or search it via GPS?
6. Battery
a) is it normal that when you use push mail and make a couple of calls a day the battery only last for max. 20 hours?
Thats the first lot of question from week one... Thanks in advance for replys and the awaiting answers
Axl

I can answer some of them:
Is there a way to have an automated signature for each acount (this should be a basic feature!!!)
No
b) Can I save e-mail attachments in specific folders? (eg a word doc)
No. You can't save attachments - just view them
b) Can I get access to the Folders on the iPhone, so I can copy (for example Music) for differnt sources to the iPhone?
No. The iPhone cannot be directly accessed like a hard disk. There are third-party apps that allow this to a certain degree, but you can't add Media to the iPhone via this method.
c) Is there another Sync programm than iTunes?
Not really. There's some that may do some features, but not a complete replacement for it. What's wrong with iTunes?
d) Can I delete Apps which I don't use (eg. Weather, Stockmarket...),
No. But you can move them to a different Home screen.
a) How can i created different Folders in the photoalbum, so I can sort them and don't have to scroll for ages...
http://www.question-defense.com/2009/08/15/how-to-create-photo-albums-on-your-ip hone-on-a-windows-xp-computer/
a) Can i create my own ringtones (eg an mp3)?
Yes. Google "create iPhone ringtone" for a variety of options
a) Can I sync the iPhone over bluetooth?
No.
b) Can I use the iPhone as a modem for my laptop? how?
Yes, although it depends where you are. See:

c) If stolen, can I remotely delete it or search it via GPS?
Yes. See MobileMe's "Find My iPhone" feature:
http://www.apple.com/mobileme/features/iphone.html
a) is it normal that when you use push mail and make a couple of calls a day the battery only last for max. 20 hours?
Quite possibly. Battery life seems to be reduced in the latest firmware and lots of people are awaiting a fix from Apple.

Simple question from jsp newbie

Hi friends,
I am learning jsp now. Reading documents and implementing simple applications. But i want to ask a question that is opposite to my logic.
Now, i am a textfield control on jsp as textField1. I have created this control from Palette. in java code i am writing "textbox1." but there is no action, no intellisense while pressing ctrl + space.
How the control is accessing from java code? Maybe my logic with visual studio .net. but i want to learn jsp logic.
Thanks.

Books/IDE question from a newbie

I'm an experienced developer of Microsoft technologies, but I'm at the beginning-of-the-road with regard to Java. I just purchased "Core JAVA 2 Volume 1-Fundamentals" and "Designing Enterprise Applications with the J2EE Platform, Second Edition".
Can anyone suggest other "must have" books for developers who are new to Java? Also, beside the ever popular and robust "visual notepad", what is the best IDE for Java development?
Thanks for your help!

Hi!
Two good books are:
Java Cookbook, O'Reilly
Java In A Nutshell, O'Reilly
I used them daily as a reference.
A good and free IDE I am using is called JCreator. It's pretty simple but is enough for me. Some other good IDE's is:
Forte
JBuilder
Best of luck!

IWeb questions from a newbie

Hi everyone...
I am looking into making my own simple website and am trying to decide whether to make one from scratch or use iWeb and a .mac account. Any advice for the following questions would be appreciated!
1. I see a lot of iWeb sites that have the ugly "web.mac.com" preceeding the site name. Other iWeb sites don't have this prefix so obviously there is a way to do without it. How do you eliminate that prefix?
2. My site would only hold a resume and half a dozen short vid clips. But I've noticed on other iWeb sites that the video loads EXTREMELY slow (on a high speed cable line!). Is this a flaw with iWeb (is there a recommended compression rate for vids to play on iWeb)?
3. When I bought my G5 it came with Garage Band, iMovie, iPhoto, etc. (everything EXCEPT iWeb). I noticed that in order to purchase iWeb, you have to buy all these apps again which seems like a waste! Is there a way to buy or download JUST iWeb?
4. I've done lots of research on iWeb and on Amazon.com virtually everyone prefers iWeb '06 over iWeb '08. Isn't the newer version supposed to be an improvement? Does anyone know what the fuss is about...and is it a better idea to purchase the older version ('06)?
Thanks for any help you might have!

1. It's called personal domain. You have to buy a domain at a domain regitsrar like GoDaddy. Example: yourdomain.com
Or Publish to a folder and upload to a server other than .mac
2. It's not an iWeb issue. It's a hosting issue, thus an issue about .Mac. Publishing to a hosting other than .Mac speeds up things.
3. iWeb first appeared with iWeb '06 in iLife '06 package. You maybe have iLife '05 or deleted it by accident (or not by accident)
And no it isn't a waste as the applications are new versions, thus improved. New features included and so on. And no there's no way to legally download/buy only iWeb.
4. I like iWeb '08 a lot more than iWeb '06.
There are compatibility issues with the worst browser of the world, also commonly called InternetExplorer. But it's not an iWeb issue... It's an IE issue.
Regards,
Cédric

A few questions from a newbie!

