现在的好多项目，一般一个web应用会同时链接多个数据源，不知道大家是如何配置的？不知道如下做法有没有什么不好的地方。

一、首先配置hibernate数据源：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd">
<beans>
  <!--1、Oracle 数据源配置-->
  <bean id="oraclesessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="configLocation">
      <value>WEB-INF/classes/oracle-h.cfg.xml</value>
    </property>
  </bean>
  <bean id="oracletransactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory">
      <ref local="sessionFactory" />
    </property>
  </bean>
<!--2、SQLServer 数据源配置-->
  <bean id="sqlServersessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="configLocation">
      <value>WEB-INF/classes/sqlserver-h.cfg.xml</value>
    </property>
  </bean>
  <bean id="sqlServerTransactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory">
      <ref local="sqlServersessionFactory" />
    </property>
  </bean>
<!--3、其他数据源配置-->
.................

 2、配置spring的事务拦截器(AOP):

<!--1、oracle数据源 事务管理拦截器-->
    <tx:advice id="oracleTxAdvice" transaction-manager="oracletransactionManager">
	<tx:attributes>
		<tx:method name="find*" read-only="true"/>
		<tx:method name="get*" read-only="true"/>		<tx:method name="notx*" propagation="NEVER"/>
		<tx:method name="*" rollback-for="自定义Exception"/>
	</tx:attributes>
    </tx:advice>
<!--2、sqlserver数据源 事务管理拦截器-->
    <tx:advice id="sqlserverTxAdvice" transaction-manager="sqlservertransactionManager">
	<tx:attributes>
		<tx:method name="find*" read-only="true"/>
		<tx:method name="get*" read-only="true"/>		<tx:method name="notx*" propagation="NEVER"/>
		<tx:method name="*" rollback-for="自定义Exception"/>
	</tx:attributes>
    </tx:advice>
<!--3、其他数据源 事务管理拦截器-->
.................
<!--配置多数据源的事务拦截器-->
    <bean id="serviceAutoProxyCreator" class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
        <property name="beanNames">
            <list>
                <value>*Service</value>
            </list>
        </property>
        <property name="interceptorNames">
            <list>
                <value>oracleTxAdvice</value>
                <value>sqlServerTxAdvice</value>
                <value>XXXXXTxAdvice</value>
            </list>
        </property>
    </bean>

   这样就可以配置多个数据源了。

最近温习了一下XML，对XLS、XSD是比较熟悉的，但对XLL没用过，不知道那位仁兄用过，能否给讲讲啊？

2、我刚测试，如果不适用tiles，即不用DelegatingTilesRequestProcessor，而是在配置文件struts-config-xxx.xml里action中直接使用DelegatingActionProxyforward ，在forward中直接使用jsp就没有问题。,     看来使用DelegatingTilesRequestProcessor处理tiles有问题，有哪位用过DelegatingTilesRequestProcessor处理tiles，请指点一下？

3、当前我还发现了一个现象，就是使用了DelegatingTilesRequestProcessor，则配置文件struts-config-xxx.xml中action里的parameter就不起作用了。 请大家参考我上面提供的信息，诊断一下是哪里出了问题？谢谢。
