Question

我正在尝试将ActiveMQ persitenceAdapter设置为Oracle 11g（11.2）数据库。通过Tanuki包装器启动ActiveMQ时，我得到的是无法加载JDBC驱动程序类'oracle.jdbc.driver.OracleDriver'的异常。我在网上搜索了几个小时而没有找到任何相关的答案。我的类路径是正确的。

我觉得Tanuki包装器没有考虑我的类路径定制。

如果您发现任何错误或为我提供了一个有效的例子，请告诉我

我的设置是：
activemq.xml中

<broker xmlns="http://activemq.apache.org/schema/core" brokerName="test1" dataDirectory="/path/to/existing">
    ...
    <persistenceAdapter>
        <jdbcPersistenceAdapter dataDirectory="/path/to/existing/activemq-data" dataSource="#oracle-ds"/>
    </persistenceAdapter>
    ...
</broker>

<bean id="oracle-ds" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
    <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/>
    <property name="url" value=" jdbc:oracle:thin:@db.domain:1521:DEV01 "/>
    <property name="username" value="username"/>
    <property name="password" value="password"/>
    <property name="poolPreparedStatements" value="true"/>
</bean>

<import resource="jetty.xml"/>

wrapper.conf

wrapper.java.classpath.1=%ACTIVEMQ_HOME%/bin/wrapper.jar
wrapper.java.classpath.2=%ACTIVEMQ_HOME%/bin/activemq.jar
wrapper.java.classpath.3=%ACTIVEMQ_HOME%/lib/*

Answer 1

我正在回答我自己的问题：

正如Alexey Odintsov指出的那样，我犯了一个错字要解决此问题，请在activemq.xml文件中更改行

<property name="url" value=" jdbc:oracle:thin:@db.domain:1521:DEV01 "/>

删除值引号

中的前导和尾随空格

<property name="url" value="jdbc:oracle:thin:@db.domain:1521:DEV01"/>
