Low cost Java IDE

i'm new to java but i used to program a little in C++ so the core of the language is not that difficult to learn. basically what i am going to use it for is discrete math (that seems kind of wierd, i should be using something like Fortran 90). anyway i was wondering if anyone had any knowledge about low cost IDE Java compilers, something like a student version of an IDE compiler without all the features that i cannot even begin to understand because i was a math major in college and not a compsci major. some one told me (actually my psychiatrist of all people) that SAMS publishing company might publish a Java tutorial in book format with an attatched CD that is a Java IDE compiler. basicaly i don't want to have to learn how to compile and link and change classpath variables from a comand line. i'm lazy, so sue me.
anyway any advice would be appreciated.

No it doesn't! People who hightlight their knowledge
of IDE 'X' on their resume inevitably don't know the
language, they only know the tool. You take away their
tool and they have no idea how to write code. This is
true regardless of platform or language.
I agree with most of what rtg54 says here, but sometimes when people list an IDE they really DO know the language and the IDE. "Invariably" might not be the right word here. The probability might be high that listing an IDE means little understanding, but it's not 100% certain.
Standard (Java) IDE Advice:
As someone new to Java this person should not be using
an IDE until they can install the JDK, setup
classpaths, run 'java' and 'javac' from the
commandline, navigate the JavaDocs and manage packages
manually, i.e. through a command line. Yes, this will
result in a higher initial learning curve, but will
pay off greatly in the future. If they want to use a
simple text editor like JEdit or TextPad for syntax
highlighting that's fine, but by using anything more
like JBuilder, Eclipse, IntelliJ, NetBeans, etc.
they'll be doing themselves a huge disservice.I agree with all this. - MOD

  • Simple and low cost design tool

    I am looking for a simple (relatively) and low cost(or free) tool, site, software that can help with the design of space. Something that essentially can take a space and place objects to help figure out the layout and design.  Any ideas?

    Hi,
    Some companies have budget problems and are having to reduce their cost of operation.
    Have you ever heard of open source tools? They can do the job easily and less expensive than proprietary solutions that cost a lot of money.
    You can have a look at a good ETL open source program called Talend Open Studio: it is user-friendly but also has advanced features intended for technical users (java debugger, code injection…). It can perform data migration and ETL as you wrote in your first post.
    The website is [http://www.talend.com/download.php|http://www.talend.com/download.php] to download the open source program. They have a forum and documentation you can read. Tell us what you think about the software.

  • Simple Object Modelling and Java IDE for OSX?

    I haven't been technical for a while and I want to refresh my Java and object modelling skills. I'm looking for two things. If I can find both in the same environment so much the better.
    1) A basic UML modelling tool. All I really care about is describing a medium size object model: classes, sub-classes, attributes, relations, etc.
    2) A basic Java IDE. Don't need EJB or anything complex. Just want to compile run and debug simple Java programs.
    I down loaded Net Objects but it seems like overkill for what I want. I looked on some open source sites but almost nothing was native to OSX it all ran under Windows or required a Java virtual machine. Actually I guess that's another question, is there already a Java virtual machine as part of OSX or do I need to download one and if so which would be the best.
    I'm willing to spend a few $$ but free stuff would be better and no more than $50. So far I found one product native to OSX but the starting cost was $400+ for a five person license.

    In case anyone has the same question, I just found this very nice tool on the Apple web site called Visual Paradigm for UML:
    http://www.apple.com/downloads/macosx/development_tools/visualparadigmforumlente rpriseedition.html
    I'm still getting to know it but this is exactly what I was looking for. Fairly easy to use if you already know OO but not as complex as some other tools and works well on the Mac.

  • Low-Cost data migration and ETL tools

    Hi, Im building a database for my company. We are a rather small size book company with a lot of references and still growing.
    We have a Mysql database here and are trying to find some good tools to use it at its best. Basically we are just starting up the database after dealing with Excel: we had a size problemu2026 So im trying to find a program that will allow us to do two different things: the migration of our data from the old system to the new one and a specialized software to perform ETL (Extract, transform and load) on our database.
    About the price of the tools, if we were one year ago, the accounting department would have been pretty relaxed about this. But today, we have some budget restrictions and therefore need a low cost tool. So could you give me some advice on a good data migration and etl tool for a low cost?
    Thanks for your help.

