java - Liferay: how can i upload a image from portlet preferences? -


using liferay 6.2, i'm trying create portlet image displayed.

i have done need able change image preferences uploading new one. have form upload file i'm not able upload file , show on portlet.

this form in edit.jsp

<aui:form action="<%=editpreferencesurl%>" method="post"> <aui:input label="image" name="image" type="file"/> <aui:button type="submit" /> </aui:form>

this renderurl:

<portlet:renderurl var="editpreferencesurl">    <portlet:param name="mvcpath" value="/html/folder/edit.jsp" /> </portlet:renderurl>

the editpreferencesurl mention renderurl - posting form you'll need actionurl.

a renderurl typically used show raw form (e.g. it's fine use link edit mode form) not updating data. during render portlet cannot change state, during action can.
