[appengine-java] [character encoding] request.setEncoding

2010-02-11 Thread K.Honsali

Salaam all;

Eclipse encoding is UTF-8 and HTML form charset is UTF-8.
Is it OK for this code below?

System.out.println(1-request char encoding :
+request.getCharacterEncoding());
request.setCharacterEncoding(UTF-8);
System.out.println(2-request char encoding :
+request.getCharacterEncoding());

executes like this:

1-request char encoding : null
2-request char encoding : null



I am trying to process arabic text as parameter coming from an html
form. The code worked fine in tomcat settings though...

[appengine-java] Precompilation Failure

2010-02-11 Thread Garry

Precompilation is failing and giving the following exception.  This is
from the SDK 1.3.1.  It did the same thing under 1.3.0.

com.google.inject.internal.ComputationException:
java.lang.SecurityException: Unable to get members for class
com.dynafocus.aws.s3.S3URLGenerator

The app runs fine without pre-compilation.

The class com.dynafocus.aws.s3.S3URLGenerator is a Scala class.  All
of the methods are public.  There are a couple of instance variables
that have getters and setters on them.

Please address because it takes about 20 seconds to fire up a load
request.  The app engine needs to keep these things in memory a little
longer than a minute.  I would be willing to pay for spot instances.

Sounds like a good start. Ideally the maven eclipse plugin [1] could
be configured to automatically generate the configuration for the
Google Plugin and M2Eclipse [2] picking that up as well. Also an
archetype would help quick starting. I assume you're aware that you
get the most benefit out of that only when there are up to date Maven
artifacts wit good metadata in a publicly available repo, preferably
Maven central.

Great, glad to hear it! I forgot to add a method to LocalServiceTestHelper
to set a custom app id. My mistake. I'll make sure this gets added for the
next release so you don't need to provide your own Environment
implementation.

public,but before 1.3.1 it's public!
In the JUnit document:

import java.io.File;
import com.google.appengine.tools.development.ApiProxyLocalImpl;
import com.google.apphosting.api.ApiProxy;

ApiProxy.setDelegate(new ApiProxyLocalImpl(new File(.)){});

So I can't new a ApiProxyLocalImpl instance!
Any body know how to use JUnit?
Thanks :)

[appengine-java] Workaround for like keyword in JDOQL

2010-02-11 Thread Piyush

Hi All,

I am developing a resource allocation application in GAE with Java.

Since there is no like keyword in JDOQL, I am unable to do search in
database based on a keyword. For example, I want to list all the
employees who have 'ash' word in their name.

I have already wasted 3 days due to this problem. So please suggest me
some workaround to achieve above this goal.

Thanks in advance.

Regards,
Piyush Jain

Hi there, I have something like:

public class User {

@Persistent
private String username;


But I couln't find a way of making work a query like select * from User 
where username = 'someUserName' from the admin console. It's driving me 
nuts!, Anyone has any idea how to do this? I guess it's supossed to be 
achieved with the KEY(..) feature, but I tried different ways and 
couldn't get it to work.

Re: [appengine-java] Setting the key of a child entity

Are both the parent and child persisted at the same time? If so, you can add
the child object as a child (not the Key) of the Parent object and call
makePersistent on the Parent.

On Thu, Feb 4, 2010 at 1:28 AM, Manny S manny.m...@gmail.com wrote:

 I am missing something simple here but can anyone point me to how I can set
 the child key before making the parent data persistent...(in a
 unidirectional one to one relationship)

 I create the parent data and the child data

 parentdata pdata = new parentdata('x','y', 'z');
 pdata.setKey(null);
 childdata child = new childdata('A');
 pdata.setChild(child);

 Now, I would like to set the child key as parent key + mystring

 When I try,
 String strparentKey = KeyFactory.keyToString(pdata.getKey());
 String strchildKey = strparentKey + details;
 Key childKey = KeyFactory.stringToKey(strchildKey);

 it gives me an error as the parent data does not have a key yet (cause is
 null)

 In this case the key of the parent is generated only when I persist. But I
 need to set the child key before I make it persistent. My application cannot
 generate an unique app id and I rely on the datastore to do it. As far as I
 can tell the KeyFactory.Builder does not have an option to generate unique
 keys and relies on the app to provide it and so I cant use that either.

 Any help would be appreciated...

[appengine-java] Blobstore UploadBlobServlet.java NPE

2010-02-11 Thread Stevko

I'm trying to post files into the blobstore on my dev station using
eclipse.
The _BlobInfo_ objects are appearing within the datastore viewer but
this exception keep getting thrown for the first time I post the form.

Is there anyone with access to UploadBlobServlet.java that can point
me to why I'm getting a NPE?

It sounds like what you want to do here is an ancestor query:

 How would you query/filter on ContactInfo when you have the Employee.
 Or better sample if it was Box and a Items, where you only want
 the yellow items.

