Eclipse Virgo をアプリケーション サーバーとして使用して、restlet をアプリケーションに統合しようとしています。Virgo は OSGi に基づいているorg.restlet.osgiため、最新の Virgo リリースは Java 1.7 に依存するバンドルについて不平を言うため、Java 1.7 に依存しないライブラリと最新バージョン (restlet 2.2.3) を使用する必要がありました。
REST API を配信するために Eclipse Virgo Web サーバーを使用するように restlet を取得しようとしましたが、何を試してもうまくいかないようです。もちろん、Eclipse Virgo とは別のポートで restlet 独自の Web サーバーを起動することはできますが、その Web サーバーを使用して成功することはありませんでした。それはまったく可能ですか？
アップデート
スプリングもストーリーに絡むので、もっと面白くなると思います。Spring 関連の構成は以下のとおりです。
<context-param>
<param-name>contextClass</param-name>
<param-value>org.eclipse.virgo.web.dm.ServerOsgiBundleXmlWebApplicationContext</param-value>
</context-param>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>springdispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextClass</param-name>
<param-value>org.eclipse.virgo.web.dm.ServerOsgiBundleXmlWebApplicationContext</param-value>
</init-param>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/*.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springdispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
私は今、この例外を受けています:
