Hi Guys,
I tried Betwixt from apache(http://commons.apache.org/betwixt/index.html).
And it works out of box. I only got into some problems as i downloaded some
older version of dependecies(Digester and beanutils).
So when using Betwixt make sure you have latest version of all dependecnies.

Hi,
Following is a snippet of JDO class:

private ListString Groups;

There appears to be a memory leak with the memcache implementation on the
dev server; I've opened a new issue for this:
http://code.google.com/p/googleappengine/issues/detail?id=2428
I have some testcases that make heavy use of memcache that are failing due
to this issue.

You are using a Java Runtime Environment (JRE) which does not include a

You have to use a JDK instead.

Toby's email is correct. The correct way to read from an InputStream is to
create a buffer of bytes, then iterate over it. You should be doing
something like this:
while ((len = stream.read(buffer, 0, buffer.length)) != -1) {
output.write(buffer, 0, len);
}

If the classes are being loaded from UserClassLoader from a jar in your

that manifest. If that's not what you're seeing, please file an issue in the

You can use the makePersistentAll() method of PersistenceManager to batch
put items. See here:

This was introduced in SDK 1.2.5.

The filesystem is read only on app engine; would trying to create a file, in
WEB-INF for example, work? I'm wondering if there are corner cases I'm not
thinking of where that might fail and falsely report that you're on app engine;
for example, if you were doing integration tests under Hudson.
Looking through my logs, it seems like just about every call for
UUID.randomUUID() takes about 5 seconds. Is there a better way to
generate UUID's than this when using the app engine?
I know at least some of this is from an inactive app (there are a few
minutes between most requests), but it
Ikai,
Thanks for the response. The issue is that I have two types of objects
that need to be persisted:
(1) a bunch of JDO managed objects
(2) a bunch of low-level Entity objects.
Is there any way that I could batch put all of them at once through
the same API rather then calling the JDO api
Do you have actual timing code around that one single call, or is other
stuff going on during your request? If you can create a trivial webapp that
consistently shows 5 seconds just to call UUID.randomUUID() please file an
issue for it, and we can look into it.
On Tue, Nov 24, 2009 at 9:19 PM,
No, there is no easy way to throw them all in. If this is a performance
bottleneck, you could always write converters for each of your JDO managed
entities.
