[appengine-java] Re: ImageService from dev server
Starman: Unfortunately that solution won't work for the deployed code working with the *real* blobstore/image service, as the serving URL returned is a real URL for the ImageService on a different server to your application, so you need to store the host and port. I'd rather not have specific code for dev_server and production if I can avoid it Couldn't the dev_server code for Blobstore/ImageService just return the correct hostname in the serving URL? = If experts consider that a bug in dev_server then I'd be happy to submit it.

[appengine-java] Re: ImageService from dev server
Didier:
Forgot to clarify this in the previous post.
I have no problems to upload (and even delete) files to the blobstore
in local dev_server.
The problem is the URL returned by the call:
url = imagesService.getServingUrl(blobKey);
from the ImageService code when running in dev_server
it returns
http://0.0.0.0:80/_ah/img/{key}
which is then NOT served.

[appengine-java] Entity relations (JPA vs lowlevel API)
Hi there, I'm searching for information of entity relation ships in appengine. JPA for example supports relations between entites (one-to-one, ont-to-many, many-to-many). As far as I know by know the underlying datastore doesn't direktly support this and not join queries (different entities). How do you store Customer - Orders in the datastore? Is there low level API example code? Would I store an entity Customer with attributes and a list of order ids? Any help highly appreciated.

Re: [appengine-java] Running Google App Engine from within a HSM.
Hi Ikai, Thank you for your fast response. I'm not sure I understand the question. Are you looking to run the GAE SDK inside your own hardware? Or are you looking to run something like AppScale (http://code.google.com/p/appscale/) with the security module? I am looking to run something like AppScale (http://code.google.com/p/appscale/ ) with the security module? Specifically, I was wondering if it was possible to run AppServer (part of AppScale) inside a hardware security module (HSM), where that HSM is capable of running Java Standard Edition software. So in a hybrid cloud deployment some of my business logic processing particularly sensitive information (social security numbers, credit cards, and so on) is running entirely within the protection of a hardware security module (running AppServer) managed at my site, and the remaining parts of my business logic responsible for processing less sensitive data is running on the public cloud provided by Google.

[appengine-java] Re: blobstore - map returned empty
What I do is remove the prot:ip:port prefix if the ip is 0.0.0.0
before I store the url. In dev, a relative path is OK. In prod, I
store exactly what is returned.

What I tried now - is created a dialog with simple file upload field

May be I will come back to other code and see what causing it.
Though another thing which I came across is that some time
ImageService ( String imageURL =
imagesService.getServingUrl(blobKey); ) returns serving url with ip
address i.e. instead
/_ah/img/iS_QaJQHwq-tmmA4_5i6kw
it returns
http://0.0.0.0:/_ah/img/iS_QaJQHwq-tmmA4_5i6kw
In such case image does not get display as incorrect local ip address

upload widget:

Here's the servlet that handles uploads:

I've seen this happen before when the name isn't set correctly. Can you look
into the generated source using a tool like Firebug to see if the form is
being generated correctly?

Hi Ikai,
Upload page is a composite, in which I have a decorator panel which

As for servlet code:
public void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
{
String userIdStr =
req.getParameter(IAppConstants.PARAM_UserId);
MapString, BlobKey blobs =
blobstoreService.getUploadedBlobs(req);
BlobKey blobKey = blobs.get(IAppConstants.PARAM_MyFile);
.
.
.
blobs returned is empty and so blobKey is null.
IAppConstants.PARAM_MyFile is name of upload field at client side
i.e.
uploadField.setName(IAppConstants.PARAM_MyFile);
In servlet if I do
String myFile =
req.getParameter(IAppConstants.PARAM_MyFile);
then myFile is also null.
Upload form at client does have
uploadForm.setEncoding(FormPanel.ENCODING_MULTIPART);
uploadForm.setMethod(FormPanel.METHOD_POST);
Any suggestions?
Thanks.

Great tip but it's not working. Running the test updates the mod date

I'm also configuring a LocalUserServiceTestConfig for a logged in

Is another setup step needed?
I'd like a unit test to trigger all auto-index because my app has many
possible combinations of query filters.

This way, you can even write tests against a previously generated
local_db.bin if you want.
