Java-Help-System generates an advanced help system for JDK and J2SE docs automatically without speeding your any time and energy, which even does not occupy hard-disk space. 

Main features of  Java-help-system generated
  1. Similar to MS html help contents but with more features, which displays not only html files, but also all of text (such as java, policy and xml) files, class files, jar and zip files (refer to picture 5, 6, 7).
  2. Contain four tables (refer to picture 1 - 4), which offer you the most convenient environment for using JDK docs. 

Java-Help-System accelerates your programming speed and qualities because you can retrieve java information much easier and faster.

  • Four tables
    1. table Contents
      The page contains 6 top items (i.e. Online, Document etc), you can add user top items for advance use.

      (picture 1)

    2. table Index
      List-box on the table contains all JDK documents (html files without their file extensions), you can input a short name to find a class (i.e. Frame), a tool (i.e. javac) and any info required.

    3. table Search
      Button Search at top is used for searching files by file extension.
      Button Search at bottom is used for searching documents by short name.

    4. table Favorite
      You can add a topic currently displayed as favorite topic and re-display it late.

  • Displaying files.
    Besides html files, the help system can display class, jar, zip and all text files.
    1. class files
      class file is displayed with its scope code.

    2. jar and zip files
      They are extracted in memory and displayed as their compressed structures.

      (picture 6)

    3. text files
      All text files are displayed in plain format (similar to notepad)

With the new Java-Help-System standard edition, Java programmers can now use online help that rivals traditional help systems on other platform of Windows. Aimed at Java developers and technical writers, creating effective JavaHelp provides a very concise guide to you.

The help system provides hyperlinks and browsing capabilities, does a good job at orienting the reader to JavaHelp and how it relates to these documentations. It also includes a short, useful section on project planning for online help. It shows how the JavaHelp standard uses HTML, jar, zip and other files to structure content layout (for such options as navigation and the table of contents; help content itself is organized into HTML pages). Creating Effective JavaHelp works through a sample help system from Sun and shows you how to create a simple, custom help system to illustrate these concepts, the Help System ventures into a discussion of the JavaHelp APIs, which allow a program to call up context-sensitive help at run-time. Other sections show how to take advantage of more advanced help features, like using secondary windows to display content or using embedded help within custom abilities. The Help System ends with reference material on relevant tags, plus the JavaHelp API itself.
Chances are JavaHelp won't change the way you create help systems. (As the Help System notes, third party tools will actually let you deploy help systems to JavaHelp automatically.) But this compact text points out the differences and advantages of JavaHelp for creating online help on the Java platform. Whether you are a technical writer, developer, or project manager, you'll want a software of  JavaHelp to see the future of online help for the next generation of Java applications.
Effective, instantly available online help is a requirement for today's interactive applications. Until now, Java application developers have been forced to develop their own help system. That's no longer necessary. With the release of JavaHelp™, there is a complete and standard online help system for the Java™ platform.
The help covers the main features and options of JavaHelp. It shows how to create a basic JavaHelp system, prepare help topics, and deploy the help system in an application. Written for all levels of Java developers and technical writers, the Help System takes a chapter-by-chapter approach to building concepts. It imparts a complete understanding of how to create usable JavaHelp systems and integrate them into Java applications and applets.

We continues to roll out as fast as you can use. The new Help System, currently in beta testing, includes components, applications, desktops, and HTML pages. (That's a big target.) The Java Help documentation envisions a Java-Help-System written purely for JDK. That means you can embed items within it or transport to another destination.
The primary component of the Java-Help-System seen by a user is the he lp viewer, which comprises a toolbar, content pane, and navigation pane. (Java Help relies heavily on swing user-interface components.) The contents of the help viewer ought to be familiar to anyone who has interacted with a help system. The conte nt pane displays help topics. The navigation pane is a tabbed pane that lets a user select from among the table of contents, index, and text search options.

Java Help permits a single help system to support varying "navigational views" of help content. The navigational view is a description of how a particular kind of content is to be viewed. In that sense, it is metadata -- data about data. For example, a navigational view is defined by (among other things) its format (how it is to be shown) and data that identifies the format and location of the view. A navigational view is implemented by a Help Navigator, which is a subclass of the JHelpNavigator class (a swing component).
The Java-Help-System already understands several n navigational views. The table of contents, index, and search information (displayed in the help viewer) already have navigational views defined. Java Help provides mechanisms for registering new navigational views. Consequently, the diversity of data permitted, and the means by which the data is viewed, is limited only by developers' imaginations.

The data structure that carries all the information needed to provide a view into a help system is bundled into a help file. Note that there are two "loose" terms at use here. First, a Help file isn't necessarily a file, in the same sense as files that you store on your hard disk. A help file could be bound into an application, for example. Second, it's probably more accurate to say that the information is rooted in the help file. The structure of a help is Extensible Markup Language data. The data points to the URLs from which you can find the info necessary to build the help system.
Here's an example. One portion of the help file points to yet another structure called the Map file. A Map file is a series of "key = value" pairs. Each key is a help topic (i.e., an entry from the table of contents), and the value is the URL of another file that stores the actual content that the system will display when the user selects a table-of-contents item.

The help browser has a storage facility on your hard drive that stores graphics and text from web sites that you visit. This storage facility is called the cache using very little memory, or temporary internet files. The reason web browsers have a cache is that it is quicker and easier to load images, applets, etc. from cache on your hard drive than downloading them again. Over time, your browser's cache gets full and the information gets outdated. This can cause problems with Java applets and can result in that Applets are freezing or not working at all. The solution to this is to clear cache and reload the page. If this does not work, try clearing your cache, closing your browser and then revisiting the page.
The upshot is that the data structures used by a Java-Help-System are flexible enough to permit a wide variety of delivery scenarios: Help can be bundled into an application, help can be a separate file outside the application, help can be pulled in from across the network, and so on. The architecture is initially daunting, but it looks as if it will serve the broad (and ever-broadening) needs of Java applications and applets.
