:/Developer/Examples/JavaWebObjects/AmazonClient

I couldn't find a list of what all these examples do, and since their names often don't explain the topic (how are you supposed to know AmazonClient is a WebService example?) I wrote a script that pulls out the "Overview" text from each one. Here are the details:


AmazonClient
The AmazonClient application is a simple application that asks you to enter the name of an author.Then it uses the Amazon web service to request a list of books by that author, and displays theresult. This example shows how to use the WebObjects Web service client to access a third partyWeb service.


CreatePlot
The Create Plot application is a simple application that displays dynamically generated graphs, counters and a pie-chart. All graphs are configurable on the fly by editing the dictionary in the text area. The dictionary is in a plist format. Data can be added to the pie-chart dictionary and the changes will be reflected.


FileUpload
This example application demonstrates the creation and use of WOFileUpload elements,allowing you to transport files from client machines to your application server (and theapplication, if required).


HelloWorld
The Hello World application is a simple application that asks you to enter your name. Then itdisplays a personalized message. It's a good example of how to dynamically generate HTML withuser input.


iShacks
This is an HTML based application that uses the JavaRealEstate Framework (also usedby the JCRealEstate example which is Java Client based).This example implements a simpleReal Estate site in which Agents make recommendations to their Customers aboutwhich Listings they should look at. There is also a general Listings searchmechanism, including the support of searching via Direct Actions. New Listings,Customers and Agents can be added to the Data Base. The edit pages for Listingsand Customers use component validation to make sure the field input is correct.WOCookies are used to implementand automatic login functionality.


JavaClientLauncher
Launch any Java Client applications (including Direct to Java Client applications) using a single Mac OS X application. Based on this example, you can easily build a double-clickable desktop Java application able to connect to any Java Client WebObjects application server. This application displays a URL dialog for connecting to a WebObjects application server and supports multiple languages all based on the project's properties.


JCDiscussionBoard
When the client starts up, it shows a login panel in which users authenticate with a name and password. New users can jump into a registration panel. While registering, users can choose whether they are administrators or regular users (which is something you would not do outside of an example, but it nicely solves the problem of setting up administrator accounts).After logging in, administrators and normal users will see different types of user interfaces. While administrators see a standard Direct to Java Client application, which was only customized with the help of the Direct to Java Client Assistant (see the rules in the user.d2wmodel file), non-adminstrators see a highly customized application which is much simpler, only allows postings to one board (no multi-board messages) and forbids adminstrative tasks like removing messages. Users can switch identity by invoking the Logout menu item in the Document menu at any time.


JCEntityViewer
After starting server and client applications, the user is presented with a choice of user interface options to browse data. Clicking on one of the choices opens more windows.


JCMovies
After starting server and client applications, the user is presented with a window to browse and edit Movies information.


JCPointOfSale
JCPointOfSale is a multi-window application to perform typical tasks in a video rental store (checking items in and out, calculating fees). The application presents the user with a customer selection table, which then allows the initiation of a new business transaction with the selected customer. The resulting transaction window maintains a list of fees currently owed by the customer and allows the user to update this list by checking out or returning products via modal panels.


JCRealEstate
When the client starts up, it shows a login panel in which users authenticate with a name and password. New users can jump into a registration panel. While registering, users can choose whether they are administrators, agents or customers (which is something you would not do outside of an example, but it nicely solves the problem of setting up administrator accounts). The example does not implement all security hooks desirable, see the JCDiscussionBoard example for more details in this area, but it makes sure that only the administrator user interface shows login names and administrator users (the properties/entities are simply hidden in the interface for the other user types).


JCRealEstatePhotos
This application has two primary uses. First, you can use it to upload files to the WORealEstate database. Second, you can use it to search for real estate listings. Unlike the JCRealEstate example, the search returns pictures of matching listings, rather than the listing information itself. Clicking an image in the scroll view displays more information about that photo and allows you to add it to the download queue.


