[appengine-java] Re: Discussion for Best Practices For App Engine With Example
This is not quite an example, but a rather complete file listing,
along with specs And your question was?
Sorry I don't want to be negative, but your post is so long!

Hello all
I am working on a project which has following
requirements.Actually this is not real project .I am used to work with
relational DB`s and for future projects I want to use GAE.Through this
project I just want to learn best ways to use GAE .
It is basically implementation of discussion groups(Same as forums on
different sites).In the website users can discuss different topics
with friends and other users of the website.So I have to implement
following features.
1) User can have many friends.
2) Each user can create multiple discussions.
3) Each discussion will have participant in it.
4) If there is any update in the discussion then participants of the
discussion will get notifications.
5) A user can observe his friends by adding them to his observed
list.if an observed person creates any discussion a notification will
be sent to his observers.
6) Any user can view list of his observers and list of users he/she is
observing.
7) Every user can create his profile on website .He can put his
picture ,title and tags.
8) Every discussion will have profile on website .It will have
picture ,title and tags.
9) Any user of the website can search people or discussions based on
the tags associated with the users and discussions.For example If user
A has 3 tags in his profile like cooking,continental and Asian and
user B has cooking and Asian in his tags and there is discussion named
D1 on website which has tags continental and chines then if any user
search for keyword continental user A and discussion D1 should come as
search results.
10) If a user has created a discussion all the participants of that
discussion will be added to his work group.For example let us say
there are 4 users A,B,C,D and A creates a discussion named D1 and add
user B,C in it.then work group of A will have B and C in it. Work
group of B will have A and C in it.Work group of C will have A and B
in it.Now if user D creates discussion named D2 and add C as
participant in it then work group of D will have C in it.work group of
C will now have A,B and D in it.In other words work group is list of
all the users with whom a user is participating in any discussion.
Its GUI will be as below
1) After log in, user Home page will be shown.On the home page there
will be right bar and main content area.
In the right bar we will show
a) His 10 recent active friends along with link to see all his
friends list and total count of his friends.
b) His 10 recent discussions created by him with link to see list
of all discussions created by him and total count of his discussions.
c) 10 recent discussion in which he is participant with link to
see list of all discussions in which he his participant and total
count of his discussions.
d) 10 recent active user to whom he is observing along with link to
see list of all observed user and total count of user observed.
f) 10 recent active user who are observing him along with link to
see list of all his observers and total count of users observing.
g) 10 recent active users from his work group along with link to
see list of all the users in work group.(Work group is list of all the
participants of all discussions in which user is participating) and
total count of his work group.
In the Main Content we will have
a) Initially after log in it will display all the notifications of
the user.
b) If user click on any link in the right bar then result of that
action will be displayed in main content.
To implement this I have written following entities.I do not know
whether it is the best way to do it .Please help me to know how we can
improve this .
I am planing to keep Discussion , Message , Workgroup , Notification
in one entity group.

For your information, my work-around was of the form: ... WHERE ... (dtDate null) (dtDate p1)// p1 is a parameter which is very similar to J Robert Ray's work-around. Is it possible for the GAE/J query documentation to be amended to mention the treatment of null values in inequality filters as Max Ross mentioned in the above thread, in order to save others time in the future?

[appengine-java] Another Blob to Image Question
Hello
I'm building a servlet to display an image - nothing new here. The
problem I'm facing is that the image is being forced to download in
the browser instead of being displayed on the page. I've tested in
Chrome/Firefox and IE.
When the image is downloaded the file size is correct, but the file is
downloaded with the filename the same as the requesting page
(getimage). And the type application/octetstream. I do set the content
type in the getImage servlet.
The code steps:
0. Call the getimage servlet from jsp
1. retrieve the image info - blob and content type. The query uses the
current user to fetch the image from the datastore so on url params
are needed in this case.
2. Explicitly set the content type of the response
3. Write the blob as bytes into the output stream
The code:
#0. profile.jsp
img src=/getimage
#1-3 #Servlet_GetImage.java
public class Servlet_GetImage extends HttpServlet {
private static final Logger log =
Logger.getLogger(Servlet_GetImage.class.getName());
public void doGet(HttpServletRequest req, HttpServletResponse resp){
UserService userService = UserServiceFactory.getUserService();
User user = userService.getCurrentUser();
if(req.getParameter(imageId)==nulluser!=null){//we will
fetch
the profile image - no imageId params are needed the user must be
logged on
DS_ProfileImage myImage =
(DS_ProfileImage)ProfileImage.fetchImage(user);
if(myImage!=null){
try{
resp.setCharacterEncoding(myImage.getContentType());
resp.getOutputStream().write(myImage.getBlob().getBytes());
}
catch(Exception e){
log.warning(ERROR: +e.getMessage());
}
}
}
else{
//TODO: create a fetch image method for images other
than Profile
images
}
}
}

[appengine-java] Java Heap Space Error, Correct Increasing Method?
Hello all,
Im working on a project that reads GTFS archives as part of its
functionality. When we are importing
a particular set of data that has ~60,000 entries my dev server locks
up around the 27,000 entry. The
error is the java heap space error. I would like to know if anyone has
successfully upped their heap
space. I searched, and found general instructions but after
implementing them I'm still failing around
the same entry. This is leading me to believe that my command line
args are not taking affect. Here
is what I have so far:
appengine-sdk-java/bin/dev_appserver.sh:
#!/bin/bash
# Launches the development AppServer
[ -z ${DEBUG} ] || set -x # trace if $DEBUG env. var. is non-zero
SDK_BIN=`dirname $0 | sed -e s#^\\([^/]\\)#${PWD}/\\1#` # sed makes
absolute
SDK_LIB=$SDK_BIN/../lib
SDK_CONFIG=$SDK_BIN/../config/sdk
java -Xms1024m -Xmx1024m -ea -cp $SDK_LIB/appengine-tools-api.jar \
com.google.appengine.tools.KickStart \
com.google.appengine.tools.development.DevAppServerMain $*
Is this correct?
Also the way we get our data is through a custom import function that
chunks the data into groups of 20
and then processes them and stores them into the datastore. We are
only using one instance of the
persistance manager as per the recommendations to use a singleton
class. Each batch hits a servlet on
our app and then does its work. Should we close the persistence
manager after every batch is completed?
I'm wondering if this would be a memory leak.
Thanks,
-Mike

[appengine-java] Re: Any ETA for a backup/restore facility?
Mscwd01, I'm not a google employee, but I have had success backing up our datastore and then restoring our datastore with the bulkloader utility. Currently the bulkloader is in the python sdk, so all you need to do is download that and then youll be able to do backups and restore from those backups. Check out the literature on the app engine, and try a couple searches to get your bearings. Nick Johnson has commented or written every search result that comes back when I was researching this a couple of weeks back, and there is also an I/O video on the bulkloader. Make sure you read some of the fine print, i.e. one caveat is that you must have had your datastore populated for at least 12 hours which is the amount of time it takes for the statistics info to be built. That what the bulkloader works off of to do its datastore dump. - Mike On Jun 28, 7:16 am, mscwd01 mscw...@gmail.com wrote: Hey Google Employees, There has been a backup/restore facility on the roadmap for a while now.

FWIW, I've been looking for a solution to this myself. I generally need to automate and bulk uploads to my app on a daily basis.

So, the solution that I have found that seems to work is to create your own bulk uploader via the FileUpload example from here: http://code.google.com/appengine/kb/java.html#fileforms And you can then use python's poster library to post files to your app. You will still need to figure out how you want to handle administrative privileges.

You need to supply --jvm_flag as a command-line argument to dev_appserver.sh

dev_appserver/ task. (You can see this in config/user/ant-macros.xml).

As for the Linux box, the default heap size is different depending on
whether you have a server-class machine or not, so it is possible
that you
are seeing a much higher default heap size just by virtue of using a
machine
with more RAM or more processors.
The -Xmx setting you added to dev_appserver.sh has no effect. Your
code is
executed in a subprocess, which is why --jvm_flag must be used to pass
Java

Hello all,

Is this correct?
Also the way we get our data is through a custom import function
that
chunks the data into groups of 20
and then processes them and stores them into the datastore. We
are
only using one instance of the
persistance manager as per the recommendations to use a singleton
class. Each batch hits a servlet on
our app and then does its work. Should we close the persistence
manager after every batch is completed?
I'm wondering if this would be a memory leak.
I believe our documentation recommends storing the
PersistenceManagerFactory
as a singleton, but using a new PersistenceManager each time
(remembering
to
close it before discarding).
However, the local implementation of the datastore does keep
everything
in
memory (and simply flushes to disk periodically), so you will run
into
size
issues at some point.

[appengine-java] Re: Java Heap Space Error, Correct Increasing Method?
Solved!
Okay here is a quick format for how to increase your java heap space:
If you are running your dev server by running ./dev_appserver.sh war
dir then do this:
#!/bin/bash
# Launches the development AppServer
[ -z ${DEBUG} ] || set -x # trace if $DEBUG env. var. is non-zero
SDK_BIN=`dirname $0 | sed -e s#^\\([^/]\\)#${PWD}/\\1#` # sed makes
absolute
SDK_LIB=$SDK_BIN/../lib
SDK_CONFIG=$SDK_BIN/../config/sdk
java -ea -cp $SDK_LIB/appengine-tools-api.jar \
com.google.appengine.tools.KickStart \
com.google.appengine.tools.development.DevAppServerMain --jvm_flag=-
Xmxmem size here $*
*** Notice where the --jvm_flag is !
If you are using ant runserver then you need to edit appengine-sdk-
java/config/user/ang-macros.xml :
Find this, and add an arg value:
macrodef name=dev_appserver description=Runs the App Engine
Development App Server
attribute name=war description=The exploded war directory
containing the application/
attribute name=port default=8080 description=The port the

Nick Johnson has commented or written every search result that comes back when I was researching this a couple of weeks back, and there is also an I/O video on the bulkloader. Make sure you read some of the fine print, i.e. one caveat is that you must have had your datastore populated for at least 12 hours which is the amount of time it takes for the statistics info to be built.
