Hi all,
Even after searching i am not able to see any correct answer on how to
work with GAE java dates.
My Model:
/**
*/
@Entity
@Table(name = testDetail)
public class TestDetail {
/**
*
*/
private static final long serialVersionUID = 1L;
/**
*/
@Column(name = spreadSheetName, length = 2000, nullable = false)
private String spreadSheetName;
/**
* The date the entity was created.
*/
@Column(name = created_on, nullable = false)
@Temporal(TemporalType.TIMESTAMP)
private Date createdOn;
/**
* The date the entity was last modified.
*/
@Column(name = modified_on, nullable = false)
@Temporal(TemporalType.TIMESTAMP)
private Date modifiedOn;
/**
*/
@Column(name = id, nullable = false)
@GeneratedValue(strategy=GenerationType.SEQUENCE)
@Id
private Long id;
//all setters and getters
}
And the dates in GAE datastore is stored in this format Sat Apr 23
18:25:28 UTC 2011
I am using JPA and my dao looks like this
public class TestDetailDaoImpl extends JpaDaoSupport {
@Autowired
public TestDetailDaoImpl(EntityManagerFactory entityManagerFactory){
setEntityManagerFactory(entityManagerFactory);
}
public ListTestDetailDetail findAllByDate(Date fromDate, Date
toDate) {
ListTestDetail testDetailList=null;//ListObject[]
try{
String query=Select from
+TestDetail.class.getName()+ where
createdOn=+fromDate.getTime()+ and createdOn +toDate.getTime()
+;
log.info(query);
testDetailList=getJpaTemplate().find(query);
log.info(testDetailList:+testDetailList);
}
catch(RuntimeException re){
re.printStackTrace();
throw re;
}
return testDetailList;
}
}
The above findAllByDate method always returns zero rows, even it has
data valid in it.
Can any one please tell me how should i handle dates in java.
Thanks

So I only use owned relationships when the child object can only exist under 1 (and only 1) parent. Hope this helped... it's only what I experienced... I'm not a JDO expert.

Do I need to create unowned relationships through Key or can I use some annotation (or something) to mark a field of type A as foreign key? When I make a field of type A in class B, and assign an object of class A to it, it is stored as new object as child of B :s 2. Can I use objectify for this use case only (mixing with jdo) and will it simplify stuff or not, any experience comment?

[appengine-java] Re: Stripes + UrlBinding + Google App Engine
Hi,
I use Stripes and DynamicMappingFilter on GAE production without
issues.
Here's the Stripes related part of my web.xml:

As you can see I don't use mapping for Stripes filter (setup long time
ago, don't remember why).
I hope this helps.

Hello
I am developing a Stripes webapp with Google App Engine. I have run into a
problem trying to implement clean URLs using Stripes' UrlBinding annotation
and the DynamicMappingFilter.
I have configured my action to answer to URL /hoblaa i.e. I have a
@UrlBinding('/hoblaa) in my ActionBean. This result apparently in some
sort of a redirect loop. The address bar looks like this
/hoblaa/;jsessionid=lr9opztbd98s and the page could not
be served.
ActionBeans without the @UrlBinding work as expected.
Also, what strikes me odd, is that in my development environment (running
the app locally on eclipse) the @UrlBinding works OK and /hoblaa does what
it is expected to.
The DynamicMappingFilter document says that checks for 404 and then tries to
find appropriate ActionBean for the URL. Could it be that App Engine does
not like this sort of a method?
My filter/servlet mappings in the web.xml are (ommitted the servlet and
filter declarations):
servlet-mapping
servlet-nameDispatcherServlet/servlet-name
url-pattern*.action/url-pattern
/servlet-mapping
filter-mapping
filter-nameStripesFilter/filter-name
url-pattern*.jsp/url-pattern

/filter-mapping

url-pattern/*/url-pattern
dispatcherREQUEST/dispatcher
dispatcherFORWARD/dispatcher
dispatcherINCLUDE/dispatcher
/filter-mapping
I would greatly appreciate some insight on this. Is it an App Engine
specific issue or have I configure something wrong? I don't think I have
misconfigured anything since all is fine in development environment, but who
knows.

[appengine-java] Multitenancy / Billing and Versions..
Hi! I am currently building an application. This application will be licenced to clients and they will be charged for this. (as far everything is normal) First I thought I could deploy an application for each client but I've read it's against Google policy. So I am now willing to use the multitenancy support. I would need to charge more a client because he use more ressources. 1) So How can I know how much ressources a client consumes? 2) If I want to upload a new version of my application but want to let clients choose if they want to upgrade it or not; is it possible? Thanks! Stephane P.S.: Wouldn't it be simpler to offer the opportunity to also deploy several similar apps (with the benefice of keeping fine grain control) but share the costs instead of doing only one app??? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Blobstore vs. Datastore for HTML files
I have an app that stores XML and HTML files, and i'm trying to decide on the Blobstore vs. Datastore Pro for Blobstore: it is possible for the HTML files to exceed 1 MB (although I have ready the average size of an HTML file is ~25 KB) Pro for Datastore: The blobstore allows for insert / deletes only, no updates. So I would have to delete blobs and insert new blobs every time a user saves an existing file, which could happen a few time a minute (similar to editing a file in Google docs) From a technical perspective, are there any repercussions to: a) serving HTML files from the datastore vs. b) serving HTML files fro the blobstore, but constantly having to add and delete blobs? -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

One more thing. Blobstore is 1/3 the cost of High Replication datastore. So if you don't need to index the information, and you are okay doing multiple GET's/PUTs (ie one GET to get the blobkey, and one more to actually serve the file), and your code allows the inclusion of the blobstore, then the blobstore may be an attractive option. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] Re: Blobstore vs. Datastore for HTML files
Good question. You can have multiple object until the object limit. On May 5, 2011 4:58 PM, bradr brad.rydzew...@gmail.com wrote: Question, if I opt for datastore ... I noticed that certain types (ie datastore.Blob and datastore.Text) can be up to 1 megabyte; not indexed. Can I have multiple 1mb text columns? Or is there an overall size limit for the row?

[appengine-java] Re: Blobstore vs. Datastore for HTML files
Entity limit is 1MB total. But you could have multiple blobs within one if they where less than 1MB.
