         Use Java to write application logic; Use HTML5 to render the UI;

         {@link net.java.html.json.Model Animate an HTML page from Java}
jtulach@668
    56
         (see <a target="_blank" href="http://dew.apidesign.org/dew/#7212206">Duke being rotated</a> by CSS);
jaroslav@543
    57
         Use {@link net.java.html.json.OnReceive REST} or
jaroslav@543
    58
         <a href="net/java/html/json/doc-files/websockets.html">WebSockets</a>;
jaroslav@543

         interact with <a href="net/java/html/js/package-summary.html">JavaScript</a>;
jaroslav@543
    60
         Get the best of both worlds!
jaroslav@543
    61
         
jaroslav@541
    62
         The goal of these APIs is to use full featured Java runtime 
jaroslav@568
    63
         (like real <a href="http://wiki.apidesign.org/wiki/HotSpot">HotSpot VM</a>), 
jaroslav@541
    64
         but still rely on a very lightweight rendering technology 
jaroslav@541
    65
         (so it can potentially fit 
jaroslav@541
    66
         <a href="http://bck2brwsr.apidesign.org">Bck2Brwsr</a> and definitely
jaroslav@541
    67
         to various types of phones). What can be more lightweight 
jaroslav@541
    68
         (from a browser perspective) than 
jaroslav@541
    69
         <a href="http://wiki.apidesign.org/wiki/HTML">HTML</a>!?
jaroslav@541
    70
         By default we use {@link net.java.html.boot.fx JavaFX's WebView} 
jaroslav@541
    71
         component to display the <a href="http://wiki.apidesign.org/wiki/HTML">HTML</a>. 
jaroslav@541
    72
         We eliminate the need to manipulate the DOM directly, 
jaroslav@541
    73
         there is a special {@link net.java.html.json Java to Knockout.js binding}. 
jaroslav@617
    74
         As a result the <a href="http://knockoutjs.com">HTML uses Knockout.js syntax</a>, 
jaroslav@541
    75
         yet the application code can be written in Java.

        <p>
jtulach@832
    81
            {@link net.java.html.json.Property#array() Array properties} are now
jtulach@832
    82
            mutable from the <a href="http://knockoutjs.com">knockout.js</a>
jtulach@838
    83
            point of view (required {@link org.netbeans.html.json.spi.Proto.Type#replaceValue one SPI change}).
jtulach@834
    84
            The page lookup mechanism can use {@link net.java.html.boot.BrowserBuilder#locale(java.util.Locale) locale}
jtulach@834
    85
            to load localized a page with appropriate suffix.
jtulach@841
    86
            All SPI were moved under the NetBeans namespace - e.g.
jtulach@841
    87
            {@link org.netbeans.html.boot.spi},
jtulach@841
    88
            {@link org.netbeans.html.context.spi},
jtulach@841
    89

jtulach@841
    90
            {@link org.netbeans.html.sound.spi}, and also
jtulach@852
    91
            {@link org.netbeans.html.json.tck}. Methods annotated
jtulach@852
    92
            with {@link net.java.html.js.JavaScriptBody} annotation and
jtulach@852
    93
            without fallback Java code now throw {@link java.lang.IllegalStateException}
jtulach@852
    94
            with a message suggesting to switch to proper
jtulach@852
    95
            {@link net.java.html.BrwsrCtx#execute browser context} to
jtulach@852
    96
            prevent endless debugging when one forgets to do so.

