Thanks Scott, Miguel. For now I am deploying manually and that seems to work. Miguel - thanks for the link to the FAQ.

[appengine-java] Eclipse plugin - prevent auto-copy of jars
Hi, I'm using Objectify for persistence and I'd really like to remove all jdo / jpa related jars from my lib directory but eclipse keeps transferring them back. I also tried modifying the contents of the com.google.appengine.eclipse.core file under the .setting directory but I guess eclipse overwrites my changes on startup and then copies over the jars anyway. I've seen discussions where people have used the appcfg tool to manually deploy instead of doing so from within eclipse but I'm hoping a better solution exists. This blogpost http://www.answercow.com/2010/03/google-app-engine-cold-start-guide-for.html claims that startup times reduce by ~400ms by removing these jars and I really love speedups especially when they are free :-). Perhaps someone from Google can comment on whether removing these jars will actually speedup apps even if the app does not directly use them. Also, I am not sure which jars need to be retained for sure and I'd really appreciate it if someone could could give me a pointer regarding this. I am pretty new to Java so apologies if this is a naive question.

Thank you very much for pointing me to Twig. I'll play around with it
this weekend and get back to you if I have any questions.

Re: [appengine-java] Re: How to use junit test in the newest SDK1.3.1
It's the same (attached) I used before update to 1.3.1.
Thanks,

TestEnvironment.java
Description: Binary data
[appengine-java] Re: How to use junit test in the newest SDK1.3.1
Ok!
But when I'm using transactions I'm getting:
java.lang.NullPointerException: No API environment is registered for
this thread.
at
com.google.appengine.api.datastore.DatastoreApiHelper.getCurrentAppId(DatastoreApiHelper.java:
67)
at
com.google.appengine.api.datastore.DatastoreServiceImpl.beginTransaction(DatastoreServiceImpl.java:
270)
I've tried to extend LocalServiceTestHelper and overwrite
newEnvironment() with my Environment (who returns appId) but it
didn't work...
What's wrong?
Thanks,
Krishna
