Question

wso2 ESBを使用してローカルディレクトリからファイルを選択し、そのファイルのレコードをデータベースに挿入して電子メールを送信しようとしています。

はhttps://docs.wso2.com/display/ESB490/Sample+271%3A+File+Processing

以下

に与えられた手順に従っSmooksの-configファイルである

<smooks-resource-list xmlns="http://www.milyn.org/xsd/smooks-1.0.xsd"> 

<!--Configure the CSVParser to parse the message into a stream of SAX events. --> 
<resource-config selector="org.xml.sax.driver"> 
<resource>org.milyn.csv.CSVParser</resource> 
<param name="fields" type="string-list">name,surname,phone</param> 
</resource-config>       
</smooks-resource-list> 

これは、ESBサーバーに

を解決するために私を助けてください

Answer 1

どういうわけかESBはクラスを見つけることができません。 milyn-smooks-csv-1.2.4.jarが "ESB_HOME"/repository/components/libにあることを確認してください。

Answer 2

新しいバージョンmilyn-smooks-all-1.5.1 jarにはCSVParserがないため、smooks-configファイルのCSVParserをCSVReaderに変更すると問題が解決しました。
