[appengine-java] Re: Unsupported method while parsing expression:

[James M]

Hey Google,

If that really is a mistake in the documentation that Ftaylor pointed out, 
can you take the 5 minutes and update it?  That 5 minutes sure would pay 
lots of dividends on the other side in terms of saved minutes trying to 
figure out why things aren't working.

The documentation is posted here:  
http://code.google.com/appengine/docs/java/datastore/jdo/queries.html#Introducing_Queries

In the Query Filters section, the example shown contradicts the JDO spec 
according to Andy's response. 

Now, if the documentation is correct, then I'm just confused, and I'll just 
crawl back into my computer screen and continue beating my head against 
this stuff until it makes sense. However, if it's not correct, can we get 
someone to update that please? It's been 3 years now. :)

Thanks,
James

Re: [appengine-java] How to initialize class guestbook.PMF ?

Hi,

This might be a good question for StackOverflow. We're trying to migrate
these types of questions over there:

https://groups.google.com/forum/#!topic/google-appengine/Z6XN_64cA7w

Likely:

1. It doesn't exist
2. You are importing it incorrectly

[Ikai Lan (Google)]

Hi,

I've sort of "soft closed" this group. I was supposed to put it into
read-only mode a week ago, but I wanted to see if questions would still
trickle in.

This type of question seems pretty good for StackOverflow, where we're
increasing our efforts to grow the community there. Try posting it and see?

[appengine-java] Re: getUploads() on blobstoreService not found

[Drew Spencer]

UPDATE: Found a solution here:  
http://stackoverflow.com/questions/9079431/appengine-blobstore-cant-upload-blobs-since-update-to-1-6-1-from-1-5-5-getuplo

The files on my build path were fine but I needed to clear out the 
WEB-INF/lib folder of all of the old ones.

Happy coding!

[appengine-java] Re: datastore

[Ian Marshall]

I think that you will have to put more effective effort into posing
your question to get a useful reply.

What datastore persistence interface do you want to use? What is your
datastore design, using which you want to store a string? What web
framework do you want to use, if any?

Have you read some of the GAE/J documentation? If "No", then you
should. If "Yes", then on which part(s) are you stuck?
