Android上的Knopflerfish上的Pax Web

我打算在Android上使用Web服務啓動OSGi，其中我將能夠在Android Browser上運行Java Server Pages（jsp）和Java Servlets。Android上的Knopflerfish上的Pax Web

我的第一步是在Android上安裝Knopflerfish。我遵循這個來自knopflerfish的教程：http://www.knopflerfish.org/releases/5.0.0/docs/android_dalvik_tutorial.html

Knopflerfish做得很好，我在Android手機的瀏覽器上看到了localhost：8080。

我的第二步是在Knopflerfish上安裝Pax Web，它也安裝在Android上。我也跟着從這裏其教程：http://www.knopflerfish.org/kf_pax_web_tutorial.html

教程表示：

卸載KF HTTP束

的第一步是停止HTTP根束和卸載JSDK和HTTP作爲PaxWeb的服務器軟件包將接管此功能。通常情況下，您很可能還想卸載HTTP根套裝，但對於本教程，我們將安裝它。在進入下一步之前，請確保執行刷新包。

然後：

安裝PaxWeb

第二步是安裝並從PaxWeb啓動以下束。

  • PAX-web的JSP的1.0.2.jar（安裝）
  • PAX-web的碼頭束-1.0.2.jar（安裝&開始）
  • PAX-web的extender-戰爭0.8.0.jar（安裝&開始）

的Pax Web包已成功安裝。

問題

的Pax Web束不能啓動。

當我嘗試啓動HTTP-root-IMP Knopflerfish包時，它在控制檯上顯示此錯誤消息。

[stderr] ## DEBUG: errors - FrameworkErrorEvent bundle #20 
[stderr] ## DEBUG: errors - FrameworkErrorEvent throwable:

     at java.lang.Thread.run(Thread.java:856)

另一個是當我會從Knopflerfish的Pax Web教程啓動束。在這裏，我試圖啓動pax-web-jetty-bundle-1.0.2.jar (OPS4J Pax Web - Jetty Bundle)：

[stderr] ## DEBUG: errors - FrameworkErrorEvent bundle #16 
[stderr] ## DEBUG: errors - FrameworkErrorEvent throwable:

     at org.knopflerfish.bundle.console.Command.run(Command.java:226) 
     at java.lang.Thread.run(Thread.java:856)

最後，當我嘗試運行pax-web-extender-war-0.8.0.jar (OPS4J Pax Web - Extender - War)此錯誤信息也將出現：

[stderr] ## DEBUG: errors - FrameworkErrorEvent bundle #17 
[stderr] ## DEBUG: errors - FrameworkErrorEvent throwable:

     at java.lang.Thread.run(Thread.java:856)

我也試着開始pax-web-jsp-1.0.2.jar (OPS4J Pax Web - Jsp Support)這個錯誤消息顯示：

[stderr] ## DEBUG: errors - FrameworkErrorEvent bundle #15 
[stderr] ## DEBUG: errors - FrameworkErrorEvent throwable:

從我從錯誤信息中瞭解到的情況，這些軟件包正在尋找這些軟件包。有什麼辦法可以解決這個問題，並且能夠在OSGi框架上成功運行Android上的Java Web應用程序？

首先，我強烈建議對所有Pax-Web捆綁包使用相同的版本，其次你缺少一個servlet API捆綁包。此外，它看起來像你還缺少一些其他Pax-Web捆綁包。你最有可能需要以下包：

  • PAX-Web的API
  • PAX-Web的碼頭束
  • PAX-Web的JSP
  • PAX-網絡運行
  • PAX-Web的SPI

，如果你想用戰爭則需要在

  • PAX-Web的擴展，戰爭
  • PAX-URL戰
  • 和一對夫婦更多...

大同的Web的最新版本是3.0.2，所以你應該小心選擇取決於在你想要做什麼。您可能會發現檢查Pax-Web的ITests（取決於您要使用的版本）以獲取需要哪些捆綁軟件的靈感很有幫助。 我建議以最低設置開始。這樣你首先從http服務開始，並根據你的需求進行增強。

查看Pax-Web project at Github，特別是樣本和itests模塊以獲取更多詳細信息。

我已經在這裏成功下載了pax-web jar文件：http://repo1.maven.org/maven2/org/ops4j/pax/web/。但是，在我正在執行的當前項目中添加這些jar的步驟之一是將其「dexify」，但我無法創建'pax-web-jetty-bundle-3.0.2.jar'的dex文件。在將它們包含到當前項目之前，我需要一個jar文件的dex文件。 –

你能推薦什麼servlet API包？ @Achim –

您可以在https://github.com/ops4j/org.ops4j.pax.web/blob/master/pax-web-features/src/main找到karaf功能文件（需要的軟件包列表） /resources/features.xml#L4，這會讓你更進一步，我希望。 –