  • Low-cost OS X purchase option for obsolete iBooks?

    I have some obsolete iBook G3 500 mhz / 10 gig / 128 meg / CD and iBook G3 700 mhz / 20 gig / 128 meg / Combo. I have been thinking about just throwing them in the trash. Someone tells me, no no don't do that, you can sell them on ebay for ... $50 each or so. Woo.
    (Oh, and yes a bunch of them do have that powerful sweaty "iBook Stink" keyboard problem. I am not sure what the official Apple solution is. Anyone tried applying Old Spice to a keyboard?)
    Well the only way they are going to be useful is to run at least a newer OS than the 9.2.2 / 10.2 they have. And If I have to pay $120 per license for 10.4, there's really no point starting this exercise and I should go back to the original plan, electronics waste disposal. Preferably with a sledgehammer.
    Microsoft has a way to deal with this. They practically give away Windows XP and now Windows 7 for low-cost rebuilt PCs through their refurbisher program, and the licenses cost something like $5-10 per computer.
    Microsoft Refurbisher Program
    http://www.microsoft.com/refurbishedpcs/programs.aspx
    Is there a refurbisher licensing program for cheap old licenses of OS X, from Apple? I am not finding anything.
    But I went through this previously. I'm mainly just looking for an update.
    I wrote to Steve directly a few years ago asking about free or low-cost OS X licenses for these obsolete Macs, and Apple responded with the name of an electronics recycler near me. (Really!) Once support ends in about 3-4 years, who cares? Apple sure doesn't. And besides, you should be buying "the next one", to stay all hip and cool and "with it", anyway.
    Still looks like trashing them is the best option, as trying to sell them for $20 per machine with 9.2.2 / 10.2 is not worth my time to pack and ship them..

    No? Through forced obsolescence you are removing older computers from the market and obliging people to buy newer, so faster turnover and sales of newer (unless they decide that they give up on Macs).  Fast forward 5 years. Scenario where Apple sticks with their pattern of no longer selling old versions, nor will they be available on disc because it's all download.  How will you get hold of Lion 5 years from now to make a 2008 Mac functional in 2017?  I suspect the used Mac market will really be hit hard because our current means of updating older Macs by finding old discs on the used market will be gone.  Right now I can buy a 6 year old OS (Leopard) to make my 10 year old Quicksilver still pretty functional in 2012.  I am not sure we will be able to do the equivalent in a few years from now becuse we won't have a means of getting hold of the new system versions unless you buy one now and stick it on the shelf "just in case".
    Only thing I can think of is maybe a Family Pack install Disc.
    Technically those are for family use, not selling 5 computers to anybody on e-bay.  In that regard you'd be no better off with a family pack than a single installer.

  • Best Low Cost Camcorder for FCP?

    I'm going to take back a Samsung D453 camcorder because it has time code breaks during capture. Does anyone have any recommendations for a low cost DV camcorder that is supported by Final Cut Pro?

    Actually, recording timecode on a tape might have been a good idea with analog crash recording, but it does not make sense on DV camcorders. If nothing else you end up recording twice on the tape which increases wear on the camera heads and doesn't do much for the tape either.
    As an alternative to blacking tapes, simply record the first 30 seconds or so of the tape without images. Use a bars and tone if the camera can generate one. Otherwise use the FCP version. This gives you enough preroll area for capturing all material after this point.
    Once into the tape, just make sure when you stop recording, the heads are in a position that will allow them to pick up the timecode and continue on. As long as you do not rewind and review the footage you are good to go. If you must rewind & review, stop the play back a few seconds short of the end of the previous shot.
    So to recap. Generate bars and tone for the first 30 seconds of the tape then give your self enough preroll on each shot as well as an additional few seconds at the end of each shot.
    If you must review a shot/scene in camera, stop the tape before the end of the scene so the camera can pick up the timecode as it moves on.
    Good luck.

