SpringとCastorのO/Xマッパーについて知識のある方助けてください。

Last updated at Posted at 2012-05-19

下記のサイトでSpringとCastorでO/Xマッパーについて勉強しました。

しかし、上記のサイトのソースをダウンロードし、足りないjarを揃えてやってみましたが、
エラーが出てきてなかなかうまく動くことができませんでした。

  • 揃えたファイルの一式は下記の所でダウンロードできます。
    http://dl.dropbox.com/u/25436822/Spring_Castor/OXMTest.zip

  • 自分が色々試して見た結果、下記のxmlファイルの
    <property name="mappingLocation" value="classpath:mapping.xml" />
    の部分のmapping.xmlファイルがオブジェクト生成時にパスの指定の問題でPGが探せなかったことと考えています。ここまで見てもし何か分かったら、教えてください。ちなみに、絶対パスで設定してみたこともあります。
    <property name="mappingLocation" value="C:\\workspace\\OXMTest\\bin\\mapping.xml" />