Hello!
So, I am VERY new to using Mac productions and I just got my Macbook recently.
I have a few questions that may seem to have a very simple and obvious answer but like I said, this is all new to me...
1. Do I have to install a anti-virus/spam program? If so, which one?
2. Time Machine- this is the program to back up files right? when I try to set it up it doesn't give me any options for a back up disk.
Anything else that I should defiantly know please let me know!
Thanks so much!
Alanna.

Not unless you want to. I have had Macs for 2 years and never had a problem. This is a good one if you decide to install one. ClamXav
2. Time Machine- this is the program to back up files right? when I try to set it up it doesn't give me any options for a back up disk.
You need an external hard drive attached to use with Time Machine. This explains it.

This is info that will help you get the best life from your battery.
It is OK to leave your battery hooked to the charger most of the time. The only time I unhook mine from the charger is when I calibrate or for a few minutes to use in another room. Have you calibrated your battery yet? You should calibrate every two months or so to keep the battery fully functioning. If you use your MacBook infrequently, it’s best to re-calibrate the battery at least once a month.
It is best not to use your battery unless you need to. Some people have hurt their batteries by charging then discharging every time they use the MacBook. This will age a battery very fast and cause you to buy a battery sooner than you should have too. Don't discharge the battery just because you used it. Li-Ion batteries prefer small charges over big ones. Use it and then plug it in as soon as you can. The only time my Battery is ever fully discharged is when I'm doing a calibration.

Keyword questions from the newbie

Would anyone mind helping me figure out if there are conventions for entering Keywords into pdf Metadata? I have been having a conversation on another forum about Keywords for images and there is some question in my mind as to whether I should use quotes around a term such as "plate of shrimp" or if I should just use Plate Shrimp. One poster said they were avoiding using spaces for some reason and that they use PlateShrimp.
Anyway, am I correct in assuming that all this goes back to how google searches Metadata in pdf's and/or images??
Does anyone know where to find some of the conventions or standards associated with this? For instance, doesn't google search the /content/ of the pdf and if so wouldn't a keyword have to be /different/ from one in the METADATA? Or ostensibly google would rank a keyword /higher/ and the other Maetadata in a pdf would be associated with Contact and/or Copyright info?
I am a total newbie with this so I am trying to winnow things down here with a little help if possible. I've been able to find info on IPTC Metadata but my assumption is that this only relates to images.
Thanks.

1. Is there a "recent documents" on a Mac?
Only under the programs you use like Pages.
2. When I have a disc in the notebook and I pick up the computer is it normal for the disc to grind inside the unit? It sounds like a garbage disposal.
This happens because you move the macbook and the disk is spinning. If you don't tilt it this usually is OK but tilting causes the noises your hearing and it is damaging the disk.
3. What is the American flag in the bar at the top right of the desktop? It wasn't there yesterday.
It is the input menu for special characters and keyboard viewer if both are turned on under system preferences. Look under International Input Menu.
4. Can I run Final Cut Express on the Macbook without problems, or should I have gotten a Pro?
Yes I use it and it works fine. Max out your RAM for the best results.

Questions from a rookie about event structures

Hello,
I am currently scheduled for Labview classes next month,
so I want to apologize in advance for "dumb questions". I have created
a program that is starting
to be a CPU resource hog. The majority of my program is inside a while
loop so that the program will "react" to changes in controls, etc. I am
assuming that
if I incorporate "event structures" in my program that my program will
not be a resource hog. Is the use of event structures the correct
way to go? If using
event structures is the correct way to go, what is the best way to
learn how to incorporate "event structures"? I am assuming that
the examples in Labview will show me how. Are there any good reading
materials about event structures?
Regards,
Kaspar

To fix the CPU resource issue, you need to place a small wait statement in your loop. It will solve two problems:
Slow down the loop (you don't need to check for UI changes more that 10x/second)
It will allow other, parallel tasks a chance to run after each iteration. Without a wait, it will hog the CPU for 55ms before releasing control.
If your loop currently spins one million times a second and you would place a 1ms wait, the CPU would go from 100% to 0.1%!
The event structure is a fantastic tool to solve most UI issues and it makes the diagram automatically simpler, more self-documenting and easier to read. Have a look at some of the examples that ship with LabVIEW.
The event structure is easy to learn, so dive right in. Read the online help for some important considerations. As a rule of thumb you should stick to a single event structure per diagram.

