I think that some people in this community are interested by a GWT/Sling integration. There is an example in the Sling source but there are some lacks in term of integration and RAD dev. My main goal is to provide a good dev environment to build quickly gwt applications for Sling and to avoid manual configuration. I don't want to build a bundle package to just test my gwt application. During my dev phase, I want to run it from eclipse or from a mvn command line. So, here some information on that topic : It is possible to run in hosted mode a GWT application within Sling with the option "noserver". You have to follow the instructions described in [1]. I'm using the maven gwt plugin [2] and it works fine on my machine. You have to setup the "noserver" mode in the pom.xml (see below a pom.xml sample file). I have to clean up the pom but the current file will give you some ideas on how to configure a new gwt application for Sling. Until now, there is only one issue when running Gwt in hosted mode with Sling. Indeed, following the document [1], you have to setup a new sling folder that will contains the minim gwt application files. Rigth now, I'm doing it manually but it could be done with a new mojo in the Sling maven plugin. Are you agree if I'm creating a new mojo for the gwt/sling integration ?
My work is not yet finished but if there are some interests, I can create a new jira issue for this gwt integration and modify the current gwt demo. br, Christophe [1] http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5&s=google-web-toolkit-doc-1-5&t=FAQ_HostedModeNoServer , http://www.screaming-penguin.com/node/4500 [2] http://gwt-maven.blogspot.com/ Pom.xml with maven gwt plugin. ----------------------------------------------- <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0"; xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd";> <modelVersion>4.0.0</modelVersion> <groupId>org.apache.sling.browser</groupId> <artifactId>org.apache.sling.browser</artifactId> <version>2.0.0-incubator-SNAPSHOT</version> <packaging>bundle</packaging> <name>Apache Sling Browser</name> <description> This bundle provides the Sling browser.