JCRentalStore
JCRentalStore is a pure Direct to Java Client application which uses various customization techniques to enhance the client application. There are no client side classes or interface files in JCRentalStore. On startup the application presents the user with a query window containing a tabbed pane for all main entities the user can work with. In this window users can search for objects and open these in other form windows to edit them. Additionally users can open an enumeration window to modify the very simple entities.


JCStudios
After starting server and client applications, the user is presented with a window to transfer Movies between Studios. The user can trigger an action to buy all movies of a selected Talent for a Studio.


LongRequest
This example application demonstrates the creation and use of long runningrequest/response pages which enables web-based applications to perform lengthy tasks whileproviding feedback and means of interruption to the user.


PersistentSessionStore
The PersistentSessionStore application demonstrates one possible alternative session storeobject -- WXPersistentSessionStore. In WebObjects, the session store is the object thathandles the storage of your session state between requests. The default session store is theServerSessionStore, but that only stores the session while the app is running and cannot dealwith interruptions in service and consumes virtual memory. The persistent session storesolves these problems by putting the session on disk as a backup in the event the app dies orthe in-memory session times out.Description:Asynchronous ArchivingAt present, there are two subclasses of WXSessionWriter -- WXSynchronousSessionWriter andWXAsynchronousSessionWriter. The synchronous session writer is very straightforward and youmay find it easier to start by looking at this class first. Once you understand what's goingon with the synchronous version, you may then want to look at the asynchronous version. Theasynchronous version employs a "write queue" into which are placed NSData objectsto be written to disk. A separate thread is forked to handle writing these archivedsessions. When a new session archive is placed in the write queue, the thread which does thewriting is signalled and the data is written to disk asynchronously.Session TimeoutsThe scheme employed by this example allows for sessions to reside in memory and on disk tosupport a fail-over mechanism. To restore a session, we first attempt to get the sessionfrom the server session store and, if that fails because the session has timed out, then weattempt to get the session from disk (via the WXPersistentSessionStore class). The sessiontimeout scheme employed by the server session store works the same way it always has in WOF,but the time out scheme for archived session is managed by a separate class calledWXArchiveTimeOutManager.The ArchiveTimeOutManager is a utility class employed by theWXSessionWriter superclass. Its job is to periodically scan the session archive directoryand purge any stale session archives. The user default WOSessionArchiveTimeOut can be usedto adjust the time which any archived session lives on disk; by default this is set to 86400seconds (1 day). The timestamp on the file is used to determine if the file is stale. Tokeep system resource consumption minimal, the scan and purge activity happens on a separatethread and is only invoked every 600 seconds (10 minutes); this period is hard coded intothe class.


PetStoreEJBClient
PetStoreBeans, PetStoreEJBServer and PetStoreEJBClient contain thestandard Sun PetStore. PetStoreBeans contains the beans.PetStoreEJBServer is a WebObjects application (EJB-tier) which alsoruns a EJB server. PetStoreEJBClient contains the WEB-tier.


PetStoreEJBServer
PetStoreBeans, PetStoreEJBServer and PetStoreEJBClient contain thestandard Sun PetStore. PetStoreBeans contains the beans.PetStoreEJBServer is a WebObjects application (EJB-tier) which alsoruns a EJB server. PetStoreEJBClient contains the WEB-tier.


PetStoreWOJava

RealEstateApp
This example demonstrates how entity beans are deployed for use in a WebObjectsapplication. The beans were generated by the EOBeanAssistent from the EOModelfile that is part of the RealEstateApp project.The example is not intended to be a tutorial on writing Enterprise Java Beansin general.


RelatedLinks
This example application demonstrates the use of WOHTTPConnections, WORequests, and XMLfor communication between web sites. This application takes a qualified website URL andcommunicates with the Netscape related-link site (www- rl.netscape.com) to get a list ofsites with related information.


