Problem using #{jobExecutionContext[${batchConfig.resources.sourceDatabase}]}

[vinvh]

Hi,
I am using Spring Batch 2.0.0 and try to use the late binding feture to load the data source through execution context. Here is the bean defination -

<beans:bean id="testSRC" class="org.springframework.orm.ibatis.SqlMapClient FactoryBean">
<beansroperty name="dataSource" value="#{jobExecutionContext[${batchConfig.resources.sourceDatabase}]}" />
<beansroperty name="configLocation" value="ibatis-config.xml" />
</beans:bean>

The data source is fetched from JNDI resource and loaded in execution context with Job listener in beforeStart().

When I run this batch I get following error -

org.springframework.beans.TypeMismatchException: Failed to convert property value of type [java.lang.String] 
to required type [javax.sql.DataSource] for property 'dataSource'; 
.......

So is it means that through late binding only String can be passed?
