API バンドルを作る †

  1. [新規]-[Maven]-[OSGiバンドル]
    api1.png
  2. 作成場所を OSGiExam? の直下にする
    api2.png
  3. 自動的に OSGiExamApi? は、OSGiExam? のモジュールになった
    api3.png
    OSGiExam?/pom.xml には、配下のモジュール定義が追加されている 
        </repositories>  
  <modules>
    <module>OSGiExamApi</module>
  </modules>
</project>
  4. OSGiExam?/OSGiExamApi?/pom.xml を編集して、親プロジェクト (OSGiExam?) の pom.xml のライブラリ参照定義を継承する。(GUI からやりたければ、ソースツリーの [依存性] を右クリックして、[依存性の追加]-[依存性管理] で、親プロジェクトの管理しているライブラリを追加できる)

  6. インタフェースを作成 (EJB用) 
    package com.mycompany.osgiexamapi;

import javax.ejb.Local;

@Local
public interface GoodBye {
    String sayGoodBye(String name);
}
  7. ほかのバンドルから参照できる、このバンドルの公開パッケージの設定。(GUI からやりたければ、ソースツリーの [OSGiExamApi?] を右クリックして、[プロパティ]-[パッケージをエクスポート] で、親プロジェクトの管理しているライブラリを追加できる)

                </configuration>
            </plugin>
        </plugins>
    </build>
  8. [実行]-[ビルド] で、バンドルができる。バンドルと言っても、普通の Jar。MANIFEST.MF ファイルに追加の記述があるだけ。MANIFEST.MF は、pom.xml に定義された maven-bundle-plugin がビルド時に作成する。

テスト用の Web アプリを作る †

  1. プロジェクトを作成
    web1.png
    /OSGiExam? 配下にモジュールとして Web アプリを作る (OSGiExam?/OSGiExamWeb? に作成)
  2. 依存ライブラリの設定 (親プロジェクト (OSGiExam?) と APIを参照する)

    ...
  3. WEB-INF/beans.xml を作成 (中身は空で良い)。CDIを使うために必要

POJO OSGi バンドルを作る †

  1. [新規]-[Maven]-[OSGiバンドル]
  2. /OSGiExam? 配下にモジュールとして OSGi Bundle アプリを作る (OSGiExam?/OSGiExamImpl? に作成)
  3. OSGiExam?/OSGiImpl?/pom.xml を編集して、親プロジェクト (OSGiExam?) の pom.xml のライブラリ参照定義を継承する。(GUI からやりたければ、ソースツリーの [依存性] を右クリックして、[依存性の追加]-[依存性管理] で、親プロジェクトの管理しているライブラリを追加できる) 
    <?xml version="1.0" encoding="UTF-8"?>

  4. OSGiExamAPI にある Hello インタフェースの実装をする 
    package com.mycompany.osgiexamimpl;

import com.mycompany.osgiexamapi.Hello;

public class HelloImpl implements Hello {

    @Override
    public String sayHello(String name) {
        return "Hello " + name;
    }    
}
  5. Activator#start で、HelloImpl? を BundleContext? に追加する 
    package com.mycompany.osgiexamimpl;

import com.mycompany.osgiexamapi.Hello;
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;

public class Activator implements BundleActivator {

    @Override
    public void start(final BundleContext context) throws Exception {
        System.out.println(String.format("start::%s", Activator.class.getCanonicalName()));
        context.registerService(Hello.class.getName(), new HelloImpl(), null);
        System.out.println(String.format("activated::%s as %s", HelloImpl.class.getName(), Hello.class.getName()));
    }

    @Override
    public void stop(final BundleContext context) throws Exception {
        context.ungetService(context.getServiceReference(Hello.class.getName()));
        System.out.println(String.format("deactivated::%s", Hello.class.getName()));
        System.out.println(String.format("stop::%s", Activator.class.getCanonicalName()));
    }
}
    バンドル初期化時には、まだ他のバンドルを参照できないことに注意。Logger も使えないよ (ハマった)、なにか出力したかったら System.out.prinltn() で

動かしてみる

  1. OSGiExamWeb? に、LookupPojoFromCDI を作って、HelloImpl? が CDI で injection できるか試してみる 
    package com.mycompany.osgiexamweb;

import com.mycompany.osgiexamapi.Hello;
import java.io.IOException;
import java.io.PrintWriter;
import javax.annotation.Resource;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@WebServlet(name = "LookupPojoFromCDI", urlPatterns = {"/LookupPojoFromCDI"})
public class LookupPojoFromCDI extends HttpServlet {

    @Resource
    private Hello hello;
        
    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        try {
            out.println("<!DOCTYPE html>");
            out.println("<html>");
            out.println("<head>");
            out.println("<title>@Resource</title>");            
            out.println("</head>");
            out.println("<body>");
            out.println("<h1>lookup POJO by @Resource</h1>");
            out.println(hello.sayHello("Sachi"));
            out.println("<br/><br/><font color=\"gray\">Hello Class is ");
            out.println(hello.getClass().getCanonicalName());
            out.println("@");
            out.println(hello.hashCode());
            out.println("</font>");
        } catch (Exception ex) {
            out.println("<pre>");
            ex.printStackTrace(out);
            out.println("</pre>");
        } finally {
            out.println("</body>");
            out.println("</html>");
            out.close();
        }
    }
}
  2. ビルド OSGiExam? で、[実行]-[消去してビルド]

    }
}
