[appengine-java] Confirmation of Google Multi-Tenant app policy
Hi Now I am planning to start free project management service => http://www.chainofasker.com/ by using Google App Engine When I try to provide this free project management service, problem is server fee because once I release this service, I can not expect how many user come to this site and use free service. So I want to ask user to have their dedicated server if they want use stable service. Procedure is following User create User own account at Google app engine site. User nominate me as a administrator or invite me as a developer. I install server software. User remove me from administrator list. User start using my service Is this meet Google App Engine’s terms of use? I found related article which is posted by Jason but now I can not find it url so I post previous multi-tenant discussion image to here => http://www.chainofasker.com/muti-tenant-past-post I think above procedure is keeping Jason’s recommendation. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] DataStoreTimeOutException when using session at production mode
Hi I got DatastoreTimeoutException when I using HttpSession at production mode. This code does not create error at local development environment. Purpose to use session is cashing userID(google e-mail string ) when user login at first time. So I created Session_User class which have SeesionID, UserID, and UserNickName propaty and store this instance to memcashe(Key:SessionID. Value Session Instance) and use memcash to identify user when they access server 2nd time. I am not using HttpSession.setAttribute method because I can use Google userService.getCurrentUser() method when cashed data is expired. It is written that when we add true to appengine-web.xml then GoogleSDK automatically creates datastore entities of the kind _ah_SESSION but I could not find _ah_SESSION class in my source code. So Is this the reason for this DatastoreTimeoutException? And if so what should I do to make GoogleSDK creates datastore entities _ah_SESSION? <<> A server error has occurred.

[appengine-java] memcache.InvalidValueException caused by java.io.InvalidClassException
Hi
I got following exception when I changed cashing class(M_SitePolicy
class) . I have read related post and understand that I must remove
previous cashed object and put serialVersionUID to my M_SitePolicy
class to avoid recurrence of this kind of error.
So I put serialVersionUID = 2001 to M_SitePolicy class and add
following program to overwrite exsisting cash by new one.
Program.
public static void SitePolicy_Clear()
{
try
{
CacheFactory cacheFactory =
javax.cache.CacheManager.getInstance
().getCacheFactory();
CasheSitePolicy =
cacheFactory.createCache(Collections.emptyMap());
javax.cache.CacheManager.getInstance().registerCache
(CashSitePolicyID, CasheSitePolicy);
}
catch (CacheException e)
{
App.RecordLog(" --- CreateCashSitePolicyFailed --- " +
e.toString
());
}
}
But still I have same exception. Why? and What is proper counter
measure?
My app is chainofasker.appspot.com So if these data is not enough,
please refer to this location.
Thank you.

[appengine-java] Re: Failed to startup after ver 1.2.8 update
I updated ver1.2.8 at Dec-5th by seeing update request on Eclipse screen. But I was very surprised when I am seeing 1.2.8 is pre-release SDK and have no production environment by this post(=> hhttp://groups.google.com/group/google-appengine-java/browse_thread/thread/fe334c9e461026fa/b944b708a8d8de5b?lnk=gst&q=1.2.8#b944b708a8d8de5b) But this article was posted at Nov-25th and Display on the eclipse update recommendation and the Release Notes of Version 1.2.8 - December 3, 2009 (=>http://code.google.com/p/googleappengine/wiki/ SdkReleaseNotes) does not say anything about this. And So is it become official version at Dec-5th? If this is not official version Could you teach me when Google will make this version official and post old version(1.2.7) as a latest SDK. I must determine either wait official 1.2.8 or go back to 1.2.7 version to continue development. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

Thank you Shawn the information. Yes its like a official release I can breathe again. Then move back original question. "How should I teach Eclipse of this update?

[appengine-java] Java while statement bug on GAE server?
Now I am using GDataI for Java and I tried following code to get Google
document list
DocumentListFeed tempFeed;
tempFeed = myService.getFeed(feedUrl, DocumentListFeed.class);
After I confirmed this code work without problem, I change code as
following to be able to feed more than one page entry, but this code
create Null pointer Exception.
DocumentListFeed tempFeed;
tempFeed = myService.getFeed(feedUrl, DocumentListFeed.class);
resultFeed.getEntries().addAll(tempFeed.getEntries());
while((tempFeed.getNextLink() != null) &&
(tempFeed.getEntries().size()>0));
{
tempFeed = myService.getFeed(new
URL(tempFeed.getNextLink().getHref()),DocumentListFeed.class);
resultFeed.getEntries().addAll(tempFeed.getEntries());
}
I confirmed that “tempFeed.getNextLink()” is null. But this is a
condition to repeat while. I could not understand why this code fail
and I found suspicious info which related to Java while statement bug
in a following URL. Is this real bug?
http://java.decompiler.free.fr/?q=node/263 after I get info, I changed
my code as following and confirmed this code works without error.
DocumentListFeed tempFeed = this.resultDocListFeed;
DocumentListFeed resultFeed = new DocumentListFeed();
boolean okToFeed = true;
do
{
if(tempFeed != null && tempFeed.getEntries() != null)
{
if(tempFeed.getNextLink() != null && tempFeed.getEntries().size()>0)
{
tempFeed = this.docServiceClient.getFeed(new
URL(tempFeed.getNextLink().getHref()),DocumentListFeed.class);
resultFeed.getEntries().addAll(tempFeed.getEntries());
}
else
{
okToFeed = false;
}
}
else
{
okToFeed = false;
}
}while(okToFeed == true);

[appengine-java] Re: Java while statement bug on GAE server?
Sorry to use specific sample code. So I tried more basic following code.
try
{
int i =0;
boolean tempFlag = false;
while(tempFlag == true);
{
i++;
out.println("tempFlag" + i + ":=" + tempFlag);
tempFlag = false;
}
}
catch(Exception e)
{
out.println("Error" + e.toString());
}
what I got is "tempFlag1:=false" but out.print is within a
while(tempFlag == true) bock.
I think this is bug.
