在Apache ServiceMix中運行Kafka使用者

Question

我正在嘗試使用camel-kafka創建一個包，並在servicemix中運行它。該模塊是一個非常基本的卡夫卡消費者，它使用駱駝卡夫卡連接器，並從卡夫卡主題消費消息。我能夠使用MVN駱駝成功運行模塊：運行，但在安裝服務組合內的同一模塊作爲一個OSGi包給出以下錯誤：

UPDATE

上面的警告得到了安裝駝後解決-kafka功能在servicemix中。 （感謝Achim）然而，然後我就開始收到以下錯誤：安裝由maven庫下載0.4和0.3 jar文件：

我使用OSGi安裝zkclient。但是，此模塊的名稱空間爲com.101tec，而錯誤指向org.101tec。我不知道如何在這裏繼續。任何指針都會非常有幫助。

Answer 1

這兩種錯誤都做了

1. 功能可以解決問題：安裝駱駝卡夫卡

2. 通過從https://github.com/sgroschupf/zkclient安裝zkclient jar文件。
