I was just trying retrieve a List of entities and do a .size() to get a
current count, but ran into this:
Caused by: java.lang.IllegalArgumentException: can't operate on multiple
entity groups in a single transaction. found both Element {
type: "Conversation"
id: 37
}
and Element {
Interesting. Can you post app IDs and keys of entities that do this?

If you're talking about the blobstore, you should read this doc:
http://code.google.com/appengine/docs/java/blobstore/overview.html
If you're talking about a datastore blob, you would read it as an
inputstream and translate it downstream in a servlet.

iText is listed therein as not supported - as are many packages that
rely on the AWT framework / Graphics 2D. Google App Engine is here
like most other "headless" environments.

I realized the same. But the local datastore is primitive when it comes to
features as compared to the one in production. For example you cannot edit

In the last couple of days my application can not start in less than 30s

At other times the application starts normally and I can not see a reason in