            {@link net.java.html.json.ComputedProperty Derived properties}
jtulach@788
   104
            now deeply check changes in other {@link net.java.html.json.Model model
jtulach@788

            classes} they depend on and recompute their values accordingly.
jtulach@810
   106
            <a target="_blank" href="http://knockoutjs.com">Knockout.js</a> library has been updated

            annotation can be accessed from any thread. {@link org.netbeans.html.sound.spi.AudioEnvironment}
jtulach@747
   115
            can be registered into {@link net.java.html.BrwsrCtx}. There is
jtulach@747
   116
            a {@link net.java.html.json.Models#parse(net.java.html.BrwsrCtx, java.lang.Class, java.io.InputStream, java.util.Collection)  method}
jtulach@747
   117
            to parse a JSON array and convert it into 
jtulach@747
   118
            {@link net.java.html.json.Model model classes}.
jtulach@758
   119
            Improved behavior of <code>enum</code> values in 
jtulach@758
   120
            {@link net.java.html.json.Model knockout bindings}.

   124
            Few bugfixes for better portability. 
jtulach@702
   125
            New API for {@link net.java.html.boot.script.Scripts headless execution}
jtulach@703
   126
            on top of <em>Nashorn</em> - does not run <em>knockout for Java</em>
jtulach@702

            (reported as <a href="https://bugs.openjdk.java.net/browse/JDK-8046013">JDK-8046013</a>),
jtulach@702
   129
            however even in current state it is quite 
jtulach@703

            {@link net.java.html.boot.script.Scripts useful for testing}
jtulach@702

        <p>
jtulach@656
   136
            {@link net.java.html.boot.fx.FXBrowsers} has been extended
jtulach@656
   137
            with new helper methods to make it easier to use HTML+Java
jtulach@656
   138
            API in existing JavaFX applications.
jtulach@656
   139
            The annotation processor is made
jtulach@654
   140
            more robust with respect to errors in callback syntax of
jtulach@654
   141
            {@link net.java.html.js.JavaScriptBody} body parameter.
jtulach@654

            Javadoc of {@link net.java.html.BrwsrCtx#execute} method
jtulach@654
   143
            has been improved based on a failure of its usability study.
jtulach@654
   144
            There can be additional parameters to methods annotated by
jtulach@654
   145
            {@link net.java.html.json.OnReceive} that allows one to
jtulach@654
   146
            pass state when a JSON call is made and use it when it finishes.
jtulach@654
   147
            The mechanism of discovery of sibling HTML page has been
jtulach@654
   148
            extended to work on systems that don't support
jtulach@654

jaroslav@617
   168
            {@link net.java.html.js.JavaScriptBody} annotation has new attribute
jaroslav@617
   169
            {@link net.java.html.js.JavaScriptBody#wait4js()} which allows
jaroslav@617
   170
            asynchronous execution. Libraries using
jaroslav@617
   171
            {@link net.java.html.js.JavaScriptBody} are urged to use this
jaroslav@617
   172
            new attribute as much as possible, as it can speed up execution
jaroslav@617
   173
            in certain environments.

jaroslav@541
   199
jtulach@759
   200
        There are <a href="http://wiki.apidesign.org/wiki/DukeScriptInNetBeans">many ways</a> 
jtulach@759
   201
        to start developing 
jaroslav@541
   202
        <a href="http://html.java.net">Html for Java</a> application. 
jaroslav@541
   203
        However to be sure one chooses the most recent setup, it is recommended
jaroslav@541
   204
        to switch to good old command line and use a 
jaroslav@541
   205
        <a href="http://wiki.apidesign.org/wiki/Knockout4Java">Maven archetype</a>
jaroslav@610
   206
        associated with every version of this project. Make sure at least 
jaroslav@610
   207
        <em>JDK7</em> is your installed Java and type:
jaroslav@541
   208
        <pre>      
jaroslav@541
   209
$ mvn archetype:generate \
jaroslav@541
   210
 -DarchetypeGroupId=org.apidesign.html \
jaroslav@541
   211
 -DarchetypeArtifactId=knockout4j-archetype \
jtulach@759
   212
 -DarchetypeVersion=0.8 <em># or newer version, if available</em>
jaroslav@541
   213
        </pre>
jaroslav@611
   214
        Answer few questions (for example choose myfirstbrwsrpage as artifactId) 
jaroslav@611
   215
        and then you can:
jaroslav@541
   216
        <pre>
jaroslav@541
   217
$ cd myfirstbrwsrpage
jaroslav@541