SchoolToolsClient
Together, SchoolToolsClient and SchoolToolsServer make up the SchoolTools example. The Client is a WebObjects application with JSP and Servlet integration. The Server is a WebObjects application providing a SOAP RPC service. The Client and Server applications communicate using the AXIS toolkit.


SchoolToolsServer
SchoolToolsClient and SchoolToolsServer make up the SchoolTools example. The Client is a WebObjects application with JSP and Servlet integration. The Server is a WebObjects application vending a SOAP service. The Client and Server applications communicate using the AXIS SOAP toolkit.


SophisticatedDatabaseExample
The SophisticatedDatabaseExample application maintains a simple universityweb site that allows students to enroll and sign up for classes.The site is administered by an "admin" user who adds and deletes students,classes, classrooms, and teachers.The purpose of the example is to demonstrate the moresophisticated modeling techniques, such as inheritance, flattened attributesand relationships, and the use of multiple models.


ThinkMovies
The ThinkMovies application allows you to search and browse the contents of the example Movies database, which is supplied with WebObjects. This application is implemented in Java and uses Direct Actions. Direct Actions enable bookmarkable URLs and session-less applications that do not require clients to be bound to a session, and hence be bound to a particular instance of a WebObjects application. Another feature of the application is the ability to add reviews/ratings of the Movies, providing the essence of a "public poll" on the quality and popularity of each movie.


VirtualStoreLite
The VirtualStore Lite application presents potential customers with a virtual store. In this store, users will see the merchandise using a QuickTime virtual reality movie. Three different PowerBooks are available in the store. Users can select a PowerBook from the virtual reality image and then indicate the quantity to order.VirtualStore Lite demonstrates the integration of the WOQuickTime element with a WebObjects application. The QuickTime plug-in must be installed with the user's browser.


WOExamples
The Component Element Tour allows you to see and try a variety of examples where components are used to re-create the basic functionality of many of the WebObject Framework's built-in dynamic HTML elements. All example components in this tour are created as non-synchronizing components, and they almost all employ WOComponentContent. Furthermore, only the primitive dynamic elements such as WOString, WORepetition, WOConditional, WOGenericElement, and WOGenericContainer are required to recreate any of the basic HTML dynamic elements. These components have the basic functionality of their dynamic elements counterparts but can be easily modified and treated as components.Description:Simple Dynamic ElementsActiveImages, Hyperlink, Image, LocalizedStrings, and Optional Containers examples demonstrate simple dynamic elements. You can interact with each action-oriented element to see how it feels to the end user. Each time you click, you will be taken to a different page; simply use the back arrow button to return to this page.Dynamic Form ElementsExamples of various form- related elements are:BrowserFramesInline FramesMultiple Submit ButtonsPopUp ButtonYou may interact with each element in some way (either typing into it or making some choice(s)). You can see the results by clicking the WOSubmitButton or WOImageButton to submit the form. The values for every form element will be displayed. You can use your browser's back arrow button to return to the previous page.WOExtensions ElementsThe CheckBox List, Nested List, and RadioButton List examples demonstrate three of the more generic WOExtensions components. There are many more components available in WOExtensions (most of which support DirectToWeb development). The source for all WOExtensions components is provided with this release.


WOInheritanceExample
Entity inheritance is more complex to set up and is not needed very often, but when it is, you can usethis example to better understand how it works and what to expect. Three different styles of entity inheritance are presented: vertical, horizontal, andsingle-table. The databases for each style of inheritance contain the same data to provide a goodcomparison of the SQL generated to fetch inherited or abstract entities. Users select an inheritancestyle from a list on the initial page of the application and add, associate, group entities as explainedbelow. The app itself behaves the same regardless of the inheritance style chosen - the educationalvalue of the example comes from studying the entity and inheritance diagrams, the EOModels, the SQLgenerated by various user actions, and the structure of data in the database for each inheritance style.
