问题
I am trying to setup ActiveMQ persitenceAdapter to an Oracle 11g (11.2) database. When starting ActiveMQ through the Tanuki wrapper I am getting the Cannot load JDBC driver class 'oracle.jdbc.driver.OracleDriver' exception. I am searching the net for hours without finding any relevant answer. My classpath is correct.
I have the feeling that the Tanuki wrapper is not taking my classpath customization into account.
Could you please tell me if you see anything wrong or provide me with a working example
My settings are:
activemq.xml
<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"/>

I am answering my own question:
As pointed by Alexey Odintsov I made a typo.
To fix the issue, in the activemq.xml file change the line
<property name="url" value=" jdbc:oracle:thin:@db.domain:1521:DEV01 "/>
by removing the leading and trailing space within the value quotes
<property name="url" value="jdbc:oracle:thin:@db.domain:1521:DEV01"/>