[appengine-java] Updating an owned One-To-Many relationship (JDO)

2010-02-11 Thread Greg Harris

Hello,

I was experiencing problems very similar to the ones described in this
thread:
http://groups.google.com/group/google-appengine-java/browse_thread/thread/13473fcae300d845
where updates I made on my JDO objects weren't actually reflected in
the datastore. Taking the advice of an answer from that thread, I
tried closing and reopening the PersistenceManager in the following
order:

Initialize pm
Retrieve the parent object from the datastore using pm
Retrieve the list of child objects from the parent object (with a
simple method call)
Close pm
Re-initialize pm
Add a new child object to the list
Make the parent object persistent using pm

This actually works perfectly, as opposed to when the close and re-
initialization of pm are omitted, in which case the parent object's
list will not include the newly added child. However, because of this
closing of pm, I cannot put this entire update into a single
transaction, or an JDOUserException is thrown that tells me
'transaction is still active. You should always close your
transactions correctly using commit() or rollback()'. Everything works
fine if I separate this code into two transactions, but then it is
possible that two users interleave transactions such that they each
retrieve identical child lists from the same parent object, each add a
new child to that list, and the last to write will wipe out the child
added by the first. Any ideas or workarounds would be greatly
appreciated!

Thanks,
Greg

the system might be experimenting some technical dificulties, an if you

Re: [appengine-java] Workaround for like keyword in JDOQL

The usual approach to complex queries in GAE is to process your data
before you need to query it. So in this case for each person create
an index entity which simply contains a list of partial names e.g.
Pliyush, iyush, yush, ush

Then do a keys-only range query for the name part e.g. iyu (look
into how to do range queries). Then take the result key's parent and
look up the Person entity.

Re: [appengine-java] Anyway to check if current app instance is default version?


You could check the http host in the request to check for your live url

Basically we want to cache the pages with only the default version. We
want testers to hit the new version but won't effect normal users
using the default version.

Re: [appengine-java] Manipulate Blobs in Blobstore

2010-02-11 Thread bimbo jones

Thanks for the answer,

I have an async call that get's the url(string) from the blobstore api and
use that string directly on the form.setAction(...); then i show the button
to upload.The problem is that sometimes i get errors, is there some issue or
should i try to resubmit, or could the blobstore api be returning an invalid
url, i that case how can i check it? i sometimes get the 500 error.

Thanks

2010/2/11 Ikai L (Google) ika...@google.com

Not yet, though we are looking at interfaces for programmatically
interacting with blobs in the blobstore. Please star this issue:

If not is it possible to let the blobs from the datastore get more

is pretty low.

Re: [appengine-java] Precompilation Failure

Garry,

Can you send us your app-id (privately if you wish)?

Precompilation is failing and giving the following exception. This is

The app runs fine without pre-compilation.

The class com.dynafocus.aws.s3.S3URLGenerator is a Scala class. All
of the methods are public. There are a couple of instance variables
that have getters and setters on them.

Please address because it takes about 20 seconds to fire up a load

longer than a minute. I would be willing to pay for spot instances.

Re: [appengine-java] Re: Caching pages.

2010-02-11 Thread bimbo jones

Hey there,

I cached some html pages with tags like #MESSAGE# in a string, then used,
htmlstring = htmlstring.replaceall(#MESSAGE#,new message); then just
print the whole string.

BufferedReader in = new BufferedReader(new
FileReader(pagetobecached.html));
while (in.ready()) htmlstring= htmlstring+in.readLine();

Then you can cache/change it and print to the HttpServletResponse with a
PrintWriter, then when you need it later you just have to use (String)
cache.get(key); and voilá.
Hope this helps.

I have not coded much in native API but I think it will search first
for hello and then for world then mix results.

How tags property defined in your Model?
Is tags a property of Object entity of tags is property of Tag
entity linked with Object entity?

May be I have to try to code it in native API. Could you show some
sample code?

I have idea how to implement tags. It is expensive idea but it
should work with up to 6-8 tags per object.

I will post it in next post.

[appengine-java] Re: Tag search

Here is my tag search idea:-


If I have 4 tags

Then I can save following strings combinations

tag1,tag2,tag3,tag4,
tag1,tag2,tag4,
tag1,tag3,tag4,
tag1,tag4
tag2,tag3,tag4,
tag2,tag4,
tag3,tag4,
tag4,



class TagLine{
@PrimaryKey
@Persistent
Long id;

@Key
@Persistent
String tags;

@Persistent
Long objectId;
}



If I have search tag list  then I will implode tag list in a
string with comma as delimiter.
and search for tags (in TagLine) starting with that string

If I will have many tags that I will have to insert many TagLine
objects.

I estimate 2^(n-1) for n tags

So it is expensive feature and it is most efficient solution I have
found so far.



Sample search [tag3, tag2]
Sort: [tag2, tag3]
Implode into string tag2,tag3,


Object with this tags will have TagLine(s) starting with tag2,tag3,
In my sample data it is:- tag2,tag3,tag4,

[appengine-java] Discussion on will-it-play-in-app-engine

2010-02-11 Thread Spines

Hi,
I have an alternative for getting Spring forms working on the app
engine.  Instead of registering custom editors for your properties,
you can just comment out the offending line (a call to
findEditorByConvention) in the spring source code and recompile.

Everything will work fine as long your code doesn't rely on finding
custom property editors by naming convention.

I made a blogspot post with more details and also a recompiled Spring
jar with this modification. See 
http://www.answercow.com/2010/02/spring-forms-on-google-app-engine.html

No, it does a merge join - only returning entities that match all

A bit of a blast from the past on this thread, but...

I've always had a trickle of serialization problems in production
