spring 中配置sqlite 路径有关问题

spring 中配置sqlite 路径问题
1、自己写个测试类，调用spring配置文件，然后链接数据库是可以的，但是启动tomcat后，运行时就不行了，
我的bean.xml代码如下：

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:task="http://www.springframework.org/schema/task"

	xmlns:tx="http://www.springframework.org/schema/tx"

	xsi:schemaLocation="http://www.springframework.org/schema/beans 

						http://www.springframework.org/schema/beans/spring-beans-3.1.xsd

						http://www.springframework.org/schema/context 

						http://www.springframework.org/schema/context/spring-context-3.1.xsd

    					http://www.springframework.org/schema/aop

						http://www.springframework.org/schema/tx

						http://www.springframework.org/schema/tx/spring-tx-3.1.xsd">


	<context:annotation-config />

	<!-- 扫描annotation类，过滤Service，Repository -->

	<context:component-scan base-package="com">

		<context:include-filter type="annotation"

			expression="org.springframework.stereotype.Service" />

		<context:include-filter type="annotation"

			expression="org.springframework.stereotype.Repository" />

	</context:component-scan>


	<!-- 定义数据源Bean -->

	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"

		destroy-method="close" lazy-init="true">

		<property name="driverClassName" value="org.sqlite.JDBC" />

		<property name="url" value="jdbc:sqlite:src/config/wy.db" />

		<!-- jdbc:sqlite:src/config/wy.db -->

		<!-- F:/programming/workspace/pmc/src/config/wy.db -->

		<property name="initialSize" value="2" />

		<property name="maxActive" value="20" />

		<property name="maxIdle" value="5" />

		<property name="poolPreparedStatements" value="true" />

	</bean>


	<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">

		<property name="dataSource" ref="dataSource" />

	</bean>

	<bean id="txManager"

		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

		<property name="dataSource" ref="dataSource" />

	</bean>

	<tx:annotation-driven transaction-manager="txManager" />

</beans>

这样配置路径：jdbc:sqlite:src/config/wy.db，写的测试类是可以找到该数据库文件的，
但是启动tamcat后，发送请求，执行到操作数据的方法时 就不行了
报错信息：