  • Low Cost Load Balancer / Reverse Proxy for 2 Oracle Application Servers

    If you have 2 OAS and you need to setup a load balancer / reverse proxy infront of it and you can't use webcache or a hardware load balancer what's the best way to setup a low cost solution that would preserve your session state if you have a OC4J clustered application running on the MT?

    Just a quick answer, please:
    If you think about Oracle WebCache as a general application, you will find some useful Technical White Papers on http://otn.oracle.com/clusterware They will explain, how Oracle Clusterware can be used to protect any kind of application.
    In general, Oracle Clusterware and Oracle WebCache must be installed on the same set of servers (cluster nodes) in this case. Regarding the question of whether or not you can re-use your 2 SUN servers: It depends.
    Oracle Clusterware requires shared storage and a private interconnect. Your current infrastructure might need to be reviewed and enhanced in those regards, especially, since your servers are geographically separated as you said.
    Just some ideas. Thanks.

    APPLE KINDLY PROVIDE THIS FEATURE AS UPDATE SOON,COZ I WORK ON EXCEL N NUMBERS IN MY IPAD IS DEAD WITH OUT FILTER FUNCTION,I CAN NOT TRAVEL WITH MY IPAD DUE TO THIS REASON,AS I HAVE TO BE IN FIELD WITH SALES FORCE SO I BOUGHT IPAD.

    Probably you know that the new version of Numbers for iOS uses the filters created in the Numbers for Mac version.
    It's not the best solution but it helps (of course, if you have a Mac!)

  • Java IDE Security Issues

    I'm evaluating Java IDE's. My boss wants me to evaluate IDE security issues. I can't think of any issues, or how an IDE can have anything to do with security, but didn't want to sweep it under the rug without asking all of you security experts.
    Are there any security concerns when selecting a Java IDE?

    Yeah, you confirmed what I already knew I suppose.
    Unfortunately, I know nothing if this organization, as
    I'm only consulting. The management here INSISTS that
    security be addressed, but I think it's out of scope
    for Java IDE selection. Thanks!In that context, things like "supports HTTPS and ssh access for remote development" may be exactly what they're looking for. It lets managers say "Yes we considered security in making this purchase, and yes the developers of this tool take security seriously." Doesn't mean that security is ever going to impact the actual use of the product.
    Remember that a portion of any management decision goes to insuring you can show a good-faith effort to avoid problems, when/if they happen down the road and someone's looking for a fall guy...
    Good luck!

  • Java IDE Internationization Tools

    Is there any Java IDE(s) out there that have built in tools to support internationalization?

    I'm using 2.0.1. It's not a plugin - look at \Source\Externalize Strings... menu.
    Regarding Websphere - I can only imagine that it works as well or better than base Eclipse - but I'm not using WS right now, so you'll want to check for yourself.

  • Java IDE (JBuilder) cannot find J2ME's API and packages

    Hi,
    could anyone help me with this?
    I went to sun's java web site, and I downloaded and install the latest version of the wireless toolkit. I need to create a windows application that can send/receive MMS messenges, and hence the need for the J2ME's API and also WMA's API.
    However, even after I installed the wireless toolkit, my Java IDE (JBuilder 2005) cannot detect any packages like "javax.microedition.*" or "javax.wireless.*" etc etc
    Is there a place where I can download/purchase J2ME. Please be patient with me because I am a newbie in the world of J2ME... thanks :)

    When you configuring your project in JBuilder just add some jar (which you need) from wtk library in section "include"
    Project properties
    Paths
    Required libries
    and add here addition j2me libraries.

  • Java IDEs

    Hello,
    I am interested in getting some feedback on java IDEs. Is the Eclipse, Sun Studio, or Netbeans IDE better for developing desktop, web, and mobile java applications.
    Secondly, are the books available at bookstores on IDEs like the Netbeans Field Guide worth the money, or is the online user's guide better?
    Lastly, what are some good books on developing GUI's?
    Thank you.

    Secondly, are the books available at bookstores on IDEs like the Netbeans Field Guide worth the money, or is the online user's guide betterYou generally use an IDE to make your life easier. It is not science, most if not all functions will speak for themselves. The question that remains is "is this and that possible?" When you see yourself faced with that question, use the help and if that fails: there is always google.
    So my opinion is no: you don't need a book for any IDE.