jaroslav@614

        <p>
jaroslav@614
   246
            This API is part of <a target="_blank"
jaroslav@614
   247
            href="http://netbeans.org">NetBeans.org</a> project and as such
jaroslav@614
   248
            it works naturally with the <a target="_blank"
jaroslav@614
   249
            href="https://netbeans.org/features/index.html">NetBeans IDE</a>.
jaroslav@614
   250
            On the other hand, the API is using nothing NetBeans specific,
jaroslav@614
   251
            it builds on standard Java6 APIs and as such it shall work fine
jaroslav@614
   252
            in any IDE.
jaroslav@614
   253
        </p>
jaroslav@614

jaroslav@614
   255
        <p>
jaroslav@614
   256
            A lot of work is done by 
jaroslav@614
   257
            <a href="http://wiki.apidesign.org/wiki/AnnotationProcessor">
jaroslav@614
   258
            annotation processors</a>
jaroslav@614
   259
            that generate various boiler plate code during compilation. This
jaroslav@614
   260
            is a standard part of Java since JDK6, but for example Eclipse
jaroslav@614
   261
            is known not to deal with processors well and developers using
jaroslav@614
   262
            it need to be careful. IntelliJ users hasn't reported any issues
jaroslav@614
   263
            and of course, NetBeans IDE support for 
jaroslav@614
   264
            <a href="http://wiki.apidesign.org/wiki/AnnotationProcessor">processors</a>
jaroslav@614
   265
            is outstanding.
jaroslav@614

jaroslav@614
   267
        
jaroslav@614
   268
        <p>
jaroslav@614
   269
            When using {@link net.java.html.js.JavaScriptBody} annotation, it is
jaroslav@614
   270
            useful to do a bit of post processing of classes. There is a
jaroslav@614
   271
            <a href="http://wiki.apidesign.org/wiki/Maven">Maven</a> 
jaroslav@614
   272
            plugin for that.
jaroslav@614
   273
            NetBeans IDE will invoke it when doing a build. Other IDEs may 
jaroslav@614
   274
            need some hint to do so. 
jaroslav@614
   275
            Anyway: If one does not see all (generated) sources or is getting
jaroslav@614
   276
            {@link java.lang.LinkageError}s when executing the application, 
jaroslav@614
   277
            switch to command line and do clean build
jaroslav@614
   278
            from there:
jaroslav@614
   279
        </p>
jaroslav@614
   280
        <pre>$ mvn clean install</pre>
jaroslav@614
   281
        <p>
jaroslav@614
   282
            If that succeeds, your IDE of choice will hopefully
jaroslav@614
   283
            pick the generated sources up and present the result of the build 
jaroslav@614
   284
            properly. If not, 
jaroslav@614
   285
            <a href="https://netbeans.org/downloads/">download NetBeans</a>, 
jaroslav@614
   286
            you will be pleasantly

jaroslav@615

        First of all, this is a <em>client technology</em>. You write client applications
jaroslav@615
   307
        with it which may, but need not connect to a server. You don't need
jaroslav@615
   308
        Tomcat or WebLogic to deploy 
jaroslav@615
   309
        <a href="http://html.java.net">HTML for Java</a> applications.

            The sample project generated by

            <code>org.apidesign.html knockout4j-archetype</code> is configured
jaroslav@615
   317

jaroslav@615
   318
            as the rendering technology. This setup is primarily suitable for 
jaroslav@615
   319
            development - it needs no special packaging, starts quickly and
jaroslav@615
   320
            allows you to use classical HotSpot VM debuggers. A final 
jaroslav@615
   321
            artifact from the build is also a ZIP file which you can use
jaroslav@615
   322
            and distribute to your users. Good for desktop applications.
