I was working on the AnyPoint Studio with Mule 3.5 Community Runtime, while trying to connec to my oracle db it is throwing the following error at runtime

I have used Generic DB connection The following is the DB config

<spring:beans>
    <spring:bean id="jdbcDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" name="jdbcDataSource">
        <spring:property name="url" value="jdbc:oracle:thin:@10.211.55.8:1521:mosaic"/>
        <spring:property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/>
        <spring:property name="username" value="fw"/>
        <spring:property name="password" value="fw"/>
    </spring:bean>
</spring:beans>
<db:generic-config name="Mosaic_Database_Configuration" dataSource-ref="jdbcDataSource" doc:name="Generic Database Configuration"/>

回答1:

You need to have the ojdbc.jar included in your Classpath. There is a good tutorial provided here that details how to do this.

Alternatively, if you already have the jar in your classpath, I'd suggest trying a different spring bean. I've used the following to connect to an Oracle database previously:

<spring:bean id="dataSource" class="org.enhydra.jdbc.standard.StandardDataSource" destroy-method="shutdown">
    <spring:property name="driverName" value="${Driver}"/>
    <spring:property name="url" value="${URL}"/>
    <spring:property name="user" value="${User}"/>
    <spring:property name="password" value="${Password}"/>
</spring:bean>

I had same issue. Place database driver, in the following path.,

AnypointStudio/plugins/org.mule.tooling.server.3.5.***/mule/lib/mule

If you are running from standalone, place the driver jar inside,

mule-standalone-3.5.0/lib/mule

But I am not sure why it is expected database driver when driver is packaged with the deployed app.
