我試圖運行在Ubuntu 11.04 64位的Apache Synapse示例，我發現問題樣品NR評估XPath表達式2問題的計算XPath，而使用Apache突觸
我的XPath表達式：
$ <soapenv:Body><m0:getQuote xmlns:m0="http://services.samples"><m0:request><m0:symbol>IBM</m0:symbol></m0:request></m0:getQuote></soapenv:Body></soapenv:Envelope>
和R：
$ <definitions xmlns="http://ws.apache.org/ns/synapse"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://ws.apache.org/ns/synapse http://synapse.apache.org/ns/2010/04/configuration/synapse_config.xsd">
<sequence name="main">
<switch source="//m0:getQuote/m0:request/m0:symbol" xmlns:m0="http://services.samples">
<case regex="IBM">
<!-- the property mediator sets a local property on the *current* message -->
<property name="symbol" value="Great stock - IBM"/>
</case>
<case regex="MSFT">
<property name="symbol" value="Are you sure? - MSFT"/>
</case>
<default>
<!-- it is possible to assign the result of an XPath expression as well -->
<property name="symbol" expression="fn:concat('Normal Stock - ', //m0:getQuote/m0:request/m0:symbol)"/>
</default>
</switch>
<log level="custom">
<!-- the get-property() XPath extension function allows the lookup of local message properties
as well as properties from the Axis2 or Transport contexts (i.e. transport headers) -->
<property name="symbol" expression="get-property('symbol')"/>
<!-- the get-property() function supports the implicit message headers To/From/Action/FaultTo/ReplyTo -->
<property name="epr" expression="get-property('To')"/>
</log>
<!-- Send the messages where they are destined to (i.e. the 'To' EPR of the message) -->
<send/>
</sequence>
它是以下數據運行esult是：
2011-08-08 15：37：04227 [ - ] [HttpClientWorker-1] DEBUG SwitchMediator的XPath：// M0：爲getQuote/M0：請求/ M0：符號的計算結果爲：
2011 -08-08 15：37：04227 [ - ] [HttpClientWorker-1]開關的情況下DEBUG SwitchMediator無匹配 - 執行默認
，而應該去：
$<case regex="IBM">
<!-- the property mediator sets a local property on the *current* message -->
<property name="symbol" value="Great stock - IBM"/>
</case>
有誰知道什麼都可以是問題嗎？我幾天前安裝了Ubuntu，所以有可能，那個系統上缺少一些東西。
