Class UploadBlobServlet

java.lang.Object
  javax.servlet.GenericServlet
      javax.servlet.http.HttpServlet
          com.google.appengine.api.blobstore.dev.UploadBlobServlet

All Implemented Interfaces:

java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public final class UploadBlobServlet
extends javax.servlet.http.HttpServlet

UploadBlobServlet handles blob uploads in the development server. The stub implementation of BlobstoreService.createUploadUrl(java.lang.String) returns URLs that are mapped to this servlet.

Its primary responsibility is parsing multipart/form-data or multipart/mixed requests made by web browsers. To minimize dependencies in the SDK, it does using the MimeMultipart class included with JavaMail.

After the files are extracted from the multipart request body, they are assigned BlobKey values and are committed to local storage. The multipart body parts are then replaced with message/external-body parts that specify the BlobKey as additional parameters in the Content-type header.
