Problem uploading files in MVC portlet

[alex wom, modifié il y a 12 années.]

In my MVC portlet I have problems uploading files. Some time the files are uploaded with the correct extension some time without extension. I'm using the tomcat bundle and in liferay-portal-6.0.6/tomcat-6.0.29/temp after the upload I find upload_00000033, upload_00000034 ... without extension. The portlet I'm developing need to upload a zip file and it doesn't work. But some time it works ....
The view.jsp is the following.
<aui:form action="<%= contentImportURL.toString() %>" enctype="multipart/form-data" method="post">
...
<liferay-ui:message key="import_file" />
<aui:input cssClass="lfr-input-text-container" label="import-file" name=import_file" type="file" />
</aui:form>

And the action is in the following:
public void doImport(
ActionRequest actionRequest, ActionResponse actionResponse)
throws Exception {
try {
checkPermissions(actionRequest);
} catch (PrincipalException e) {
SessionErrors.add(actionRequest, "NotCommunityAdministrator");
}
UploadPortletRequest uploadRequest = PortalUtil
.getUploadPortletRequest(actionRequest);
String cmd = ParamUtil.getString(uploadRequest, Constants.CMD);
String type = ParamUtil.getString(uploadRequest, "type");
String templateId = ParamUtil.getString(uploadRequest, "templateId");
String structureId = ParamUtil.getString(uploadRequest, "structureId");
File importFile = uploadRequest.getFile("import_file");
File transformFile = uploadRequest.getFile("transform_file");
String importFileName = importFile.getName();
String importSet = ParamUtil.getString(uploadRequest, "import_set");
String description = ParamUtil.getString(uploadRequest, "description");
long groupId = ParamUtil.getLong(uploadRequest, "groupId");
...

Hi Alex,

What you are getting is the file that your server, Apache Tomcat, generates in its "temp" directory. I had a similar problem but with struts2 portlets. As a quick solution I make a "trick" with this jQuery snippet:

jQuery(document).ready(function() {		
		
	jQuery('#submitYourForm').click(function() {
		var element = jQuery("#file")[0];
		var hidden = jQuery("#fileName")[0]; 
		hidden.value = elemento.value;	
	});
});

And in my jsp:

<input type="hidden" name="nombreFichero" id="nombreFichero">
.../...
<input type="file" name="file" id="file">
<input type="submit" value="Submit File" id="submitYourForm">

And in my Action class I had just a parameter for getting the value of "fileName". Maybe it is not the best and elegant approach, but it works...

Hope it helps,

Luis
