I use dwr2.0.1 and spring2.5, the dwr remote method calling is ok for me.
1. web.xml
Code:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</web-app>
cn.mynode.validation.AjaxFormValidator is my java class used for dwr service.
2. I use annotation configure instead of dwr.xml, Here is my Java class
Code:
@RemoteProxy(name = "AjaxFormValidatorJS", creator = SpringCreator.class, creatorParams = @Param(name = "beanName", value = "ajaxFormValidator"))
public class AjaxFormValidator implements ApplicationContextAware {
//@RemoteMethod
public String sayHello(String msg) {
return "FormValidator:Hello world " + msg + "!";
}
}
3. in spring configurateion a bean is defined like this,
applicationContext.xml
Code:
<bean id="ajaxFormValidator" class="cn.mynode.validation.AjaxFormValidator" >
</bean>
4. use javascirpt in my jsp file like this:
Code:
<?xml version="1.0" encoding="utf-8" ?>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

</div>
<div>
<input type="submit" value="创建用户" />
</div>
</form:form>
</div>
</div>
</body>
</html>
5. a ajaxValidate.js file like this:
Code:
function validate(inputArray) {
AjaxFormValidatorJS.sayHello("sammi", handleValidationResponse);
}
function handleValidationResponse(response) {
alert(response);
}
