Yeah, you have to do the identification in the server, there are various libraries that makes it easy.
- http://sourceforge.net/projects/mime-util MimeUtil.registerMimeDetector("eu.medsea.mimeutil.detector.MagicMimeMimeDetector"); File f = new File ("c:/temp/mime/test.doc"); Collection<?> mimeTypes = MimeUtil.getMimeTypes(f); System.out.println(mimeTypes); - http://sourceforge.net/projects/jmimemagic/ Magic parser = new Magic() ; MagicMatch match = parser.getMagicMatch(new File("gumby.gif")); System.out.println(match.getMimeType()) ; - http://lucene.apache.org/tika/ File f = new File("C:/Temp/mime/test.docx"); FileInputStream is = new FileInputStream(f); ContentHandler contenthandler = new BodyContentHandler(); Metadata metadata = new Metadata(); metadata.set(Metadata.RESOURCE_NAME_KEY, f.getName()); Parser parser = new AutoDetectParser(); parser.parse(is, contenthandler, metadata); System.out.println("Mime: " + metadata.get(Metadata.CONTENT_TYPE)); Source: http://www.rgagnon.com/javadetails/java-0487.html Manolo Carrasco On Tue, Sep 29, 2009 at 8:44 PM, Thomas Broyer <t.bro...@gmail.com> wrote: > > > > On 29 sep, 13:59, "vaibhav.saxena" <vaibhav....@gmail.com> wrote: > > Hi, > > I am using form panel in my GWT client code.
