[appengine-java] Re: datastore
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?

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

Hi all,
I'm trying to implement simple uploading.
The beginning of upload callback code looks as follows:
public void doPost(javax.servlet.http.HttpServletRequest request,

{
System.err.println(doPost on uploadImageFile);
BlobstoreService blobstoreService =
BlobstoreServiceFactory.getBlobstoreService();
blobstoreService.getUploads(request);
Java then throws an exception on the getUploads(request)-line (which
is lineno. 73):

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

Code:

ListString aliases;

query = pm.newQuery(Page.class);
query.setFilter(:aliases.contains(alias));
query.declareVariables(String alias);
ListPage results = (ListPage)query.execute(alias);
...
}
I want to select Page objects where the aliases property contains a
given alias String value. Is there any way to do this? I tried as
above and got an exception:
Problem with query SELECT FROM getimgs.Page WHERE :aliases.contains
(alias) VARIABLES String alias: Unsupported method contains while
parsing expression: InvokeExpression{[ParameterExpression
{aliases}].contains(VariableExpression{alias})}
If this cannot be done with JDOQL, the only solution I can think of is
selecting every Page object, then looping through them and using
Java's contains method, but this sucks somewhat.
Anyone?

Finbarr
