[appengine-java] Re: How can I keep the data saved in JDO datastore?

[l.denardo]

Data are persistent across deploys.
You only need to keep the same name for the entities and have
compatible models.
If you cannot see old data, probably you have done changes to your
data model. Anyway, you should be able to see your application data
from the admin console (datastore viewer). This can help you determine
whether you are having trouble with data persistence or with changes
in your data model. You should see all your previously existing
entities.

If you mean "update local data to live servers", so you can use data
you produced on your local machine to initialize your app, there's a
tool called bulk loader. I never used it but there's an interesting
post on Ikai Lan's blog
http://ikaisays.com/2010/06/10/using-the-bulkloader-with-java-app-engine/

I have a com.google.appengine.api.datastore.Text object stored in the
datastore, when examined through the datastore viewer, it reads as it should
e.g. 'this is a test'

I retrieve it with a

public Text getData() {
return data;
} 

then write it out with getWriter, however I'm getting 
instead of just 'this is a test'

Sure I'm doing something daft! I'm rather new to java.

Thanks in advance.

Re: [appengine-java] mapreduce job is not aborted

[Cyrille Vincey]

"Abort" button doesn't work indeed.
When I want to abort a mapreduce job, I directly mapreduce-related entities
in the datastore viewer : MapReduceStat and ShardDontKnowWhat.

[appengine-java] Change namespace on existing entities

[aswath satrasala]

Hello,
I have an multi-tenant app-id, and I have designed on partitioning the
entities based on  url parameters.  I am not using the namespace yet.

For example,

Tenant {
@Id name+email;
}

class Party {
  @Long id
  Key tenantKey;  // partitioning/filtering
  String fname
}

Now, I am planning to use the NamespaceManager for the Party entities.  I
want to use the mapreduce and apply the namespace on the existing Party
entities.
Can a namespace be changed from empty to certain value on the existing
entity.

[appengine-java] Re: Change namespace on existing entities

[Didier Durand]

Hi,

http://code.google.com/appengine/docs/java/javadoc/com/google/appengine/api/NamespaceManager.html
says

"When a namespace aware class (e.g., Key, Query and MemcacheService)
is constructed, it determines which namespace will be used by calling
get() if it is otherwise unspecified. If get() returns null, the
current namespace is unset and these APIs will use the empty ("")
namespace in its place. "

So, I would guess that you have to recreate / copy your entities after
having set namespace via NameSpaceManager.set() if you want to move
them into a new namespace

didier

[appengine-java] Access to Subversion (SVN) from App Engine

[Didier Durand]

Hi there,

I would like to be able to use SVN from Google App Engine to retrieve
files from the repository, check changes, make diffs, etc...

I used SvnKit from a regular JVM on a server: that would satisfy my
needs

But, according to 
http://old.nabble.com/Google-App-Engine-Support-td28219433.html
, I understand that the use of raw sockets by SvnKit makes it unsable
on Google App Engine as GAE restricts network access to http.

a) Has somebody tried SvnKit on Google App Engine and can confirm the
issue ?
b) Is there any other proper way to access SVN from App Engine ?

Thanks,
didier

Re: [appengine-java] Access to Subversion (SVN) from App Engine

[Paul Hammant]

I'm interested in this too.  Though not quite in the same way as you.

I wish for the provision of GoogleCode's Svn-on-Bigtable capability through
the AppEngine platform.  I want to do PUTs to an AppSpot app that could (if
my servlet is so configured) fall through to an underlying Subversion
provision.

[appengine-java] Re: 1.3.8 Console Logging Issue

[madein]

Hi,
is anyone from App Engine team is aware of this?
I can raise new issue in the bugtracer (http://code.google.com/p/
googleappengine/issues/list) but at this moment AppEngine has 1596
registered defects. Is there a point in registering another one, maybe
you could fix this skipping the red tape?

br,
M.

[appengine-java] java.util.HashMap for field not marked persistent

[kapliars]

Hi there, I'm trying my first attempt on GAE and face wierd exception
(I'm new to JDO too):

I have a data class with a map field, intended to be used internally:

@PersistenceCapable(identityType=IdentityType.APPLICATION)
public class ElementAnalysis {
...
//not persistent
private Map amounts = new HashMap();

}

then I try to save it


@Override
public Long save(ElementAnalysis analysis) {
PersistenceManager pm =
ManagerFactory.get().getPersistenceManager();
try {
pm.currentTransaction().begin();
pm.makePersistent(analysis);
pm.currentTransaction().commit();
return analysis.getKey();
} finally {
if (pm.currentTransaction().isActive()) {
pm.currentTransaction().rollback();
}
pm.close();
}

}


and suddenly I see:

[appengine-java] appengine-tools-api.jar not found

[Muki]

Hi guys!

I just switched from the Python SDK to Java for a project and I
downloaded the newest SDK (1.3.8). However whenever I run
dev_appserver.sh it says that it can't find the appengine-tools-
api.jar. When I try to find it on my machine I can't seem to be able
to locate it either. Where do I get it? How? Has this been deprecated
and not changed in the tutorial yet?

Best,

Muki

Re: [appengine-java] datastore viewer's GQL

[Ikai Lan (Google)]

I'm guessing this is a custom rolled User object. Here's how you'd likely do
it:

SELECT * FROM User where __key__=KEY('User', 100100)

Strange, if you unzip the download, it should just be here:

appengine-java-sdk-1.3.8/lib

Did you download the file from here?

http://googleappengine.googlecode.com/files/appengine-java-sdk-1.3.8.zip

It should be. Kind names don't include the full package name. I'm assuming
you're using JDO/JPA?

[appengine-java] Re: How can I keep the data saved in JDO datastore?

[qiwawa]

Thanks Lorenzo. I'd prefer if Google AE can provide a way for us to
back up the data and restore it back.

An export/import tool will be the most useful and make me feel better
that my data is safe.

Is there a way to back it up?

Thanks again.

[appengine-java] Re: Newly deployed app doesn’t se em always reflected on the server.

[nnhobbit]

Is version number change necessary? If I deploy it with the same
version number, shouldn’t the old one simply be replaced?

The page is not cached and I’m not behind any proxy. I’m now thinking
it’s more likely there’s a zombie process running?