Top 3 questions from a newbie

Hi folks, I have performed a basic search and didn't turn up an answer to these so am looking for some guidance please.
I love my Nokia Lumia 800 and think Nokia Here (nee Maps) and especially Nokia Drive (which I use every week) are awesome but here are my three questions/requests and hope Nokia is also monitoring these posts.
1. Could we please be told if Nokia are working on a way to use your address book contacts to set a destination. I used to have this on Windows Mobile 6.5 and most other smartphone OS's have this. I find it hard to believe that Nokia with such innovation and being a recognised leader in mapping that this isn't available.
2. Can someone tell me how to enter a junction of two roads into Nokia Drive and Nokia Here as every combination I have tried doesn't seem to work e.g. High street and Bond street
3. Could we please be told if Nokia are working on a way to use a separate volume / audio session to avoid impacting any playing music when using Nokia drive or maps, this will allow a driver to lower the volume of the GPS app and leave the music at the correct level without impacting it. I used to have this on the Smartphone TomTom software on Windows mobile 6.5 also
Thanks and apologies if these questions have already been dealt with elsewhere

About n°1: the method I was told to use does not work:
To navigate to contact: from the contact list, open a contact, click on "map home address", this starts Here maps, then click the "directions" button, then enter, then choose the car, this starts Here Drive.
The problem with this method is that at the "direction" step, the destination is not is exact address you're heading to, it's just the town.
So I still haven't found a way to do that. It seems pretty simple for Nokia to repair the missing link between here maps and Here Drive: just set the full address in the "destination" text field mentioned above.

Pages DTP questions from a newbie

Hello. I'm new to Pages 'page layout' but have used other low-end DTP products on Windows (Serif's PagePlus was pretty good). I'm under pressure to complete a document but can't seem to figure some things out. I hope someone can help with these questions.
1. Is it possible to 'autofit' text into a text box. With a fixed document I find it difficult to fine tune the last page so that the text and images fit OK. In other applications I think the software was able to fine tune the font size so as to include all the text of to avoid clipping a word or two.
2. Can I permanently 'lock' design and text elements together, so that they will always move, and maybe even change size together. At least I'm thinking of e.g. a photo with its caption. I know I can select both and for that time move them together, but I can't see a way to make that relationship permanent. Can I permanently lock them together? Can I 'lock' a complete page?
3. Is it possible to use a 'reference' to an image held elsewhere on my hard disk? Ideally I'd like to be able to have my Pages document reflect changes (e.g. colour adjustments) to the master source image. For example in Serif PagePlus it would only 'embed' images below a certain size, and bigger images were just 'linked' to in the master DTP document.
4. Is there any Apple or third-party application that can convert a Pages DTP document into a web page?
Thanks.

1 and 3 I fully understand, but I'm not clear about your explanation in 2. For example if I place a photo in a layout and then add a caption beneath it, are you saying that there is some way I can 'lock' them so that they behave as a unit?
Probably a limitation on my side, but I don't seem to understand what you want to do :
1) are you asking if a frame with a photograph and a frame with a caption for the photograph can be grouped, and that the grouped frames can be automatically moved if more material is added above the group in continuous single column mode (wordprocessing mode), or
2) are you asking if the frame with a photograph and the frame with the caption for the photograph can be grouped and can be automatically moved if more material is added above the group in discontinuous multiple column mode (layout mode)?
The problem lies in the way the problem is posed, so to speak. While you would want (1) because in continuous single column mode there is no concept of fixed co-ordinates for frames, you would not want (2) precisely because in discontinous multiple column mode there are fixed co-ordinates for frames.
A story that starts in a frame on page 3 might skip page 4 and continue in a frame on page 5. If the positions of the frames you defined did not preserve their fixed positions, the concept of flowing copy from one frame/column to another frame/column would not work.
There appear to be problems in Word for Macintosh 2008. If I understand the MacWorld review roughly right, and I may not have done so, then the behaviour is still that of wordprocessor when the application is used in layout mode, and that would have to be a bug (not that Pages does not have its fair share of those, of course).
"The first time I ran into any limitations in Word was when I started to add floating objects—such as pictures and callout text around which text flows. For starters, its image-editing tools aren’t very good. More significantly, when I changed a column of text, the floating objects in it refused to stay in place. Instead they moved around as if tied to the text they were originally placed next to, destroying my layout. If I selected all the text in a document and deleted it or replaced it with text from the Clipboard, floating objects within the original text disappeared, too. In other words, if you make any major changes to a document after inserting floating objects, you’ll probably need to completely re-create your layout."

Question from SAN Newbie

Traditionally we've always used NAS based storage for our server load balancing solutions.
With SAN, is it possible to set up shared storage that can be accessed by multiple servers simultaneously for the purposes of load balancing ? (web/email) I know you can configure individual storage volumes for use by individual servers but this is of lesser importance to us.
Also, which Cisco solution would be required for iSCSI mirroring of SAN data from one site to another ? The throughput of the write-thru is only on the magnitude of about 50Mbps.
Thanks,
= K

In a SAN multi Targets(storage LUN's) can be shared and accessed by multi Initiators(hosts) Clustering software on the host or SCSI reserve methods are used to lock that area on the disk so only one write operation can be working at a time. For reads all can be readin at same time. There are many ways to balance the I/O's to the targets on the SAN. As for mirroring with iSCSI where there is a local SAN connected Target and a iSCSI connected Target the I/O is sent to both, local copy and remote copy for reason of backup, what the application is to do this could be as simple as NTbackup. If your really wanting to push a backup or replication of the data from SAN to SAN then you would use FCIP protocol along with a application data mover on the array or a package like Veritas.
