[appengine-java] Re: Blobstore vs. Datastore for HTML files
Brandon, Have you considered storing HTML in compressed form as Datastore blobs? Being plain text HTML should have very high compression ratio. * java.util.zip.GZIPOutputStream is usually no worse than x5, but it is slower * com.ning.compress.lzf.LZFOutputStream should yield x3 compression, but it is faster than GZIP Cheers, Yegor On May 5, 8:14 pm, Brandon Donnelson branflake2...@gmail.com wrote: Entity limit is 1MB total.

[appengine-java] Re: Blobstore vs. Datastore for HTML files
I haven't yet. Are you storing compressed to save on cost? I am mainly working with images at the moment and sending them to the blobstore so I haven't had the need to consider that yet. Thats interesting point if you are trying to save on cost of storage that way. How much time does it take to compress java.util.zip.GZIPOutputStream?

[appengine-java] xml parsing on GAE servers acts weird
Hey guys,
I created an app where a user can upload an xml, I display the nodes
in a GWT table then the user selects the nodes he/she wants to
download. Sounds easy, works perfectly in hosted mode.
I use only the base xml parsing, no 3rd party jars in the project
(aside from commons-fileupload-1.2.1.jar, commons-io-1.3.2.jar,
gxt-2.2.3-gwt22.jar).
Here's the code I use for parsing the XML:
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.NodeList;
...
public static Document getXml(InputStream stream) throws
ParserConfigurationException, SAXException, IOException {
DocumentBuilder parser =
DocumentBuilderFactory.newInstance().newDocumentBuilder();
// Parse xml data
Document xml = parser.parse(stream);
return xml;
}
It's working perfectly in hosted mode, but when I upload it to the
appengine servers I get the following exception:

Hi Marcel, Yes, it should work in a production server, not on the development server. Are you trying this on the production environment?

How would I send a 'deferred' Task to a specific queue? Like this?

So that's great. Now I've added queue.xml to WEB-INF folder with: queue-entries queue namedefault/name rate1/s/rate retry-parameters min-backoff-seconds1/min-backoff-seconds task-retry-limit5/task-retry-limit /retry-parameters /queue queue nameemail-queue/name rate1/s/rate retry-parameters min-backoff-seconds5/min-backoff-seconds task-retry-limit3/task-retry-limit /retry-parameters /queue queue nameother-queue/name rate1/s/rate /queue /queue-entries I've done some testing and inside the task I just throw an Exception to test the retry parameters. What I see is that the retry parameters are not picked up (at least in Development server). I keeps trying (more than the 3 time retry limit) and the backoff seconds are also not used. I see the first 3 or 4 retries within 2 seconds or so, and interval starts increasing, nut 5 between each retry. Could it be that the queue.xml is not picked up or I did something wrong?

Like any task. You can add a deferred task to any queue. - Is it possible to change throttling configuration per Deferred task queue? DeferredTasks may be placed in any queue. Just a note. You seem to be conflating handlers/servlet mappings with queues. There is nothing stopping you from having a single handler accept requests from any queue. In the case of the TaskOptions.payload(DeferredTask) method, it will automatically set the handler url for you if it is not otherwise specified. URL is somewhat irrelevant for deferred task since the run() method you define is essentially the entry point for the task.

Re: [appengine-java] xml parsing on GAE servers acts weird
You don't show what stream you're passing in so I can't comment on if that
might be an issue but you should try setting namespaceAware to true like
this to see if it will cause the DeferredDocumentImpl to not be used. I use
code like this and works fine for me.
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder docBuilder = dbf.newDocumentBuilder();
Document document = docBuilder.parse(inputStream);

[appengine-java] JPA fetching class.anotherClass.attribute
Hello, I am currently working for a university project about digital
humanities, basically its an app where you can read books and make and share
annotations to it. Im facing a problem that got me stuck for 4 days long
now, and I do not know what to do.
Here is the tech spec: Annotatio: has many AnnotationType. Lets say that I
have to AnnotationTypes i.e ''sadness and tradegy. Then the app
administrator realises that both AnnotationType are the same so he wants to
merge sadness and tradegy to be AnnotationType tradegy only.
So in order to make this my approach is to first grab all the annotations
whose annotationType.getName() == comedy and then set the new
AnnotationType in the whole list. here's the code.
@Entity
@Table(name = annotation)
public class Annotation implements Serializable, IsSerializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Key id;
private String bookId;
@Basic
@ManyToOne(cascade = CascadeType.PERSIST, fetch = FetchType.LAZY)
private AnnotationType annotationType;
}
@Entity
@Table(name = annotation_type)
public class AnnotationType implements Serializable, IsSerializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Key id;
private String name;
@Basic
@OneToMany(cascade = CascadeType.ALL,mappedBy = annotationType)
private ArrayListAnnotation annotations;
}
And heres the method fusionAnnotationType
public int fusionAnnotationTypes(AnnotationType annotationType1,
AnnotationType annotationType2) throws GeneralException,
AnnotationTypeNotFoundException, NullParameterException {
int total = 0;
ListAnnotation annotations2 = new ArrayListAnnotation();
ListAnnotationType annotationTypes2;
entityManager = EMF.get().createEntityManager();
if (annotationType1 == null || annotationType2 == null) {
throw new NullParameterException(Parameter cant be null in
method deleteDnServices);
}
try {
String sql2 = SELECT a FROM Annotation a WHERE
a.annotationType + annotationType2;
annotations2 = entityManager.createQuery(sql2).getResultList();
AnnotationType auxAnnotationType = new AnnotationType();
for (int i = 0; i annotations2.size(); i++) {
annotations2.get(i).setAnnotationType(annotationType1);
saveAnnotation(annotations2.get(i));
}
} catch (Exception e) {
entityTransaction.rollback();
throw new GeneralException(Exception in method
fusionAnnotationTypes: + e.getMessage());
} finally {
if (entityManager.isOpen()) {
entityManager.close();
}
}
return total;
}
when executing it jumps this message error: Portion of expression could not
be parsed: @164a05d
I have also tried to fetch SELECT a FROM Annotation a WHERE
a.annotationType.name + annotationType2.getName(); and annother exception
occured: Can only reference properties of a sub-object if the sub-object is
embedded.
Can you please help me out on this, I really do not know what to do. another
thing that I also tried was fetching the AnnotationType and then getting its
annotationList and do the same project, but it complains again throwing
another exception about entity groups.
I really need some help.
cheers.
Kido.

[appengine-java] Re: Blobstore vs. Datastore for HTML files
Ikai, this is what a 1.5MB HTML page looks like: http://svnbook.red-bean.com/en/1.5/svn-book.html :) I can't think of many other examples, outside of single page user guides for open source projects. So your point is very fair, especially given the average HTML files size is ~25 KB. 1MB XML files, however, are not out of the question. Have you ever seen the XML that MS Office products output? It is very verbose, and in my experience ~250 KB for an average sized document. If you embed images you can easily exceed 1MB. What if I wanted to store MS Project XML files for my Chrome App: https://chrome.google.com/webstore/detail/kdecagaipaomhgmddggocgibjclimaol?hl=en-US ? Luckily, for this particular project i'm not working with MS XML files, so I can simplify my solution. I've taken the approach where I store editable files in the datastore (xml, xsl, html, css, etc) and non-editable files in the blobstore (images, pdfs, etc). I like the ability to update records, as opposed to constantly creating new blobs and deleting the older versions.
