Hi,
The Java Petstore 2.0 has a CAPTCHA (see http://en.wikipedia.org/wiki/Captcha for the definition of a CAPTCHA) which is used when a user is uploading a pet for sale to the petstore. The captcha is used to avoid automated graffiti on the community driven content of the petstore. The captcha requires a human to look at the image and type in the words, so it shows this common use case where web sites want to avoid an automated program from being able to post to a site.
All the source code for the captcha is included in the petstore download at
https://blueprints.dev.java.net/petstore/ This is useful code to use in your own applicatons as captchas are becoming more common in web applications
Yutaka Yoshida has a blog entry that discusses the captcha at

  • Who can tell me how 2 build a application in win32?

    i use jar to create a .JAR archive, but it can't lunch by javaw.exe.
    I create it by:
    jar cf test.jar test.class
    when i double-click the test.jar icon, win32 doing nothing.
    i'm sure the test.class is ok, it can run by java.exe
    how i can make the test.jar run?
    thanks.

    Hi,
    first, you use notepad to create a text file 'manifest'
    with following contents:
    Class-Path: test.jar
    Main-Class: test
    then, you run:
    jar -cvfm test.jar manifest test.class

  • How to build an extensible application

    I am currently looking into how to build an application that allows other developers to implement an interface (say DictionaryProvider) and provide a jar file with this implementation and have my application automatically find all classes within a specific directory (under any jar) that implement this interface, instantiate an object and perform some operation on the object. I see in java 1.6 that there is a nice way to do this but I have not seen similar examples in Java 1.5. My basic question is how do I allow users to implement an interface and then at run time find all classes that implement this interface and instantiate an object of that type?

    DrClap wrote:
    Right. Don't waste your time loading every single class in the jar, there's probably a lot of supporting classes in there. Instead do what the XML people did and use the Services API. For an example, look at how Java loads a DocumentBuilderFactory. The third bullet point there shows you how it's done in that case. You'll find that TransformerFactory has a similar process.Hmm. I think the OP wants people to be able to drop in previously unknown jars that implement some interface, and have that work without that jar creator needing to do anything else. I'd find a property file or manifest entry easy enough, but I can see his angle.
    I have heard about another way that I haven't tried, which is to use annotations and spring - but I guess that's just as complicated as writing entries to a property file. So the only plug-and-play method without the external jar producer having to do anything but implement the interface seems to be ClassLoader workarounds...

  • How work with Large Applications in JHeadStart?

    work environment:
    JDeveloper 11.1.1.2.0
    11.1.1.2.37 jheadstart
    Hello, my problem is:
    I have a database of over a hundred tables, I worked with jheadstart into a single application in JDeveloper with a model project and a project ViewController, but now I want to add developers to the same system. So I do not know what I should do to divide the work on my team.
    I started by dividing the database schema in submodels, but up there.
    I need some suggestions, some methodology to do this. It is worth mentioning that we will use a custom menu, custom skin and custom security.
    I do not know what to do, if divided into several projects: Model and ViewController, or split applications of JDeveloper, or if I need a versioning system.
    If there is any link that I provided where there is much information about it, would greatly appreciate.
    Help please.
    Thanks.

    Rosario,
    You should definitely use a versions system, SubVersion is a good choice.

  • How do I build an application that will run without being installed?

    I have seen some of the prior posts on trying to do this, but most of them were older, so I'll ask:
    Using 7.1, how do I build an application that will run without having to install the runtime engine? I have a client that wants to run serial port monitoring VIs to watch some custom hardware we built for him. His IT dept. won't let him install anything. If I could make this VI run off of a USB thumb drive without needing anything installed on the system it would be ideal. Space is not a problem, so I could include any runtime files needed. Can anyone tell me how to do this?
    Thanks

    Under what operating system was it running under back in the 90's when it was working?
    I think that starting with NT platforms (applies to 2000 and XP, but not 9x) the hardware abstraction layer (HAL) prevented direct I/O to serial ports. Serial port related code that ran fine on 3.x and 9x would not run under NT platforms without modification.
    Just some food for thought, do not know if it applies to your situation.
    Good Luck

  • LabVIEW 8.6 propositions on how to build application that acts like reader form specified field dependent on which values been selected

    Hello everyone!
    I am newbie to LabVIEW with some previous experience programming in different languages.
    My goal is to build the application that upon my selection needs to give specific values from previously filled and prepared file.
    For example, I have different types of operations (milling, drilling, turning..) and different grades (type) of steels (Uddeholm steel grades: NIMAX, IMPAX...and about 40 of them). For every operation there are different input data (Coated insert, uncoated). Based of those information application should give out cutting speed and feed rate data that are stored in some file. I understand I can do it in Excel spreadsheet or LV spreadsheet, I would prefer LV because of portability to systems without Office installed on them. I also understand that all those issues concerning input data for output results I can easily solve with case scenario.
    Main issue is decision between different types of files that I can easily address like 2D matrix to get required data, which and how to do it.
    I would like to know what I should acknowledge first before doing any further work?
    And does someone have some simply prepared VI on which I can work my way on?
    If you are willing to help me with guides I would be happy to answer any of your questions.
    Vedran Galeta

