Hi,
Docs say Everything the servlet writes to the standard output stream (
System.out) and standard error stream (System.err) is captured by App Engine
and recorded in the application logs. Lines written to the standard output
stream are logged at the INFO level, and lines written to the standard

Thanks a lot, it worked.
I guess there was some problem with Google Plugin, it didn't replace the
jars when I updated my sdk version.

1. Hi,
I am getting following error while trying to setup

I tried same test case with a boolean value

private Boolean bool = true;
and the value (bool) is not changing to null after detaching the
entity. why there is difference in behavior? Is detaching an entity is
necessary? What are the losses if I cache an entity

Hi,
I have designed my app to keep data (within servlet env.) for all previous
requests. For each request it will first search the data in servlet env.
store, if it doesn't find the data here it will fetch data from datastore
and append the same to servlet env. store. So, if the same servlet
yes, you are right.
But, in my case, suppose each request requires 100 entities to be fetched
and for any two requests say 90-95 entities are common. So, if I use only
memcache for caching, 100 memcache fetch will be required per request. Or,
if I keep the data in servlet env. for each req., 10-0
Thanks Don for clarification.
100MB seems sufficient for me. Please suggest me a library for LRU caching
implementation.

Hi,
I know some cases where serialization is required, one is MemCache. Let, I
cache some object in Memcache and later do some changes in class, the cached
object will fail to typecast to its (updated) class type. Now suppose I have
set serialVersionUID in my serialized class, will it still fail

Hi,
Thanks guys for looking into this.
All requests to my app pass through a single servlet, say *Main*. So, I
thought I need not to add additional filter and I used a ThreadLocal
variable to store session id :

impression that passing an entity into makePersistent re-attaches the
