I have an e4 RCP product which I want to deliver a e4 RAP application for. Thus, I added a new OSGi bundle which contributes the following implementation of the org.eclipse.rap.rwt.application.ApplicationConfiguration interface, which is declared in the contribution.xml in OSGI-INF folder:
public class BasicApplication implements ApplicationConfiguration {
public void configure(Application application) {
Map<String, String> properties = new HashMap<String, String>();
properties.put(WebClient.PAGE_TITLE, "My RAP Application");
Bundle bundle = FrameworkUtil.getBundle(my.package.E4LifeCycle.class);
String symbolicName = bundle.getSymbolicName();
String appXmiLocation = "platform:/plugin/" + symbolicName + "/Application.e4xmi";
String lifeCycleLocation = "bundleclass://" + symbolicName + "/" + my.package.E4LifeCycle.class.getName();
E4ApplicationConfig applicationConfig = E4ApplicationConfig.create(appXmiLocation, lifeCycleLocation);
E4EntryPointFactory entryPointFactory = new E4EntryPointFactory(applicationConfig);
application.addEntryPoint("/myapp", entryPointFactory, properties);
application.setOperationMode(OperationMode.SWT_COMPATIBILITY);
}
}
Following the example here, I created a new feature bundle including the required plugins and depending on all the required eclipse-related plugins/features (e4, rap, rwt, osgi, ...). It contains this pom.xml:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

In templates/WEB-INF I placed the web.xml and the launch.ini which was generated by the WAR products tool. The web.xml looks like:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN" "http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
<web-app id="WebApp">
<servlet id="bridge">
<servlet-name>equinoxbridgeservlet</servlet-name>
<display-name>Equinox Bridge Servlet</display-name>
<description>Equinox Bridge Servlet</description>
<servlet-class>org.eclipse.equinox.servletbridge.BridgeServlet</servlet-class>
<!-- Framework Controls could be useful for testing purpose, but
we disable it per default -->
<init-param>
<param-name>enableFrameworkControls</param-name>
<param-value>false</param-value>
</init-param>
<!-- Enable multi-language support for the extension registry -->
<!-- the OSGi console is useful for trouble shooting but will fill up your
appserver log quickly, so deactivate on production use. Uncomment
the -console parameter to enabled OSGi console access. -->
<init-param>
<param-name>commandline</param-name>
<param-value>-registryMultiLanguage <!-- -console --></param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>equinoxbridgeservlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
</web-app>
whereas the launch.ini is the following:
# Eclipse Runtime Configuration Overrides
# These properties are loaded prior to starting the framework and can also be used to override System Properties
# @null is a special value used to override and clear the framework's copy of a System Property prior to starting the framework
# "*" can be used together with @null to clear System Properties that match a prefix name.
osgi.*=@null
org.osgi.*=@null
eclipse.*=@null
osgi.parentClassloader=app
osgi.contextClassLoaderParent=app
The build succeeds and a war file is generated. I placed it in the webapps dir of my Tomcat and it is unzipped automatically. But when I point my browser to http: //localhost:8080/my-app-rap I just get a 404. So I assume some configuration of which starting point to use is missing somewhere. Can you help me to figure this out?

Hi Ivan,
I got the example working with your hints. Previously, I tried to access the application just with http://<server_address>:<port>/<WAR_filename_context_path>/. Your advise with the following <entry_point_path> did it. In the example application, one can find the class BasicApplication implementing ApplicationConfiguration which contains this method:
public void configure(Application application) {
Map<String, String> properties = new HashMap<String, String>();
properties.put(WebClient.PAGE_TITLE, "Hello e4 RAP");
application.addEntryPoint("/hello", new E4EntryPointFactory(E4ApplicationConfig.create("platform:/plugin/RapTest/Application.e4xmi")), properties);
application.setOperationMode( OperationMode.SWT_COMPATIBILITY );
}
So, I used "/hello" as the entry point in the URL and got it working. Thank you very much, now I try to fix my specific project and will post the final solution.
cheers
cheers
