Spring 3 - Multiple file upload - MultipartFile

[sachin pachpute]

I am trying to upload multiple files using spring 3, it is picking only the fist file. I browsed through a few posts available online but didnt get clear solution.

JSP

<form:input path="fileData" tabindex="10" id="file" value="Add Pictures" type="file"/>
<form:input path="fileData" tabindex="10" id="file" value="Add Pictures" type="file"/>

Bean

private List<MultipartFile> fileData;

and getter / setters ...

Controller

@RequestMapping(value = "/save", method = RequestMethod.POST)
	public String saveArticle(@Valid Article article,
			BindingResult result, HttpServletRequest request, Model model) {

                        List<MultipartFile> multipartFile = article.getFileData();
			logger.debug("Size of the multipart file :"+multipartFile.size());
further iteration and processing to write file on a disk....

dispatcher-servlet

        <bean id="multipartResolver" 
        class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> 
        <property name="maxUploadSize" value="1000000"/>     
    </bean>

I earlier tried below in JSP but it gave me error...

<form:input path="fileData[0]" tabindex="10" id="file" value="Add Pictures" type="file"/>
<form:input path="fileData[1]" tabindex="10" id="file" value="Add Pictures" type="file"/>

I was going through Spring version changelog and noticed below line for version 3.0.4

"* WebDataBinder and @MVC request params detect and introspect MultipartFile arrays as well"

looks like I need to upgrade to latest version as i am using 3.0.1

I should have done this any ways to avoid any version issues.. lesson learnt!!!
