List items = servletFileUpload.parseRequest(req);

All time i try to upload a file by an external portlet(struts) , size items is zero.
In debug mode all work fine on windows whereas when debug on Linux parseRequest return e List with 0 element.

Are there any solutions? Same problem was in Liferay 4.3 and now in StrutsPortlet Liferay 5.
