I am working on this right now. yes, I've seen it is a bit more complicated... I have tried it this way : FileItem item = (FileItem) itr.next(); | ZipFile zipFile = new ZipFile(item.getName()); in the CMSAdminPortlet code (a copy of it). and it seems to work. the FileItem javadoc says getName() is not reliable. it is working with : Internet Explorer 6 and windows XP. but not working with opera 8.5. getName() return only the file name, not the base path. I don't know how to solve this. may be searching in the zip api (which I don't know that much). is there a way to store a file temporarily in the jboss temp folder (or some other places). then reopen it with ZipFile ?
