Hi All,
I want to use the low level datastore, I looked at the documentation
and it looks ... complex.

Basically, I have a client program which needs to create tables and

Basically, I have a client program which needs to create tables and
their entities dynamically, so the columns would change over time.
This does not fit well with JDO as it works for fixed column entitys
that are annotated.
Not necessarily. Annotations are just one way of specifying what is
Hi group,
I have a problem with the Google Eclipse Plugin. I am developing an
application for the Google App Engine (Eclipse JEE Galileo, Google

I reinstalled the Google Plugin and Google App Engine SDK after I got

And do you have many projects mounted like I do? I had the same

No, all of my resources are local. They are attached to a SVN
repository, but the subversion plugin does not communicate with the
repository at that

Using GAE/J JDO, must one implement equals/hashCode based on non-

Hi,
Thanks guys for looking into this.
All requests to my app pass through a single servlet, say *Main*. So, I

variable to store session id :

Threads do not end when they finished serving a request. Instead they will
catch up another request in the queue and serve it.
So basically at the end of your service method of your servlet you should
explicitly set the
治本只能等GAE的升级了，这样确实只能保证你的应用不会因为两分钟没有请求被关闭！

Thanks for the report Steve, looks like a bug. The information in the error
message is still relevant though. The datastore does not support real
regular expression matching, but rather just startsWith filters. So, if
your regex can be rewritten to use GrpName.startsWith() then you can use

Thank you for the extra information. If you enable debug output for the ORM

without the second detachment, I recommend omitting the second detachCopy

I've tried this, but after 1 day, GAE recycled my instance every 40 seconds.
Then I used task queue to request my site per 30 seconds, but GAE

So I don't think it's a good way.
