dwr.xml 配置代码；

	<!-- DWR核心配置-->
	<dwr:configuration>
<dwr:convert type="bean" class="com.dwr.demo.web.*">
</dwr:convert>
</dwr:configuration>
<bean name="userdwr"
class="com.dwr.demo.web.testAction">
<dwr:remote javascript="UserDwr">
 <dwr:include method="login"/><!---校验登录名称-->
<dwr:include method="checkOldpwd" /> <!--校验密码-->
</dwr:remote>
</bean>	
</beans>

web.xml ；配置代码
