How to build and deploy war file of e4 RAP applica

Question

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:

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>

  </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?

Answer 1

Try to change the address you're trying to access to: http: //localhost:8080/<.war file.>//myapp
