I just tried it out with Flash Builder. Some issues along the way: 1. I can add it as a .swc dependency in the Build Path settings. Code completion, etc. works great from within FB.
But the FlexJS crosscompiler ExternalTool does not seem to be able to resolve the dependency. This is the error: using FlashBuilder Project Files FlashBuilder settings: -locale en_US -source-path+=C:\p\flexroot\git\flex-asjs\examples\ASJSDOMManipulationExample/src -compiler.accessible=true -output=C:\p\flexroot\git\flex-asjs\examples\ASJSDOMManipulationExample/bin-release/ASJSDOMManipulationExample.swf -library-path+=C:\p\flexroot\git\flex-asjs\examples\ASJSDOMManipulationExample/${SDK_THEMES_DIR}/js/libs/temp/externals/bin/JS.swc -js-output-type=FLEXJS -sdk-js-lib=C:\Program Files\Adobe\Adobe Flash Builder 4.7 (64 Bit)\sdks\FlexJS_0.0.3\js\bin\..\..\frameworks\js\FlexJS\src -fb C:\p\flexroot\git\flex-asjs\examples\ASJSDOMManipulationExample/src/ASJSDOMManipulationExample.mxml command line configuration variable 'compiler.library-path' value contains unknown token 'SDK_THEMES_DIR'. 2. Next step, I copied over the JS.swc file in the project's lib folder. That seemed to work, except that there are no JS equivalents for all the HTML DOM stuff: <snip> using SWC: C:\Program Files\Adobe\Adobe Flash Builder 4.7 (64 Bit)\sdks\FlexJS_0.0.3\frameworks\libs\JQuery.swc using SWC: C:\Program Files\Adobe\Adobe Flash Builder 4.7 (64 Bit)\sdks\FlexJS_0.0.3\frameworks\libs\Mobile.swc using SWC: C:\Program Files\Adobe\Adobe Flash Builder 4.7 (64 Bit)\sdks\FlexJS_0.0.3\frameworks\libs\Network.swc using SWC: C:\p\flexroot\git\flex-asjs\examples\ASJSDOMManipulationExample\libs\JS.swc Could not find file for class: HTMLDivElement File not found: HTMLDivElement java.lang.RuntimeException: Unable to find JavaScript filePath for class: HTMLDivElement at org.apache.flex.compiler.internal.graph.GoogDepsWriter.addDeps(GoogDepsWriter.java:174) at org.apache.flex.compiler.internal.graph.GoogDepsWriter.addDeps(GoogDepsWriter.java:192) at org.apache.flex.compiler.internal.graph.GoogDepsWriter.buildDB(GoogDepsWriter.java:127) at org.apache.flex.compiler.internal.graph.GoogDepsWriter.getListOfFiles(GoogDepsWriter.java:79) at org.apache.flex.compiler.internal.codegen.mxml.flexjs.MXMLFlexJSPublisher.publish(MXMLFlexJSPublisher.java:277) at org.apache.flex.compiler.clients.MXMLJSC.compile(MXMLJSC.java:455) at org.apache.flex.compiler.clients.MXMLJSC._mainNoExit(MXMLJSC.java:319) at org.apache.flex.compiler.clients.MXMLJSC.mainNoExit(MXMLJSC.java:247) at org.apache.flex.compiler.clients.MXMLJSC.staticMainNoExit(MXMLJSC.java:207) at org.apache.flex.compiler.clients.MXMLJSC.main(MXMLJSC.java:156) 3. Then I saw Alex's note about JS.swc working only with a AS only project that simply spits out JS files. The problem with FB is that when I try to do that, the AIR SDK 3.4 is chosen by default. I remove AIR SDK from the newly created project and add only JS.swc as the dependency. Then I created a simple AS3 class: AS: package { public class AS3DOM { public function AS3DOM() { } public function start():void { var div:HTMLDivElement = HTMLDivElement(document.createElement("div")); div.innerHTML = "Hello"; document.body.appendChild(div); } } } JS: <snip> /** * @expose */ AS3DOM.prototype.start = function() { var /** @type {HTMLDivElement} */ div = org_apache_flex_utils_Language.as(document.createElement("div"), HTMLDivElement, true); div.innerHTML = "Hello"; document.body.appendChild(div); }; I created a new FlexJS compile tool that runs jsc.bat on the project. Everything compiled fine and an index.html was spit out. And it renders perfectly fine on the web browser!!! I will create a more comprehensive test and send it out as separate email. Thanks, Om
