I would like to find out how to parse a xml file that has been uploaded to
the blobstore. Below is the code that I have.
Can any one recommend a solution to this? At the moment my project uploads
the xml file and serves it through a serve.java file
(file Upload.java):
package uploaddata;
import java.io.IOException;import java.util.Map;
import javax.servlet.ServletException;import
javax.servlet.http.HttpServlet;import
javax.servlet.http.HttpServletRequest;import
javax.servlet.http.HttpServletResponse;
import com.google.appengine.api.blobstore.BlobKey;import
com.google.appengine.api.blobstore.BlobstoreInputStream;import
com.google.appengine.api.blobstore.BlobstoreService;import
com.google.appengine.api.blobstore.BlobstoreServiceFactory;import
com.google.appengine.api.files.AppEngineFile;
public class Upload extends HttpServlet {
private static final long serialVersionUID = 1L;
private BlobstoreService blobstoreService =
BlobstoreServiceFactory.getBlobstoreService();
public void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
@SuppressWarnings("deprecation")
Map<String, BlobKey> blobs = blobstoreService.getUploadedBlobs(req);
BlobKey blobKey = blobs.get("myFile");
if (blobKey == null) {
res.sendRedirect("/");
} else {
System.out.println("Uploaded a file with blobKey:
"+blobKey.getKeyString());
//BlobstoreInputStream is = new BlobstoreInputStream(new
BlobKey("blobKey"));
res.sendRedirect("/serve?blob-key=" + blobKey.getKeyString());
}
}
}