  • Good low-cost widescreen monitor for one-screen editing?

    Hello, I'm on a tight budget, looking for a widescreen monitor that is a good blend of low-cost but good quality (if possible!).
    I will be doing all my work off this single monitor. I will unfortunately NOT be able to have a dual-monitor setup, nor have an external reference monitor. I will be editing HDV footage.
    Any suggestions? Thanks!

    It is a PVA screen with dual DVI and a D-sub connector.
    I use three of them and they give me a good BFTB, "Bang-for-the-Buck".
    If you consider the various panels in use, they go from low to high in quality, TN >> PVA >> IPS.

  • Which is the best low-cost camera for my use?

    Hi everyone. Been busy and off the forums for a while, but need your expertise once again.
    I just found out that the Panasonic HVX-200p that's been on loan to me for 2 years has to be returned. Since I run a non-profit, I am thinking about asking my major donors to buy one for us. So, the question becomes which one? I own the CS4 MC, and you can see my other info in my profile.
    I only do educational-type videos in an interview format against a green screen so far. I've been capturing direct to OnLocation via 1394 FireWire at 720p/60fps and editing in an HDV 720p/30 sequence. I sometimes do "man on the street" segments (capturing to OnLocation on laptop). I integrate numerous PSD graphics as educational slides, a lot of AE projects I get from videohive and customize, render, & import into PP, and motion backgrounds like Pond5's weekly free stock footage (much of this stuff gets resized, of course). I do some scoring and some SFX and export the audio to SB for touchup. I use a bunch of Lowes/Home Depot worklamps with fluorescent bulbs for lighting the subject and background. I key my backgrounds using PP/AE Dynamic Link. Oh, and I'll need a lapel mic and a tripod, too. I would prefer not to rule out shooting at 1080i/p at some point.
    I export H.264 highlight clips which get uploaded to Vimeo and embedded in our website using prettyPhoto features. Ultimately, the finished PP project is exported as MPEG2-DVD, finished in Encore, burned via ImgBurn. If you want to see a good example, watch this http://vimeo.com/23346431. Caution: this is religious material. Be sure to repent before watching
    So, there's not really much heavy lifting here. But when it comes to what is the minimum I need with the options of capture formats, etc., I'm clueless. I've read about problems with AVCHD, and although low-cost, is it really a problem for what I do? I trust this forum more than online reviews, and I'd appreciate recommendations of specific models and where to buy, if possible. Also, what about used cameras? Please remember, the budget is tight.
    All suggestions and questions are welcome and very much appreciated.
    Paul

    Actually, two things surprise me in your statement and one is simply incorrect:
    As for Broadcast quality..... a little station called CNN - you might have heard about them bought 250 of them from Panasonic about a year ago.
    First, that CNN would buy JVC cameras not from JVC, but from Panasonic.
    Second, there are no JVC cameras on the BBC approved list at all, see http://downloads.bbc.co.uk/commissioning/site/BBC_Approved_HD_Cameras.pdf and the only affordable ones on the list in the handheld category are the Canon XF300/305. Maybe that is the reason the BBC bought 350 of these. Even the Sony XDCAM EX is only accepted in combination with a 50 Mb disk drive, not in the native 35 Mb format.
    The BBC approved list is a list that most broadcasters adhere to, including CNN, Discovery, ARD and NGC.
    The JVC GY-HD100U is definitely not acceptable for HD, and in no way HD broadcast ready. But that CNN bought that number of these cameras is probably caused by the fact that they think these deliver better quality than regular phones. And it does not use XDCAM, but a very simple HDV codec, limited to 1280 x 720 resolution. See http://pro.jvc.com/prof/attributes/specs.jsp?model_id=MDL101539&feature_id=03
    This simply means that the Canon codec is very acceptable to the BBC for HD programs. The XF100 uses the same codec, but is only a single sensor camera and for that reason alone not approved by the BBC.
    Paul, if you can live with the limitations of a single sensor camera - and given your intended purposes, I think you can - the JVC does not even come close and the XF100 material will be hardly worse than the XF300/305. To the untrained eye the results are almost the same.
