Hello!
I try to include an applet in a RAP widget through a qx.ui.embed.Iframe. I am using eclipse-jee-galileo-SR2 with RAP 1.3M5.

I started with the functional GMap demo application as described in the custom widget tutorial (org.eclipse.rap.demo.gmaps from CVS). Then I replaced the complete GMap.js with the following code:

---------8<----------------------------
qx.Class.define( "org.eclipse.rap.gmaps.GMap", {
extend: qx.ui.embed.Iframe,
construct: function( id ) {
this.base( arguments );
this.setHtmlAttribute("id", id);
this._id = id;
this.setSource("http:/"+" /java.sun.com/applets/jdk/1.4/demo/applets/TicTacToe/example 1.html ");
}
});
--------->8----------------------------

This example worked for me with RAP 1.2. But with RAP 1.3 I get the following error:

---------8<----------------------------
Could not evaluate javascript response:
TypeError: this[$1[$4]] is not a function

var req = org.eclipse.swt.Request.getInstance();req.setRequestCounter( "0" );qx.theme.manager.Meta.getInstance().setTheme( org.eclipse.swt.theme.Default );org.eclipse.swt.Request.getInstance().setTimeoutPage( "<html><head><title>Session timed out</title></head><body><p>The server session timed out.</p><p>Please click <a {HREF_URL}>here</a> to restart the session.</p></body></html>" );var wm = org.eclipse.swt.WidgetManager.getInstance();var w = wm.newWidget( "w2", "", false, "org.eclipse.swt.widgets.Shell" );w.addToDocument();w.addState( "rwt_TITLE" );w.setShowMinimize( true );w.setAllowMinimize( true );w.setShowMaximize( true );w.setAllowMaximize( true );w.setShowClose( true );w.setAllowClose( true );w.setResizable( true, true, true, true );w.initialize();w.addEventListener( "changeWidth", org.eclipse.swt.EventUtil.widgetResized );w.addEventListener( "changeHeight", org.eclipse.swt.EventUtil.widgetResized );w.addEventListener( "changeLeft", org.eclipse.swt.EventUtil.widgetMoved );w.addEventListener( "changeTop", org.eclipse.swt.EventUtil.widgetMoved );w.setSpace( 0, 300, 0, 300 );w.setTabIndex( -1 );w.setVisibility( true );w.setCaption( "GMaps Demo" );w.open();w.setActive( true );w.setMinWidth( 80 );w.setMinHeight( 23 );var w = wm.newWidget( "w3", "w2", true, "org.eclipse.rap.gmaps.GMap", '"w3"' );w.setAppearance( "composite" );w.setOverflow( "hidden" );w.setSpace( 0, 296, 19, 277 );w.setZIndex( 300 );w.setTabIndex( 1 );w.setAddress( "" );var w = wm.findWidgetById( "w2" );w.setActiveControl( wm.findWidgetById( "w3" ) );org.eclipse.swt.WidgetManager.getInstance().focus( "w3" );
----------->8----------------------------

I found a sort of solution to this problem at https://bugs.eclipse.org/bugs/show_bug.cgi?id=261355#c11, but it does not quite work for me. I added the dummy properties, so that the GMap.js is now:

---------8<----------------------------
qx.Class.define( "org.eclipse.rap.gmaps.GMap", {
extend: qx.ui.embed.Iframe,
properties : {
// Dummy property to make it works with RAP 1.3
backgroundGradient : {
check : "Array",
nullable : true,
init : null,
themeable : true
}
},
construct: function( id ) {
this.base( arguments );
this.setHtmlAttribute("id", id);
this._id = id;
this.setSource("http:/"+" /java.sun.com/applets/jdk/1.4/demo/applets/TicTacToe/example 1.html ");
}
});
--------->8----------------------------

But now I get a different error:

---------8<----------------------------
Could not evaluate javascript response:
TypeError: w.setAddress is not a function

var req = org.eclipse.swt.Request.getInstance();req.setRequestCounter( "0" );qx.theme.manager.Meta.getInstance().setTheme( org.eclipse.swt.theme.Default );org.eclipse.swt.Request.getInstance().setTimeoutPage( "<html><head><title>Session timed out</title></head><body><p>The server session timed out.</p><p>Please click <a {HREF_URL}>here</a> to restart the session.</p></body></html>" );var wm = org.eclipse.swt.WidgetManager.getInstance();var w = wm.newWidget( "w2", "", false, "org.eclipse.swt.widgets.Shell" );w.addToDocument();w.addState( "rwt_TITLE" );w.setShowMinimize( true );w.setAllowMinimize( true );w.setShowMaximize( true );w.setAllowMaximize( true );w.setShowClose( true );w.setAllowClose( true );w.setResizable( true, true, true, true );w.initialize();w.addEventListener( "changeWidth", org.eclipse.swt.EventUtil.widgetResized );w.addEventListener( "changeHeight", org.eclipse.swt.EventUtil.widgetResized );w.addEventListener( "changeLeft", org.eclipse.swt.EventUtil.widgetMoved );w.addEventListener( "changeTop", org.eclipse.swt.EventUtil.widgetMoved );w.setSpace( 0, 300, 0, 300 );w.setTabIndex( -1 );w.setVisibility( true );w.setCaption( "GMaps Demo" );w.open();w.setActive( true );w.setMinWidth( 80 );w.setMinHeight( 23 );var w = wm.newWidget( "w3", "w2", true, "org.eclipse.rap.gmaps.GMap", '"w3"' );w.setAppearance( "composite" );w.setOverflow( "hidden" );w.setSpace( 0, 296, 19, 277 );w.setZIndex( 300 );w.setTabIndex( 1 );w.setAddress( "" );var w = wm.findWidgetById( "w2" );w.setActiveControl( wm.findWidgetById( "w3" ) );org.eclipse.swt.WidgetManager.getInstance().focus( "w3" );
--------->8----------------------------

Where does the call to w.setAddress come from? I have removed the call to 'map.setAddress( "Stephanienstra├če 20, Karlsruhe" );' from the GMapDemo class in the custom widget help text.
And how can I correct the example above to display an applet in the Iframe?

Thanks
Robbi

Hi Robbi,

take a look at GMapLCA#renderChanges method and remove this line:
writer.set( PROP_ADDRESS, JS_PROP_ADDRESS, gmap.getAddress() );

Best,
Ivan

Hrmpf, I removed the getAddress call as you suggested.

This causes a reproducible crash of the whole eclipse IDE. On the terminal, which started eclipse, I see:

java: ../../../../src/plugin/share/plugin2/common/LocalFramePusher .h:25: LocalFramePusher::LocalFramePusher(int): Assertion `env != __null' failed.

Any idea?

Before the crash I see jetty logging its start in the eclipse console as usual without error messages. Then the blue gradient RAP background and the GMap shell appear in the browser, and half a second later all is destroyed.

Thanks for the tip, nevertheless it brings me closer to a solution, I hope.

Update:

If I run the RAP application in an external browser instead of the eclipse internal browser, the applet works fine. Thanks again!

Because I find it more convenient to use the internal browser for testing, any hint about how to avoid the crash is highly appreciated.

Hi Robbi,

there are a couple of SWT bugs describing problems with applets in the
SWT browser. You might want to search the Eclipse bugzilla if your issue
is already known and if not open a new bug against Platform/SWT.

Regards, Ralf
