[appengine-java] java.lang.NoClassDefFoundError: java.rmi.server.UID ->>>>>using commons-fileupload-1.2.1.jar
Hi Guys, Im trying to store and image with GWT to Google App engine, I'm using the packages: commons-codec-1.4.jar commons-fileupload-1.2.1.jar commons-io-1.4.jar to get the widgets from the formPanel that I'm sending to the server which contain the widgets FileUpload that has my image. When I'm using this packages to recover the image and store it I've the following error: java.lang.NoClassDefFoundError: java.rmi.server.UID is a restricted class.

[appengine-java] Use Blobstore Java API with GWT
Hi Guys,
Im trying to upload images using the new Blobstore API to the app
engine with GWT.
Ive created a FormPanel() to upload the images to the app engine, but
when im trying to set up the action in the form using
BlobstoreService, i cant because the import com.google.appengine
cannot be resolved.
My question is: how can I set up the action on the form using the
BlobstoreService?? I've this code in the client side:
import com.google.appengine.api.blobstore.BlobstoreService;
FormPanel form = new FormPanel();
form.setEncoding(FormPanel.ENCODING_MULTIPART);
form.setMethod(FormPanel.METHOD_POST);
BlobstoreService blobstoreService =
BlobstoreServiceFactory.getBlobstoreService();
form.setAction(blobstoreService.createUploadUrl("handizo/
upload"));
error: import com.google.appengine cannot be resolved.
Ive also tried to setup the action without the BlobstoreService, but
when the form is read in the server side using the BlobstoreService:
private BlobstoreService blobstoreService =
BlobstoreServiceFactory.getBlobstoreService();
protected void doPost(HttpServletRequest req, HttpServletResponse
resp)
throws ServletException, IOException {
Map blobs =
blobstoreService.getUploadedBlobs(req);
BlobKey blobKey = blobs.get("myFile");
if (blobKey == null) {
resp.sendRedirect("/");
} else {
resp.sendRedirect("/serve?blob-key=" +
blobKey.getKeyString());
}
I've this other error saying me that I've to set up the action using
the BlobstoreService.
Error: Must be called from a blob upload callback request.
at
com.google.appengine.api.blobstore.BlobstoreServiceImpl.getUploadedBlobs
(BlobstoreServiceImpl.java:97)
at com.handizo.server.service.FileUploadAnnouncementServlet.doPost
(FileUploadAnnouncementServlet.java:23)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:713)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:806)
So its possible to user the BlobstoreService with GWT by the moment??
Thanks in advance :-)

Hi Guys, I've a simple question, I'm using Java App Engine and I need to store multilingual data like 'ñ' character. Storing it as a unicode String, when I retrieve it, I'm getting the following one '?'. Does any one know how to store them? I need to store data with different languages.
