754
Download the Struts2 jQuery Plugin and do it like you normaly do it with Struts2.
<%@ taglib prefix="s" uri="/struts-tags"%>
<%@ taglib prefix="sj" uri="/struts-jquery-tags"%>
<html>
<head>
<sj:head/>
</head>
<body>
<s:form id="form" action="AjaxTest">
<s:file name="myFile" ... />
<sj:submit value="Submit Form" targets="myAjaxTarget"/>
</s:form>
<div id="myAjaxTarget">
</div>
</body>
</html>
If you want to return json data to client, you can get the error that a file download dialog appear to download json as a text file. I use struts2-json plugin so to fix this error, just add the following config to your action in struts.xml
<param name="contentType">text/plain</param>
my sample
<action name="uploadFile" class="fileUploadAction">
<interceptor-ref name="fileUploadStack"/>
<result name="input">/WEB-INF/pages/uploadForm.jsp</result>
<result name="success" type="json">
<param name="excludeProperties">
fileStoreManager, file
</param>
<param name="contentType">text/plain</param>
</result>
<result name="cancel" type="redirectAction">mainMenu</result>
</action>
