Camel ルートを OSGI(Equinox)-Bundle またはプラグイン プロジェクト内で動作させるのに問題があります。
ルートは次のようになります。
public class Example2Routes extends RouteBuilder {
@Override
public void configure() throws Exception {
this.from("cxf:http://localhost:8080/exampleWS?wsdlURL=META-INF/exampleWS.wsdl&dataFormat=PAYLOAD").to("stream:out");
}
}
Camelコンテキストを開始する必要がある私のテストクラス:
public class Test {
public static void run() throws Exception {
DefaultCamelContext camelContext = new DefaultCamelContext();
camelContext.addRoutes(new Example2Routes());
camelContext.start();
}
}
バンドルは、OSGI フレームワークの実行構成を使用して Eclipse 内で開始されます。

しかし、今、CamelContext を「開始」する方法は? osgi がなくても、標準の Java アプリケーションとして、この例は機能しました。しかし、そこにはキャメルコンテキストを含むメインメソッドがありました。
Activator を使ってラクダのコンテキストを開始しようとしました:
public class Activator implements BundleActivator {
@Override
public void start(BundleContext arg0) throws Exception {
Test.run();
}
}
しかし、これにより次のようなエラーが発生しました
Failed to resolve endpoint: cxf://http://localhost:8081/exampleWS?dataFormat=PAYLOAD&wsdlURL=META-INF%2FexampleWS.wsdl due to: No component found with scheme: cxf
コンソールは言うが：

Activator の Test.run() の問題は、必要なすべてのバンドル/コンポーネントが開始される前に run メソッドが呼び出されるために発生するのでしょうか? しかし、そうでなければキャメルコンテキストを開始する方法は?
更新 1
OsgiDefaultCamelContext に変更されました。いくつかのインポートを行いました。今私は得ています：
The bundle "org.apache.httpcomponents.httpclient_4.2.0 [119]" could not be resolved. Reason: Missing Constraint: Import-Package: org.apache.http; version="4.2.0"
&
The bundle "CamelOSGIExample_1.0.0.qualifier [120]" could not be resolved. Reason: Missing Constraint: Import-Package: org.apache.http.nio.conn; version="4.0.0.beta3"
しかし、このバンドルが見つかりません..
更新 2:
の原因
java.lang.ClassNotFoundException: org.apache.http.nio.conn.ClientAsyncConnectionManager
httpasyncclient-osgi-4.0-beta3.jarをダウンロードし、インポートにorg.apache.http.nio.connを追加しました。
その後、以前のバンドルにはorg.apache.http.clientやorg.apache.http.authなどを必要とするという問題が発生しました。そこで、必要なクラスを含むhttpclient-osgi-4.2.1.jarとhttpclient-osgi- 4.2.2.jar をダウンロードしました (バージョン 4.2.1 と 4.2.2 で必要なインポートがあったため)。しかし、このバンドルをランチ構成に追加したにもかかわらず、私は得る
org.osgi.framework.BundleException: Exception in siServer.Activator.start() of bundle CamleOSGIExample.

インポートにorg.apache.http.nio.connを追加したため、この例外がわかりません。
org.apache.http.nio.connを必要とするバンドルを検索し、cxf-2.7.3.jar を見つけました。しかし、camel の cfx-component を使用するには、このバンドルも必要だと思います..
