[google-appengine] XMPP Presence: getPresence and isAvailable don't work? sendPresence with PROBE is asynchronous?
Hello everyone. I would appreciate if somebody can clarify these things: 1. XMPPService.getPresence(..).isAvailable() constantly returns 'false' as of today. Is that a temporary behavior, or this methods don't work anymore? 2. Is sendPresence method with PROBE PresenceType asynchronous? 3. Is that correct, that now there is no way to check JID presence (whether user online) synchronously? I have tried to read the docs. As been noted in Version 1.5.5 release notes: ## In the XMPP API, getPresence() is deprecated in favor of using the inbound presence handlers documented in http://code.google.com/appengine/docs/java/xmpp/overview.html#Handling_User_Presence. ## and getPresence marked as deprecated in the current SDK. But in Java world "deprecated" usually used to change syntax or semantics, and leave incorrect method to maintain legacy. But not to mark method as "non working". So it is unclear what really happened with 'getPresence(..).isAvailable()'. Thanks. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Re: XMPP Presence: getPresence and isAvailable don't work? sendPresence with PROBE is asynchronous?
'isAvailable' still does not work for me. Anyhow, banishing of synchronous 'isAvailable' method means a pretty big change. Previously, recipient's JID was all needed, to send a xmpp message. From now on, GAE application have to maintain a 'roster' with statuses of the subscribers. And now it is unable to check recipient's status, and send a message. Status have to be already stored in roster. And app must handle 'error' xmpp responses to adjust that statuses. BTW, there is no methods nor classes in the current GAE Java SDK to parse 'error' stanzas.

[google-appengine] ApiProxy.getCurrentEnvironment().getAppId() returns incorrect app ID
Hello, I am trying to get an id of my app using 'ApiProxy.getCurrentEnvironment().getAppId()'. But the code returns application id with 's~' prefix. Which, I believe, somehow related to HDR datastore. How do I receive a clear id of my application in run-time? I don't really want cut the prefix from the string, because that would looks like a hack. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

Re: [google-appengine] ApiProxy.getCurrentEnvironment().getAppId() returns incorrect app ID
It's the same code. getAppId is not available in static context.

[google-appengine] xmpp.parseMessage(request) has a problem with non-latin characters?
I have created a simple echo xmpp chat bot at gaechat...@appspot.com.
It works fine for latin characters and I get blank squareы for non-
latin. Ihave tried to use
request.setCharacterEncoding("utf-8");
as a first call at doPost, but that doesn't work.
I guess XMPPService.parseMessage method do not takes into account the
encoding of POST request. Probably it is possible to parse post
request by myself (without XMPPService) and to brute force the
character encoding used by requester in Google backed. But if there is
a better way?

There sure is, if xmpp reffers XMPPService instnce :-) The source code
follows.

[google-appengine] Re: xmpp.parseMessage(request) has a problem with non-latin characters?
There is a principal thing to find - if a body of POST request to servlet contains valid unicode data. 1. POST body contains valid data. Then we can get it in binary form and then parse with apache commons or something like that. It will require to guess the encoding of post request. 2. POST contains malformed data. We can do nothing, it all on Google engineers.

[google-appengine] How to apply an "unique" constrain to a field of a class using JDO annotations?
I'have tried to make a field of a class "unique" using different
combinations of JDO annotations. Never successfully.
Here is one of my variations:
---
@Uniques({...@unique(name="MYCONST_1", members={"userJID"})})
@Unique(name="MYCONST_2", members={"userJID"})
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class User
{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Long id;
@Persistent
@Unique(name="MYUSERJID_IDX")
private String userJID;
[..]
---
Is there any way to apply "unique" constrain to a field of a class
using JDO annotations?
