>From your original post, in which you stated "This is my working Spring datasource.xml:" <bean id="dataSource" class="com.ax.dashboard. datasource.AxRoutingDataSource"> <property name="targetDataSources"> <map key-type="java.lang.String"> <entry key="first" value-ref="firstDatasource" /> <entry key="second" value-ref="secondDataSource" /> </map> </property> <property name="defaultTargetDataSource" ref="firstDatasource" /> </bean> In spring you are building a map of data sources that are also defined in spring. Why not build a map of data sources that are defined in context.xml and spring looks them up? You say that you need variable amounts of databases, but the code you posted and said "this worked" doesn't support this - to add a new datasource you would have to update spring config. If you really need variable databases, then some custom code to load a custom configuration of such data sources might be the way to go. Then just use a resource element in context to get tomcat to load that for the instance. Chris
