昨日からこのエラーが出て、頭に浮かんだことをすべて試したり、インターネットで検索したりしても、解決できません。コンテキスト: Java 6、Spring 3.1.4、camel 2.11.1、Oracle ドライバー 10.2.0.2。
私はキャメルコンテキストファイルにこのBeanを持っています:
<bean id="myDataSource" class="**org.springframework.jdbc.datasource.DriverManagerDataSource**">
<property name="driverClassName" value="**oracle.jdbc.driver.OracleDriver"**/>
<property name="url" value="jdbc:...."/>
<property name="username" value="userhere"/>
<property name="password" value="passwordhere"/>
</bean>
また、Bean のこのクラスを試しました: class=" org.apache.commons.dbcp.BasicDataSource " そして、この Bean を使用する別の場所の Bean。私はこれをPOMに持っています（ちなみに、この依存関係は同じデータベースを指す別のプロジェクトから持ってきたので、正しいバージョンです）：
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc14</artifactId>
<version>10.2.0.2</version>
<scope>provided</scope>
</dependency>
私はそれを機能させようとした別のことのために、これも持っています:
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-jdbc</artifactId>
<version>2.11.1</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>3.1.4.RELEASE</version>
</dependency>
<dependency>
<groupId>commons-dbcp</groupId>
<artifactId>commons-dbcp</artifactId>
<version>1.4</version>
</dependency>
- 接続データ(url、ユーザー、およびパスワード)、それは検証済みであり、接続しようとした環境のデータベースのそれぞれについて正しいです。
- Maven の依存関係に ojdbc14 jar が表示されます。また、デバッグ出力を有効にして「maven run」を実行すると表示されます: [DEBUG] プロジェクトの依存関係アーティファクトの追加: ojdbc14 to classpath
- jar 内にクラスoracle.jdbc.driver.OracleDriverが表示されます。
それでも、毎回これらのエラーが発生します：
class="org.apache.commons.dbcp.BasicDataSource" を dataSource クラスとして使用する場合: class="org.apache.commons.dbcp.BasicDataSource"

現在、Eclipseでmavenプラグインを使用して実行していますが、念のためですが、Mavenで実行する場合は解決策ではないことを知って、ojdbc jarをEclipseクラスパスに追加してみました。しかし、何も機能しませんでした。オラクル ドライバーのバージョンは Orcale に対して正しく、URL は正しいため、ユーザーとパスワードは、アクセスできる環境データベース (ローカル、開発、QA、ステージング) のそれぞれを指すようにしました。何も機能しませんでした。
実際にjarをクラスパスに追加しているときに、OracleDriverを見つけたりロードしたりできない理由は誰にもわかりますか?
