[appengine-java] Need GAE logs explanation
Hello everybody, I dont really understand the logs GAE shows me in the admin console : I have a first URI showing a simple search form that gives me : 09-24 08:24AM 30.341 /default/ftsearch.do?_contenttype_=content 200 117ms 103cpu_ms 73api_cpu_ms But my servlet service method lasts only : INFO : com.mably.cms.web.DispatcherServlet service: 6ms And I have a second URI listing data from the datastore that gives me : 09-24 08:24AM 28.575 /default/notifications.do 200 38ms 27cpu_ms 13api_cpu_ms INFO : com.mably.cms.web.DispatcherServlet service: 10ms What's annoying me is that the fastest (6ms versus 10ms) servlet seems to last longer for GAE (117ms vs 38ms) and to take more CPU.

If so, what's likely happening is that you're not including your app initialization when you only time the service method of your servlet.

I haven't found a way to set a Content-ID header on a mimebodypart/

is quite rudimentary (only filename and data).
May be some part of the low level API are still undocumented ?
Thanx for all.

There's one last thing you may want to try:
http://code.google.com/appengine/docs/java/javadoc/com/google/appengi...
The above page documents the Low-Level API. Try creating an email object via
that API, setting the Content-ID of the attachment and the HTML tag to point
to the cid. You're already doing that in the example you sent using
javax.mail, but I'm wondering if the low-level API is capable of doing this.
If not, I'll open an issue.

Any chance to see this bug fixed in the future ?
Is there any documentation on the meaning of Converting
attachment data failed error message ?
On 19 nov, 20:55, Ikai L (Google) ika...@google.com wrote:
Looks like you're right. As far as I know there are no hidden methods.
Another workaround for this limitation could be to store incoming images in
the data store on an incoming email, then reference them in the emails that
get sent out. It's not ideal, but it may be the solution to what you are
looking for.

That's good information to know. We are not using Sun's JavaMail

There's one last thing you may want to try:
http://code.google.com/appengine/docs/java/javadoc/com/google/appengi...
The above page documents the Low-Level API. Try creating an email object
via
that API, setting the Content-ID of the attachment and the HTML tag to
point
to the cid. You're already doing that in the example you sent using
javax.mail, but I'm wondering if the low-level API is capable of doing
this.
If not, I'll open an issue.

[appengine-java] Re: Local datastore is empty after migrating to 1.3.1
Same thing happened to me. Got an empty local datastore after updating to 1.3.1. Hopefully I didn't have much data in it. But it might not be the case for everybody.

[appengine-java] Re: Datastore migration
If you need an integrated backup solution in GAE, please star issue : http://code.google.com/p/googleappengine/issues/detail?id=776 On 2 fév, 19:22, Moritz mor...@cloudme.org wrote: Hello everyone, after a couple of versions of my application I found out that I need to change the datamodel fundamentally in order to achieve better performance. My approach was as follows: (Coding) - Mark all old API as @Deprecated - Create new classes etc. - Update views etc. - Develop a migration servlet which copies data from the old model to the new model (Migration) - Deploy new app - Call migration servlet URL All tests on my local development environment were successful. The new datamodel is less complex than the old one, it contains only implicit relations and stores large data in a separate entity. That perfectly matches the application's scope, only minor refactorings were necessary to implement the new datamodel. However, the migration failed. Of course, I had already so much data in the system, that the request timed out. Now my datastore is half old and half new. Bummer. Luckily, that application is not really in production, so it is not a fatal loss. However, I'm wondering how such migration is usually done. - How do Ibackupmy datastore? - How do I run migration scripts (in my case =servlet)?

[appengine-java] Help needed : found more than 100 URLMap entries in application configuration
I'm hitting the Found more than 100 URLMap entries in application configuration limit. What is strange is that I have only 82 url-pattern definitions in my web.xml (many servlets). Is it possible to have it increased by someone at Google? My app ID is webwinewatch. Any help will be greatly appreciated as I can't deploy my app anymore. Thanx in advance. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.
