servicemix 4.3.2駱駝cxf生產者到cxf-nmr消費者不工作

我一直在試圖讓兩個單獨的包通過使用駱駝cxf生產者的nmr端點進行通信。我整個星期都在研究這個問題，到目前爲止我無法完成這項工作。servicemix 4.3.2駱駝cxf生產者到cxf-nmr消費者不工作

但是我可以像所有示例cxf-camel-nmr中的nmr端點一樣沒有問題，所以我知道這個bundle是可以的。說真的，這是一個超級簡單的Hello World世界原型，我無法得到它的工作。

任何幫助或建議將是真棒！

ENV：爪哇1.5 的Apache ServiceMix的4.3.2（處女安裝）

在ServiceMix的我有兩個單獨的OSGi包。我無法讓我的駱駝cxf生產者成功調用nmr端點，並且無法解決如何解決問題。

看起來我過去兩天一直在處理完全相同的問題。我相信我現在已經解決了它。以下是我發現的：

StaxUtils中的NPE似乎歸因於source（javax.xml.transform.Source）是null。當exchange.getIn().getBody(Source.class)在NMRDestination類中返回null時，它可以是null。這是事情變得有點醜陋的地方。讓我們退後一步。

要查看您的消息是否有身體，當它進入您的身體時，您需要打開TRACE日誌級別。您可以使用log:set TRACE命令在servicemix控制檯中執行此操作。 ExchangeUtils#display(Exchange)只有在TRACE中打印出正文才能調用，即使在DEBUG中也是如此。有了TRACE，你就會看到諸如此類的東西：

id:  1520804564-51998-1331328769981-0-3 
    mep:  InOut 
    status: Active 
    role:  Consumer 
    target: ... 
    properties: [ ] 
    In: [ 
     content: 
     ]

In.content部分本質上是消息的正文。我相信你們的交流有着和我一樣的身體。這意味着它在NMR/Camel路由模式中的某個地方「丟失」了。

exchange.getIn().getBody(Source.class)經過一個特殊的轉換邏輯，如果某些東西沒有點擊，它可能會默默地（！）返回null。看看org.apache.camel.impl.converter.BaseTypeConverterRegistry#doConvertTo()。

當我在閱讀TRACE日誌時，我注意到另一個關於org.apache.xml.serializer.ToXMLStream的微妙（幾乎是FYI）跟蹤消息對我的軟件包不可見。我認爲NMR沒有將消息轉換爲Source對象，並且沒有告訴我任何關於它的信息。

SOLUTION：我最終加入org.apache.xml.serializer我Import-Package行家指令與org.apache.xalan沿（一旦我添加了串行輸入的是炸燬了，接下來的事情就是ClassNotFountException抱怨org.apache.xalan.xsltc.trax.DOM2SAX）。一切都在運行時間，全都在lib/endorsed之前，直到現在，我的服務包才發現它。

它現在可以工作，我的信息在目標端點。還有一點需要注意的是駱駝內容的streamCache屬性。在最新版本的Camel中沒有默認緩存流資源，並且除非緩存，否則您的代碼將無法從流中多次讀取。

現在仍然存在的問題是爲什麼我必須讓服務「意識到」這些依賴關係NMR /駱駝需要沿着路線發送我的消息。沒有任何意義。