    Thank you very much for your reply.
    This application that I am working on is completely static due to communication. It simply needs to provide entry in table depending on selected inputs in front panel, and of course display it front panel. I know what I need to do, as well as the structure. Only thing that I don't know yet how to do it in LabVIEW.
    When I mentioned "LV spreadsheet" I meant on read from file option, you got that right.. The thing is that now I have large amounts (not large in acquisition data point of view, 5 spread sheets, with 45 rows and 15 columns) of data saved in Excell, and my goal would be to get that data in LabVIEW application, for the ease of access. And still leave that xls file as is, due to all connections that he have with smaller xls files. So in compact version of the story I am going to use save as comma separated (or tab, that depends of course) values from Excell with or without extra editing of created file in order to load that file into prepared program structure in LabVIEW. After I manage to do that, of course I will work my way for all other extras that I am gonna put eventually in program structure. So this would be like a backbone, I know it sounds simple. As a matter of fact I would probably be finnished allready in VB but highest demand is to do this in LabVIEW, and I am fully down with that.

    Vedran

  • How can I build an application that deploys my shared variable library?

    I have a VI that I want to build into an application and put on a non-development machine. I am using a shared variable which obviously is contained in a library. In the VI itself I can deploy the library by specifying a path. Is there a way to build the application so that the library is deployed automatically when the .exe launches? I want to get away from having the end user to have to know where the library is and set the path correctly.

    Hi Troy,
    Sorry, but I think I missundersood you.
    I think you have to deploy the library programmaticaly by using the Application Control functions (OpenAppRef, InvokeNode)
    I didn't test this but the following picture shows how to start:

  • How to Build and Deploy Flex application in EP6

    Hi All,
    Can anyone tell how to build and deploy Flex application in EP6.
    I want to build a normal application in flex and present it through iviews. How do I configure my Iiview to have flex component running in Portal Environment.
    Thanks

    A good book to start with is Enterprise JavaBeans by Monson-Haefel (O'Reilly press). It covers deployment of EJBs on J2EE servers. Also check out sites specific to your server, sometimes they have specific requirements (like Weblogic).

  • How can I build an application that calls functions in a dll if the associated hardware is not present?

    I am trying to build an application that use the "Call Library Function" node to call functions in a dll.
    The dll was provided by a third-party and includes functions to drive an I2C communication board.
    The problem I have is that the dll does not not properly because the hardware is not present.
    Therefore when I load the VI a broken arrow is displayed and when I am not able to build the application.
    I will not be running the application on the PC where I build the application, therefore I want to be able to build the application on a remote PC that has not all the hardware installed. Once the application will be build it will be installed on the target PC that has all the hardware.
    How can I make the application builder to build the application event if the dll is not properly loaded? (the dll will be properly loaded on the target PC)
    I want to do this on LabView 5.1.1, any ideas?

    Some .dlls don't try to attach to the driver when loaded.
    I've worked with both and unfortuately, I've not figured out a way around this problem.
    You could possibly use the Conditional Disable structure around the dll calls so they would not be loaded unless you're in the runtime engine. But i've not tried this so I don't know for sure if it's possible.
    Anyone??

  • How to build applications with a non standard stlport

    Hi,
    I have a separate compiled version of stlport that I am supposed to use to build my application. In other words, I do not want to use the stlport that comes with the Sun compiler. I am aware of using -library=stlport4 when I use the default stlport that comes with the compiler.
    What flags/options should I use when I have my own stlport (libstlport_sunpro.so) library?
    I am using Sun C++ 5.6 2004/07/15 on SunOS 5.8.
    Pls help.
    Thanks
    Edited by: Sreeni_dd on Jul 23, 2009 12:50 PM

    Details are in the C++ Users Guide, section 12.7 "Replacing the C++ Standard Library". Here is a summary.
    1. Add the option -library=no%Cstd to disable both libCstd and STLport.
    2. Add a -I option that points to the include directory for the stlport headers you want to use. (Do NOT use the headers in the compiler installation.) Example:
    CC -library=no%Cstd -I/path/to/stlport/include -I/project1 -I/project2 ... If the compiler doesn't always find the headers, put the -I stlport option at the end of the other -I options, preceded by a -I- (dash eye dash) option. Example:
    CC -library=no%Cstd -I/project1 -I/project2 -I- -I/path/to/stlport/include ... This procedure is not optimal, since you would like to search STLport headers before searching other headers. use the -I- option only if needed.
    If you have file name conflicts with the STLport header files, you will need to add a set of symbolic links *.SUNWCCh as described in the C++ Users Guide.
    3. For link commands, add a -L option pointing to the directory where the compiled STLport library is located. Assuming this library is called libstlport.so, also add the option -lstlport. Linking a static libstlport.a is not recommended if your program uses any shared libraries. Example:
    CC -o myprog *.o -L/path/to/stlport/lib -lstlport

    anyways, is it possible that whenever guest logins into the system, the windows page bounds configuration like front panel bounds in labview be fetched so that the same will be configured to the vi's front panel programatically.
    by doing this the windows components will automatically get hide.
